This paper was to investigate the effect of mixing time on the rejection of magnesium in polyelectrolyte enhanced ultrafiltration with PSS[poly(sodium-4-styrenesulfonate)] and PDDA[poly(diallyldimethylammonium chloride)]. The removal ratio of magnesium, the rejection ratio of polyelectrolyte, and the Permeate flux were stable within 10 min of mixing. PSS is more effective than PDDA in the removal of magnesium. When PSS of 2.000 ㎎/L was used. the removal ratio of magnesium was 78%. The rejection ratios of PSS and PDDA in Mg solution were up to 95.9% and 95.7%. respectively.

The purpose of this study is to secure the stability of the Korea hand function work sample test by conducting verification of reliability & validity. In order to verify reliability⋅validity of developed Korea hand function work sample test, the test based on 206 people with disabilities was conducted. The each existing Purdue Pegboard and developed Korea hand function work sample test were conducted randomly, and the test-retest method was conducted by same examiner repeatedly in order to measure reliability of Korea hand function work sample test. The criterion validity were verified, and sensitivity․specificity were shown by written ROC curves. The criterion validity was verified by comparison with Purdue Pegboard which is used as existing useful tool. First, all correlations of Korea hand function work sample test in the test-retest reliability are significant from 0.01 level and it shows very high correlations of more than 0.95 between the tests. Second, the Korea hand function work sample test shows high correlation between the existing Purdue Pegboard and test. Third, the predictive power of the AUC value was appeared high with 0.886, 0.868 in the results of the Korea hand function work sample test by using ROC curves. Fourth, Korea hand function work sample test was developed as useful tools with high convenience degree & failure prediction comparing to Purdue Pegboard. The Korea hand function work sample test is significant for the first developed work sample test tool in Korea which secured reliability and validity and it is expected to help for practical service provision of vocational evaluator for the disabled. 본 연구의 목적은 국내에서 개발된 한국형 손기능 작업표본검사의 신뢰도 및 타당도 검증을 실시하여 장애인의 손기능을 평가하고, 직업능력을 예측하는데 활용할 수 있도록 검사의 안정성을 확보하는 것이다. 한국형 손기능 작업표본검사의 신뢰도⋅타당도 검증을 위해 15세-55세의 비장애인 56명, 장애인 206명(지체장애인, 지적장애인, 정신장애인, 뇌병변장애인)을 대상으로 하였다. 본 연구에서 수집된 자료는 SPSS WINDOW 13.0을 사용하여 통계처리 하였다. 검사-재검사 신뢰도를 위해서 반복측정 상관분석을 하였고, 민감도․특이도는 medcalc 프로그램 version 11.4.1을 사용하였고 ROC curves를 작성하여 한국형 손기능 작업표본검사와 퍼듀펙보드의 장애 예측 정도를 나타내었다. 준거 타당도 검증을 위해 기존의 도구와 paird t-test 및 카이제곱(chi-square) 검정을 실시하여 분석하였다. 분석결과 첫째, 한국형 손기능 작업표본검사는 검사-재검사 신뢰도에서 모든 상관이 0.01 수준에서 유의미하고 검사 간 상관이 0.95이상의 매우 높은 상관을 보이는 것으로 나타났다. 둘째, 한국형 손기능 작업표본검사가 기존의 퍼듀펙보드와 검사 간 상관이 높은 것으로 나타났다. 셋째, 한국형 손기능 작업표본검사는 장애 예측 민감도와 특이도를 ROC curves를 사용해서 나타낸 결과 AUC 값이 0.886, 0.868로 예측력이 높은 것으로 나타났다. 본 연구를 통해 국내에서 개발된 한국형 손기능 작업표본검사는 신뢰도와 타당도가 확보된 작업표본검사 도구라는 점에서 의미가 있고 장애인 직업능력평가의 실질적인 서비스 제공에 도움이 될 것으로 기대된다.

The experimental study on photocatalytic phenol removal was conducted by using TiO_(2) as a photocatalyst and ultraviolet(UV) ray as a light source. The effect of several variables such as the amount of photocatalyst, the wavelength of UV ray and the operation temperature and pH of reaction system on the removal efficiency of phenol was experimentally examined. Up to the concentration of photocatalyst 0.025g/L, the removal efficiency of phenol increased with the concentration of photocatalyst and beyond this concentration the reaction rate was independent of catalyst concentration. The removal of phenol was enhanced as the energy intensity was increased, that is the wavelength became shorter. It seemed that the photocatalytic decomposition of phenol prefers the basic condition and is insensitive to the operation temperature.

