This study aims to quantitatively evaluate the conservation priorities of unexecuted urban parks in Seoul both from an ecological and public perspective. To this end, two methodologies, ecological network analysis based on graph and circuit theory and accessibility analysis, were employed in order to assess ecological connectivity of and public accessibility to unexecuted parks, respectively. This study applied linkage-mapping methods (shortest path and current flow betweenness centrality) of connectivity analysis to an integrated map of landscape permeability. The population-weighted accessibility to unexecuted parks was measured based on a negative exponential distance decay function. As a result, for both ecological connectivity and accessibility, Gwanaksan, Suraksan, and Bulamsan urban natural parks are found to be the most important (rank 1-3) to be conserved. For these sites, inner park areas with conservation priorities for connectivity and accessibility were identified. The findings of the study can be used for giving conservation priority to the unexecuted urban parks in terms of long-term sustainable urban planning.

From pathological view, Gwoleumbyeong(厥陰病) may be explained as extreme reduction of Gwoleumgyeonggi(厥陰經氣) due to immoderate Wihan(胃寒). Also, concerning regions of human body, Gwoleumbyeong has close relation to lower abdomen and genital, which are the origins of Gwoleum meridian[厥陰經]. Therefore, it is appropriate that the nature of Gwoleumbyeong be described as Hangeukyangul(寒極陽鬱), rather than Sangyeolhahan(上熱下寒), Hanyeolchakjap(寒熱錯雜). Sangyeolhahan, Hanyeolchakjap does not represent Gwoleumbyeong to the full extent, in a sense that the term views Hanyeol(寒熱) as two equal rank, whereas pathogenesis of Gwoleumbyeong depends on the sole extremity of Wihan(胃寒). The reason that the nature of sanghallon(傷寒論) be regarded as Sangyeolhahan, Hanyeolchakjap has been lying on the presupposition that whole symptoms of Hangwol (寒厥), Yeolgwol(熱厥), diarrhea[下利], vomiting[嘔吐] and hiccup, from "Gwoleumpyeon(厥陰篇)",may be categorized into Gwoleumbyeong. However, the symptoms described above do not show Gihwa(氣化) characteristic of Gwoleum(厥陰) and follow the regional distribution of Gwoleumbyeong, from which it can be pointed that those symptoms have no relation with Gwoleumbyeong. Ever since the theory of Yukgigihwa(六氣氣化) was used to comprehend and interpret "Sanghallon", Gwoleumbyeong has been thought as equivalence of Gwol(厥), which led to misunderstanding of Sangyeolhahan, Hanyeolchakjap. However, Gwoleumbyeong from "Sanghallon" has been argued in specific, through the historical practice of Sanghan(傷寒) as pathogen, particular state of meridian and correlation of meridian and Byeongjeung(病證).

Purpose: The purpose of this study was to identify the impact of cigarette smoking and alcohol consumption on the incidence of colon cancer in adults with metabolic syndrome. Methods: This study employed a longitudinal study design and utilized secondary data drawn from the Korean Genome and Epidemiology Study (KoGES). The data of a sample of 2,327 adults with metabolic syndrome tracked every two years from 2001 to 2014 were used in this study. Statistical data analyses of the frequency, number of cases per 100,000 person-years, log-rank test, Kaplan-Meier curve, and Cox's proportional hazards regression were performed using IBM SPSS statistics version 24. Results: During the observation period, the number of colon cancer cases was 46, and the total person-years were 252,444. The incidence of colon cancer was higher in current, over 10 pack-year smokers when compared to non-smokers (hazard ratio=3.38, 95% confidence interval=1.09~8.42). Conclusion: Excessive and long-term smoking should be avoided to prevent colon cancer, especially in adults with metabolic syndrome, since it might exacerbate the risk factors of colon cancer. Particularly, health professionals need to provide individualized smoking cessation interventions to those at high risk of colon cancer.

