본 연구는 주택가격의 변화가 우리나라 지방은행의 경영성과에 미치는 영향을 DOLS 모형을 이용하여 분석하였다. 분석 결과, 주택가격변동률은 지방은행의 성장성, 수익성 및 건전성에 모두 통계적으로 유의한 영향을 미치지 못하는 것으로 나타났다. 거시경제변수 중에서 단기금리만이 어떠한 모형에서도 유의한 양(+)의 영향을 미치는 것으로 나타났다. 이는 단기금리가 상승하면 지방은행이 대출을 유의하게 증가시키고 이는 수익성의 유의한 증가를 가져오지만 건전성에는 유의한 부정적 영향을 미치는 것을 의미한다. 반면에 은행특성변수들은 대부분 지방은행의 성장성, 수익성 및 건전성에 유의한 음(-)의 영향을 미치는 것으로 나타났다.

본 연구는 하수오니의 농경지 이용 가능성을 밝히고자 중랑, 가좌, 나주 및 용인 하수 종말 처리장에서 채취한 하수오니를 처리한 토양에서 옥수수와 배추를 재배하여 생육 및 토양의 화학성 변화에 미치는 영향을 검토하였다. 옥수수의 생육조사결과 오니 처리율이 증가할수록 초기 생육이 저조하였다. 배추의 생육 조사 결과 초기 3주간은 12.5 및 $25Mg\;ha^{-1}$ 처리구가 좋은 생육을 보였고 후기에는 50및 $100Mg\;ha^{-1}$처리구의 생육이 더 좋은 결과를 나타내었다. 그러나 최대 생장을 보인 처리구도 화학비료 시용구에서의 생육에는 미치지 못했다. 양이온치환용량, 유기물 및 질소의 경우는 처리간의 차이는 뚜렷하였지만 재배 전후에는 큰 차이가 없었다. Na, K, Ca, Mg 등의 염기류들도 비슷한 경향을 보였다. 토양포화침출액의 EC는 재배 전과 비교하여 재배후에 감소하였고 오니처리량이 많을수록 감소폭이 커서 재배전보다 오니 처리량 간의 차이가 줄었으나 유료인산 함량은 재배중 뚜렷한 증가 경향이 나타났다. 따라서 오니시용기준은 질소가 아닌 인산을 기준으로 하여 처리량을 결정하며 부족분은 화학비료로 보충하도록 하는 것이 바람직한 것으로 사료된다.

This study investigated growth and hematological changes in parrotfish Oplegnathus fasciatus (~200 g/fish) reared under different total ammonia nitrogen (TAN) concentrations (0, 4, or 8 mg/L) for 6 weeks. Survival rates of parrotfish in all experimental groups did not significantly differ, as they were all ~100%. Although specific growth rate (SGR), weight gain, and daily feed intake in the high TAN concentration group (TAN8) were significantly lower than in the other two groups, there was no significant difference between the TAN4 group and the control group, (TAN0), indicating that parrotfish have a strong resistance to ammonia toxicity. As for temporal changes of the major blood components, cortisol increased as a result of stress caused by the high ammonia concentration in the TAN8 group. For this reason, the concentrations of energy sources such as glucose and total cholesterol were reduced. However, there was little difference among all experimental groups in concentrations of liver function glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT), and nutrient factors, such as total protein and albumin.

Objectives: Socioeconomic factors are one of the significant factors explaining drinking problems in our society. From the poverty and inequality perspective, not only absolute poverty but perceived level of poverty or inequality has a direct effect on one's health and health behaviors. The purpose of the study is to explore the growth trajectories of problem drinking in Korea in relation to poverty and perceived income. Methods: Data from 13,414 adults were analyzed using 4 years of data (2010 to 2014) from the Korea Welfare Panel. Main variables included poverty status, perceived income inequality, and problem drinking. A latent growth modeling was employed for the analysis. Results: The non-poverty group had higher initial level of problem drinking; however, the poverty group showed higher rate of increase in problem drinking rate. The perceived income inequality had no significant influence on the initial level, but over time, those with higher level of perceived income inequality showed higher rate of increase in problem drinking. Conclusions: Findings showed that poverty and inequality affect changes in problem drinking. Efforts to prevent and decrease problems related to alcohol should not only focus on changing individuals' behavior but also on decreasing the inequality gap.

Prader-Willi syndrome (PWS) is a genetic disorder that is considered, especially on child, to cause poor feeding, hypotonia, failure to thrive, developmental delay and hypogonadism which is known to affect between 1 in 10,000 and 30,000 people. The children with PWS are viewed as affected by growth hormone (GH) insufficiency, although the exact mechanisms of GH deficiency are not fully understood. However, the benefits of GH treatment in children with PWS are well established. Myers, et al. (2006), Grugni, et al. (2016) indicated its positive effects on linear growth, body composition, motor function, respiratory function and psychomotor development. Despite of its effectiveness and advantages had been well known and proven in many other studies, there is only one recombinant GH product that is approved for PWS in Korea, $Genotropin^{(R)}$, till now. A phase III clinical study of GH treatment with $Eutropin^{TM}$, in 34 Korean PWS children is in progress, which is expected to have comparable effects and safety profile with the active control by assessing auxological changes such as height standard deviation score, body composition changes such as lean body mass and percent body fat, motor and cognitive development using Bayley scale, and safety profiles.

This study examined the effects of different photoperiod conditions on olive flounder (Paralichthys olivaceus), a commercially important species in Korea. Daily variations in the expression of mRNA for the growth-related genes arylalkylamine N-acetyltransferase2 (AANAT2), preprosomatostatin1 (PSS1), and growth hormone (GH) were examined under a 12 h light:12 h dark photoperiod. All the genes were expressed at higher level during the dark period. Melatonin injections increased the expression of GH, but did not significantly affect the expression of PSS. Under short-day conditions (10 h:14 h), the fish gained more weight than under long-day conditions (14 h:10 h). A long nighttime induced melatonin secretion and increased the expression of GH mRNA, promoting weight gain in this species. Therefore, we thought that the long day condition in raising olive flounder may be effective in inducing body growth.

A comparison was made of population of the economically important cockle Anadara (=Scapharca) broughtoni (Bivalvia, Arcidae) inhabiting different areas of the Razdolnaya River estuary at the head of Amurskii Bay (Peter the Great Gulf, East Sea). Also, changes in cockle population density and structure, as well as in cockle growth rates during the last 20 years were studied. In all years of investigation, the morphometrical parameters and growth rates of cockles were smaller at the sites located close to the River mouth than farther down-estuary. The differences can be attributed to higher concentration of suspended particulate matter, decreased salinity and water temperature, as well as a longer exposure to these unfavorable environmental factors at sites located close to the River mouth, compared to farther sites. For two decades, cockle population density had decreased by almost 30 times at some sites in the River estuary. The main reason for this population decline is commercial over-fishing of the cockle. Besides, for the last 20 years, linear parameters of the cockles in the population decreased approximately by 30% and weight parameters, almost two times. Cockle growth rates also decreased for this period. Evidently, these facts are due to the damaging effect of dredging.

In this paper, using the recently introduced analytical approach for the analysis of mass and heat transfer during film growth in reactors for epitaxy from the gas phase, these processes are analyzed taking into account natural convection and the possibility of changing the rate of chemical interaction between reagents. As a result of the analysis, the conditions under which the homogeneity of the grown epitaxial layers increases with a change in the values of the parameters of the growth process are formulated.
