We attempted to estimate potential habitats of Clithon retropictus and to determine the community structure of benthic macroinvertebrates by presence of C. retropictus. 2016 to 2018 database of "Survey and Assessment of Estuary Ecosystem Health" by the Ministry of Environment were used to identify the distribution site of C. retropictus. The occupancy model was applied to estimate the potential habitat of C. retropictus. Four diversity indices were used to confirm the community structure of benthic macroinvertebrates. C. retropictus was found in the southern coast area and part of the east coast, and this pattern was consistent with previous studies. Additionally, the occupancy model predicted that a potential habitat of C. retropictus could appear in the west coast area. The community structure of benthic macroinvertebrates was relatively high at the site with C. retropictus than the site without C. retropictus. Therefore, the occupancy model can be considered when conserving C. retropictus inhabiting a limited area. Additionally, C. retropictus can be used to the indicator species that can represent the brackish water environment.

By examining the constitutive characteristics of Yon-Ko-Jeon and analyzing the lived meanings and experiencing essence of students, this study details the students' awareness, responses, and strategies with regards to the phenomenon of women's alienation from Yon-Ko-Jeon. Students from the two colleges were divided into two groups- one which was aware of women's alienation from Yon-Ko-Jeon, and another group that was unaware of such a phenomenon. Students without awareness tended to perceive the alienation of women from Yon-Ko-Jeon as a natural phenomenon. On the other hand, the members who had awareness tended to see it as a phenomenon that was either justified, unequal, or in need of change. In the latter group, those who saw women's alienation as a justified phenomenon responded with tolerance and adopted a bystander strategy. Conversely, those who saw it as an unequal phenomenon responded with rejection and instead chose to adopt anti-/alternative Yon-Ko-Jeon strategies. The last group, which perceived women's alienation as a phenomenon in need of change, adopted correcting responses as well as intercollegiate solidarity and cooperation strategies. A generalization of the findings reveals that the students' experiencing essence of the phenomenon extends from critical thinking to awareness, response, and strategy in a step-by-step and sequential process. Through this study, it was found that the students' experiencing essence all follow a continuous thinking pattern, as illustrated in the diagram provided.

The purpose of this study was to explore integrated approaches to physical education in general education by examining methodology of physical education aiming for convergence education. This case study was conducted, using a qualitative approach during March, 2017 to November, 2017. Data were collected through non-participant observation, in-depth interviews, field-notes, students' journal, syllabus and lecture materials. The key findings are as follows: First, "Emotion Coaching through Movement" is a course of 'understanding of body' approaching integrated humanities science and natural science. Second, it is a convergence education, conducting 'text to daily practice' by approaching positive psychology and neurophysiology. Third, it is a physical education with 'integrated theory and practice' in higher education. These results indicate that students can understand their own body, observe their daily and fixed movement or reaction pattern, and enhance the ability of understanding others through a physical education in general education.

Variations in water temperature are known to affect almost every part of fish physiology. The rise in water temperature due to climate change can physically damage fish. This study was conducted to evaluate the health status of the Atlantic salmon (Salmo salar) at high water temperature (20℃) than the optimum water temperature (15℃). Liver tissue exerts important metabolic functions in thermal adaptation. Therefore, liver tissue was used in this study. The evaluation method is to develop the biomarker gene using NGS RNAseq analysis and to examine the expression pattern using RT-qPCR analysis. The NGS RNAseq analysis revealed 1,366 differentially expressed genes, among which 880 genes were increase expressed and 486 genes were decrease expressed. The biomarker genes are such as heat shock protein 90 alpha (Hsp90α), heat shock protein 90 beta (Hsp90β) and cytochrome P450 1A (CYP1A). The selected genes are sensitive to changes in water temperature through NGS RNAseq analysis. Expression patterns of these genes through RT-qPCR were similar to those of NGS RNAseq analysis. The results of this study can be applied to other fish species and it is considered to be useful industrially.

