  • The objective of this study was to monitor and evaluate the schooling characteristics, including the distribution density (volume backscattering strength) and acoustic size (target strength), of commercially valuable species swimming in response to artificial reefs installed at Suyeong Man, Busan, Korea. Fish aggregations at two artificial reef areas and at a nearby natural rocky reef habitat were recorded and analyzed using a 70 kHz split-beam echo sounder and 330 kHz side-scan sonar from August to September, 2006. An underwater CCTV camera system was also used to observe marine organisms in physical contact with and swimming very close to artificial reefs. During the acoustic observations at three reef sites, useful information about schooling characteristics of fish aggregations responding to artificial reefs were obtained, but more trials are needed to confirm significant differences in schooling behavior and geographical distributions in areas containing natural reef structures and artificial reefs.

  • Purpose: To compare of health inequalities between rural and urban areas in term of health status, health behaviors and medical care utilization by using national-wide data. Method: The data came from the 2000 and 2005 census data, 2004 death certification statistics and 2001 national health and nutrition survey. The health indicators used in this study were mortality, perceived health status, health related behaviors, morbidity, accidents and suicides, mental health-related factors, health care accessibility. Korean rural areas have been experiencing a rapid aging process and there are demographic differences between rural and urban populations. Thus, both of crude rates and age-adjusted rates were compared. Result: Although the degrees decreased after adjustment for age, health inequalities between areas still existed. The people who lived in rural areas suffer from higher mortality, morbidity and unhealthy behavior compared to people in urban areas. Especially, regional health inequalities for women were significant. Health care accessibility in rural areas was also lower and medical indirect costs for rural residents were higher than those of urban residents. Conclusion: To reduce health inequalities between geographical areas, political efforts to tackle health inequalities in the rural areas are required.

  • Yunnan, where twenty-six minor ethnics live, is located in Southwest part of China. They have preserved and developed their folk costume, artcraft, music and dance in their peculiar way with natural and cultural surroundings. So, Yunnan is known as a living folk museum. It's worth examining how climate and circumstances change has affected certain differences of dress shape in same ethnic. Research into costumes of minor ethnics can contribute to the study of origin of the trousers, as this group of people have well succeeded the basic form of trousers through their cultural history and everyday life. This study, at first, investigates geographical surroundings of each minor ethnic group, and figures out the style of all trousers by measuring the each size, then compares design color pattern and fabric. The origin of trousers examined by formative characteristics has been classified and comparatively studied. The study materials are twenty-three trousers selected from in Yunnan Folk Museum as well as other relevant literature records. This study suggests that one can examine the type of human culture through the forms of costume which reflects folk custom geography economy etc. This, in turn, can be used as a basic information for other studies, and in particular, for the study of origin and structure of the trousers.

  • The purpose of this research is to study and understand the foreign tourist market's preferences and purchasing behaviors of Korean. Especially this study seeks to achieve this purpose by classifying the preferences and purchasing behaviors by nationality into general product. To confirm this research objective, data was collected with questionnaire method along with literature research. Targeting tourists from Japan, America, and China, the questionnaire survey examined their preferences for general color and design as well as the differences and commonality of their purchasing behaviors. As a result of examining foreign tourists' awareness of traditional tourist souvenir, the significant difference was shown by each country. Also, as for the purchasing behavior and preference for foreign tourists' traditional tourist souvenir, results indicated that Americans consider the element of geographical significance and value more than other groups of tourists. Resultantly, people have a different taste of souvenir in color, design, transform and so on by nationality.

  • The objective of this study was to identify role types as they pertain to paternal and maternal grandmothers based on four role dimensions. To this end, a sample of 416 mothers of preschoolers was used. This study also examined correlates of and differences in the type of grandparents in terms of paternal and maternal types of grandmothers. Data were analyzed by K-means clustering, Chi-square, and multi-nominal logistic regression analysis. Grandmothers were classified into five distinct groups : influential, supportive, authority-oriented, passive, and detached types. Maternal grandmothers seemed to be relatively more involved with their grandchildren than paternal ones. The type of grandmothers varied as a function of socioeconomic status, the number of grandchildren, and geographical proximity for paternal grandmothers, and mothers' employment status and the closeness between grandmothers and mothers for maternal grandmothers. The results imply that grandmothers are currently becoming more active in their grandchildren's lives and that kinship in Korean society tends to lean to the maternal side.

