Low voltage direct current (LVDC) distribution system is a suitable techno-economic candidate which can create an innovative solution for distribution network development with respect to rural electrification. This research focuses on the use of LVDC distribution system to replace some of KEPCO's existing traditional medium voltage alternating current (MVAC) distribution network for rural electrification in South Korea. Considering the technical and economic risks and benefits involved in such project, a comparative techno-economic analysis on the LVDC and the MVAC distribution networks is conducted using economic assessment method such as the net present value (NPV) on a discounted cash flow (DCF) basis as well as the sensitivity analysis technique. Each would play a role in an economic performance indicator and a measure of uncertainty and risk involved in the project. In this work, a simulation model and a computational tool are concurrently developed and employed to aid the techno-economic analysis, evaluation, and estimation of the various systems efficiency and/or performance.

This note summarizes the application of zooplankton indices for water quality management and estimation based on main research topics of articles focusing on wetland ecosystems, topics that are remained poorly investigated in S. Korea. The aquatic ecosystem-based consists of indices that respond to different target environmental factors, including environmental disturbance. Among the major indicator species and biota, we reviewed that management strategy for the wetland environment has to be focused more on small-sizes, in terms of zooplankton ecology and indices. The ecology of zooplankton communities in freshwater ecosystem has been the focus of an increasing number of studies since 2019, and considerable progress has been made in understanding the major mechanisms involved in regulating their abundance, diversity and spatio-temporal patterns. Even though studies on the freshwater ecosystem in Korea have a long history, a few of studies on zooplankton biota were conducted at wetlands. We suggested the candidate zooplankton indices proposed by the U.S. EPA and EU to suit Korean conditions. In the step of selecting metrics, the best available metrics are species-related variables, such as composition and abundance, as well as richness and diversity. Overall, in spite of several limitations, the development of a plankton-based multivariate assessment method in Korea wetlands is possible using mostly field research data. Later, it could be improved based on qualitative metrics on zooplankton, and with the emergence of further survey data. The present information can be used as basic information for researchers who are dealing with aquatic environments and its interaction with organisms.

This study was examined to establish a conditions for producing Tteokbokki using dry-milling rice flour which can save manpower and labor time. Since the cost of producing rice flour milled in a wet condition is 500 to 700 won/kg, which is more than twice as much as that of 300 won wheat flour, it is necessary to directly make rice flour from raw rice. The dry-milling rice flour used in the experiment was produced by Air mill (Nara machinary co. ltd., Tokyo, Japan) from 5 rice cultivars (Samkwang, Dasan-1, Boramchan, Seolgaeng, Hanareum-2), which were cultivated in A-san in 2015 year. Their particle sizes were 50, 100 and $150{\mu}m$ for each cultivar, respectively. A control was a wet-milled rice flour milled with a roll mill after the rice was soaked in water for 4 hours. The moisture content of dry-milling rice flour based on cultivars was 11 ~ 12%, and added water up to 50~55% of dry-milling rice flour weight. The RVA characteristic of peak viscosity was the highest in Dasan-1 and Hanareum-2, the lowest in Seolgaeng. The setback value used as an indicator of aging was the highest in Dasan-1, therefore Dasan-1 was expected to be quick solidification, resulting in the low tendency of sensory evaluation. The damaged starch was high in Dasan-1 and Boramchan (p<0.05) compared to others. The Hunter color L were no significant among cultivars and b value increased in all cultivars of dry-milling rice flour compared with control. The hardness of dry-milling rice flour was higher than that of the control, especially Dasan-1 and Hanareum-2 were the highest. Based on the sensory evaluation, the best cultivars were Boramchan, Hanareum-2 and Samkwang. The overall preference of dry-milling rice flour was good in particle size of 50~100um.

