This study aimed to develop a Korean word tool related to solitude and loneliness. Because collecting the right words is very important, words that express the two emotions were selected from three language dictionaries. At this time, related words were collected to specifically reflect the increasing number of people seeking voluntary solitude. Consequently, 1,768 words were collected. From these, 684 words were selected based on specific criteria that everyone can understand and use, and they went through a six-iteration selection process, which extracted a total of 243 words. Considering the nature of the study, the meanings of the words collected must be clear and comprehensively represent the overall aspects of solitude and loneliness. Accordingly, a total of 243 words were selected, focusing on words that received the highest ratings in terms of familiarity and appropriateness. It is expected that this study will establish a clear concept of solitude and loneliness and provide basic data that can be used to understand the realistic and universal perception of Koreans from a developmental perspective.

Traditional syntax-oriented serializability notions ate considered to be not enough to handle in particular various types of transaction in terms of duration of execution. To deal with this situation, altruistic locking has attempted to reduce delay effect associated with lock release moment by use of the idea of donation. An improved form of altruism has also been deployed in extended altruistic locking in a way that scope of data to be early released is enlarged to include even data initially not intended to be donated. In this paper, we first of all investigated limitations inherent in both altruistic schemes from the perspective of alleviating starvation occasions for transactions in particular of short-lived nature. The idea of two-way donation locking(2DL) has then been experimented to see the effect of more than single donation in client-server database systems. Simulation experiments shows that 2DL outperforms the conventional two-phase locking in terms of the degree of concurrency and average transaction waiting time under the circumstances that the size of long-transaction is in between 5 and 9.

Childhood psychic trauma appears to be a crucial factor in the development of serious disorders both in childhood and in adulthood. Traumatized children show strong tendency to revisualize or re-feel a traumatic events. Play and behavioral reenactments are frequent manifestations of both the single blow and the long-standing traumas in childhood. Those children who suffer the results of single, intense terror appear to exhibit detailed memory, retrospective reworkings and misperceptions. In long-standing or repetitive trauma, children would show psychic numbing, self-hypnosis, dissociation and rage. Child's brain is undergoing critical and sensitive periods of differentiation. During this time, developing central nervous system is exquisitely sensitive to stress. Stressor-activated neurotransmitters and hormones can play major roles in neurogenesis, migration, synaptogenesis, and neurochemical differentiation. Internal opiate system operates in some trauma and causes the victim to fail to respond, to avoid, to shut off feelings. Evidence is also accumulating in traumatology that dysfuntion of locus coeruleus and ventral tegmental neucleus system leads to catecholamine receptors hypersensitivity. This change result in hypervigilance, increased startle, affective lability, and increased autonomic nervous system hyperreactivity. Another site of action of trauma on the brain is hypothalamic-pituitary-adrenal axis. Individuals with PTSD do not have enough cortisol to halt the alarm reaction. When children are exposed to long-standing extreme events, massive attempts to protect the psyche and to preserve the self are put into gear. These developmental traumas mobilize various kinds of defense mechanisms. Massive denial, dissociation, self anesthesia, identification with aggressor and aggression turned against the self often lead to profound character changes in the youngsters.

Comovement of international stock market prices has been lately a major controversy in the global stock market. This paper explores whether the common trend has really existed among the US, Japan and Korea's stock markets using the econometric techniques such as VAR, VECM as applied. Pair of indices from the exchange market and the over-the-counter market in each country has been tested, and the exchange market only has been turned out that the common trend existed. The dynamic analyses using the Granger causality test, impulse response function, and the forecast error decomposition have followed to show that the US stock market has played some important role in the Korea and Japan's market in the exchange as well as in the OTC market. The results of the paper imply that the more careful investigation with respect to the co-integration may be necessary in the global market integration studies.

As the results of studies based on the Russian Activities-Oriented Theory, the gifted students in many fields have common insights for the true nature of the problem, or the actual state. From Russian Activities-Oriented Theory of view, gifted students have the ability to discern the essential elements involved in each actual state and change of state of things, and to solve the problem, based on these elements. Enhancing these abilities of the students, the educator can develop the average student into a gifted one. This study result of the Russian specialist suggests the possibility of a stream of education that can develop gifted students. Hence, this paper discussed the points and processes of formation of the Russian Activities-Oriented Theory, and inquired on what is the true nature of the problem or the meaning of actual state and how it affects the studies of the student. The paper also investigated the actual conditions of wrong learning about some mathematical concepts and discussed the role of insights to the true nature of the problem in the learning process of the student.

