The goal of the present study is reviewing the literature on the scientific community and also on science, technology & society to increase interactions between innovation studies and social studies of science and technology. Up until now, various empirical studies on Korean scientists and engineers have been concentrated on researchers at universities, while they have paid inadequate attention to researchers at state-funded research institutes and private companies. In addition, these studies have tended to use concepts in Western academia to elucidate Korean cases. On the other hand, recent empirical researches on the effects of the evaluation systems in universities, PBS system, and the network of school ties suggest that these topics may reveal the unique characteristics of Korean scientific community. Empirical studies on the scientific community have also shown that Korean research institutes and researchers who are in charge of innovation in Korea have demonstrated a tendency to conform to the government's guidance due to long experiences of state-led R&D and nationalism. Research on science, technology and society has viewed the participation of citizens in science and technology as a way toward science and technology democracy, and tended to have a strong practical orientation. However, there has been a relatively small amount of research on how citizen participation influences the direction and content of technological innovation. Also, although, from the viewpoint of technological innovation, how participation of citizens in science and technology can contribute to knowledge production and innovation is a critical issue, relatively small numbers of case studies on this subject have been conducted. Therefore, as the scholars who have emphasized the democracy of science and technology have actually experimented with various ways of citizen participation, innovation researchers may have to design and implement citizen participation through which citizens' local knowledge can contribute to technological innovation.

Rough rice samples of four rice varieties were collected from twenty five locations through the country just after 1986 rice growing season. Various characteristics related to rice grain quality were observed to clarify the degree of locational variation of physico-chemical properties, and cooking and eating quality of rice grains. Grain weight, grain shape, degree of translucency and chalkiness of rice grain, amylogram properties of rice flour, water uptake during cooking, and cooked rice appearance were different between varieties tested. High degree of locational variation were found in following characteristics, degree of translucency and chalkiness of rice grain, water uptake during cooking, cooked rice appearance and amylogram properties. Eating quality of cooked rice indicated by sensory score showed different tendency of locational variation between rice varie-ties tested, and locations produced rice grains showing better eating quality were not coinside with among varieties tested. Grain weight, degree of translucency and chalkiness of rice grain, and cooked rice appearance of rice samples showing better eating quality were quite different to rice grains showing poor eating quality. Rice having better eating quality of a japonica variety, Chucheong, showed higher value of peak and final viscosity, viscosity after cooling, consistency and set back on amylograph compared with those of poor eating quality rices, and break down value of better rice was lower than that of poor rice. However, a Tongil type variety, Taebaek, did not show any consistent difference between better and poor rices. Rice samples from six locations in Chucheong and four locations in Taebaek showed special properties on amylogram compared with other rices collected in this study.

The Design Society of Korea. It is our urgent task that we should map out our detailed guiedlines for the improvement of export-oriented industries and of the design of export goods in preparation for our export goal of $30 billion in the upcoming 1980s. The government, university design researchers, and most entrepreneurs have confronted diverse kinds of racking issues: how much do most export industries take advantage of the indus-trial design for the improvement of the quality of export goods\ulcorner, structural defects of most export industries, chronic and vicious cycle of overlooking the value of the industrial design in the process of manufacturing export goods and etc. In other words, the recent trend of slighting the industrial design is to speed up the sales of only unsophisticated goods on the international markets. Although Koreans have been plagued by scantiness of natural resources under these circumstances, most Korean people have showed off their strong will for today's growth. Furthermore, most exporters should do their best to sweep overseas markets by manufacturing sophisticated goods outranking those commodi-ties made by the United States, Japan, West Germany and the other developed countries. In this respect, we have to make our best efforts for the expensive application and practical use of the industrial design, one of the comprehensive sciences, in the face of the hard realities and conditions which we have confronted until now. For example, it can be attributed to the practical application of the industrial design that the neighboring Japan, West Germany, France, the United Kingdom in Europe, and the United States in North America have formulated a highly advan-ced cultural zone and braced up for their own trade protection-ism and tightened their embargoes on EEC goods. Unless any export goods take the best advantage of the industrial design, one of the behavioral sciences capable of satisfying the material mental needs of modern men and of promoting cultural growth, I am convinced that they will not infiltrate into any countries that have enjoyed their own highly cultural lives. It is absolutely important that most Korean universities, state-run, private corporations and research institutes should work out the improvement strategy for the development and practical use of the industrial design as will as the revision of the present curricula of the departments of design. However, most design researchers have come to grips with several difficult problems such as the correlation of export oriented industries and the industrial design and the development of the design of export goods. The improvement of the industrial design is our urgent assignment that we have to solve in the 1980s. Accordimgly, I cannot too much emphasize the value the recognition of the industrial design in our industrial communities because we have never witnessed the prosperity of those countries which have taken little notice of the importance of the industrial design. Hopefully, most entrepreneurs will take much consideration of the value of the industrial design and then can defeat their rival businessmen on the international markets by exporting goods of highly sophisticated design. In this respect, the main purpose of the research paper which this society presented is to underline the fact that the improvement and development of the industrial design is our common assignment to be studied from the viewpoints of national dimension as well as in conformity with our immediate goal for the export-oriented prosperity of state. In conclusion, I would like to highlight the fact that our export goods shall be continually developed in pace with the correlative improvement of the indudtrial design so as to pave the way for their bright prospect and to enhance their best impression of the first-class goods on the international markets.

