This study was carried out to investigate what kind of problems gender equality in Chinese married immigrant women have in marriage. We interviewed five Chinese marriage immigrant women married to Korean men for research. Using the case study method, which is a qualitative research method, five research participants analyzed gender equality awareness and gender equality conflict after migration. As a result, the marital conflicts, which are the difference of recognition of gender equality among married immigrant women, were different according to the family life culture of their home countries, the route of meeting with their husbands, and their understanding of Chinese culture. Nonetheless, most of the research participants showed that they accepted the Korean women's values in the form of conforming to the Korean patriarchal system while taking the inequality by attempting to assimilate positively in Korean society. And some of them resulted in the failure of the family because of the patriarchal values of the Korean husband. Based on the results of this study, we discussed the problems of gender equality in multicultural families in Korea and discussed ways to improve them.

The purpose of this study is to analyze how the satisfaction of Korea life and attitude on sending information is influenced by the information cognition rate of Korea before influx to Korea. The method used for this study was to survey migrant workers in Busan and Kyeongnam area. The results show a tendency towards a higher information cognition when the information was acquired through manpower supply agencies and media information. In addition, among the variables of information cognition, when 'socio-economical' factor was high, the satisfaction rate of Korea life tended to be higher. Also, when the 'workplace environment satisfaction' factor was high, attitude on sending information tended to be positive. Based on those results, this study presented measures for establishing information policies, such as provision of high quality information, diversification of information route which are necessary for migrant workers.

Bladder cancer remains the 10th most common cancer worldwide. In recent years, metformin has been found to have potential anti-bladder cancer activity while high concentration of IC₅₀ at millimolar level is needed, which could not be reached by regular oral administration route. Thus, higher efficient agent is urgently demanded for clinically treating bladder cancer. Here, by conjugating artesunate to metformin, a novel artesunate-metformin dimer triazine derivative AM2 was designed and synthesized. The inhibitory effect of AM2 on bladder cancer cell line T24 and the mechanism underlying was determined. Anti-tumor activity of AM2 was assessed by MTT, cloning formation and wound healing assays. Decreasing effect of AM2 on lipogenesis was determined by oil red O staining. The protein expressions of Clusterin, SREBP1 and FASN in T24 cells were evaluated by Western blotting. The results show that AM2 significantly inhibited cell proliferation and migration at micromolar level, much higher than parental metformin. AM2 reduced lipogenesis and down-regulated the expressions of Clusterin, SREBP1 and FASN. These results suggest that AM2 inhibits the growth of bladder cancer cells T24 by inhibiting cellular lipogenesis associated with the Clusterin/SREBP1/FASN signaling pathway.

Four subtypes of hepatitis B surface antigen are useful in the epidemiologic studies of the route of virus transmission and clinical significance of simultaneous occurance of hepatitis B surface antigen and antibody to hepatitis B surface antigen in the same serum as well as useful marker for population migration. The sera were obtained from 214 HBs Ag positive patients who are diagnosed as chronic liver disease and following up in the Yeungnam university hospital. The subtypes were determined by solid-phase sandwich EIA using monoclonal antibodies. Among 214 specimens, the subtype adr was 93.9%, adw was 2.8%, ayr was 0.9%, ar was 0.9%, adwr was 1.4% and ayw was not detected. There were no correlation between subtype pattern and disease. In summary, the subtype adr was prominent in our study and the difference of subtype pattern by severity of disease was not significant. However, to determine the prognostic value of HBs Ag subtype and relationship between subtype and disease progression, long-term follow up will be needed.

