Residence time is defined as the time taken for a material in a system to leave the system. The residence time characteristics in shellfish aquaculture determine the dispersion of excretion from aquaculture farms, along with the supply of food by seawater exchange. In this study, we estimated the spatial distribution of average residence time in the shellfish farming area using a particle tracking model. As a result, a relatively short average residence time of about 20 days or less was calculated in most areas, but an average residence time of more than 40 days was calculated in the inner areas. Relatively long average residence times were calculated along the west coast compared to the east coast, with the longest average residence time of more than 50 days in the northwestern areas. It can be inferred that the disturbance of the benthic ecosystem caused by shellfish farms is likely to be large because of the relatively weak dispersion of excrement from shellfish farms located on the west coast, especially in the northwest region. This distribution of average residence time is important for understanding the potential effects of seawater exchange on the environmental sustainability of shellfish farms, along with the seawater circulation characteristics of Jaran Bay.

A new building with total floor area of 3,000㎡ or above, which public agency currently constructs, is required to obtain a building energy efficiency rating level 1 or better. Although construction cost is caused to increase as building energy efficiency increases, precise standards for construction cost according to each rating level are not established. Some studies presented a difference in construction cost according to rating, based on the estimated construction cost of single building. However, analysis of construction cost based on actual construction cost according to each rating level is still insufficient. Therefore, this study presents a difference in actual construction cost according to building energy efficiency rating for non-residential building. To this end, first, data on the actual construction cost of non-residential building obtaining level 1+, 1++ in main certification were collected through survey. Second, outliers were removed by Interquartile Ranges. Third, total construction costs according to building energy efficiency rating were comparatively analyzed. As a result, the analysis showed that level 1++ additionally needed approximately 37% of construction cost of office building, compared with level 1+, and the difference was statistically significant.

To achieve the reduction target of GHG emission from the building sector, the government introduced the Zero Energy Building certification system in 2017 according to the Green Building Promotion Act, and established the roadmap for the expansion of the obligation to private buildings in 2025. With the expansion of obligatory buildings, it is necessary to find the affecting factors for certification and data about quantified performance levels. However, in the early times of the system, there were not many certified buildings. Therefore, this study tried to analyze the performance levels of the educational research facilities which had more than grade 1 in the latest 2 years in Building Energy Efficiency Rating as one of Zero Energy Building certification standards, and to suggest the influencing factors on zero energy building design and quantified performance levels. In a statistical analysis method, this study determined the affecting factors on energy requirement, and analyzed the actually certified buildings in order to find grade-based performance levels of the certified in building energy efficiency rating. According to the multiple regression analysis on the affecting factors on design, a coefficient of determination was 0.778 which was significant. Regarding most influencing factors on design, the higher grade, the better performance.

The concepts of residence time and flushing time can be used to explain the exchange and transport of water or materials in a coastal sea. The application of these transport time scales are widespread in biological, hydrological, and geochemical studies. The water quality of the system crucially depends on the residence time and flushing time of a particle in the system. In this study, the residence and flushing time in Gamak Bay were calculated using the numerical model, EFDC, which includes a particle tracking module. The average residence time was 55 days in the inner bay, and the flushing time for Gamak Bay was about 44.8 days, according to the simulation. This means that it takes about 2 months for land and aquaculture generated particles to be transported out of Gamak Bay, which can lead to substances accumulating in the bay. These results show the relationships between the transport time scale and physical the properties of the embayment. The findings of this study will improves understanding of the water and material transport processes in Gamak Bay and will be important when assessing the potential impact of coastal development on water quality conditions.