If we are to define that the traditional costume is a comprehensive expression of the culture, thoughts, and arts of a country, it is needless to say that the traditional costume would have always reflected the social and cultural aspects of the times. In order words, the cultural contemplation of a certain people at some point the history is only possible when we observe the distintive features of the costume worn by the people of respective times. Although the Korean people had the native costume of its own from the times of the Ancient Choson to the Three Kingdoms of Koguryo, Paekche, and Silla, the Chinese influence on Korean traditional costume became somewhat pronounced ever since the Silla strenghtened the political ties with the T'ang dynasty in China, and it came to a climax when the dual structure in Korean native costume, being compounded with the Chinese touch, continued to be prevailed from the era of the Unified Silla to the Koryo and throughout the succeeding Yi dynasty, thereby copying the typical aspects of Chinese pattern in clothing and dresses worn by the ruling classes, namely the goverment officials including the Kings. Therefore, it is our aim to study the pattern of Chinese influence on our traditional costume, as well as social and cultural aspects by way of contrasting and comparing our official outfit system, which had been developing in dualism since the era of the Unified Silla, with that of China, and to trace in part the Korean traditional costume. In comparing our traditional official outfit system with that of China, we have basically concentrated on the comparison of the official outfit systems during the periods of the Three Kingdoms, the Koryo, and The Yi dynasty with that of corresponding era of Chinese history, namely the dynasties of T'ang, Sung, and Ming, and followed the documentary records for the comparison. Koreans had fallen into the practice of worshipping the powerful in China and begun to adopt the culture and institutions of the T'ang dynasty since the founding of the Unified Silla. From this time forth, Korean people started to wear the clothes in Chinese style. The style of clothing during the period of the Koryo Kingdom was deeply influenced by that of the T'ang and Sung dynasties in China, and it was also under the influenced of the Yuan dynasty(dynasty established by the Mongols) at one time, because of the Koryo's subordinative position to the Yuan. At the close of the Koryo dynasty, the King Kongmin ordered the stoppage on the use of 'Ji-Joung', the name of an era for the Yuan dynasty, in May of the eighteenth year of his rule in order to have the royal authority recognized by a newly rising power dominating the Chinese continent, the Mind. Kind Kongmin presented a memorial, repaying a kindness to the Emperor T'aejo of the Ming dynasty in celebration of his enthronement and requested that the emperor choose an official outfit, thereby the Chinese influence being converted to that of the Ming. As a matter of course, the Chinese influence deepened all the more during the era of the Yi dynasty coupled with the forces of the toadyic ideology of worshipping the China, dominant current of the times, and the entire costume, from the imperial crown and robe to the official outfit system of government officials, such as official uniforms, ordinary clothes, sacrificial robes, and court dresses followed the Chinese style in their design. Koreans did not have the opportunity of developing the official outfit system on its own and they just wore the official outfit designated on separate occasions by the emperors of China, whenever the changes in dynasty occurred in the continent. Especially, the Chinese influence had greatly affected in leading our consciousness on the traditional costume to the consciousness of the class and authority. Judging from the results, Koreans had been attaching weight to the formulation of the traditional outfit system for the ruling classes in all respective times of the history and the formulation of the system was nothing more than the simple following of the Chinese system.

