Laver is sea weeds that might have been eaten by Korean people since ancient times. The begining of laver culture is not known exactly, but it appears to be prehistoric age. Some laver culture complexes have been built in southern coastal sea of Korea around 1910. This paper was considered about the origin and development process of Korean laver culture industry by investigating Korean and Asian old books concerned. The results are as follows. 1. According to the Korean old books ralated, the name of laver is classified into 10kinds. Gim and Hae-I were called by Korean. Gim means weeds and Hae-I means the manufactured laver by cutting and drying like paper sheet. Ja-Chae and Hae-Tae are come from Chinese, however they are commonly called by Korean, Japanese and Chinese. Rest six names are come from Chinese botany. 2. As Chinese used laver as medicine for wen, scrofula, fever, vomiting, diarrhoea and. so on, they didn't regard it as foods and took into account an warning by Chinese botany that they could take ill when overeating it. On the other as Korean people have eaten it with pleasure nevertheless the Chinese warning, various foods using laver have been developed. The typical food is rice covering laver sheet. It is also popular to Japanese. 3. Laver culture can be carried out in all coastal seas around Korean peninsula, the best sea area for it is the middle west of south sea. 4. Seopkkoji type is a laver culture method that when branches of tree are put in tidal flat laver sporules are attached and gronm on them. It was begun by Hae-Jak Kun(a group of fishery slaves) on Kwang-Yang bay the most suitable for. laver growth at the beginning of King $Sung-long(1469{\~}1481)$. It is assumed that when Hae-Jak Kun set Oe-Jeon(a sort of fixing fishing gear) to catch tributary fish for king, they could find grown laver attached on Oe-Jeon and invent Seopkkoji type for exclusive laver culture. That was carried out 200 fears earlier than in Japan. Dde-Bal type is more advanced and productive laver culture method with thinly spilt bamboo tied like screen(one end fixed on bottom and other end set free in water), It is assumed that Dde-Bal type was begun in Wan-Do county in King Chull-Jong(1830). All laver culture methods developed were transfered to Japan.

Recently the rapid changes of the social environment make both university and every each department should have to renovate and adjust all of the educational components. The most dominant and issuable change of business administration education is the Business Education Accreditation which was certified by the KABEA(Korean Association of Business Education Accreditation). And the only two department of fisheries business administration which in Gyeongsang National University and Pukyong National University has been accredited recently. Though The department of fisheries business administration in Korea has been influenced by that Accreditation, there is few research and analysis on educational change. So it is very important that research on the curricular constitution and change of the curriculum for considering the its own effect and influence. This paper aims to explore the curricular constitution, change and course fulfillment of fisheries business administration after the business education accreditation based on the case of the department of fisheries business administration in Gyeongsang National University. The analysis of fisheries business administration change will help develop sustainable curriculum and give more guideline for identifying the core of fisheries business administration. The method of analysing that in this research has adopt the social network analysis(SNA) and automated software tool which is the most dominant technique in contents analysis including the Krkwics and Pajek. The SNA is evaluated that most popular, rigorous and firm methodology for analyzing, examining and revising some concepts or objects in the context of semantics. The result of this study shows that the ratio of fisheries business administration class has been decreased but still the most fulfilled course. And English mediated class has been avoided though that sort of the class has been increased. In the view point of course fulfillment, it has been potential and inefficient problems that some classes that including financial related and accounting related class would not been accomplished appropriately. The findings of a graduate depth interview which has been done about 4 years for understanding that student show that there's some recognition gap of fisheries business administration in staffs of human resource management. And the level of job satisfaction in fisheries business still somewhat low and even worse the chance of recruitment also unsteady.

This article presents a historical account of media role in the transition and consolidation period of democracy. Despite the assumption that media plays a important role in the construction of democracy, it is less clear how the media can affect the process of political change itself. This article seeks to answer some of these question, based on the Mill's macro-social comparative 'method of difference' of Korea and Spain. It is widely agreed that both states achieve democracy through transaction from above(pacts). Media role, however, differs significantly in accordance with authoritarian legacies and civic representativeness of the pacts. Whereas Korean dailies is deepening given market oligopoly and prior practices after democratization, Spain dailies market entirely changed in both structural and spiritual respects. As a result, Korean dailies substantially lacks in civic representativeness as before, contrary to Spain. Spain television settled a sort of the external pluralism. Korean television is pursuing the BBC type of internal pluralism. In Korea, television is more commercial than Spain. Consequently, Spain media serve the consolidation of democracy more than Korea on the whole.

