In order to facilitate the Korean government's efforts in integrating family planning and maternal & child health at the primary health care level (or township level), the Soon Chun Hyang College of Medicine, with the financial and technical assistance of WHO, has under-taken a service research project. The project has employed a quasi-experimental study design introducing interventions tat provide crucial factors lacking in the ongoing government programs such as midwives and qualified referral physicians. The study is being conducted in three locations, one control area and two study areas. Before introducing trained Nurse/Midewives into the study areas, a baseline prevalence survey was undertaken from 15 July 1981 to 10 August 1981 in selelcted townships of Seosan County. In this sample survey of bath the study and control areas, 2,484 eligible women (97% reponse rate) were interviewed to obtain benchmark data on basic evaluation indicators related to family planning and maternal and child health. The salients results were summarized as follows.: 1. CONTACT RATES WITH HEALTH WORKERS; During the year preceding the survey, 12% of women were visited by government health workers. The primary reason for such visits by health workers was family planning (45% of the visits). About 34% of the women visited the health centers during the year. The primary reason for visiting health centers was immunizations for their children (45% of the visits). 3. FAMILY PLANNING USE RATE; The baseline data showed little difference between women in the study area and the control area on contraceptive use. Approximately 59% were currently using some methods. However, among those current users, almost half were practicing less effective methods of birth control such as rhythm or withdrawal. Among other methods, the tubectomy was the most popular (16%), while use of the IUD, oral pill and condom together reached only 14%. 3. PRENATAL CARE RATE; About 75% of the women reported no prenatal care for their last births (the youngest child of each women), Additionally, among women received prenatal care, over half had only one visit. 4. ATTENDANCE AT DELIVERY; Most of the women surveyed (over 80%) were attended by a non-medical person during their last delivery. These figures are somewhat comparable to the national figure of 84% for remote areas. 5. POSTNATAL CARE; The proportion of women reporting postnatal care was only 4.5%, and postnatal care was not received by the majority of women surveyed. 6. CHILD HEALTH CARE: In contrast to the low rate of maternity care for women themselves, most women reported obtaining immunization care for their children. About 75% of the women obtained Polio and/or DPT, 58% BCG, and 44% Measles vaccine for their children. However, in terms of illness care, while 35% of the women stated that their youngest child had been sick during the month preceding the survey, only 28% of these women took their child to the clinic for treatment. 7. COMPLICATIONS OF PREGNANCY AND DELIVERY AND ABNORMALITIES IN THE NEWBORN; Among all last deliveries, 18% of the women had pregnancy complications and 9% of the women had complications during delivery About 5% of the women reported abnormality in their most recent newborn. 8. REPRODUCTION EFFICIENCY; PERINATAL MORTALITY AND INFANT MORTALITY Based on data from the pregnancy history in this survey, reproduction efficiency was estimated. Out of the 11,154 pregnancies reported by all women surveyed, foetal loss was 21% (almost 16% were induced abortions) and infant deaths before reaching one year old were 3.1%. The reproduction efficiency was, therefore, reduced to 76%. In terms of perinatal and infant mortality rates, the former was 40.2 per 1,000 total births and the latter was 39.3 per 1,000 live births. Both rates described J shaped relationships with age of mothers and parity, and they were also correlated with birth interval and mother's education. In summary, this baseline survey data indicated a need for (1) improving contraceptive practices with more effective methods to prevent unwanted pregnancies and (2) providing better services for maternal and child care to protect wanted pregancies. In the Korean rural setting. the author believes that the latter is more important as the value of each child has increased as a result of the family planning campaign for the past two decades. This calls for more effective integration of Family Planning and MCH programmes to meet the needs of the family in each stage of the child bearing and rearing period with deploying more qualified personnel than the current government program personnel.

