This study have conducted to calibrate the productivities on the mussel (Mytilus galloprovincialis) cultures in Jinhae Bay. Annual water temperature, salinity and dissolved oxygen have varied to 7.2-$25.9^{\circ}C$, 32.9-34.0 psu, 7.9-8.7 mg/l, respectively. In April, the smallest size of spat, 3.3 mm in shell length, have recruited, and 82.5 mm have recorded to the maximum. In summer, variations of growing up between individuals showed both shell length and weights at same cohort. Annual production at 2 m, 5 m, 8 m depth calculated to 10.91, 10.85 and 9.19 gWWt/ind./yr, respectively. Mussel cultivated in the upper part of the water column (two meter depth) were significantly longer and heavier than those in lower part (eight meter depth). After the recruitment, monthly production showed gradual increment at all positions during summer. As results, annual production of mussel cultivated seemed to be controlled by conditions of growing up in summer. Based on the productivities calculated to this study, the total annual production of the mussel cultivated in Jinhae Bay have estimated about 196 ton/ha/yr.

Five free-living nematode species belonging to the order of Rhabditida are described for the first time in Korea. Two unrecorded species of Rhabditidae, Cruznema tripartitum (Linston, 1906) Zullini, 1982, and Poikilolaimus oxycerca de Man, 1895, and one species of Peloderidae, Pelodera strongyloides Schneider, 1860, were collected in Korea. C. tripartitum has nine pairs of genital papillae arranged in 2+2+1+4 differently from similar species of C. scarabaeum which has ten genital papillae arranged in 2+1+4+3. Poikilolaimus oxycerca has shorter tail (shorter than anal body diameter) compared to similar species of P. regenfussi which has longer tail(longer than anal body diameter). Pelodera strongyloides has shorter tail(1-1.5 times anal body diameters long) than P. punctata (4 anal body diameters long). Two unrecorded species of Panagrolaimidae, Panagrolaimus apicatus Schuurmans Stekhoven & Teunissen, 1938 and Panagrolaimus rigidus (Schneider, 1866) Thorne, 1937 were collected in Korea. P. apicatus has rounded and lower lip compared to similar species, P. margaretae Massey, 1964 which has finely pointed lip. P. rigidus has slender tail and lips rounded and flat barely separated when compared to similar species, P. subelongatus(Cobb, 1914) Thorne, 1937 which has plumper tail and lips are well separated.

According to the survey by the Ministry of Unification, 28,133 live in South Korea as of september 2015 and the number has been steadily increased. It is interesting to note that the majority of defectors were women. Statistics say that the total of women defectors was 1,138 in 2002 and consisted of 55.5%. But the number increased to 2,706 in 2011 and consisted of 70.5%(Wikipedia, 2015). Most of them have trauma, because they experienced terrible events like prostitution, sexual abuse, domestic violence, etc. while they were living in South Korea. They had to get over a lot of challenges they never expected. They had to do whatever they need to do for their survival in South Korea as well as in North Korea. Objectives: This study focuses on identifying the psychosocial resources available for them in order to help them out living here. Method: For this purpose, this study conducted unstructured in-depth interviews with four women defectors from North Korea. Their age bracket is between the ages of 50 and 58 and they have stayed over five years in South Korea. They were recommended by social welfare workers, who had dealt with them over 20 years. For the reliability of this study, the three methods were performed such as three-month close relationship, three-person triangular verification, and diversification of resources-the field notes and observation notes. Results: As a result of this study, the resources may be labeled into three main clusters of themes such as 1) Self-Preservation - 'Self-Love', 'Family-Attachment', 'Share the Goods', 'Live in Harmony', 'Avoidance of conflict'; 2) Self-Conquest - 'Endurance', 'Earnestness and Effort', 'My own Activities', 'Chat', 'Put Down', 'Appreciation and Optimism'; 3) Self-Presence Awareness - 'I was a Precious Daughter', 'I am Mother'. Also there are thirteen sub categories to be considered. Conclusions: This study focuses on identifying how women defectors have used or can use the psychosocial resources available for them, rather than what they have struggled with. It is meaningful to identify in a positive light that this study provides how they have adjusted to a totally different context for their survival and what psychosocial resources they have used. This study can give an idea about how they may receive proper and practical help from the government programs in order to become better used to new living circumstances in South Korea. As well, this study can provide meaningful criteria and guidance with family life educators for women defectors and social workers working in counseling and social welfare areas. This study contributes to better understanding about how they are using these psychosocial resources.