The purpose of the study w3s to investigate the consumption pattern of the Korean traditional foods of the elementary schoolchildren living in urban and rural area. For the investigation, 373 fifth-grade elementary schoolchildren in Incheon and Gangwhado were surveyed by a questionnaire and the data were analyzed by the SPSS 10.0 program. As for the frequency to take the Korean traditional foods, bab and kimchi are taken almost everyday, and gug, jjigae, jorim, gui, namul are taken frequently. And juk, jeongol, jeon, sanjeog, jutgal, hangwa and umryo were shown to be taken occasionally. There were statistical differences in the frequencies of the Korean traditional food consumption by the residence and the gender. The students in urban area take hinbab, jabgokbab, hobakjuk deonjanggug, sangsunjorim, jangiorim more frequently than the students in rural area. The students in rural area take mandu, kuksoo, yeongunjorim and kongiorim more frequently than the students in urban area Female students take sangsunjorim, jangiorim, sangsungui, bulgogi, sangsunjeon, hobakjeon, sukchae, jutgal and oiji more frequently than male students. Most of the schoolchildren answered that in the future they would like to take the traditional foods more frequently than now. There was statistical difference by the gender. As for the food such as bibimbab, gug, jjigae, jeon, namul and jang-aji, female students responded to take more frequently than male students. The 39.1% of them responded that the taste is the point to be most improved in the future. But there was no statistical difference by gender and the residence In order to make the taste of traditional food more attractive to modem people, the 37.8% of them replied it does not need to change the traditional preparation method. However, similar percentage of the schoolchildren(35.7%) answered it is needed to change partly the traditional preparation method. As for the effect of traditional foods on health, the 68.4% of schoolchildren thought that the our traditional foods are healthier than western foods.

The purpose of this study is to describe how the structural and functional features of social network change among widowed middle and older adults and to examine the effect of personal predictors of the social network change. Data was obtained from men and women between 45 to 98 years of age(N=118) who were bereaved by the death of their spouse since the first wave survey and participated in the second wave survey of the Korean Longitudinal Study of Ageing(KLoSA). The main findings are as follows: First, their social network after the bereavement was strengthened centered around children; for example, the number of adult children living in proximity to the parent, frequency of contact with children, and the financial and non-financial support from children generally increased. Second, the social network change pattern was categorized into four types such as "overall increased type," "children-centered increased type," "children/close relationship-centered increased type," and "stagnation type." Finally, the health condition of the widowed middle and older adults was a strong predictor of the social network change.

The present study aimed at investigating how Korean housekeeper in midlife revaluate their lives. For this purpose, 14 housekeepers whose youngest child was at least older than high school students were interviewed in a semi-structured retrospective method. The interview was focused on relational, psychological, and economical aspects of the participants before and after marriage each. The interview usually continued one and a half to two hours. The phenomenological method describing personal meaning of experiences was referred to for data analyses by transforming retrospective life story of participants into key meaningful units. According to main retrospective contents of each stage of development, the participants' childhood and adolescence was characterized by familial circumstances, formation of personality and value, and career choice. Main themes of their early adulthood were spouse selection and marriage, marital adaptation, and family relationships. Their midlife focused on children, economic and emotional stability, family relationships, acceptance of their spouse and themselves, and health and religion. Life styles of the participants were analyzed in terms of turning events, meanings of current life, and cumulative effects of life events. These findings were discussed in terms of developmental pattern in relation to the established theory of development.