This study is about applying the concept of moral injury in reinterpreting and understanding the experience of female North Korean refugees who have experienced psychological trauma and are struggling with adjusting in their everyday lives. The database KISS and DBpia were used to search for academic peer-reviewed articles published before August 13th in 2017, using 'female or women North Korean,' 'female or women relocated North Korean,' and 'female or women North Korean defector' as keywords. In total 51 studies were finally selected for content analysis and the result were the following. First, listing from the most often occurring study topic to the least occurring topic in order: post-defection adjustment related, mothering experience, experience of North Korean regime and Korean War, work or job or employment related, recovering from psychological trauma as well as growth and resilience related, experiences in China, trauma and psychological difficulties, anxiety treatment process and effects. Second, words related to psychological aspect of moral injury appeared 260 times in 51 selected studies, changes in the existential belief appeared 82 times, cognitive aspects of moral injury appeared 71 times, and behavioral aspects 21 times. Third, two main contexts emerged to be the antecedent that led to moral injury and they were 'identity denial' and 'dismantled family.' In attempts to find opposite cases or stories where aspects of moral injury were not found despite the existence of its antecedents and it was 'identity restructuring.' Based on the finding, practice implications that could help female North Korean refugees prevent or recover from moral injury were suggested.

This study has three objectives. One of them is to debate on the incompatible Neo-Malthusianism and Comucopianism, which give us a comparative gauge for analysis of the population elements in Korea and Japan. The other is to investigate how a variety of population elements are related to specific regions, Korea and Japan. And the last is to compare and analyze the residential preference pattems and the degree of care for the future life for the aged over 50 ages. Various elements in population show that Japan is of type superior to Korea, and that the gap between two countries is getting narrow every year. Wiber's migration expectancy is much higher in Kwangiu-si and Chollanam-do than in Hiroshima-ken. Burial customs in funeral ceremony has been vanished in Japan, but only 30 percents in Korea is crematory. This burial customs being much stiff existent in Korea, the effect of the population decrease caused by the death is reduced. A case study through questionnaire on the residential preference patterns for the aged over 50 years old shows that Japanese than Korean are more dependent on their sons and daughters, and ‘loneliness of solitary life’is the first reason in both countries. The degree of care for the future life is also remarkably higher in Japanese than in Korean. These are related in various ways to their ages, scholarships and local areas(si or gun). A general cognition in which the shortage of labour forces comes into existence in aged society is of misconception, because it comes from taking labour forces away from the aged, not from being old society. Even a minute population change is worth notice since the inertia law is also applied to the population phenomenon. Malthusinism hold fairly good even now, and the notion is very important in which population, resources and environmental problems are no longer personal or a regional matters, but the global family's issues.