The purpose of this study is to offer basic data of education to improve farm lives though investigating rural homemakers' life style. The results of this study are as follows : 1. The life structure of rural homemakers was classified into two structures as a material resources and human resources. The life style of rural homemakers was classified into systematical life style, traditional value style, social active style, and progressive active style. 2. The life styles of rural homemakers according to social population variance were as follows. The lower of age, homemakers whose family incomes more 30 million won or below 10 million won, who has religions, who employed in livestock were showed at very systematical life style. The homemakers who live in mountain village, higher the much age becomes, and the education level become lower, have showed traditional value style. Rural homemakers the lower of age, the higher incomes, composed of single parent ＋ children who remain single were appeared social active style. Rural homemakers the lower of age, the more shortened farm life periods, who employed in livestock were appeared progressive active style. 3. Systematical life style was more affected by material resources structure, traditional value style was affected by material resources. And social active style was more affected by human resources, progressive active style was affected by human resources.

이 연구의 목적은 노부모에 대해 따로 살고 있는 성인자녀가 제공하는 정서적 지원의 크기가 어떤 요인에 의해 영향을 받게 되는지를 분석하는 것이다. 이를 위해 세대간 가족관계에 있어서의 교환이론적 접근을 분석틀로 하고, \`1998년도 전국 노인 생활실태 및 복지욕구 조사\` 의 자료를 바탕으로 노부모에 대한 별거 성인자녀의 정서적 지원과 이에 영향을 미칠 것으로 여겨지는 요인들-노부모의 인구학적 특성, 상호교환에 있어서의 보상자원 소유여부, 그리고 피 부양욕구-와의 관계를 분석하였다. 다단계 군집 표집법을 통해 추출된 전국의 9,355가구에서 2.535명의 65세 이상 노인을 대상으로 자료가 수집되었는데, 이들 중에서 별거 성인자녀가 있는 2.205명을 분석한 결과 잠재적 보상자원을 지니고 있는 노부모에 대한 별거 성인자녀의 정서적 지원이 잠재적 보상자원을 지니지 못한 노부모의 경우보다 높게 나타나고 있다. 그리고 다른 자녀와 함께 살고 있는 독신 노인에 대한 별거 성인자녀의 정서적 지원이 가장 낮았으며, 수단적 일상생활을 수행하는 데 어려움을 겪는 정도가 심한 노인일수록 별거 성인자녀들로부터 낮은 수준의 정서적 지원은 받았다. 이러한 분석 결과의 일부는 세대간 가족관계가 교환이론을 바탕으로 설명될 수 있음을 실증적으로 보여주고 있으나, 분석에 포함된 변수들이 전체 노민들에게서 나타나고 있는 정서적 지원의 변량을 8.9퍼센트밖에 설명하지 못하고 있다.

This study aims to verify the effect of the rural community living home use through an analysis of depression among the elderly women who live alone in the rural community living home. A survey was conducted from July to September 2015 through direct interviews with 236 elderly people who live alone in community living homes at 52 locations across the country. The main results of this study are as follows. First, social support from family/relatives and neighbors/friends was found not to affect depression in the elderly living in community living homes. Second, satisfaction with health status, economic status and life appeared to affect their depression. This indicates the need for various measures to increase the subjective satisfaction of health. Third, when the demographic characteristics, social support and personal satisfaction were controlled, the period of use, satisfaction with use and operational service/no service were proven to have an impact on depression in the elderly living alone in community living homes. In other words, since the level of satisfaction with community living homes is very high and this has a positive impact on the elderly living in community living homes, it is desirable to have an ongoing policy for the homes to be utilized as important welfare resources. Based on these findings, this study proposes improvements in the user experience and programs and services offered for rural community living home business programs.

We performed a taxonomic study on Korean freshwater bryozoans with the materials collected from 70 localities during 2014 to 2016. A total of 14 Korean freshwater bryozoans are reported through this study. Among them, three Plumatellids, Plumatella fungosa (Pallas, 1768), P. repens (Linnaeus, 1758), and P. reticulata Wood, 1988, are newly added to the Korean fauna. Three species were redescribed with only their statoblasts: Lophopodella carteri, Plumatella rugosa, and Stephanosella hina (Seo, 1998; 2005; Chae et al., 2016). Their colonies were found in Korea for the first time in this study. Since Fredericella sultana, Hyalinella punctata, and Plumatella casmiana were reported from Korea (Toriumi, 1941), neither statoblast nor colony has been found, but we observed them. Living colonies of six species were photographed in the field. Furthermore, the statoblasts of nine species, including three species new to the Korean fauna, were also documented using scanning electron microscopy.
