손원호,현승권 한국학교체육학회 2004 한국학교 체육학회지 Vol.14 No.1

본 연구는 최근 유아교육에서 중요한 교육영역으로 자리잡아가고 있는 유아체육 활동의 지도를 담당하고 있는 지도자들의 사기저하 요인을 살피보고 이를 근거로 하여 유아교육기관에서 활동하고 있는 유아체육 지도자들의 사기저하 개선방안을 규명하는 것이 목적이다. 이와 같은 목적을 달성하기 위하여 2003년 12월 현재 서울, 대전, 대구, 부산, 광주의 유아교육기관을 전집으로 하여 407명을 표집하여 유아체육지도자들의 사기저하요인을 분석하였으며, 그에 따른 개선방안을 제시하였다. 분석한 결과 다음과 같은 결론을 얻을 수 있었다. 첫째, 지역에 따른 유아체육지도자들의 사기저하 요인을 살펴보면, 정서적 탈진의 경우 부산지역이 사기저하가 크게나타났으며, 대구가 가장 낮게 나타났다. 비 인격화는 대전이 가장 높고 대구가 가장 낮게 나타났으며, 개인적인 성취감은 부산지역이 사기저하가 가장높교 광주가 가장 낮게 나타났으며, 성별에 따른 사기저하요인은 정서적 탈진의 경우 여자가 남 자보다 사기저하가 높게 나타났으며, 비인격화는 여자가 남자보다 높게,개인적인 성취감은 별차이가 나타나지 않았다. 둘째, 연령에 따른 사기저하요인은 36세 이상이 사기저하가 가장 높고 23세이하가 가장 낮게 나타났으며, 비인격화는 31세-35세가 사기저하가 가장높게 나타났으며, 23세 이하가 가장 낮게 나타났다. 셋째, 학력에 따른 사기저하요인을 살펴보면,정서적 탈진은 비체육계대학(원)졸이 사기저하가 가장 높고 기타가 가장 낮게 나타났으며 1%이내에서 통계적인 유의차가 나타났다. 비인격화는 체육계대학졸이 사기저하가 가장 높게 나타났으며 기타가 가장 낮게 나타났으나 유의한 차이는 나타나지 않았다. 개인적 성취감은 비체육계대학졸이 사기저하가 가장 높게 기타가 가장 낮게 나타났으나 통계적인 유의차는 나타나지 않았다. 넷째, 직위에 따른 사기저하 요인을 살펴보면, 기타가 가장 높고, 아르바이트가 가장 낮게 나타났고, 비 인격화는 경영 및 전임지도자가 사기저하가 가장 높게 나타났으며, 아르바이트가 가장 낮게 나타났다. 결론적으로 유아체육 지도자들은 사회적으로 대우를 받아야 함에도 불구하고 유아교육기관에 체육교사라는 직위가 인정 되지 않아 정기적인 승진(교사호봉), 직장의료보험, 연금등에서 제외됨과 동시에 유아교육기관에 종사하는 젊은 남자가 없어 수업외 여러 잔무에 시달리고 있는 실정이다. 따라서 이제는 유아교육기관에서는 기존의 유아체육 지도자들의 직위를 인정해 주어야 하며, 정기적인 승진, 호봉인상 등에서 제외 되는 일이 없어야 할 것이다. 아울러 전문적이고, 체계적인 대학(2년제 대학포함)에서 유아체육 교사를 양성 배출해야 할 것이다. 또한 개인의 발전을 위하여 상급 학교에 진학하여 꾸준히 노력하는 것이 중요하다고 하겠다. The purpose of this essay is to explore the factors of demoralization of the educators taking charge of the instruction of child physical activity taking its foothold as an important area in child education, and closely examine into the reform plan of demoralization of child physical educators acting at child educational institutions based on it. To achieve this goal, 407 subjects were sampled from the child educational institutions in Seoul, Daejeon, Daegu, Busan, and Gwangjoo as of 2003, and the factors of demoralization of child physical educators were analyzed, and its reform plan was presented. As a result of analysis, following conclusion was obtained. First, the factors of demoralization of child physical educators by region, in case of emotional exhaustion, demoralization was the highest in Busan area, and the lowest in Daegu. in case of inhumanity, it was the highest in Daejeon, and the lowest in Daegu, and personal achievement, it was the highest in Busan and the lowest in Gwangjoo. Second, the factors of demoralization by gender, in case of emotional exhaustion, demoralization was higher in women than men, in case of inhumanity, it was higher in women than men, and in case of personal achievement, there was little difference, which means that women feel more burdensome in classes than men. Third, the factors of demoralization by age, in case of emotional exhaustion, it was the highest at those of 36 or higher, and the lowest at those of 23 or lower, in case of inhumanity, it was the highest at those between 31 and 35, and the lowest at those of 23 or lower. Fourth, the factors of demoralization by career, in case of emotional exhaustion, it was the highest at those with 5 year or more career, and the lowest at those of 1 year or less career, in case of inhumanity, it was the highest at those of 5 year or more career, and the lowest at those of 5 year or less career, and in case of personal achievement, it was the highest at those of 5 year or more career, and the lowest at those of 3 year or less career.. Fifth, the factors of demoralization by marriage, demoralization was higher in the married than the unmarried, which means that many careered subjects are concerned with the status upwardness. Sixth, the factors of demoralization by school background, in case of emotional exhaustion, it was the highest at those of non-physical education graduates, and the lowest at the others, which showed statistically significant difference within 1%, in case of inhumanity, it was the highest at those of physical education graduates, and the lowest at the others, which did not show significant difference. And in case of personal achievement, it was the highest at those of non-physical education graduates, and the lowest at the others, which did not show statistically significant difference. Seventh, the factors of demoralization by monthly income, in case of emotional exhaustion, it was the highest at 1.80-2.50 million won, and the lowest at the others, which did not show statistically significant difference, in case of inhumanity, it was the highest at 1.80-2.50 million won and the lowest at the others, which showed significant difference within 0.1%. And in case of personal achievement, it was the highest at 0.8 million won, and the lowest at the others, which did not show statistically significant difference. Eighth, the factors of demoralization by position, it was the highest at the others and lowest at part time job, in case of inhumanity, it was the highest at manager and full time educators, and the lowest at part time job. In conclusion, as it may be the case, child physical educators should be socially treated, but they have not had physical teachers' position recognized, so they are excluded from regular promotion (teachers' salary step), vocational medical insurance, and pension, and troubled with many miscellaneous works as there are no young male workers engaged in child educational institutions. Accordingly, child educational institutions should recognize child physical educators' position, and not exclude them from regular promotion, rise of salary step. In addition, specialized and systematic colleges (including 2 year system colleges) should cultivate and produce child physical educators.