The paper investigates the possible relationship between earnings prediction by security analysts and special ownership ties that link security companies those analysts belong to and firms under analysis. "Security analysts" are known best for their role as information producers in stock markets where imperfect information is prevalent and transaction costs are high. In such a market, changes in the fundamental value of a company are not spontaneously reflected in the stock price, and the security analysts actively produce and distribute the relevant information crucial for the price mechanism to operate efficiently. Therefore, securing the fairness and accuracy of information they provide is very important for efficiencyof resource allocation as well as protection of investors who are excluded from the special relationship. Evidence of systematic distortion of information by the special tie naturally calls for regulatory intervention, if found. However, one cannot presuppose the existence of distorted information based on the common ownership between the appraiser and the appraisee. Reputation effect is especially cherished by security firms and among analysts as indispensable intangible asset in the industry, and the incentive to maintain good reputation by providing accurate earnings prediction may overweigh the incentive to offer favorable rating or stock recommendation for the firms that are affiliated by common ownership. This study shares the theme of existing literature concerning the effect of conflict of interests on the accuracy of analyst's predictions. This study, however, focuses on the potential conflict of interest situation that may originate from the Korea-specific ownership structure of large conglomerates. Utilizing an extensive database of analysts' reports provided by WiseFn(R) in Korea, we perform empirical analysis of potential relationship between earnings prediction and common ownership. We first analyzed the prediction bias index which tells how optimistic or friendly the analyst's prediction is compared to the realized earnings. It is shown that there exists no statistically significant relationship between the prediction bias and common ownership. This is a rather surprising result since it is observed that the frequency of positive prediction bias is higher with such ownership tie. Next, we analyzed the prediction accuracy index which shows how accurate the analyst's prediction is compared to the realized earnings regardless of its sign. It is also concluded that there is no significant association between the accuracy ofearnings prediction and special relationship. We interpret the results implying that market discipline based on reputation effect is working in Korean stock market in the sense that security companies do not seem to be influenced by an incentive to offer distorted information on affiliated firms. While many of the existing studies confirm the relationship between the ability of the analystand the accuracy of the analyst's prediction, these factors cannot be controlled in the above analysis due to the lack of relevant data. As an indirect way to examine the possibility that such relationship might have distorted the result, we perform an additional but identical analysis based on a sub-sample consisting only of reports by best analysts. The result also confirms the earlier conclusion that the common ownership structure does not affect the accuracy and bias of earnings prediction by the analyst.

The purpose of this study is to examine the actual cases of crane breeding at private homes in the Joseon Dynasty period, thereby identifying the universal meaning and characteristics of this act reflected in these cases. This study is likely to help understand the true nature of garden culture during the period. The study' temporal and spatial scope was limited to the Joseon Dynasty and private homes. As references for the study, translated versions of classical literature were selected from the Database of Korean Classics(http://db.itkc.or.kr). To complement for the data, related researchers' translated materials were also used in part. The study's results are summed up as follows: First, Individuals from various social classes including royal families, noblemen, noble families in countryside, and commoners kept cranes at their homes. These crane breeders included those who left a significant mark in the Joseon Dynasty politically and academically as well as 'cheosa(處士)' that refers to scholars living in seclusion without entering the government throughout their lifetime. Second, Crane breeders were spread all over the country. Notably, various cases of crane breeding were found within the Hanyang Wall and its vicinity. Third, The act of crane breeding was highly associated with blood ties and academic lineages such as friendships and teacher-student relations. In this regard, crane breeding was not just a simple taste or appreciation for the arts, but rather reflective of a person's life attitude and orientation. Forth, The consciousness of Confucian origins based on an ancient story of Limpo (林逋) appears to have a large impact on the act of crane breeding. In addition, some cases exhibited the reflection of Taoistic tastes. Fifth, Some individuals tamed cranes for a living. This proves the presence of steady demand for cranes in this period. The present study's limitation is its reliance on translated materials, which hindered research into various cases. Therefore, the future discovery of additional data and the accumulation of their translations will enable the investigation of a wealth of cases.