Objective: The purpose of this study is to report the efficacy of using Korean medicine treatment with cold hypersensitivity of the hands and feet with lumbar spinal herniated intervertebral disc. Case presentation: We used Korean medicine treatment (Gyejigabuja-tang, acupuncture) to treat a hospitalized patient with cold hypersensitivity of the hands and feet with lumbar spinal herniated intervertebral disc. To evaluate the treatment, we used the Numerical Rating Scale (NRS). The degree of cold hypersensitivity of the hands and feet was also evaluated using evaluation paper. The generic health status was measured using the European Quality of Life-5 Dimensions (EQ-5D) scale. The 31-year-old female underwent 13 days of inpatient treatment. Her pattern identification was that both hands and feet are cold (BiYangHeo) types. The treatments were herbal medicine and acupuncture. She took Gyejigabuja-tang for 13 days. She also received acupuncture for 20 minutes twice a day at LI11 (曲池), L14 (合谷), TE5 (外關) on her hands, LR3 (太衝), SP6 (三陰交), SP9 (陰陵泉) ST36 (足三里), GB41 (足臨泣) on Feet, GV4 (命門), GV3 (腰陽關), BL23 (腎兪), BL24 (氣海兪), BL25 (大腸兪), and BL26 (關元兪) on the low back. After 2 weeks of treatment, the NRS scale of her cold hypersensitivity of hands and feet symptoms dropped from NRS 7 to NRS 3, and her low back pain dropped from NRS 6 to NRS 3. Her cold hypersensitivity of hands and feet evaluation paper score decreased from 64 to 32, and her EQ-5D increased from 0.487 to 0.681. After the end of treatment, continued symptom improvements and no significant side effects were confirmed. Results: These findings suggest that Korean medical treatment (Gyejigabuja-tang, acupuncture) may be effective for treating cold hypersensitivity of hands and feet with lumbar spinal herniated intervertebral disc. The NRS, evaluation paper, and EQ-5D scores improved after treatment, with no side effects.

Objectives: The study aimed to understand the current treatment patterns in Korean medicine to develop clinical practice guidelines for autonomic dysfunction in Korean medicine. Methods: This study sent an online survey vai text message to 25,900 Korean medicine doctors whose contact information was registered with the Association of Korean Medicine. A total of 1,410 Korean medical doctors completed the online survey. Results: When autonomic treating dysfunction clinically, 77% of the cases included only a description without entering a diagnosis code. The most commonly used information to diagnose o autonomic dysfunction was history-taking and symptoms (79%), and the main symptoms of autonomic dysfunction were palpitations, dizziness, sleeping difficulties, anxiety/nervousness, and depression/lethargy. The most frequently mentioned cause of autonomic dysfunction was mental problems (54%). The most commonly used Korean medicine treatment method for autonomic dysfunction was herbal medicine (70%), and Soyo-san/Gamisoyo-san is the most frequently used herbal medicine preparation. Liver qi depression used to indicate the most often mentioned Korean medicine pattern identification used to indicate autonomic dysfunction (31%). When asked whether cardiac neurosis in Chinese medicine can be considered autonomic dysfunction, opinions for and against it are determined almost equally. Conclusions: Our results serve are a foundation for developing clinical practice guidelines for autonomic dysfunction in Korean medicine and are expected to catalyst promoting future clinical research on autonomic dysfunction.

Hyperprogressive disease (HPD) is a distinct pattern of progression characterized by acceleration of tumor growth after treatment with anti-PD-1/PD-L1 Abs. However, the immunological characteristics have not been fully elucidated in patients with HPD. We prospectively recruited patients with metastatic non-small cell lung cancer treated with anti-PD-1/PD-L1 Abs between April 2015 and April 2018, and collected peripheral blood before treatment and 7-days post-treatment. HPD was defined as ≥2-fold increase in both tumor growth kinetics and tumor growth rate between pre-treatment and post-treatment. Peripheral blood mononuclear cells were analyzed by multi-color flow cytometry to phenotype the immune cells. Of 115 patients, 19 (16.5%) developed HPD, 52 experienced durable clinical benefit (DCB; partial response or stable disease ≥6 months), and 44 experienced non-hyperprogressive progression (NHPD). Patients with HPD had significantly lower progression-free survival (p<0.001) and overall survival (p<0.001). When peripheral blood immune cells were examined, the pre-treatment frequency of CD39⁺ cells among CD8⁺ T cells was significantly higher in patients with HPD compared to those with NHPD, although it showed borderline significance to predict HPD. Other parameters regarding regulatory T cells or myeloid derived suppressor cells did not significantly differ among patient groups. Our findings suggest high pre-treatment frequency of CD39⁺CD8⁺ T cells might be a characteristic of HPD. Further investigations in a larger cohort are needed to confirm our results and better delineate the immune landscape of HPD.
