Most of the important stone cultural heritage (National treasures and Treasures) in Korea are mainly located outdoor and considerably affected by the changes of the temperature, humidity and rainfalls. 541 of the stone cultural heritage are preserved as National treasure and Treasure. The pagodas occupy 187 remains and next 127 Buddha statues, 68 monuments, 60 stupas, and the others 74 stone cultural heritages. The shelter has been installed for one pagoda, 60 Buddha statues, 36 monuments and two stupas. The shelters are categorized in three shapes as traditional shape, modern shape, and others (tradition+modern). Approximately 100 of shelters that have constructed in traditional ways, and about nine of shelters have modern ways, and the only one has the combination shape of tradition and modern, which has been constructed since mid 1900s and repaired from the 1980s~2000s. Many researchers are studying for improvement of manners such as repairing, remodeling or removing of the shelter because problems have occured on shelters. Architectural form of traditional style of Korean timber building is respected, but it has problems on importing natural sunlight to the inside as well as ventilation and spacial problems. However, it needs to supplement policies to improve the positive roles of shelters such as prevention of artificial damage, blocking acid rain, and so on. For instance, the rock-carved Buddha Triad in Seosan, it had problems with viewing, contamination, and dew condensation on the surface. These problems decreased after dismantling the shelter, the space was made for improvement of viewing and dew condensation, and moisture problems were in better conditions. The velocity wind is an important factor in drying conditions on the surface of the rock, therefore the condition has improved after dismantling the shelter.

We report plasma-assisted molecular beam epitaxy of $In_XGa_{1-X}N$ films on c-plane sapphire substrates. Prior to the growth of $In_XGa_{1-X}N$ films, GaN film was grown on the nitride c-plane sapphire substrate by two-dimensional (2D) growth mode. For the growth of GaN, Ga flux of $3.7{\times}10^{-8}$ torr as a beam equivalent pressure (BEP) and a plasma power of 150 W with a nitrogen flow rate of 0.76 sccm were fixed. The growth of 2D GaN growth was confirmed by $in-situ$ reflection high-energy electron diffraction (RHEED) by observing a streaky RHEED pattern with a strong specular spot. InN films showed lower growth rates even with the same growth conditions (same growth temperature, same plasma condition, and same BEP value of III element) than those of GaN films. It was observed that the growth rate of GaN is 1.7 times higher than that of InN, which is probably caused by the higher vapor pressure of In. For the growth of $In_xGa_{1-x}N$ films with different In compositions, total III-element flux (Ga plus In BEPs) was set to $3.7{\times}10^{-8}$ torr, which was the BEP value for the 2D growth of GaN. The In compositions of the $In_xGa_{1-x}N$ films were determined to be 28, 41, 45, and 53% based on the peak position of (0002) reflection in x-ray ${\theta}-2{\theta}$ measurements. The growth of $In_xGa_{1-x}N$ films did not show a streaky RHEED pattern but showed spotty patterns with weak streaky lines. This means that the net sticking coefficients of In and Ga, considered based on the growth rates of GaN and InN, are not the only factor governing the growth mode; another factor such as migration velocity should be considered. The sample with an In composition of 41% showed the lowest full width at half maximum value of 0.20 degree from the x-ray (0002) omega rocking curve measurements and the lowest root mean square roughness value of 0.71 nm.

Quality characteristics of Shiitake mushroom using two types of dryers, energy-efficient heat pump hotair dryer and electric heater hot-air dryer were compared. Energy consumed during drying by heat pump hot-air dryer and electric heater hot-air dryer were 22.8 kWh and 28.9 kWh, respectively. Total polyphenol content of heat pump hot-air dryer and electric heater hot-air dryer after drying were 290.55±10.56 ppm and 192.99±6.53 ppm, respectively. No differences were observed between dryers in reconstitution rate and browning ratio after drying. Also, there were no differences between dryers in color value and ΔE value after drying. Shiitake mushroom drying at 45℃ by heat pump hot-air dryer was proved to be more efficient in energy consumption than by electric heater hot-air dryer.

The alcohol fermentation of apple juice was optimized as a preliminary study for the production of natural apple cider vinegar. To gain an optimal fermentation yield, a central composite design was used to investigate the effects of the independent variables [initial Brix (12/14/16/18/20, X1), fermentation time(48/54/60/66/72h, X2), and fermentation temperature(24/26/28/30/32℃, X3)] on the dependent variables (alcohol content, reducing sugar, Brix, acidity). The alcohol content was 3.4-6.4%, the reducing sugar was 1.93-6.24%, and the Brix was 6.1-13.8°. The alcohol content was mainly affected by the fermentation temperature and increased along with the fermentation time and temperature. The amount of the reducing sugar was significantly affected by the initial Brix and fermentation temperature. The optimal conditions for the alcohol content were found to be 15.22 initial Brix, 64.97 h fermentation time, and 31.56℃ temperature.

In this study, a compositional analysis method was developed that can determine the mixing ratio of poly(ethylene-co-vinyl acetate) (EVA)/low density polyethylene (LDPE) blend using the selective dissolution properties of cyclohexane solvent and also determine the vinyl acetate (VA) content of dissolved EVA using ¹H NMR spectroscopy. As a result of applying this analysis method to EVA/LDPE mixture and blend samples prepared in various ratios, the weight ratio of the separated soluble and insoluble parts was obtained at the level of 97-109% of the EVA and LDPE mixing ratio. Compared to the VA content of EVA used for formulation, the VA content of soluble part was calculated with an average difference of 0.6 and 1.9 wt% in the mixture and blend samples, respectively. These results confirmed that the method of applying the selective dissolution and 1H NMR spectroscopy together is suitable for the composition analysis of the EVA/LDPE blend.

