박영민, 김의수. 왼팔 보강 트레이닝이 중년여성 골퍼의 비거리 및 정확성에 미치는 영향. 운동과학, 제12권 계3호, 541-550, 2003. 본 연구는 골프를 즐기는 대다수 계층 중 생활의 활력을 찾으려는 중년여성골퍼의 수가 증폭하고 있고, 골프 대중화는 앞당겨지고 있는 데 반해 그들의 골프운동에 대한 인식이나 방법적인 면에서는 몸(신체)의 상태는 고려하지 않고 그릇된 많은 연습량과 볼을 맞추는 데만 급급한 사정을 조금이나마 해소하는 것과 몸의 좌ㆍ우 균형을 맞춘다는 것에 초점을 두었다. 왼쪽 근육보다 오른쪽 근육이 발달한 데서 기인한 문제점들이 몸의 좌ㆍ우 균형을 틀어지게 했고 골프운동에서도 잘못된 운동습관을 만들고 있다. 특히, 전체 스윙 과정 중 백스윙시에 발생되는 오른팔과 어깨 들림, 오른손의 당김 현상이 가장 큰 문제점이라 할 수 있다. 왼팔 백스윙 보강 트레이닝을 중년여성들로 하여금 수행하게 함으로써 골프 드라이버 샷 비거리와 정확성(그린 적중률)에는 어떠한 효과가 있는지를 규명하는 데 본 연구의 목적이 있다. 본 연구의 실험절차는 만 40세 이상인 중년여성 16명을 대상으로 실험집단과 통제집단으로 각각 8명씩 무작위 선정하여 실험집단은 8주 동안 왼팔 백스윙 보강 트레이닝을 수행하게 하였고 통제집단은 기존의 기술적인 연습방법만을 수행하게끔 했다. 실험집단의 전ㆍ후 비거리와 정확성의 차이, 통제집단의 전ㆍ후 비거리와 정확성의 차이를 반복적 측정 t-검증으로 유의한 차이를 알아보았다. 1. 실험집단의 백스윙 보강 트레이닝 수행 전ㆍ후의 비거리 및 정확성은 모두 통계적으로 유의한 차이가 있었다. 2. 통제집단의 기존 연습 방법 수행 전ㆍ후의 비거리 및 정확성에는 유의한 차이가 없었다. 이와 같은 결과들로 볼 때, 왼팔 백스윙 보강 트레이닝의 수행으로 볼의 비거리 및 정확성(그린 적중률)에 미치는 유의한 영향에 있어서는, 중년여성골퍼뿐만이 아니고 나이가 들어서 왼쪽 근력에 비해 오른쪽이 강해 골프의 잘못된 운동수행을 하는 경우에도 왼쪽 백스윙 보강 트레이닝은 경기력에 좋은 영향을 줄 것으로 사료된다. 그리고 앞으로 후속 연구에서는 골프 스윙의 구성 중 상체의 왼팔 백스윙 구간의 보강 트레이닝뿐만 아니라 왼쪽 하체의팔로스루(Follow through)와 피니시(finish) 구간의 보강 트레이닝을 더한다면 좀더 심도있는 연구가 될 것이고, 트레이닝을 통제할 수 있는 보다 많은 피험자를 대상으로 한 조사에서는 좀더 신뢰성 높은 실험연구가 될 것이라 사료된다. Park, Y.M., Kim, E.S. The Influence of Left Back Swing Reinforcement Training on the Distance and Accuracy of Middle-aged Women. Exercise Science, 12(3): 541-550, 2003. There is the increasing number of middle-aged women golfer, which result from new life style and the recent popularity of golf. In spite of the recent trend, there are little changes regarding the recognition of a golf and the method of golf training. This research has two main focuses. First, the research concentrates on the wrong method of training. For example. most of middle-aged women tend to practice without consideration the balance of a body and only simply hitting balls. Secondly, it's to correct the balance of a body. we mostly use right-hand muscle in many activities such as daily life, labour, playing tennis, playing badminton and so on. Right-hand muscle has been, therefore, developed much more. It results in the unbalance of a body and bad habits on playing golf. Especially, the phenomenon of lifting right arm, shoulder and the phenomenon of drawing right-hand, happening in backswing, are serious problems. When middle-aged women train the left back swing training, the training analyse effect on the distance of drive shot and accuracy. We divided middle-aged women golfers into two groups; a experimental group and a contrast group. Each group has 8 people whose ages are more than 40. The experimental group did a training for left-hand back swing for 8 weeks. The contrast group did training as they usually did. We could see some difference of the flying distance and accuracy of the experimental group or the contrast group by a counterpart specimen t-verification. 1. There is some difference in the result of the flying distance and accuracy after the training for left-hand back swing of the experiment group. 2. There is little difference in the result of the flying distance and accuracy after the training as they usually did. We can see that the training for left-hand back swing has an effect on the flying distance and the accuracy. According to these results, People(not only middle-aged women but old people lacking of physical strength who do exercise in wrong way) would have a good result at a match. If we add the training for the left lower part of the body(Follow Through to Finish) to a next research, it will be a deeper research. It will be also a more reliable research on condition that we experiment with more specimens.