The purpose of this study is to analyze the influence of digital textbook use for potential risk group of internet addiction and average group. For this, I selected two samples. One was a group to use digital textbook at school, the other was a group not to use that. Then each potential risk group of internet addiction were sort out in two groups by a test of internet addiction. I firstly compared a average user group and a potential risk group of internet addiction in group to use digital textbook. Also, I too did that in group not to use digital textbook. Then I analyzed the relevance of using digital textbook and internet addiction. As a result, I found that using digital textbook have not the relevance with internet addiction. But in this paper, I proposed a way to teach ICT ethical training before students use the digital textbook, because most of potential risk students of internet addiction tend to think they was influenced by digital textbook.

This study carried out first a component survey on the domestic waste shipped into a waste disposal facility in B city, and then heavy metal analysis of each component according to the SRF standards. Based on this, this study explored the problems with domestic waste and measures to improve them. The results are as follows. The result of the survey of physical components show that paper accounted for the largest proportion with 20.5 %~59.9 %, metals (including batteries) among incombustibles accounted for 0.0~8.3 %, other inorganic substances, glass and ceramics accounted for 0.0~43.7 % and 0.0 %~19.6 % respectively. However, the proportion of coated viny and plastics, which have high lead and cadmium content, was rather high with 2.9 %~30.9 %. This suggests the possibility that actual concentration of lead and cadmium within SRF is likely to be higher. Among the 15 components contained in the waste brought into the waste disposal facility, 10 components (food waste, textiles, vinyl, plastics, wood, rubber and leather, paper, metals, electronic substrates, and nail polish) were analyzed according to assay samples (approximately 0.1 g and 0.3 g). The result of analysis shows that the amount of Cd and Pb detected in coated vinyl for 0.109 g of assay sample was 98.6 mg/kg and 20.6 mg/kg respectively; 117.0 mg/kg and 29.0 mg/kg respectively for 0.313 g of assay sample. This is high contents exceeding the Cd standard. As for wooden component, the amount of Pb was 480.0 mg/kg for 0.3 g of assay sample. This suggests that there always exists the possibility of exceeding the exposure level of heavy metals (Cd and Pb) in SRF as long as coated wood and vinyl plastics with high contents of Pb and Cd are shipped into the waste disposal facility; and the local government and the residents need to work hard to improve the situation including development of the machine to sort electronic substrates and batteries for separate collection of the waste of coated vinyl and plastics within domestic waste.

The objective of this study were to examine the consumption pattern and awareness of Kimchi, which is our traditional food, preference for Kimchi, and the way of quality improvement in order to understand the recognition about the position and importance of Kimchi. The results are as follows. As for the recognition about regional way of making Kimchi, it turned out that married women in Seoul and Daejeon don't know their own ways of making Kimchi, and those in Daejeon don't know it more than those in Seoul. The rate of using Kimchi made at home was higher in Daejeon than in Seoul, and the rate of using Kimchi in both ways turned out higher in Seoul than in Daejeon. The reason why they use home-made Kimchi was that they generally prefer their own specific tastes both in Seoul and in Daejeon. Daily Kimchi ingestion was higher in Daejeon than in Seoul. Besides, the recognition about the superiority of our traditional Kimchi turned out high both in Seoul and in Daejeon. The survey of preferring Kimchi taste has been found that well pickled and proper seasoned Kimchi were most preferred both in Seoul and in Daejeon. Preference rate of various kinds of Kimchi came in the following order: Baechu Kimchi, Mu Kimchi, Oisobaki, Pa-buchu Kimchi in the Seoul area while Baechu Kimchi, Mu Kimchi, Pa-buchu kimchi, Oisobaki in the Daejeon area. In general, a sort of Kimchi stew was most popular as a dish using Kimchi with 63.8% both in Seoul and in Daejeon. It has been found in Seoul as well as in Daejeon that Kimchi served at a restaurant was usually untasty in comparison with Kimchi at home. The rate of preferring Kimchi on the markets in Seoul and in Daejeon as a whole came in the following order: Baechu Kimchi, Chongkak Kimchi, Baek kimchi People thought both in Seoul and in Daejeon that materials and cleanness were top priority when choosing Kimchi on the market. According to the result as above, recognition rate of Kimchi in the Seoul and Daejeon areas was shown rather low. Consequently, a further detailed research on Kimchi is thought to be needed. As the recognition of Kimchi increases, Kimchi consumption will increase accordingly. In order to prevent adult diseases, I think we should increase the consumption of Korean traditional fermentation food including Kimchi by increasing recognition of importance of nutrition, function, superiority, and the role of fermentation of Kimchi.