웹의 크기가 폭발적으로 증가함에 따라 인터넷에서 정보를 얻는 수단으로서 검색 엔진의 중요성이 부각되고 있다. 검색 엔진은 사용자에게 최신의 정보를 검색 결과로서 제공하기 위해 웹 페이지를 주기적으로 수집하고 이를 데이타베이스에 저장한다. 웹 크롤러는 이러한 목적으로 웹 페이지를 수집하는 프로그램이다. 대부분의 검색 엔진은 제한된 시간 내에 많은 수의 웹 페이지를 수집하기 위해 다수의 머신을 사용하는 병렬 웹 크롤러를 이용한다. 그러나, 병렬 웹 크롤러의 아키텍처와 세부 구현 방법이 잘 알려져 있지 않기 때문에 실제로 병렬 웹 크롤러를 구현하는 데에 어려움이 많다. 본 논문에서는 병렬 웹 크롤러(parallel web crawler)의 아키텍처와 세부 구현 방법을 제시한다. 병렬웹 크롤러는 다수의 머신에서 웹 페이지를 병렬적으로 수집하기 위해 조정자(coordinator) 대리자(agent) 구조의 2-티어(tier) 모델을 사용한다. 조정자/대리자 모델은 각 머신에서 웹 페이지를 수집하기 위한 다수의 대리자들과 이 대리자들을 관리하기 위한 하나의 조정자로 구성된다. 병렬 웹 크롤러는 웹 페이지를 수집하기 위한 크롤링(crawling) 모듈, 수집한 웹 페이지를 데이타베이스 로딩 포맷으로 변환하기 위한 컨버팅(converting) 모듈, 수집된 웹 페이지의 중요도를 계산하기 위한 랭킹(ranking) 모듈로 구성된다. 본 논문에서는 병렬 웹 크롤러의 각 모듈들을 설명하고, 세부 구현 방법을 설명한다. 마지막으로, 실험을 통해 병렬 웹 크롤러의 성능을 평가하였다. 실험 결과, 제안된 병렬 웹 크롤러가 수집해야할 웹 페이지 개수와 머신 개수에 따라 확장 가능함을 보였다. As the size of the web is growing explosively, search engines are becoming increasingly important as the primary means to retrieve information from the Internet. A search engine periodically downloads web pages and stores them in the database to provide readers with up-to-date search results. The web crawler is a program that downloads and stores web pages for this purpose. A large-scale search engines uses a parallel web crawler to retrieve the collection of web pages maximizing the download rate. However, the service architecture or experimental analysis of parallel web crawlers has not been fully discussed in the literature. In this paper, we propose an architecture of the parallel web crawler and discuss implementation issues in detail. The proposed parallel web crawler is based on the coordinator/agent model using multiple machines to download web pages in parallel. The coordinator/agent model consists of multiple agent machines to collect web pages and a single coordinator machine to manage them. The parallel web crawler consists of three components: a crawling module for collecting web pages, a converting module for transforming the web pages into a database-friendly format, a ranking module for rating web pages based on their relative importance. We explain each component of the parallel web crawler and implementation methods in detail. Finally, we conduct extensive experiments to analyze the effectiveness of the parallel web crawler. The experimental results clarify the merit of our architecture in that the proposed parallel web crawler is scalable to the number of web pages to crawl and the number of machines used.

Purpose: This study aimed to investigate the effects of an encouraging group therapy program on male baby boomers' self-esteem, depression, suicidal ideation, and social interest. Methods: The recruited participants were 33 male baby boomers in G city. The study was conducted from April 4 to June 10, 2016 To test the effects of the encouraging group therapy program, the participants were divided into two groups: an experimental group (N=15) and a control group (N=18). The data were analyzed using the x² test, t-test, and Fisher exact test with the SPSS/WIN 22.0 program. Results: Compared to the control group, the experimental group showed significantly increased scores for self-esteem (t=2.40, p=.023) and social interest (t=2.21, p=.040) along with a significant decrease in the depression score (t=-3.39, p=.002); however, the suicidal ideation score was not significantly decreased (t=-0.43, p=.673). Conclusion: The findings from this study indicate that an encouraging group therapy program effectively enhances self-esteem and social interest while reducing depression in male baby boomers. Therefore, this program represents a good strategy that community mental health nurses can use to improve psychiatric health among male baby boomers.

The purpose of this study is to understand the impact of National Assessment of Educational Achievement on the class management and to understand the vivid on-sight education arena from the perspective of home room teachers by investigating the actual conditions of on-sight class management and the awareness of 6th grade teachers of the effect of National Assessment of Educational Achievement on the class management of 6th grade elementary school classes, which has been enforced since 2008. The results of this study can be summarized as follows. The 6th grade home room teachers showed strong tendency of managing their classes with emphasis on a course of study due to pressure from the local education office, the school, and the administrators regarding National Assessment of Educational Achievement. In the aspect of school life guidance, there was little time left for it as too much attention was being given to study guidance, and even if school life guidance was being done, interest was focused on the students` grades, and caused problems in the students` school life by not being able to grasp the students` worries or troubles. In the aspect of human relations centered on the home room teachers, cooperative relationship for class managements was maintained among the 6th grade home room teachers who were in similar environments, who felt pressure from the administrators that emphasized study guidance with interest in the results of the National Assessment of Educational Achievement, but it was not with indifferent fellow teachers who were in charge of other graders.