Objectives : Risperidone and olanzapine, which are atypical antipsychotics. are widely used in the treatment of schizophrenia as the 1st line drug, proving their effectiveness for both positive and negative symptoms. They also have many advantages even from the side effects. However, they show differences with the chemical structure and pharmacokinetics and they work differently to receptors. Researchers have studied the effect and side effect during the acute phase of schizophrenia as an open prospective study. Methods : Forty subjects with DSM-IV schizophrenia or schizoaffective patients including 1) 1st onset schizophrenia patient, 2) patient who has been treated by the prior antipsychotics and not improved or even worse to be admitted again, were assigned to receive risperidone or olanzapine for 6 weeks. Psychopathology, adverse effect. weight change, fasting serum glucose, and drug cost were compared within and across groups. Results : After 6 weeks later both treatment groups showed the significant decrease in PANSS positive, general psychopathology and total score while they did not show any significant difference between two groups. Risperidone group, however. showed the significant decrease in PANS negative score, which olanzapine group did not. In terms of adverse effect risperidone group showed more extrapyramidal symptom than olanzapine group. Body weight rised significantly after Gweeks, but no significant difference between two treatment groups. There were no significant indrease of fasting serum glucose level. Conclusions : Risperidone and olanzapine are effective drugs which can be used during the acute phase of schizophrenia. Risperidone is expected to shorten the admission day and remission of the symptom of acute phase, mile olarizapine is more advantage in a neurologic side effect than rispendone.

김성룡,손승건 群山大學校 1996 論文集 Vol.23 No.-
The average life-time in korea is becoming 80years old, and it is about 700,000 hours in the terms of life-time budget. Working hours of a year will be 2,000 hours in the near future. If a person works from 20 years old to 60 years old, working hours during 40 years will amount to 80,000 hours and this is about 10% of total life-time. On the other hand, free time will increase to 30% of total life-time. This structure of life-time budget causes the changes of people’s thoughts from that they live to work to that they work to live. According to the result of EPA research project, people who prefer the life pattern of ˝Child-Education-Work-Retire˝ will decease to 15%. On the other hand, people who prefer the life-pattern of ˝C→E→[W/Leisure/E]→E→L˝or ˝C→E→W→E/L→W→E/L˝will increase to 60%. Especially this patter is called recurrent life pattern. At current status, korea is behind in the area of reduction of work-time comparing with EC and U.S.A., bout we can survey carefully the states of theses advanced countries and analize their merit and demerit. Refering to the result, we should propose a method of allocation of life-time budget which is suitable to korea. Why carefully? Nowadays, in EC and U.S.A., the reduction of work-time is mainly for absorbing of unemployments and aiming at sharing work. But in case of korea, the quality of worker’s life should be investigated for the first time under a good economic environment. In those days of 50 years life-time, the National strategy was focused on the work-oriented industrial society, but in the era of 80 years life-time, the focus is moving toward how to be for good human’s life. Generally speaking, the moving from industrial society to post-industrial society has been argued by many sociologists. When this problem is reated with life-time budget, the change toward a learning society is becoming very important from the view points of social science, natural science and humanity. The autor’s scenario of method of allocation of life-time budget is based on the strategy change from a linear life pattern to recurrent life pattern.

There is a rising hobby in the COVID-19 pandemic era. At this point, camping accidents are also occurring a lot as more people are camping in cars and outdoors. Most of the casualties among them are carbon monoxide poisoning accidents. Therefore, to prevent carbon monoxide poisoning, we measured with an Arduino board using a "DHT22" sensor and an "MQ7" sensor to know temperature, humidity, and carbon monoxide levels, and then printed it out on LCD after storing it in Raspberry Pi database. Therefore, it is implemented through 3D printing on the appearance modeled directly to the actual user.

임광수,손승건 群山大學校 1995 論文集 Vol.22 No.-
The purpose of this article is aimed to construct a base of the theory on technique in sport from the consideration in a phenomenological-morphological aspect. The term "technique" is generally used in the field of sport practice and sport science. in fact, however. there is a crevice between practice and science. Scientist's greatest interest is mainly in the improvement of physical performance and psychological problems. And in sport science the study of technique is base on biomechanics, which hat its origins in physics, anatomy and physiology. However these studies have not dealt full with practical problem in sport. As MEINEL. K. pointed out, technique in sport is products of practical exerience, and people know also from their own experience this fact. Therefore, it is necessary to shift view point from the above scientific approach to the practical, namely, penomonological-morphological approach. This shift enables us to understand sport technique as an problem on the sport. Phenomenological-morphological approach presents some important considerations. on the basis of this understanding, problems of the technique in sport can be summarized as follows: movement form(Bewegungsgestalt) is dominated by a movement purpose: technique in sport is teleological problem: technique in sport has "noesis-noema" structure: technique in sport is "morphe" technique. In this way, the technique in sport is caused by subjective factor. This result is important to construct the "practical theory" on technique in sport.