작물의 스트레스를 탐지하는 것은 생산량 감소를 평가하는데 매우 중요하다. 광화학 반사 지수 (PRI)는 LUE의 원격 감지 지표로서 개발되었으며, 많은 연구자들에 의해 식생의 스트레스 탐지에 효과적으로 사용할 수 있음이 입증되었다. 그러나 원격탐사 영상에 기반한 PRI를 이용한 연구는 매우 드물다. 낮은 분광해상도로 인하여 드론 및 위성영상 기반의 PRI 모니터링이 어렵기 때문이다. 본 연구에서는 다중분광 센서 기반의 PRI를 산정하기 위하여 인접한 밴드를 이용한 융합 방법을 제안하였다. 제안한 기법을 초분광 및 다중분광 영상에 적용한 결과 산출된 PRI는 79%의 설명력을 나타내었으며, 지상고정형 센서의 관측값과도 유사한 변동 특성을 나타내었다. 따라서 밴드 융합에 의한 PRI는 작물 스트레스 평가에 적용이 가능할 것으로 판단된다.

Regulatory sentiment refers to the market's subjective evaluation of regulatory reform and is one of the most widely adopted indicators to those charged with implementing and diagnosing regulatory policies. The use of regulatory sentiment in advanced analysis has become universal, albeit it is often limited due to difficulties in articulating consistent and objective quantitative indicators that can meticulously reflect market sentiment overall. Thus, despite ample effort by scholars to read the economic impact of regulatory sentiment in the real economy, causal links are difficult to spot. To fill this gap in the literature, this study analyzes a regulatory sentiment index and economic performance indicators through a text analysis approach and by inspecting diverse tones in media articles. Using different stages of tests, the paper identifies a causal relationship between regulatory sentiment and actual economic activities as measured by private consumption, facility investment, construction investment, gross domestic investment, and employment. Additionally, as a result of analyzing one-unit impulse of regulatory perception, the initial impact on economic growth and private investment was found to be negligible; this was followed by a positive (+) response, after which it converged to zero. Construction investment showed a positive (+) response initially, which then rapidly changed to a negative (-) response and then converged to zero. Gross domestic investment as the initial effect was negligible after showing a positive (+) reaction. Unfortunately, the facility investment outcome was found to be insignificant in the impulse response test. Nevertheless, it can be concluded that it is necessary and important to increase the sensitivity to regulations to promote the economic effectiveness of regulatory reforms. Thus, instead of dealing with policies with the vague goal of merely improving regulatory sentiment, using regulatory sentiment as an indicator of major policies could be an effective approach.

The age of the very first smoking is a significant indicator of life-long health status. Smoking prevention intervention was actively conducted based in middle and high schools with the support of the Korean Act for Health Promotion since 1998. These governmental supports became large and various smoking prevention programs were developed and conducted in diverse standards and perspectives. This study made a comprehensive descriptive literature review on smoking prevention educational programs for youth in Korea to identify the intervention quality and effectiveness of them for future smoking prevention program development. A total of 28 peer-reviewed journal articles published between May, 1995 and May 2005 (for the last 10 years) were finally included in this review process. The study participants should be adolescences in middle or high schools in Korea and the intervention types of the review studies should be smoking prevention or cessation educational programs. The outcomes of the reviewed studies were reanalyzed by the participants' characteristics, theory basement, evaluation design, intervention period, evaluation outcomes, and program effectiveness Most smoking intervention programs were not specified by sex and smoking status. Largely most intervention programs focused on male students although female students' smoking percent is increasing including both smokers and nonsmokers. Based on the school grades, the large percents of smoking intervention were conducted to the first grade of middle school and the first grade of high school. Almost 70% of the reviewed studies did not apply any health behavior change theories and the Transtheoretical model and social cognitive theory were utilized in 7 studies among the last reviewed 30%. The theory-based intervention studies had greater effectiveness than the non-theory based studies. More than 90% had quasi-experimental evaluation design and the effectiveness of the non-experimental designed study seemed over estimated than the quasi-experimental or experimental designed studies. More than 60% of the reviewed studies made their education for less than j days, over a short period and the evaluation factors were knowledge and attitude in general which can be obtained in short intervention period. Therefore, smoking intervention programs for youth in Korea need to be modified in terms of research design such as the intervention period, intervention-evaluation design, theory-based approach, and population-focused intervention specification.