알콜에 의한 면역반응 변조

박영민,오양호 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.3

Ethanol(EtOH) has an immunomodulatory, largely suppressive, influence upon the immune system. The present study was undertaken to investigate the effects of EtOH feeding on immune response potential by analyzing various parameters of immunocompetency in mice. Experimental groups of mice were fed ad libitum both pellet and 20% EtOH solution in their drinking water for 60 days. Control mice were fed a similar diet and water. Concanavalin A(Con A)-induced proliferation of splenocytes, and the expression of interleukin(IL) 2 receptor and changes of T cell subsets of thymocytes were analyzed by microculture technique and flow cytometry, respectively. Nitric oxide(NO) has been identified recently as a multifunctional mediator in biological response. NO has been known to be produced by most cells and influence on most cells of the body. The released NO could be toxic to immune and inflammatory cells as well as microorganisms and tumor cells. Thus, NO might be regarded as both immune effector and regulatory molecules. In this study, the authors intended to observe the effects of EtOH on the release of NO and the expression of inducible nitric oxide synthase(iNOS) mRNA of peritoneal macrophages. We have also assessed the ability of animals to respond to a sublethal dose of Cryptococcus neoformans to determine whether EtOH alters host defense mechanisms. It was found that mice fed with EtOH solution showed a significant suppression in Con A-activated proliferation of splenocytes and the number of the CD4+CD8- cell subsets. Interestingly, EtOH feeding did not induce the changes of IL 2 receptor expression in mice. The feeding of EtOH before C. neoformans infection enhanced significantly the recovery of C. neoformans from brain and spleen of the infected mice as compared to that of control mice. NO production and iNOS mRNA expression were decreased in EtOH-fed mice. In summary, our study findings show that EtOH ingestion in experimental animals results in demonstrable changes in T cell function and NO production as measured by in vivo and in vitro assays of immunocompetence. These changes obviously may increase the susceptibility of mice to fungal infection. It is still unclear how EtOH affects host defense mechanisms but this model will provide a useful system to define these mechanisms.