As broadcasting and communication are converged recently, communication is jointed to TV. TV viewing has brought about many changes. The IPTV (Internet Protocol Television) provides information service, movie contents, broadcast, etc. through internet with live programs + VOD (Video on demand) jointed. Using communication network, it becomes an issue of new business. In addition, new technical issues have been created by imaging technology for the service, networking technology without video cuts, security technologies to protect copyright, etc. Through this IPTV network, users can watch their desired programs when they want. However, IPTV has difficulties in search approach, menu approach, or finding programs. Menu approach spends a lot of time in approaching programs desired. Search approach can't be found when title, genre, name of actors, etc. are not known. In addition, inserting letters through remote control have problems. However, the bigger problem is that many times users are not usually ware of the services they use. Thus, to resolve difficulties when selecting VOD service in IPTV, a personalized service is recommended, which enhance users' satisfaction and use your time, efficiently. This paper provides appropriate programs which are fit to individuals not to save time in order to solve IPTV's shortcomings through filtering and recommendation-related system. The proposed recommendation system collects TV program information, the user's preferred program genres and detailed genre, channel, watching program, and information on viewing time based on individual records of watching IPTV. To look for these kinds of similarities, similarities can be compared by using ontology for TV programs. The reason to use these is because the distance of program can be measured by the similarity comparison. TV program ontology we are using is one extracted from TV-Anytime metadata which represents semantic nature. Also, ontology expresses the contents and features in figures. Through world net, vocabulary similarity is determined. All the words described on the programs are expanded into upper and lower classes for word similarity decision. The average of described key words was measured. The criterion of distance calculated ties similar programs through K-medoids dividing method. K-medoids dividing method is a dividing way to divide classified groups into ones with similar characteristics. This K-medoids method sets K-unit representative objects. Here, distance from representative object sets temporary distance and colonize it. Through algorithm, when the initial n-unit objects are tried to be divided into K-units. The optimal object must be found through repeated trials after selecting representative object temporarily. Through this course, similar programs must be colonized. Selecting programs through group analysis, weight should be given to the recommendation. The way to provide weight with recommendation is as the follows. When each group recommends programs, similar programs near representative objects will be recommended to users. The formula to calculate the distance is same as measure similar distance. It will be a basic figure which determines the rankings of recommended programs. Weight is used to calculate the number of watching lists. As the more programs are, the higher weight will be loaded. This is defined as cluster weight. Through this, sub-TV programs which are representative of the groups must be selected. The final TV programs ranks must be determined. However, the group-representative TV programs include errors. Therefore, weights must be added to TV program viewing preference. They must determine the finalranks.Based on this, our customers prefer proposed to recommend contents. So, based on the proposed method this paper suggested, experiment was carried out in controlled environment. Through experiment, the superiority of the proposed method is shown, compared to existing ways.

In August 1837, a list of wedding gifts was given by Queen Sunwon (1789-1857) to her son-in-law, Namnyeong-wie, Yun Eui-Seon (1823-1887) at the wedding of Princess Deok-on (1822-1844). This Honsubalgi is now kept at the National Hangeul Museum. This text was used in the present study to examine the everyday clothes of the royal son-in-law in the early 19th century. First, the everyday clothes were organized into about 36 types. They were classified as tops, bottoms, hats, accessories, belts, pouches, fans and shoes. Second, the most important clothes were the ordinary formal attire, composed of the namgwangsa dopo and namgwangcho changui. As for the bottoms, the pants, the Chinese hemp leggings, two pairs of socks, the green silk belt, and a pair of light blue ankle ties were identified. Third, as for the head and accessories, there were heukrip, with the gemstone string and silk string, the jeong-ja-gwan and dong-pa-gwan, as well as tang-geon and bok-geon. And there were the sangtu-gwan, three types of donggos, and the mang-geon equipped with okgwanja. On the other hand, the jeong-ja-gwan and dong-pa-gwan are peculiar hats whose status has changed over time since the mid-18th century. The fact that the jeong-ja-gwan and dong-pa-gwan were given to Namnyeong-wie showed that the status of these hats improved in the early reign of King Heonjong. The belt was given with the sejodae that is suitable for the dangsang, the coral plates, and the silk bag containing a flint pouch. Fourth, there were the red-colored sejodae, a ssamji silk pouch for flint and the fan decorated with okseonchu, and shoes, such as unhye and danghye.