  • The purposes of this study is to investigate the present condition of nurses' uniform design and to categorize the image of nurses' uniform design. To investigate the nurses' uniform design, total 241 data were collected from the pictures of nurses who work for private hospital and semi-general hospital in Deajeon and Seoul city and Chungnam province and the pictures of uniform for nurses in general hospital presented at nurses' uniform company web sites. This data was evaluated by 3 major garment characteristics, yin/yang, casual/professional, and lightness/ darkness-were used as criteria for categorizing the image of nurses' uniform design. Focus group consisting of 10 experts majored in Clothing and Textiles were evaluated by 7 point Likert type scales. Nurses' uniform design at the present time showed equal distribution in terms of yin/yang and casual/professional. However, in terms of lightness/darkness, nurses' uniform design were partial to light image. Therefore, dark image, specially dark and masculine image in nurses' uniform design were very rare. Nurses' uniform design had some differences by type of hospital, department, and geographical area. The most important meaning from the result through this study was that the nurse uniforms were classified into groups according to the present condition of nurses' uniform design.

  • Interstate electric power system, as an alternative for energy cooperation under regional economic bloc, has been hotly debated before progressing the restructure in electric power industry and rapidly expanded in many regions after 1990s. Especially, since northeast asia has strong supplementation in resource, load shape, fuel mix etc., electric power system interconnection in this region may bring considerable economic benefits. Moreover, since Korean electric power system has a great difficulty in a geographical condition to interrupt electricity transaction with other countries, it has been expanded as an independent system to supply all demand domestically. As a result, Korean electric power system makes considerable payment for maintaining system security and reliability and expands costly facilities to supply a temporary summer peak demand. Under this inefficiency, if there are electricity transactions with Russia via the North Korea route then economic electric power system operation nay be achieved using seasonal and hourly differences in electricity price and/or load pattern among these countries. In this paper, we estimate price cap of transacted electricity via interstate electric power system in northeast asia. For this study, we perform quantitative economic analysis on various system interconnection scenarios.

  • This study provides the first report of the presence of Coolia malayensis in the Mediterranean Sea, co-occurring with C. monotis. Isolated strains from the Gulf of Gabès, Tunisia (South-eastern Mediterranean) were identified by morphological characterization and phylogenetic analysis. Examination by light and scanning electron microscopy revealed no significant morphological differences between the Tunisian isolates and other geographically distant strains of C. monotis and C. malayensis. Phylogenetic trees based on ITS1-5.8S-ITS2 and D1-D3/28S rDNA sequences showed that C. monotis strains clustered with others from the Mediterranean and Atlantic whereas the C. malayensis isolate branched with isolates from the Pacific and the Atlantic, therefore revealing no geographical trend among C. monotis and C. malayensis populations. Ultrastructural analyses by transmission electron microscopy revealed the presence of numerous vesicles containing spirally coiled fibers in both C. malayensis and C. monotis cells, which we speculate to be involved in mucus production.

  • Jejudo has unique geographical and climatologic characteristics compared with other areas in Korea. The aim was to evaluate differences of the nationwide notifiable infectious diseases (NND) occurred in Jejudo, 2011~2018. The source of data was on the Infectious Disease Statistics System operated by Centers for Diseases Control & Prevention in Korea between 1 January 2001 and 30 September 2018. After calculating the proportion of sum of years showing a higher incidence in Jejudo than nationwide divided by sum of comparing years(PSYH), authors defined the infectious diseases for control in Jejudo (IDCJ) with PSYH over 75%. In addition, the infectious diseases showing increasing trends during recent 2 years(2015~2018) were defined as sudden increase Infectious diseases for control (SIDCJ). IDCJ in 2001~2018 included 3 NNDs such as chicken pox, syphilis, and Streptococcus pneumoniae. The results support main evidences to plan strategies and distribute community resources for control and prevention of NNDs in Jejudo, Korea.

  • This paper explores the hyperlink structures of the official websites for the following terrestrial TV networks: ABC(US), BBC(UK), NHK(Japan), and KBS(Korea). These websites were selected and visualized to analyze the hyperlink structure and examine the connection relations among the TV networks. A total of 4378 data was collected through the Voson site and were analyzed with NodeXL. Results shows that NHK's network demonstrates a good network structure at a quite high level, holding more related websites than BBC. We discovered that ABC TV network has the largest effect with the largest number of out-links. Surprisingly, structures of BBC and NHK were quite similar, overcoming geographical and cultural differences. Thus, both TV networks were seen to be progressive and open. On the contrary, ABC and KBS were considered to be relatively conservative. A comprehensive review of the "category points" combination chart revealed that NHK's official website has the widest variety of hyperlinks. The shortest distance of a hyperlink between a website type and a TV network meant that the TV network has a larger number of links to those website types than other TV networks do. The result may provide Internet users to efficiently select TV network web pages according to the types of information they want to find out.