In this article, I look at the natural language processing(NLP) methods that Korean language teachers can perform in the context of writing education, and show the significance of text visualization methods based on the results of NLP. I saw it divided into two. I discussed the evaluation characteristics of Korean language teachers of students who can know. For this reason, NLP was divided into text collection, text preprocessing, and text analysis, and the activities that Korean language teachers should perform at each stage were discussed. NLP performed in the context of composition education has the same aspects as general text analysis and processes, but there are additional special items that come from the situation of composition education. In the chapter that follows this, the significance of the text visualization method is divided into a writing instruction phase and a writing evaluation phase, and there are methods for selecting and presenting words taught by Korean language teachers, and text visualization methods. There are advantages to be discussed, such as points to note when applying this method. 이 글에서는 작문 교육의 국면에서 국어교사가 수행할 수 있는 자연 언어 처리 방법을 살펴보고, 자연 언어 처리 결과를 기반으로 한 텍스트 시각화 방법의 의의를 작문 지도의 국면과 작문 평가의 국면으로 구분하여 살펴보았다. 이를 통해서 알 수 있는 학생 텍스트에 대한 국어교사의 평가 특성에 대해서 논의하였다. 이를 위해 자연 언어 처리 과정을 ⑴ 텍스트 수집 단계, ⑵ 텍스트 전처리 단계, ⑶ 텍스트 분석 단계로 구분하고, 각 단계마다 국어교사가 수행해야 할 활동을 논의하였다. 작문 교육 국면에서 이루어지는 자연 언어 처리 과정은 일반적인 텍스트 분석과 과정과 동일함 면이 있지만 작문 교육의 상황에서 오는 특별한 사항이 추가적으로 존재한다. 이를 토대로 이어지는 장에서는 텍스트 시각화 방법이 주는 의의를 작문 지도 국면과 작문 평가 국면으로 구분하여, 국어교사가 지도할 단어의 선정과 제시의 방법, 텍스트 시각화 방법이 가지고 있는 장점, 이 방법을 적용할 때의 유의점 등에 대해서 논의하였다. 이후로도 이와 관련한 논의가 지속적으로 이루어져 작문 교육이 더욱 더 체계적으로 발전할 수 있기를 기대한다.

The purpose of this study was to investigate that the effect of sugar alcohol such as sorbitol and xylitol on the growth of oral microorganism. The Gram positive facultative cocci and cariogenic bacteria, Streptococcus mutans KCTC 3065, and candidiasis (bleeding gum, dry mouth and tongue, thrush) inducing yeast, Candida albicans KCTC 7122, were used in this study. The results were as follows: 1) Practically xylitol is not fermented by Streptococcus mutans KCTC 3065 at all. 2) Enrichment of each xylitol or sorbitol did not any drop of pH of culture broth. 3) Thus xylitol may be contain bacteriostatic effect of cariogenic bacteria(S. mutans KCTC 3065). 4) However, the sugar alcohol has little effect on the growth of Candida albicans KCTC 7122 than that of S. mutans KCTC 3065. In conclusion, this may explain that xylitol is more useful non-cariogenetic sugar than that of sorbitol.

골프의 한국 도입과 발전과정

박영민 한국체육사학회 2002 체육사학회지 Vol.10 No.-

Golf had been recognized as a 'conspicuous consumptional sport' by a minority of privileged classes only ten years ago. However, after 1990's, golf has become more accessible to the general public as a national income and leisure time air increasing and the interest in leisure sports is growing in the wake of economic development. The purpose of this research paper is to view how golf has changed and settled in the public, and how it has been established as one of national favorite sports in a chronological order. Additionally, this paper categorizes the introduction of golf and the process of development into separate stages: introductory, receptive, settling, and developmental period, viewing golf from a social, political, and environmental point of vlew. The introductory period was from the flowering time to the restoration of independence. During the flowering time, mostly foreigners enjoyed golf and after 1920, an increasing number of Koreans played golf in new golf curses. Some of them produced remarkable results in Korea and Japan as well. Like other sports, the victory in golf made a significant contribution to elevating a national spirit and improving people's morale. The second period of golf was from independence of Korea in 1945 to the Third republic time. At the time golf was considered something inaccessible among people as a luxurious sport, and golf craze surged among the rich as a result of the remarkable economic development. Therefore, golf in this Period was generally accepted as a conspicuous consumptional sport which was limited to some privileged classes. The third period was the fifth and sixth republic time when golf in Korea settled with economic development reaching a certain standard. New rich classes who had accumulated a higher income turned to golf, accompanying the prosperity of golf industry to satisfy the demand. The fourth period was when golf in Korea bloomed, reached a fuming point and achieved its popularization despite several times of ups and downs. The national desire for leisure activities and impressive athletic achievements of several Korean golfers in international games greatly contributed to the popularization of golf in Korea after golf had been introduced to our country 100 years before.