With increased use of neurotoxic agents in manufacturing industries, hazardous effects of neurotoxic agents pose significant problems in protecting health of workers who work in these industries. A normal range of neurobehavioral performance is required to study hazardous effects of neurotoxic agents among workers. However, such reference for Korean population is not available yet. The objective of this study is to estimate a normal range of neurobehavioral test performance of female workers in Korea. Data for neurobehavioral test performance developed by the World Health Organization were obtained from 165 female workers. Study subjects, 140 production workers and 25 clerks, who voluntarily participated in this study were not occupationally exposed to neurotoxic agents. The mean age and the mean education years of them were 32 years and 10.9 years, respectively Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention tests among the Neurobehavioral Core Test Battery(NCTB) were included in the evaluation. Subjects were interviewed by a trained interviewer for their detailed occupational history $Mean({\pm}SD)$ performance of the participants were: $45.7{\pm}7.1\;and\;41.9{\pm}6.4$ in the Santa Ana dexterity test of the preferred and non-preferred hands; $45.7{\pm}7.1\;and\;41.9{\pm}6.4$ in correct dot of the pursuit aiming test; $57.7{\pm}16.0$ in the digit symbol test; $274.8{\pm}44.6$ msec in the mean simple reaction time and $70.5{\pm}69.0$ msec in the mean standard deviation of it; and $7.8{\pm}1.7$ in the Benton visual retention test. Most neurobehavioral performance scores were correlated significantly with age and educational level. Educational level was found to be a significant independent variable which was associated with all test scores. Age was significantly associated with scores of pursuit aiming and digit symbol tests.

Lately, in consumers' markets the number of new items is rapidly increasing at an overwhelming rate while consumers have limited access to information about those new products in making a sensible, well-informed purchase. Therefore, item providers and customers need a system which recommends right items to right customers. Also, whenever new items are released, for instance, the recommender system specializing in new items can help item providers locate and identify potential customers. Currently, new items are being added to an existing system without being specially noted to consumers, making it difficult for consumers to identify and evaluate new products introduced in the markets. Most of previous approaches for recommender systems have to rely on the usage history of customers. For new items, this content-based (CB) approach is simply not available for the system to recommend those new items to potential consumers. Although collaborative filtering (CF) approach is not directly applicable to solve the new item problem, it would be a good idea to use the basic principle of CF which identifies similar customers, i,e. neighbors, and recommend items to those customers who have liked the similar items in the past. This research aims to suggest a hybrid recommendation procedure based on the preference boundary of target customer. We suggest the hybrid recommendation procedure using the preference boundary in the feature space for recommending new items only. The basic principle is that if a new item belongs within the preference boundary of a target customer, then it is evaluated to be preferred by the customer. Customers' preferences and characteristics of items including new items are represented in a feature space, and the scope or boundary of the target customer's preference is extended to those of neighbors'. The new item recommendation procedure consists of three steps. The first step is analyzing the profile of items, which are represented as k-dimensional feature values. The second step is to determine the representative point of the target customer's preference boundary, the centroid, based on a personal information set. To determine the centroid of preference boundary of a target customer, three algorithms are developed in this research: one is using the centroid of a target customer only (TC), the other is using centroid of a (dummy) big target customer that is composed of a target customer and his/her neighbors (BC), and another is using centroids of a target customer and his/her neighbors (NC). The third step is to determine the range of the preference boundary, the radius. The suggested algorithm Is using the average distance (AD) between the centroid and all purchased items. We test whether the CF-based approach to determine the centroid of the preference boundary improves the recommendation quality or not. For this purpose, we develop two hybrid algorithms, BC and NC, which use neighbors when deciding centroid of the preference boundary. To test the validity of hybrid algorithms, BC and NC, we developed CB-algorithm, TC, which uses target customers only. We measured effectiveness scores of suggested algorithms and compared them through a series of experiments with a set of real mobile image transaction data. We spilt the period between 1st June 2004 and 31st July and the period between 1st August and 31st August 2004 as a training set and a test set, respectively. The training set Is used to make the preference boundary, and the test set is used to evaluate the performance of the suggested hybrid recommendation procedure. The main aim of this research Is to compare the hybrid recommendation algorithm with the CB algorithm. To evaluate the performance of each algorithm, we compare the purchased new item list in test period with the recommended item list which is recommended by suggested algorithms. So we employ the evaluation metric to hit the ratio for evaluating our algorithms. The hit ratio is defined as the ratio of the hit set size to the recommended set size. The hit set size means the number of success of recommendations in our experiment, and the test set size means the number of purchased items during the test period. Experimental test result shows the hit ratio of BC and NC is bigger than that of TC. This means using neighbors Is more effective to recommend new items. That is hybrid algorithm using CF is more effective when recommending to consumers new items than the algorithm using only CB. The reason of the smaller hit ratio of BC than that of NC is that BC is defined as a dummy or virtual customer who purchased all items of target customers' and neighbors'. That is centroid of BC often shifts from that of TC, so it tends to reflect skewed characters of target customer. So the recommendation algorithm using NC shows the best hit ratio, because NC has sufficient information about target customers and their neighbors without damaging the information about the target customers.