본 연구는 자기표현 안하는 아동에 대한 상담사례 연구이다. 아동에게 매회기 30분씩 총35회의 놀이 활동을 통한 상담으로 실시되었다. 총35회의 상담이 진행되었고 종료 후 1회의 추후상담이 있었다. 아동은 주로 게임을 통하여 자신을 표현하고 자신감을 얻었다. 어머니 상담에서는 부부관계에 대한 자세한 내용은 생략했으며 주로 아동과 관련된 부분만 요약 정리하였다. 2016년 11월 첫째 주부터 2017년 4월 셋째 주까지 총6개월 동안 주1회 매주 금요일 진행하였다. 아동이 자기표현의 올바른 방법을 이해하고 익혀서 바람직한 대인관계를 갖고 사회적으로 원만하게 생활할 수 있도록 게임을 통한 놀이상담으로 진행 되었다. 초기상담 과정에서 아동은 무표정하고 나무토막같이 경직되어 보이는 등 감정이 얼어붙은 상태였다. 언어표현이 좋아지게 되면서 집안에서 일어난 일들 이라는 치료게임을 소개하였다. 이 게임을 통하여 아동은 자신의 감정을 언어로 잘 표현 하였다. 게임에서도 승부에 집착하던 모습에서 점차적으로 게임 그 자체를 즐기는 생산적인 모습으로 변화하였다. 종결하는 시점에서 아동은 지능이 높은 것만큼 표현도 조리 있게 잘 하고 있다. 아동이 한참 표현하는 단계에서 자기 조절하는 것이 부족한 채 종결하게 되는 것이 아닌가 하는 우려도 있다. 하지만 엄마가 지금까지 해온 것을 바탕으로 하여 노력을 한다면 잘 극복할 수 있으리라고 믿고 종결한다. 따라서 앞으로는 가족 간에 얼마나 건강하게 잘 화합하며 지낼 수 있는 가가 과제로 남아있다. This study is a case study of counseling for children who do not express themselves. It was conducted with a total of 35 play activities in 30 minutes each time. A total of 35 counseling sessions were held and one counseling session was held at the end of the session. Children mainly express themselves and gain confidence through games. In the mother counseling, the details of the marital relationship were omitted and only the part related to the child was summarized. From the first week of November, 2016 to the third week of April, we conducted a weekly Friday every week for a total of six months. In the initial counseling process, children were asked to express their feelings as if they were expressionless and stiff like a piece of wood, so that they could understand the correct way of self-expression and have a good interpersonal relationship, It was in a frozen state. As the language expression improved, I introduced a treatment game called what happened in the house. Through this game, children expressed their feelings in language well. It gradually changed from a state of being obsessed with the game to a productive state enjoying the game itself. At the end of the term, the child is well represented with as much intelligence as possible. There is also concern that the child may end up lacking self-control at the stage of expression. However, based on what my mother has done so far, I believe that I can overcome my efforts and conclude. In the future, how well the family can stay together in the future remains a challenge.

Background/Aims: To evaluate the technical feasibility of stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC) with the major portal vein tumor thrombosis (PVTT). Methods: Ten institutions affiliated with the Korean Stereotactic Radiosurgery Group were provided the contours of four cases: the first case was the first branch PVTT with sufficient normal liver volume (NLV), the second was the first branch PVTT with insufficient NLV, the third was the main trunk PVTT at confluence level, and the fourth was the main trunk PVTT with entire length. The institutions were asked to make SBRT plans according to their current treatment protocols and to complete facility questionnaires. Results: Based on institutional protocols, SBRT was feasible in nine institutions for the first case (32-60 Gy in 3-5 fractions), in eight institutions for the second case (32-50 Gy in 3-5 fractions), in seven institutions for the third case (35-60 Gy in 3-5 fractions), and in four institutions for the fourth case (35-42 Gy in 4-5 fractions). The other institutions recommended hypo- or conventional fractionation due to insufficient NLV or gastrointestinal organ proximity. With analysis of the SBRT dose to the central hepatobiliary tract, the major PVTT could theoretically be associated with a high risk of hepatobiliary toxicity. Conclusions: Although SBRT is a technically feasible option for HCC with the major PVTT, there was a variability among the participating institutions. Therefore, further studies will be necessary to standardize the practice of SBRT for the major PVTT. (J Liver Cancer 2018;18:130-141)