Social workers' behaviors in their organizations are governed not only by explicit rules but by implicit rules. This study aimed to measure the extent that the implicit rules exist in social work agencies, and to assess the impact of the implicit rules on the degree of social workers' devotion, burnout, and satisfaction in their own work places. This study also endeavored to search any sort of sanctions that agencies apply against workers who refused to follow implicit rules in their organizations, along with any harms and/or benefits which organizations may experience according to the extent that the implicit rules exist. The results showed that the implicit rules do not exist so much in social work agencies in Korea. Not so many sanctions in the organizations were not found against workers who violated the implicit rules. The amount of implicit rules, however, affected the degree of damages that organizations sustained. The more implicit rules exist in the organizations, the higher was the level of social workers' devotion, burnout, and dissatisfaction in the work places. The impact of implicit rules was powerful in a few areas of work. That is, social workers were required to do whatever things at hand rather than carrying out professional tasks only. Social workers were also asked to stay way beyond the closing hour. The explicit rules were dominant in the area concerned with social work ethics. Some strategies to substantiate social work practice were suggested on the basis of careful examination of the powerful implicit rules.

Background: The survival of non-small cell lung cancer (NSCLC) patients with brain metastases is reported to be 3~6 months even with aggressive treatment. Some patients have very short survival after aggressive treatment and reliable prognostic scoring systems for patients with cancer have a strong correlation with outcome, often supporting decision making and treatment recommendations. Methods: A total of one hundred twenty two NSCLC patients with brain metastases who received gamma knife radiosurgery (GKRS) were analyzed. Survival analysis was calculated in all patients for thirteen available prognostic factors and four prognostic scoring systems: score index for radiosurgery (SIR), recursive partitioning analysis (RPA), graded prognostic assessment (GPA), and basic score for brain metastases (BSBM). Results: Age, Karnofsky performance status, largest brain lesion volume, systemic chemotherapy, primary tumor control, and medication of epidermal growth factor receptor tyrosine kinase inhibitor were statistically independent prognostic factors for survival. A multivariate model of SIR and RPA identified significant differences between each group of scores. We found that three-tiered indices such as SIR and RPA are more useful than four-tiered scoring systems (GPA and BSBM). Conclusion: There is little value of RPA class III (most unfavorable group) for the same results of 6-month and 1-year survival rate. Thus, SIR is the most useful index to sort out patients with poorer prognosis. Further prospective trials should be performed to develop a new molecular- and gene-based prognostic index model.

The Korean Peninsula is considered as a seasonal frozen area that is thawed in the spring and frozen in the winter. The influence of fines of the frost susceptibility of subgrade soils were established by laboratory freezing tests simulating closely the thermal conditions in the field. During the winter season, the climate is heavily influenced by the cold and dry continental high pressure. Because of siberian air mass, the temperature of January is $-6{\sim}-7^{\circ}C$ on average. This chilly weather generate the frost heaving by freezing the moisture of soil and damage potential of the geotechnical structure. In the freezing soil, the ice lenses increase the freeze portion of soil by absorbing the ground water with capillary action. However, the capillary characteristics differ from the sort of soil on the state of freezing condition. In this study, ten soil samples are prepared. The basic physical property tests were performed by following the Korean Industrial Standard and the soil specimens were classified by the Unified Soil Classification System (USCS). These classified soils are used to perform the laboratory opened systems freezing test in order to determine the frost heaving characteristics of soils such as unfrozen water content, heaving amount, and freezing depth.

Forty different apartment houses were subjected to assess the status of indoor - landscaping plants found at each apartment house in Seoul for the year of 1986 and 7989. 1. Comparing with those of 1986, 46% increase in total indoor plant species and 68% increase in the number of them were observed. The most abundant sort found in 1786 was oriental orchid, African violet, Scindapsus, cacti, and Clivia, and in 1989, first with oriental orchid, cacti, Chlorophytum, Clivia and Dracaena, in that order. 2. Foliage ornamental plants were mast popularly found in both years of 1986 and 1989 when considered for horticultural classification of plants. 3. Average plant height ranged between 15 to 30 cm in the year of i986, whereas 31 to 80 cm in 1987, indicaling that the size of plants has greatly increased. 4. Kind of planters or containers was most frequently shown to be made of plastic material in both years, and the porcelain ones have significantly been increased to use recently. 5. Most indoor plants placed at the rooms were on the floor in those years, yet the use of planting shelves became particularly manifesting in the year of 1989. 6. Fittonia and cacti were the most frequently used plant materials for installing terrariums at apartment rooms In the year of 1986, whereas Adiantum and Maranta were so in 1989, indicating that the growers choose much adaptable species in apartment environments. Most of the plants grown to landscaping the indoors was apartment verandas in those years. 8. Average number of indoor plants possessed at each apartment houses surveyed for the year of 1986 was 16 different ones, whereas 27 each In 1789, shoving a noteworthy increase in the number. 9. There have been apparent increase and improvement inhabitant's indoor - plant interest in the years to pass and probably to come.