One of the subtle problems that make noise control difficult for engineers is “the invisibility of noise or sound.” The visual image of noise often helps to determine an appropriate means for noise control. There have been many attempts to fulfill this rather challenging objective. Theoretical or numerical means to visualize the sound field have been attempted and as a result, a great deal of progress has been accomplished, for example in the field of visualization of turbulent noise. However, most of the numerical methods are not quite ready to be applied practically to noise control issues. In the meantime, fast progress has made it possible instrumentally by using multiple microphones and fast signal processing systems, although these systems are not perfect but are useful. The state of the art system is recently available but still has many problematic issues : for example, how we can implement the visualized noise field. The constructed noise or sound picture always consists of bias and random errors, and consequently it is often difficult to determine the origin of the noise and the spatial shape of noise, as highlighted in the title. The first part of this paper introduces a brief history, which is associated with “sound visualization,” from Leonardo da Vinci's famous drawing on vortex street (Fig. 1) to modern acoustic holography and what has been accomplished by a line or surface array. The second part introduces the difficulties and the recent studies. These include de-Dopplerization and do-reverberation methods. The former is essential for visualizing a moving noise source, such as cars or trains. The latter relates to what produces noise in a room or closed space. Another mar issue associated this sound/noise visualization is whether or not Ivecan distinguish mutual dependence of noise in space : for example, we are asked to answer the question, “Can we see two birds singing or one bird with two beaks?"

Purpose : Since the acquired immune deficiency syndrome (AIDS) was first recognized in the United States in the summer of 1981, the number of these patients has been increasing in the world. But do not find out a cure and a vaccine for ARS (5). And so, the best treatment for AIDS is the prevention. People can find out accurate knowledge about AIDS, and they can prevent themselves from AIDS approximately 100%. In this study, we investigate with AIDS knowledge and attitudes in unmarried young men (<24 age) and suggest accurate preventive education for AIDS and good sexual behaviors. Methods : Un-married young soldiers and college students who were not diagnosed as AIDS until June 30, 2000 were included in the study. The study included a total of 923 men. A self evaluation questionnaire, included questions on 36 items(the part of demographic data - 9; the part of knowledge - 20; the part of attitudes - 8), was drawn up by three physicians. The demographic data, AIDS knowledge and attitudes were analyzed by chi-square analysis, and the total score of AIDS knowledge - comparison according to demographic factors and attitudewere analyzed by one-way ANOVA test. Results : In demographic characteristics, as for the first recognized time of AIDS, most of men knew it when they were in their middle school, as for sources of information on AIDS, most of them knew it through the TV-media, and as for the educational need about AIDS, most of them agreed with it. In AIDS knowledge, mean scores were $14.0{\pm}1.8$ (70.3%). Items of the misconceptions concerning AIDS, reported as less than 50% correct answers, were 6 among 20 items (30%). In AIDS attitudes, as for the item about that if I will be an AIDS patient, I will have an AIDS treatment, it showed that the number of men agreed with 759 (82.2%), and as for the item about that I will help for AIDS patient even though I don't know him, it showed that the number of them agreed with 412 (45.8%). In correlation of AIDS knowledge and demographic factors, the mean scores of knowledge of men with higher than college degree were higher than them of others. The mean scores of knowledge of men with total income of family with more than US$1667 were higher than them of others. The mean scores of knowledge of men with sources of information on AIDS through the TV-media were higher than them of others. And the mean scores of knowledge of men with past medical history of STD(sexually transmitted disease) were higher than them of others. Conclusions : The higher the knowledge he has, the lower the possibility of risk and the more positive the attitude he has. And then we think that the education program for AIDS will be included as a regular part of the curriculum in high school, and young men must be effectively educated by it.

