본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

Objectives The purpose of this study is to analyze how to hold a pencil in the first grade of elementary school Korean and to find ways to help students write correctly. Methods A case study method was used among the qualitative studies, and interviews with Yoo Sang-eon for a single case of how to hold a pencil, Hangul files related to his claims, YouTube materials, student handwriting materials, and testimonials were used in this study. Textbooks and teacher s guides were analyzed in a multi-layered manner, along with texts and letters. Results As a result, it was found that there was a problem with the position of the finger guiding in the current 2015 revised curriculum for the first grade textbook. In other words, if you look at the position of your fingers when writing, holding a pencil while holding your thumb and index finger in a circle is not the optimal way. Also, it is not appropriate to place your elbows on the desk when writing, so it is a guideline that needs to be corrected. On the other hand, Yoo Sang-eon s method of holding a pencil is a better way to help students write correctly. Here s how to hold a pencil correctly, as he suggests. First, put the tip of the thumb and middle finger together to make a round shape, and then place the pencil on the nail area of the middle finger and the area next to the bone where the index finger begins. Second, lift your thumb upwards, bend it at a right angle, and press the pencil gently from above. Third, bend the forefinger close to a right angle and put it lightly between the thumb and middle finger without straining. Fourth, write in such a way that the wrist or arm where you are writing extends slightly over the edge of the desk. Conclusions If you write according to the shape and position of the finger holding the pencil as suggested by Yoo Sang-eon, the force of the finger applied to the pencil is maintained evenly, so that you can write more correctly. 목적 이 연구의 목적은 초등국어 1학년의 연필 잡는 법을 분석하고, 학생들이 바른 글씨를 쓰도록 돕는 방안을 모색하는 데 있다. 방법 이 연구에서는 질적 연구 가운데 사례 연구라는 연구 방법을 사용하였고, 유상언의 연필 잡는 법이라는 단일 사례를 대상으로 그와의 인터뷰 자료와 그가 주장하는 내용과 관련한 한글 파일, 유튜브 자료, 학생들의 글씨 자료, 소감문이나 편지글 등과 함께 교과서와 교사용지도서를 다층적으로 분석하였다. 결과 그 결과 현행 2015 개정 교육과정 1학년 교과서에서 안내하고 있는 손가락의 위치에 문제가 있다는 것을 발견하였다. 즉, 글씨를 쓸 때 손가락의 위치를 보면, 엄지와 검지를 둥그렇게 모으면서 연필을 잡는 방법은 최적의 방법이 아니라는 것이다. 그리고 글씨를 쓸 때 팔꿈치를 책상 위에 올리도록 한 것도 적절하지 못해서 수정해야 할 지침이다. 이와 달리 유상언이 제안하는 연필을 바르게 잡는 방법은 학생들이 글씨를 바르게 쓰는 데 도움을 주는 더 나은 방법이다. 그가 제안하는 연필을 바르게 잡는 방법은 다음과 같다. 첫째, 엄지손가락과 가운뎃손가락 끝을 맞잡아 둥글게 만든 후 가운뎃손가락의 손톱 부위와 집게손가락이 시작되는 뼈 옆 부위에 연필을 올린다. 둘째, 엄지손가락을 위로 들어서 직각으로 꺾은 후 연필을 위에서 지그시 눌러 준다. 셋째, 집게손가락도 직각 가깝게 꺾어서 엄지와 가운뎃손가락의 사이에 힘주지 않고 살짝 붙여만 준다. 넷째, 글씨 쓰는 손목이나 팔이 책상 모서리에 약간 걸치는 정도로 해서 글씨를 쓴다. 결론 유상언이 제안하는 연필 잡는 손가락의 모양과 위치에 따라 글씨를 쓰면, 연필에 가해지는 손가락의 힘이 균등하게 유지되어 편안한 자세로 글씨를 더 바르고 쉽게 쓸 수 있다.

Purpose - Media is a significant distributional channel in sport. In terms of determining the influencer in building sport media contents, recent sport media studies have employed agenda-setting theory, assuming media itself as the agenda provider. In a real-world situation, however, sports stars have been deemed key factor determining distribution contents in sport. The starting point of this study is the “tacit premise” of agenda-setting theory. Given the agenda-setting theory, the current study attempted to explore the function of sport stars as an agenda provider, which is a key determinant of sport distribution. Research design, data, and methodology – This study has reviewed articles of Yuna Kim, Sang-hwa Lee, and Hyun-jin Ryu from daily newspapers including as dong-a ilbo and joongang ilbo (2013 to 2017). The study collected data, portable document format (PDF), from the online archive of dong-a ilbo and joongang ilbo. We coded the length of the article, the frequency, the size of the picture, and the structural form of the article. Inter-coder reliability was compared with data previously investigated by the researcher. Inter-coder reliabilities for study 1 and 2 was .89 and .85. To examine hypotheses, descriptive analysis, correlations, and cross-tap analysis were performed. Results – The results partially supported the hypotheses proposing the significant role of sports stars as the agenda setters in distributing sport media contents. In specific, the study found that the number of articles about sports stars prevailed the number of articles about regular athletes. Besides, studies found that the use of photos was more frequent in articles of sports starts than that of regular athletes. In sports newspaper articles, featured story articles were used more than straight-articles for news relating to sports stars. Also, sports newspaper of sports stars contained more information associated within an event rather than outside of an event. Conclusions – In sports journalism, this study challenges the current theory that the media affects the composition and the content of sports coverages. As the principle of the agenda-setting of sports media, the influence of sports stars must be continuously studied along with a follow-up study.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

This study was designed to investigate the effects of a 6-week progressive exercise, mainly calisthenics, and education for low back pain on muscular endurance, flexibility, and self-perceived pain in low back patients. Eighteen female patients, aged 48±6.84 years, were volunteered to participate in the study as subjects. Standing height, body weight, percent body fat, waist-hip ratio(WHR), sit-and-reach trunk extension, sit-up, back sit-up, and pain ratings were measured in pre test. Upon the completion of the pre test, they went through the six weeks of interventions composed of progressive exercise and education for the first four weeks and the exercise only for the last two weeks. Then, they were tested in the post test by the same manner as the pre test. The results of pre and post test were compared by the paired t-test. The main results of the present study were as fellows: First, there were no significant changes by the interventions in body weight and WHR, whereas percent body fat were reduced significantly by the interventions. Second, flexibility and muscular endurance were enhanced significantly by the interventions. Third, self-perceived low back pain ratings and perceive ratings of pain in the daily activities were reduced significantly by the six weeks of interventions. It was concluded that low back pain would be relieved by the progressive exercise and education for low back pain, and that the interventions would be helpful to prevent additional injuries by increasing the flexibility and muscular endurance.