Purpose: In this study, we investigated the effectiveness of a 12-week virtual reality exercise program using the Nintendo Wii console (Wii) in improving balance, emotion, and quality of life among patients with cognitive decline. Methods: The study included 30 patients with cognitive decline (12 female, 18 male) who were randomly assigned to an experimental (n=15) and control groups (n=15). All subjects performed a traditional cognitive rehabilitation program and the experimental group performed additional three 40-minute virtual reality based video game (Wii) sessions per week for 12 weeks. The berg balance scale (BBS) was used to assess balance abilities. The short form geriatric depression scale-Korean (GDS-K) and the Korean version of quality of life-Alzheimer's disease (KQOL-AD) scale were both used to assess life quality in patients. Statistical significance was tested within and between groups before and after treatment, using Wilcoxon signed rank and Mann-Whitney u-tests. Results: After 36 training sessions, there were significant beneficial effects of the virtual reality game exercise on balance (BBS), GDS-K, and KQOL-AD in the experimental group when compared to the control group. No significant difference was observed within the control group. Conclusion: These findings demonstrate that a virtual reality-training program could improve the outcomes in terms of balance, depression, and quality of life in patients with cognitive decline. Long-term follow-ups and further studies of more efficient virtual reality training programs are needed.

Purpose: This study aimed to verify the effects of a community-based fall prevention exercise program for older adults on lower extremity muscle strength, balance ability, and fall efficacy. Methods: This study recruited 30 participants, and the program was conducted for 10 weeks. The program included sessions on strength and balance exercises, conducted for 50 minutes a day and at least three times a week. The collected data were analyzed using non-parametric (Wilcoxon signed-rank test, generalized estimated equation) and parametric statistics (paired t-test, rmANOVA). Results: After 12 weeks of exercise program, lower extremity muscle strength and static-dynamic balance ability significantly increased. The fall efficacy increased from an average score of 2.48 points before the test to an average score of 2.91 points after the test. Regarding general characteristics, there were no significant differences in effect before and after the program, except for fall efficacy. Conclusion: The above results showed that the intervention of a community-based fall prevention exercise program for older adults was effective. Therefore, it is suggested that this exercise program be organized regularly within the center to provide periodic and long-term services.

Purpose - This study investigates research trends by searching for English keywords and abstracts in 1,511 Korean journal articles in the Korea Citation Index from the 2002-2019 period using the term "Port." The study aims to lay the foundation for a more balanced development of port research. Design/methodology - Using abstract and keyword data, we perform frequency analysis and word embedding (Word2vec). A t-SNE plot shows the main keywords extracted using the TextRank algorithm. To analyze which words were used in what context in our two nine-year subperiods (2002-2010 and 2010-2019), we use Scattertext and scaled F-scores. Findings - First, during the 18-year study period, port research has developed through the convergence of diverse academic fields, covering 102 subject areas and 219 journals. Second, our frequency analysis of 4,431 keywords in 1,511 papers shows that the words "Port" (60 times), "Port Competitiveness" (33 times), and "Port Authority" (29 times), among others, are attractive to most researchers. Third, a word embedding analysis identifies the words highly correlated with the top eight keywords and visually shows four different subject clusters in a t-SNE plot. Fourth, we use Scattertext to compare words used in the two research sub-periods. Originality/value - This study is the first to apply abstract and keyword analysis and various text mining techniques to Korean journal articles in port research and thus has important implications. Further in-depth studies should collect a greater variety of textual data and analyze and compare port studies from different countries.

This investigation is aimed at automatic text summarization on large-scale Vietnamese datasets. Vietnamese articles were collected from newspaper websites and plain text was extracted to build the dataset, that included 1,101,101 documents. Next, a new single-document extractive text summarization model was proposed to evaluate this dataset. In this summary model, the k-means algorithm is used to cluster the sentences of the input document using different text representations, such as BoW (bag-of-words), TF-IDF (term frequency - inverse document frequency), Word2Vec (Word-to-vector), Glove, and FastText. The summary algorithm then uses the trained k-means model to rank the candidate sentences and create a summary with the highest-ranked sentences. The empirical results of the F1-score achieved 51.91% ROUGE-1, 18.77% ROUGE-2 and 29.72% ROUGE-L, compared to 52.33% ROUGE-1, 16.17% ROUGE-2, and 33.09% ROUGE-L performed using a competitive abstractive model. The advantage of the proposed model is that it can perform well with O(n,k,p) = O(n^(k+2/p)) + O(nlog₂n) + O(np) + O(nk²) + O(k) time complexity.