King Munjong(文宗), the eleventh King of the Goryeo Dynasty, was the son of King Hyeonjong(顯宗), the eighth king, and the younger stepbrother(異母弟) of King Jeongjong(靖宗), the 10th king. Although King Jeongjong had four sons, he abdicated the throne to King Munjong. King Taejo(太祖) had opened the possibility for sons other than the eldest son to succeed to the throne. When King Jeongjong died, his sons were children under the age of 10 years. In the early period of the Goryeo Dynasty, when kings had young sons, there were precedents of abdicating the throne to their grown-up younger brothers. In addition, King Jeongjong and Munjong had an identical blood background. During the period, Goryeo people also naturally accepted the fact that a former king's younger brother succeeded to the throne. In this background, King Munjong ascended the throne. However, King Munjong did not ascend the throne after identifying state affairs with politic power. Therefore, he needed to increase his authority as the king. Moreover, as the sons of King Jeongjong had grown up, they could stir up trouble in future succession to the throne. Therefore, King Munjong intended to concentrate power on himself and remove trouble in future succession to the throne by selecting his son as successor to the throne. After the installation of Wangtaeja(王太子, the Crown Prince), King Munjong expanded and organized Donggunggwan(東宮官, the establishment of Secretariat of Wangtaeja) and carried out various rituals related to Wangtaeja. The control system for Donggunggwan was completed institutionally in 1068. At this time, the newly organized Donggunggwan was operated as a miniature version of the central government office. In addition, the ritual for the installation of Taeja, which was held in 1054, complied with regulated procedures. After the ritual of the installation, a ceremony to congratulate on Jangheungjeol(長興節, the birthday of Wangtaeja) was held in 1056. In 1064, the wedding ritual of Taeja took place, and the ritual for Taeja regulated in Yeji(禮志) of "Goryeosa(高麗史)" was carried out. In addition, the installation of Wangtaeja was made known overseas, and the Taeja of Goryeo was proclaimed by the Kitan three times. Such various measures played an important role in strengthening the status of Taeja as the man of authority next to the king. Later, Taeja demonstrated his status as the man of authority following the king by participating in state affairs on behalf of King Munjong who was not able to move about freely in his later years.

In the late Joseon Dynasty, patriarchal ideology became central to the family and the clan, and once again became acutely felt with "the familism of clan rules that centered around a legitimate and eldest son." The establishment of the family-clan system, though somewhat complex, was largely aimed at the family line of "a paternalist-a legitimate and eldest son." The trend was not limited to a particular family, but rather, was a historical and social trend. Changseonggameirok showed how to solve the family crisis by setting up a problem for the next generation's patriarch. This paper tries to explain the issue of Hwachun's complex as the legitimate and eldest son complex. First, it suggests that Hwachun's complex is as universal as the Cain complex, also known as the eldest son complex, and that Hwachun's complex is a special instance of the legitimate and eldest son complex in Changseonggameirok. Next this paper studies the aspects of Hwachun's legitimate and eldest son complex combined with Mrs. Sim's complex, as well as her daughter-in-law's complex, and eventually tracks the development of the family-clan complex. As a result, we've come to a new conclusion that the legitimate and eldest son complex was found in Changseonggameirok for the first time in Korean literary history. This paper also examines the fact that when the legitimate and eldest son complex was transferred to Hwajin, it became a family complex that Hwajin had to contend with; this paper tracks the process wherein Hwajin's filial piety solved the legitimate and eldest son complex. As a result, we realized that Hwajin's filial duty and brotherly love went beyond his feelings for Mrs. Sim and Hwachun, and supported the substantiation for "the familism of a clan that is based on rules of the legitimate and eldest son" in the course of public opinion. However the familism of these rules was not embodied in the absolute; in the royal family, for example, it was rather flexibly implemented when the characters admitted to breaking the law. In addition, this paper provides the room for a critical reading of Changseonggameirok, reflecting back on the underlying guilt and psychological pain of the characters who are affected by the particular rules, and concluding that guilt and suffering are fundamentally insoluble. This is because the two ideas, "the legitimate and eldest son complex" and "the familism of a clan rules centered on a legitimate and eldest son" are two sides of the same coin.

The purpose of this paper is to analyze the meaning of of "Nikolai Garin - Mikhailovsky's the "Joseon tale". talks about the origins of the Joseon Dynasty and the Qing Dynasty. In this paper, we revealed the features of the form of "Otter Legend". And analyzed the confrontation between Nurhachi's family and Yi Seong-gye's family shown in the story. The result is as follows. is complex tale. The start of is 'the typr of Yaraeja'. Next is the story of Myoung-Dang. Myoung-Dang is deep in the water. also has anecdotes of Jeong, Chung-shin. rearranged at least three stories or more. transformed each type of stories, communing the different patterns of stories with different logic. The basic logic of the transformation was to maximize the confrontation between the NuruhachI and Yi Seong-gye clans, the origins of Manchuria and the Chosun Dynasty. As a result, the sacredness of Nurhachi's Family, the origin of the Qing Dynasty, was expanded. On the other hand, Yi Seong-gye s Family was less extraordinary than Nurhachi's Family. Also, the ability of the person is also inferior. This is not the yearning for the Qing Dynasty. This is because the Qing Dynasty and the Joseon have the same pedigree. shows that the Qing Dynasty's experiences should be shared since the Qing Dynasty was born of another clan of Joseon. This is a new perception of Qing Dynasty. This is similar to the interpretation that dragged the Qing Dynasty's history into the Joseon's ethnographic historical point of view.