Biotope, which represents the characteristic habitats of living organisms, need to be identified as essential for the efficient creation and sustainable management of urban ecosystems. This study was carried out to provide the basic information for ecological urban planning by analyzing types and attributes of the biotop established throughout the whole area of the Pohang city, a representative industrial city in Korea. The biotop established in Pohang city is composed of 12 types including forests (coniferous, deciduous, and mixed forests), agricultural fields (rice paddy and upland field), green facilities, river, reservoir, bare ground, residential area, public facilities, commercial area, industrial area, roads, and schools. As a result of analyzing the properties according to biotop types, industrial, commercial and residential areas, which represent urban areas, was dominated by introduced vegetation. Moreover the introduced vegetation is usually composed of exotic plants or modified forms for landscape architecture and horticulture rather than native plants, which reflects ecological property of both region and site. As the distance from the urban center increases, the agricultural field showed a form of typical farmland, whereas the closer it is, the more form of greenhouse farming. Natural green spaces were divided into riparian vegetation established along the stream and forest vegetation. Forest vegetation is consisted of secondary forests (seven communities) and plantations (three communities). The urban landscape of Pohang city is dominated by the industrial area. Among them, the steel industry, which occurs large amounts of heat pollution and carbon dioxide, occupies a large proportion. On the other hand, green space is very insufficient in quantity and inferior in quality. This study proposed several restoration plans and further, a green network, which ties the existing green spaces and the green space to be restored as a strategy to improve the environmental quality in this area.

This paper was triggered by the idea that the culture of ancestral rites and the patrilocality, which entail the excessive sacrifice on the part of the wife, that eventually led to the coinage of the expression, "housewives' holiday stress," is perhaps not the age-old traditions it claim to be, but rather a recent phenomenon. The purpose of this paper is to reveal that the loss of housewife's authority is the product of "becoming yangban (aristocrats)," which was a culture that was in fashion in the late Joseon dynasty. Until the late Joseon dynasty, women, in particular, the married women maintained an autonomous life which allowed them the authority to an extent, based on their properties that they brought from and the ties that they maintained with their original family and. However, such authority of the housewives disappeared since the invasion of Joseon by Japan and Qing in the year of Imjin (1592) and Byeongja (1636), respectively, as the daughters were excluded from receiving inheritance in a desperate attempt to maintain the impoverished family after the wars. However, patriarchy based on neo-Confucian custom and convention of patriarchal clan system could not spread to the entire population immediately after the wars, as it was impossible to include everyone in the aristocratic class (yangban). It was due to the increase of aristocrats within the continued social changes that occurred after the wars that the neo-Confucian patriarchy became the norm and ethical standard in Joseon society. Also, the theory of propriety in neo-Confucianism that everyone from the emperor down to commoners must abide by the patriarchal clan system was realized through Zhuzi jiali, i.e. Master Zhu's Family Rituals, which institutionalized the system of family rites by setting up ancestral shrines in every household. For the aristocrats who lost their financial footing, the only basis they could rely on to prove their aristocratic lineage is the strict compliance with the rituals. Also, for the once commoners who turned into aristocrats one day had to emphasize the formal propriety in order to distinguish themselves from the commoners. Hence, the culture of "becoming yangban" in the nineteenth-century Joseon was what solidified the patriarchal rituals, decorum, and clan system. As a result, women have become subordinated to the husband's families, which forced the women, i.e. the housewives to serve them and sacrifice themselves for them. At times, women self-imposed such restraints on them as they led themselves into believing that it was necessary to maintain the family for their sons.