Increasing life expectancy leads to a rise in the prevalence of aging-related mental diseases and a concomitant increase in the financial and societal pressures related to their prevention and management. This issue is attracting increasing attention from researchers. Therefore, this study aimed to determine whether a healing program in a forest environment is effective for improving cognitive function, depression, anxiety, and stress in elderly people. A nonequivalent control group pretest-posttest design was used. The experimental group consisted of 18 males and females aged 60 to 80 years who participated in a forest healing program for seven days, while the comparison group comprised 10 people with similar demographics. For the process of data analysis, this study performed a cross-analysis to determine the homogeneity of the data and carried out the Wilcoxon signed-rank test, a nonparametric statistical test, to verify the significance of each group. Participation in the forest healing program led to a significant improve-ment in cognitive function (p=0.030). The levels of depression decreased, but this result was not statistically significant. The levels of anxiety decreased significantly (p=0.004). The mean cortisol score, a measurement of stress, decreased, but it was not statistically significant. These findings confirmed the effectiveness of this program for improving certain mental conditions of elderly people, and affirmed that the use of long-term forest healing programs can be expected to alleviate national pressures created by aging societies.

본 연구는 노인의 장기요양보호서비스 이용 유형별 부양가족의 부양스트레스 경로를 분석하여 그 함의를 논의하는 데 목적이 있다. 조사대상자는 2008년 7월부터 시행되고 있는 노인장기요양제도의 적용 대상자로 인정받은 65세 이상 노인과 그 부양가족이었고, 비확률표집을 통하여 주부양자를 대상으로 방문요양서비스와 노인요양서비스 유형을 구분하여 설문조사하였다. 회수된 설문지 중에서 방문요양 151부, 노인요양시설 107부 총 258부가 본 연구의 분석 표본으로 사용되었다. 분석결과는 다음과 같았다. 첫째, 시설이용 노인은 재가서비스 이용 노인에 비하여 상대적으로 여성비율과 고연령, 사별의 비율이 높고, 자녀수는 많았다. 둘째, 시설이용 노인은 평균적으로 재가서비스이용 노인에 비하여 ADL제한이 심하고 주요 질병으로 치매나 중풍의 비율이 높고 요양등급의 수준이 높았지만 그 반대인 경우도 있었다. 셋째, 재가서비스이용 노인의 주부양자는 시설이용 노인의 주부양자에 비하여 여성, 고연령, 저학력의 비율이 높았고, 관계는 배우자와 며느리의 비율이 높았으며 건강상태가 나쁘고 소득이 낮은 편이었다. 넷째, 장기요양서비스 이용 유형별로 부양자의 스트레스 경로형태에서 차이를 보였다. 즉, 장기요양서비스 유형별로 1차 스트레스 요인이 2차 스트레스요인에 미치는 경로방향이 다르고, 2차 스트레스요인이 우울에 미치는 경로도 다르다. 특히 방문요양 이용 부양자는 자아상실이 우울에 크게 영향을 미치는 경로를 보여주지만 노인요양시설 이용 부양자는 자아상실이 우울에 미치는 경로가 전혀 형성되지 않았다. 다섯째, 부양가족의 스트레스인 우울에 직접 영향을 미치는 스트레스 요인들은 장기요양 서비스 이용 유형별로 차이를 보였다. 즉, 방문요양의 경우엔 2차 스트레스 요인 모두가 직접 영향을 미친 반면, 노인요양시설의 경우엔 2차 스트레스 요인 중 근로갈등과 가족갈등이라는 두 개의 요인은 우울에 직접적인 영향을 미쳤지만, 자아상실은 영향을 미치지 않았다. 따라서 노인 부양가족의 스트레스를 경감시키는 정책이나 프로그램이 장기요양보호서비스 이용유형에 따른 스트레스 요인과 스트레스 경로를 반영하여 다르게 설계되어야 한다는 것을 알 수 있다.