Garolim Bay is not only important fishing ground but also expected area for the tidal power plant. The construction and operation of tidal power plant will make change the ecosystem of this bay. Therefore, the actual fisheries stocks should be precisely understood for the effect estimation and overall utilization of the bay after the construction of the tidal power plant. During the study period from January through December in 1981, forty-six adult fishes species, 3 species of fish egg and 25 fishes larvae species have occurred in the bay. Considering the result on monthly distribution of eggs and larvae, the inner area of the bay seems to be important as nursing ground of larvae spawned at the outside bay in winter, e. g., Ammodytes personatus, and Enedrias sp. This inner bay is also major spawning ground for many species spawning in spring and summer, e. g., Gobiidae, Konosirus punctatus, Engraulis japonica, etc. Taking into consideration the annual mean production for three years($1978{\sim}1980$), there are two major fishing seasons. The one is in May-June for Enedrias larvae stock, and the another in October-November for big eyed herring stock. For the mariculture stocks, short necked clam, oyster and laver are important species. After construction of the tidal power plant, the migratory species, i. e., larvae of Enedrias and Ammodytes personatus, Mugil cephalus, Konosirus punctatus, etc. will be directly damaged by the interuption of migration route. On the otter hand, the change of physico-chemical factors of seawater will also affect the ecosystem of the bay. Consequently, for the overall utilization of the bay after construction, the actual ecosystem including the fisheries stocks, must bs precisely revealed, and the mechanical designs, e. g., sluice position and its demension, should be also considered with these biological characters of the bay.

For a few people's leisure, the natural environment have being deteriorated ceaseless. The plan of the Chungchongpuk Province and the Yungdong District in Chungchongpuk-do which drive foreword the sport and leasure complex designed to construct ski slopes, golf course, and resort hotel in 6,000,000 $m^2$ of natural ecosystem around the Mulhan Valley at Mulhan-ri Sangchon-myon Yungdong-kun Chung-chcngbuk-do by Dongsin Leisure have concerned decrease on biological diversity serious. This study carried out by census Amphibia and Reptilia fauna in the Mulhan Valley to expect the impact of animal diversity by construction of leasure complex and to call attention to understand that impact. 8 species in 5 Families of 2 Orders in Amphibia and 5 species in 2 Families of 1 Order in Reptilia were observed in the Mulhan Valley during June 24, 1994 to June 25, 1994 which showed to be similar to the Natural Park in Korea. 4 of 8 species in Amphibia(Hynobius leechii, Onychodactylus fischeri, Bufo bufo gargarizans, and Rana dybowskii) and 3 of 5 species in Reptilia(Eluphe rufodorsata, Dinodon rufodonatum rufodonatum, and Agkistrodon saxatilus) were revealed the Special Wild Animal recorded by the Ministry of Environment in 1993. Therefore, the Minjujisan seems to have highly reason to conservation by these animal diversity. Around the Minjujisan province was significant connecting the Taebaek Mountains and the Sobaek Mountains on biogeographically with Dokyusan National Park. The plan of Leasure complex in the Mulhan Valley should be cancel in consideration of destruction around the Dokyusan National Park severely by the Muju Resort, Ski slopes, etc. The Minjujisan must be conserve to the Zone of Natural Environment on Amphibia and Reptilia diversity and animal migration route.

An impacted tooth is defined pathologically as a tooth that remains under the mucosa of inside bone without eruption of the crown after a specific period of eruption. Clinically, the term includes those teeth, even before eruption period, that are not expected to erupt due to shape, position and alignment of tooth and lack of space. Canine is prone to impaction more than other teeth because it has the longest time to develop and a complex route from the place of formation to the site of eruption. The impaction incidence of maxillary canine is repoted 0.92$\sim$3.3% (Ferguson, 1990). In 1995 Orton reported that the incidence was 0.92$\sim$2.2% and palatal impaction was more frequent than labial impaction(85%:15%). In 1969 Johnston presented it was more common to woman than to man(3:1). The etiology includes systemic disease such as endocrine disorder, cleidocranial dysostosis, irradiation, Crouzon syndrome, ricketts, facial hemihypertrophy and hereditary and local problems such as ectopic position of the tooth, distance of tooth from its place of eruption, malformation of the tooth, presence of supernumerary teeth, trauma of tooth germ, infection of tooth germ, displacement of tooth germ or tooth by a neoplasm, ankylosis, overretention of deciduous predecessor, lack of space for the tooth in the dental arch and mucosal barrier due to gingival fibrosis. The maxillary canine is especially important as it has the longest root, provides guidance for lateral movement of the mandible and masticatory function and assumes an important role esthetically as it is located at mouth angle. If left untreated, it may cause migration and external, internal resorption of adjacent teeth, loss of arch length, formation of dentigerous cyst or tumors, infection and referred pain as well as malposition of the tooth. Therefore, periodic examination of the development and eruption of the maxillary canine is especially important in a growing child. This case study presents the results of treatment of palatally impacted maxillary canine utilizing surgical exposure and orthodontic tooth movement on patients visiting SNUDH dept. of pediatric dentistry.