본 연구(硏究)는 선물거래의 선진국이라고 할 수 있는 미국(美國), 영국(英國), 일본(日本)등을 대상으로 선물계약(先物契約)의 증거금변경(證據金變更)이 시장활동(市場活動) 즉 거래량(去來量), 미결제포지션(open interest), 가격변동성(價格變動性)에 미치는 영향(影響)을 만기별(滿期別)로 구분하고 또한 시계열(時系列) 현상(現狀)을 제거한 후 비교분석(比較分析)함으로써 이러한 분석결과를 토대로 우리나라가 주가지수선물을 도입하는데 있어서 차후의 증거금관리(證據金管理)에 대한 하나의 정책적(政策的) 방향(方向)을 제시(提示)하고자 하였다. 연구결과(硏究結果)를 요약(要約)하면 증거금(證據金)은 시장활동(市場活動)인 거래량(去來量)과 선물계약(先物契約)의 수요(需要) 즉 미결제포지션에는 상당한 영향(影響)을 미치나 가격변동(價格變動)에 미치는 영향은 미약하며 그러한 효과는 비교적 단기적(短期的)인 것으로 밝혀졌다. 아울러 그러한 효과는 국가간(國家間) 및 상품간(商品間)에 큰 차이 없이 거의 공통적(共通的)인 현상(現狀)임이 밝혀졌다. 구체적으로 본 연구가 시사하는 바는 연구결과(硏究結果) 중 증거금변경(證據金變更)에 따른 미결제포지션의 움직임을 거래량(去來量)과 연관(聯關)시켜 생각해 볼 때 증거금인하시(證據金引下時) 단기에 거래량이 유의적으로 증가하면서 동시에 미결제포지션이 유의적으로 증가하는 것으로 보아 증가되는 많은 거래량은 선물시장 참여자들이 새로운 포지션을 취하기 때문인 것으로 보여진다. 이러한 사실은 거래소가 증거금인하(證據金引下)를 통하여 잠재적인 시장참여자들의 비용(費用)을 낮춤으로써 시장유동성(市場流動性) 제고(提高)를 유도하는 경우 이러한 시도는 단기적(短期的)으로는 어느 정도 효과(效果)를 거둘 수 있음을 시준(示晙) 한다. 또한 증거금변경이 가격변동성(價格變動性)에 미치는 영향은 크지 않은 것으로 밝혀져 일반적으로 선물거래소들이 취하고 있는 증거금정책으로써 가격변동성을 관리하기 위한 증거금(證據金) 운용정책(運用政策)은 적어도 단기에 있어서는 어느 정도 효과를 보나 그 효과는 크지 않은 것으로 판단된다. 이러한 사실들은 증거금변경이 이루어지는 시점이 일반적으로 시장활동(市場活動)의 변화(變化)가 나타나기 시작한 후 1개윌 이내에 이루어져 왔다는 사실을 고려한다면 많은 선물거래소들이 취하고 있는 증거금관리정책은 비교적 단기적인 효과를 위한 것이며 그러한 정책(政策)들은 나름대로 소기의 목적(目的)으로 달성하고 있는 것으로 보인다. 끝으로 증거금변경이 선물시장활동에 미치는 효과의 국가간(國家間)의 차이(差異)가 없고 또한 상품간(商品間)에도 사실상 차이(差異)가 없다는 사실은 앞으로 선물시장을 개설할 우리나라의 입장에서 볼 때 선물증거금(先物證據金) 운용(運用)에 관한 정책수립시(政策樹立時) 금융선진국(金融先進國)의 증거금(證據金) 정책운용(政策運用)을 통한 시장관리(市場管理) 경험(經驗)을 어느 정도 참고할 수 있음을 시사한다고 할 것이다.

This study aims to illustrate the essence of meaning through sexual minorities' participant experiences in a sexual minority community. This research intends to explore essential meaning structure revealed in sexual minorities' reasons for joining a sexual minority community and in their experience in community activities. The study participants were 8 sexual minorities, and data was collected by in-depth interview. Data analysis was described using Giorgi's analysis methodology in phenomenological research method. As a result, the sexual minorities' participation was consisted of 13 meaning units, 6 derived topics, and 3 essential topics, which were 'An unquenchable thirst', 'Another world called oasis', and 'Real estrangement' Moreover, based on the essential topics, the study participants' common meaning of essence was analyzed as 'spiritual diaspora'. Sexual minority communities shall contribute to developments of own organizations through mutual compensations by vitalizing exchanges with other communities based on this study. Also, the communities should the variety in sexual minorities to allow various people's participation. People's awareness on sexual minorities must be transformed so that closed communities can change. Comprehensive knowledge on sexual minorities should be distributed in the social welfare fields so that sexual minorities may search solutions on issues through various access not limited to certain communities.

Sedimentation is a common problem for river ports. But its intensity depends on the rate of sedimentation, channel shape and size, hydrodynamic behavior of the river and the importance of the port. High sedimentation rate in Yangon River has become one major issue for Myanmar as her largest port is located on the Yangon riverbank. As a result of the high sedimentation rate, shallow water area near the confluence of Yangon River, Pazundaung Creek, and Bago River keeps blocking the navigation channel to the Yangon Port, which also limits the size of vessel calling to Yangon Port. Therefore, studies to understand sediment transport process in Yangon River are required because the economic development of Myanmar highly relies on the Yangon Port. This paper aims to calculate the sediment transport and to predict the riverbed elevation changes in Yangon River by using Bagnold (1966) theory. Calculation result shows that huge difference can be found in the bed load transport between the rainy season and dry season in Yangon River, and thus the sedimentation problem would become more severe in the dry season when the transported sediments are reduced. The estimated sedimentation rate in dry season indicates that the rate of riverbed level rise near the Yangon Port area is about 0.063 m per year, which would lead to approximately 3.15 m rise in the riverbed level in next 50 yrs, considering the same workload of dredging to maintain the navigation channel.