A lien is the right to possession the thing until receiving repayment of its bonds in some cases that the property of other person or the occupant for marketable securities receive the bond that has occurred on that property or marketable securities. This has own purpose to break 'principle of creditor equality' to protect especially the bond of the subject occupant in terms of justice. These lien on our civil law come according to the law in prepared certain requirements. However, an incomplete real rights granted by way of security that does not have a preferential performance right or seniority on the exchange value of the object suffer from the problems a lot in the real estate auction process because of the feature that is not announced in the register unlike the mortgage. In addition, the lien of real estate is not lapsed in an auction process. There is no preferential performance righ in a positive law as providing that can oppose to the buyer(a successful bidder) until received repayment the secured bond price to be compliant with the lien(Civil Case Execution Law the 91st clause of Article 5). However, as asserted the super preferential performance righ to a buyer in real terms, acts as primary cause of breaking unexpected loss and according unfair law relation to a senior mortgagee and seizor, etc. and the principles of the creditors equality to the persons concerned in other words, the principles of justice. All of these issues are the establishment of the lien and theory conflict on the effects. In spite of the fluctuations of a real right about real estate is announced as a registration by the current law, only the lien come into unclear announcement means for possession. In addition, Civil Case Execution Law argument is caused by the adoption abernahmeprinzip about the lien (Civil Case Execution Law the 91st clause of Article 5). Therefore, this paper was examined briefly the significance and purpose, history and law-making examples of each country and the valid requirements and effect of the lien that is basic principle of law about the lien system above all. And then, it will be reviewed the improvement plan for de lege ferenda to improve the issues about this after reviewing the objection, theory and judicial precedent about opposing power and preferential performance right of the lien in the real estaKey Words : Lien, Oppose Power, Mortgage right, Preferential Performance right, Seizure, Real Estate Auction, Lien who can not Opposing against Successful Bidder, Lien who can Oppose against Successful Bidder, Possessionte auction that is a fundamental problem on requirement and effect of the lien.

The purpose of this study is to illustrate the history of the Cheonsu-Temple天壽寺 and to describe the echo verse poem trend with regard to 'Waiting'待人 and why it is beautiful. The Cheonsu-Temple was located in the outskirts of Gaesung開城, the capital city during the Corea高麗 Dynasty. However, the temple was destroyed when the dynasty collapsed. Cheonsu-Station天壽院 was built amidst the temple ruins, as the temple was an important traffic point. The Cheonsu-Pavilion天水亭 was built in 1476 by Yi-Ye李芮 in the station's neighborhood. The station and the pavilion were completely ruined during the 17th century. Many poets visited the Cheonsu-Temple and composed poems in the latter part of the Corea Dynasty. 'Waiting'待人, written by Choi-Sarip崔斯立, -is the most famous work. Following this work, many poets composed echo verse poems 'Waiting' work that represented the anxiety of waiting for an old friend in front of the Cheonsu-Temple. The following is a highlighted verse: So many people who look like the old friend come to me, but it turned out no one was the man. This work is very picturesque. Over twenty echo verse poems 'Waiting' are categorized in three periods. They compared the "present" to the past by using the Zhenglingwei丁令威 origin from the former Joseon朝鮮 period. In the middle of Joseon period, Jungjong中宗 visited Cheonsu-Station and composed an echo verse poem 'Waiting'. The official literaries also composed poems there. In their works, they presented the collapse of the Corea Dynasty as inevitable and the construction of Joseon Dynasty as something reasonable. Cheonsu-Station was ruined in 17th century, followed after by the ruin of the Cheonsu-Pavilion. It appears that the echo verse poems to 'Waiting' in the latter Joseon period represented the ruin of the Cheonsu-Temple, the Cheonsu-Station, and the Cheonsu-Pavilion.