Seasonal fluctuations of Riptortus pedestris were investigated in four regions including two sites each at Mt. Yangseong (Munui-myeon, Cheongwon-gun), O-chang (Cheongwon-gun), and Jujung-dong (Cheongju) using aggression pheromone traps from April to November in 2010 and 2011. Aggression pheromone and aggression pheromone + soybean traps were set at all investigated sites, and the Mt. Yangseong A and B sites were investigated at a farmland (80 m, asl) and forest (200 and 300 m). The population density of R. pedestris was high in mid June, mid August, and late October in 2010 and in early May, mid June, mid September, and early October in 2011 with trivoltine. O-chang and Jujung-dong populations, which were distinguished in farmlands and forests, were highest from June to August in the farmland and in September in the forest. Similar numbers of R. pedestris were capture in the farmlands and the forest in June-August, September-November, respectively. From the results of the four regions, more R. pedestris adults were captured in the aggression pheromone + soybean trap than that in the pheromone trap. To investigate the migration route by altitude, 500 R. pedestris adults marked with fluorescent paint were released and re-caught insects were counted in traps after 10 and 20 days. The pattern of the re-caught R. pedestris indicated migration from the forest to farmlands during April-June. These results suggest that the insects did not migrate in August because food was plentiful in the forest at 200 m, but they moved to the forest during October due to the scarcity of food and for overwintering. The R. pedestris seasonal fluctuations in 2011 were affected heavily by the environment, particularly rain precipitation.

This paper reviews comparison analysis of current and latest application for stock identification methods of Todarodes pacificus, and the pros and cons of each method and consideration of how to compensate for each other. Todarodes pacificus which migrates wide areas in western North Pacific is important fishery resource ecologically and commercially. Todarodes pacificus is also considered as 'biological indicator' of ocean environmental changes. And changes in its short and long term catch and distribution area occur along with environmental changes. For example, while the catch of pollack, a cold water fish, has dramatically decreased until today after the climate regime shift in 1987/1988, the catch of Todarodes pacificus has been dramatically increased. Regarding the decrease in pollack catch, overfishing and climate changes were considered as the main causes, but there has been no definite reason until today. One of the reasons why there is no definite answer is related with no proper analysis about ecological and environmental aspects based on stock identification. Subpopulation is a group sharing the same gene pool through sexual reproduction process within limited boundaries having similar ecological characteristics. Each individual with same stock might be affected by different environment in temporal and spatial during the process of spawning, recruitment and then reproduction. Thereby, accurate stock analysis about the species can play an efficient alternative to comply with effective resource management and rapid changes. Four main stock analysis were applied to Todarodes pacificus: Morphologic Method, Ecological Method, Tagging Method, Genetic Method. Ecological method is studies for analysis of differences in spawning grounds by analysing the individual ecological change, distribution, migration status, parasitic state of parasite, kinds of parasite and parasite infection rate etc. Currently the method has been studying lively can identify the group in the similar environment. However It is difficult to know to identify the same genetic group in each other. Tagging Method is direct method. It can analyse cohort's migration, distribution and location of spawning, but it is very difficult to recapture tagged squids and hard to tag juveniles. Genetic method, which is for useful fishery resource stock analysis has provided the basic information regarding resource management study. Genetic method for stock analysis is determined according to markers' sensitivity and need to select high multiform of genetic markers. For stock identification, isozyme multiform has been used for genetic markers. Recently there is increase in use of makers with high range variability among DNA sequencing like mitochondria, microsatellite. Even the current morphologic method, tagging method and ecological method played important rolls through finding Todarodes pacificus' life cycle, migration route and changes in spawning grounds, it is still difficult to analyze the stock of Todarodes pacificus as those are distributed in difference seas. Lately, by taking advantages of each stock analysis method, more complicated method is being applied. If based on such analysis and genetic method for improvement are played, there will be much advance in management system for the resource fluctuation of Todarodes pacificus.
