拓展资料

一、关于罗马数字

1、是欧洲在阿拉伯数字(实际上是印度数字)传入之前使用的一种数码,现在应用较少。它的产生晚于中国甲骨文中的数码,更晚于埃及人的十进位数字。但是,它的产生标志着一种古代文明的进步。

2、常见用途

(1)最常见的罗马数字就是钟表的表盘符号:Ⅰ、Ⅱ、Ⅲ、Ⅳ(IIII)、Ⅴ、Ⅵ、Ⅶ、Ⅷ、Ⅸ、Ⅹ、Ⅺ、Ⅻ……

(2)元素周期表:IA族,IIA族,IIIA族,IVA族,VA族,VIA族,VIIA族,IB族,IIB族,IIIB族,IVB族,VB族,VIB族,VIIB族,VIII族。

(3)对应阿拉伯数字(就是现在国际通用的数字)、就是 1、2、3、4、5、6、7、8、9、10、11、12……(注:阿拉伯数字其实是古代印度人发明的、后来由阿拉伯人传入欧洲、被欧洲人误称为阿拉伯数字。)

二、记数方法

1、相同的数字连写、所表示的数等于这些数字相加得到的数、如:Ⅲ=3;

2、小的数字在大的数字的右边、所表示的数等于这些数字相加得到的数、 如:Ⅷ=8、Ⅻ=12;

3、小的数字(限于 I、X 和 C)在大的数字的左边、所表示的数等于大数减小数得到的数、如:Ⅳ=4、Ⅸ=9;

4、正常使用时、连写的数字重复不得超过三次;

5、在一个数的上面画一条横线、表示这个数扩大 1000 倍。

三、组数规则

有两条须注意掌握:

1、基本数字 Ⅰ、X 、C 中的任何一个、自身连用构成数目、或者放在大数的右边连用构成数目、都不能超过三个;放在大数的左边只能用一个;

2、不能把基本数字 V 、L 、D 中的任何一个作为小数放在大数的左边采用相减的方法构成数目;放在大数的右边采用相加的方式构成数目、只能使用一个;

四、对照举例

1、个位数举例

Ⅰ-1、Ⅱ-2、Ⅲ-3、Ⅳ-4、Ⅴ-5、Ⅵ-6、Ⅶ-7、Ⅷ-8、Ⅸ-9

2、十位数举例

Ⅹ-10、Ⅺ-11、Ⅻ-12、XIII-13、XIV-14、XV-15、XVI-16、XVII-17、XVIII-18、XIX-19、XX-20、XXI-21、XXII-22、XXIX-29、XXX-30、XXXIV-34、XXXV-35、XXXIX-39、XL-40、L-50、LI-51、LV-55、LX-60、LXV-65、LXXX-80、XC-90、XCIII-93、XCV-95、XCVIII-98、XCIX-99

C-100、CC-200、CCC-300、CD-400、D-500、DC-600、DCC-700、DCCC-800、CM-900、CMXCIX-999

4、千位数举例

M-1000、MC-1100、MCD-1400、MD-1500、MDC-1600、MDCLXVI-1666、MDCCCLXXXVIII-1888、MDCCCXCIX-1899、MCM-1900、MCMLXXVI-1976、MCMLXXXIV-1984、MCMXC-1990、MM-2000、MMMCMXCIX-3999

Now I would like to recommend to you the writing and planning of the planning book.
Results oriented project planning
Judging whether a public good project plan is standardized, it mainly depends on whether it can answer the five questions clearly: first, what kind of social problems to be solved by the project, that is, why to do this project; second, who is the object of the project, that is, who is the project; and third, what the project meets the object of the service Demand; fourth, what is the goal of the project and how to measure it; fifth, how to implement the project, that is, how to do it and what to do.
These five questions and responses constitute a very rigorous logic framework for thinking. The order of the 5 problems can not be reversed and the elements can not be lacking. If you can use this thinking logic to work out a project plan, it can not only make the project more effective, but also help the project to develop a habit of improving the effectiveness of thinking.
We can find that the first 4 problems in this framework are related to project results. Peter Deruk, a famous management guru, puts forward: "nonprofit organizations exist for achievements." "Project output model" is a piece of information provided by the United States joint recruitment. There are 4 very important concepts: input, activity, output and results. Investment refers to the resources consumed in the project or by the project; activity refers to the purpose of fulfilling the mission to achieve the goal of the project and the use of the input; the output refers to the direct output of the project activity; the result refers to the changes and benefits acquired by the service object after the service. One of the purposes of the United States joint recruitment is to tell the non-profit organizations that apply for funds to obtain funding that must be fruitful. If there are only activities and outputs in the project plan, no results can be obtained.
But at present, there are many misunderstandings in many social service institutions' project plans that regard activities as projects and outputs as achievements. The result must be the benefit and change of the service object. Therefore, activity is not a result, the number is not a result, and the satisfaction of the service object is not a result. Satisfaction is a subjective feeling, and does not reflect the benefit and change of the service object.
There are three special tips on the results: first, the results of the project are reflected by the object of service; second, the results of the project should be reflected by the changes and benefits of the service objects; and third, the results of the project must have a quantifiable evaluation index. Nowadays, some social service organizations often win awards by their own projects or are reported by the media as results. It is also a mistake to take awards and media reports as project results. Some prize winning projects are actually not projects, but activities, and nothing has happened. To be a public welfare project, we must really focus on the results, focus on effective solutions to social problems, and benefit the clients.
We must have a mindset to pay attention to public welfare projects. Before making a project, do not consider how the project is done and what it does. First, we must understand what the outcome of the project is. Only by knowing what is the result of the project can the project results be seen clearly in the project plan, and the higher the possibility of obtaining funding. The former chief executive officer of the United States, the world's largest girl child camp, the world's largest girl's organization, which emphasizes female leadership, fostering girls' morality, setting up girls' confidence, and providing other learning and working skills, is proposed by the former chief executive and founder of the Drucker foundation, Francis Hessen. The organization of the measurable results can go to the future. Similarly, for a social service organization to achieve sustainable development, it is necessary to have measurable results and to continue to achieve measurable results. This is also the reason why we must attach great importance to and reflect the results in formulating public welfare projects.
Correctly determine project goals and evaluation indicators
Clarify what is the outcome of the project, next, we need to know how to determine the objectives and evaluation targets of the project. Project achievement actually refers to the goal of the project, that is, what kind of results should be achieved after the project is made. When writing project plans, we must first determine specific targets according to the service objects of the project. At the same time, based on specific objectives, we should determine the assessment indicators to measure whether these specific objectives can be achieved.
Drucker put forward: "the results of any organization can be measured by two standards of quantification and qualitative analysis. These two standards are intertwined and interact with each other. If you want to understand how an organization can change people's lives and change their lives, it is necessary to understand these two indicators. It is worth reminding that social service institutions must pay attention to setting goals and setting evaluation targets, and at least one of them must be quantitative. If the project plan contains only qualitative objectives without quantitative objectives, this goal needs to be adjusted and optimized.
A good project goal has 5 characteristics, that is, it must comply with the principle of SM A RT. First, simple and easy to understand. Project objectives must be simple and clear. Don't write empty and abstract. You can know clearly what kind of results you want to see at first glance. Second, the results can be measured. Goals are measurable and can be measured by quantitative indicators. Third, I can do what you can. This goal can be achieved through efforts. Fourth, it is in accordance with the interests. The objectives identified by the project,
