Government Publications are published to keep records of governmental activities and performances. In a rapidly changing information-oriented society, it is badly required for the operation system of government publications and a library to be effectively managed with government publications for satisfying 'right to know' of people and improving the obligation of government to 'let people know.' Accordingly, the purpose of this paper is to analyze such five research items as the situation of the publication and distribution of, government publications, the operation system of the publications in library, the number of publications regarding secondary information sources for the publications, and the legal deposit of the publications in the National Library, in order to proceed with a subject as to how much the government publication is satisfying 'right to know' of people. The research findings were suggested as follow : 1) Despite the fact that the publication of government publications has been gradually increased every year in numbers and kinds, it is unfortunately pointed out that the publications, distributions and sellings of them were not well organized and systematic. That is, the government publications had not been published more than 1.47% of all publications in number. Moreover, more than the half of the publications were non-periodically or annually published. To make the matter worse, it was not easy to get an access to the publications because of the publications not to be sold. 2) It a n.0, ppears that people could not use the publications efficiently because the library and administrative document office did not pay sufficient attention to public relations for all sorts of government publications. Not only that, there were not enough numbers of publications regarding such secondary information sources as bibliography, index and catalog. A speedy searching capacity for the information gave rise to another serious problem which the government publications could not be effectively used. 3) It is legally stated that all sorts of government publication should be deposited to the National Libraries. However, the law was not properly put into force because of lack of understanding of government agencies about the law.

Mobile P2P(Peer-to-Peer) protocols in MANET(mobile ad-hoc networks) have gained much attention recently. Existing P2P protocols can be categorized into structured and unstructured ones. In MANET, structured P2P protocols show large control traffic because they does not consider the locality of P2P data and unstructured P2P protocols have a scalability problem with respect to the number of nodes. Hybrid P2P protocols combine advantages of the structured and unstructured P2P protocols. Cluster-based P2P protocol is one of the hybrid P2P protocols. Our study makes an analysis of the cluster-based P2P protocol and derives the optimal cluster formation in MANET. In the derived optimal cluster formation, the cluster-based P2P protocol shows better performance than Gnutella protocol with respect to control traffic.

A nurse is give much weight in the professions of hospital.The effective achievement of a goal of hospital organization needs to get nurses to contribute the structure positively through the rational personnel management of the nurses.The operation of performance rating system is necessary to improve because the nurses hold negative opinions about the resonable management of that system in most Korean hospitals.Therefore, the prupose of this research was to suggest an efficient method to solve the problem in connection with the management of nurses performance rating system.The results of the study are summarized as follows.1. As the performance rating implies the evaluation of employee's functional accomplishment and ability, and essential condition of the job was surveyed according to the job analysis of nursing activities and nurse position.That is to say, Nusrses' performances and capability is estimated in comparision with the condition of the job. 2. It is required adequacy for evaluation factors in performance rating.That is, $\circled1$ as for those who work in psychiatry or newborn baby room they should be appraied in terms of different factors from those applicable to whom work in a general staffs. $\circled2$ Evaluation factors should be concrete so that the quality and quantity of work and the potential ability of them can be correctly appraised. 3. In order to realize the object of perfamance rating system, the training on chief nurses are quite important. Also, careful practices and continuous supplementary training are required before the system is introduced.First of all, the appropriate evaluation can be mad by continuing to record the rating objects every day for the purpose of obtaining the objectivity of rating. 4. In course of transfering of the position and training, the induction of self-rating system and presentation of self-description is required to supplement functionally the performance rating system. 5. For the efficiency of nurses' performance rating system, the results of performance rating system must be reflected in promotion, allocation and training course, which makes the nurses have the motives and the organization accomplish the goal of modern nursing through its activation.

This study was conducted to evaluate nutritional status of Korean women of child-bearing age. A comparison was made between 113 non-pregnant and 200 pregnant women. Pregnant women of 24-28 weeks of gestation were recruited from prenatal clinic in Seoul. Nonpregnant women were included college students, nurses, office employers, and sales women. General characteristics, anthropometric measurements, dietary intakes, and hematological values were assessed. There was no difference in mean BMI for nonpregnant and pregnant (pre-gravid) women, which were 20.2 kg/m$^2$and 20.6 kg/m$^2$respectively. The pregnant women showed a tendency of better health-caring behavior, evidenced by stop smoking and drinking, and in taking nutrient supplements. The mean intakes of energy, vitamin A, vitamin B$_2$, calcium, and iron did not meet Korean RDA for adult women. In particular, calcium and iron intakes of both nonpregnant and pregnant women were under 60% of the Korean RDA. Judging by MDA score, dietary quality was better in pregnant than in nonpregnant women. Mean serum values of albumin, total cholesterol, LDL-cholesterol, HDL-cholesterol, Hb, IgA, IgG were in normal range. However, more than 13% of the nonpregnant subjects showed mild hypercholesterolemia (cholesterol > 200 mg/dl) and anemia (Hb < 12.0 g/dl) . The percentage of anemia in pregnant women were much higher; the subject with Hb < 11.0 g/dl were approximately 30%. The pregnant subjects showed significantly higher serum concentrations of triglycerides and cholesterol, and significantly lower concentrations of albumin, IgA, and IgG compared to nonpregnant women. Correlation analysis showed that Hb concentrations were correlated with the intakes of iron- and protein- containing foods such as meat and vegetables. This study strongly suggest that iron-deficient anemia is a major nutrition problem in Korean child-bearing women and this condition is correlated with dietary intakes.

The government has the responsibility to prevent abuses of monopoly and promote competition in order to maximize consumer welfare. The government should address the asymmetry in the information as much as possible and ensure consumer choice. The subsidy seems to reduce the burden on the consumer service charges and handset prices but it actually distorts the market through price discrimination. The government caused the principal-agent problem by neglecting their appropriate role to prevent distortion of the mobile telecom market. The money used as subsidy is part of excess profit and could be transferred to down the price of mobile phone and charges and it would become a benefit to consumers. Separate announcement of subsidies by Mobile Communications Terminal Distribution Structure Improvement Act is a little developed policy but it was not actually realized. The market price close to that from perfect competition structure is plausible, ultimately.

The purpose of this study is to suggest a countermeasure against a major cause that leads to game addiction, by grasping tendency of the actual condition for the online game use in freshmen for university and by analyzing relationship of game addiction according to factors. As a result of analyzing on relationship among sub-variables for game addiction, it could be known that the more men in gender leads to the more serious game addiction and that the longer game time given using once leads to the higher level in control loss and game addiction. Also, it was indicated that the more in group with high risk leads to the more serious in physical and mental problem. There is a suggestion that a scale related to game is developed for the expansion in counseling institution nationwide and for the preventive education targeting all the ages including undergraduates and adults as well as small children and children.

In this paper, we propose a lunar landing scenario of a robotic lunar landing mission and implements an optimal landing trajectory at the powered descent phase based on the proposed scenario. The change of attitude of the lunar lander in the power descent phase affects not only the amount of fuel used but also sensor operation of image based navigation. Therefore, the attitude angular velocity is included in the cost function of the optimal control problem to minimize the unnecessary attitude change when the optimal landing trajectory generates at powered descent phase of the lunar landing. The influence of the change of attitude angular velocity on the optimal landing trajectory are analyzed by adjusting the weight of the attitude angular velocity. Based on the results, we suggest the proper weight to generate the optimal landing trajectory in order to minimize the influence of the attitude angular velocity.