본 연구에서는 임목수확작업에 사용되는 집재기계의 작업효율성을 분석하여 경사가 급한(20° 이상) 작업조건에 적합한 가선계 집재기계를 선정하는데 기초 정보를 제공하고자, 타워야더(RME-300T), 트랙터부착형 집재기(일명: 춘천집재기), 트랙터윈치(FARMI) 등에 의한 집재작업에서의 작업생산성 및 비용을 비교 분석하였다. 평균 흉고직경이 20 cm, 집재거리 60 m, 가로집재거리 10 m, 그리고 기계이용률이 70%인 동일한 작업 조건에서 작업이 이루어질 경우, 타워야더의 1일 집재작업 생산성은 33.04 m3/일, 트랙터부착형 집재기는 38.47 m3/일, 그리고 트랙터윈치는 14.17 m3/일으로 분석되었으며, 이에 따른 집재작업비용은 각각 25,105원/m3, 20,520원/m3, 37,835원/m3으로 나타났다. 동일한 작업조건에서 집재거리에 따른 각 집재기계별 작업효율성을 비교하였을 경우, 집재거리가 40 m 이내로 짧을 경우에는 트랙터윈치에 의한 집재작업이 효율적이며, 40~140 m의 집재거리에서는 춘천집재기가, 140 m 이상의 장거리 집재작업에서는 타워야더가 가장 효율적인 것으로 나타났다. This study was conducted to provide field-based harvesting study information which can be used to select an optimal cable system for certain work conditions on steep grounds (>20° ground slope) in Korea. Toaccomplish this study objectives, we evaluated three cable yarding systems (RME-300T tower-yarder, Chuncheontower-yarder, FARMI tractor winch) working in typical work conditions for their yarding productivity and operational efficiency. Those yarders are commonly used for removing logs or trees on steep grounds in Korea. Under the same work conditions (average DBH of tree to be cut, 20 cm; yarding distance, 60 m; lateral yardingdistance, 10 m; and machine utilization rate, 70%), the average productivities were 33.04 m3/day, 38.47 m3/day, and 14.17 m3/day for RME-300T, Chuncheon tower-yarder, and FARMI, respectively. Our standardized cost comparison study also showed that the yarding cost was highest at 37,835 won/m3 with FARMI, followed byRME-300T at 25,105 won/m3 for the same work conditions. We found the lowest yarding cost with the Chuncheon tower-yarder at 20,520 won/m3 which was resulted primarily from high yarding productivity at theyarding distance (60 m). Our analysis suggested that a small machine such as FARMI could be a low-costyarding machine option for a cable yarding job with a short yarding distance (40 m or less). The Chuncheontower-yarder is well suited for a mid-range yarding distance job in Korea, ranged between 40 to 140 m. Ifyarding distance were longer than 140 m, the RME-300T tower yarder appears to be most cost-effective.

김지원,박상현,주성희,김용권,안덕현,Kim, JI-Won,Park, Sang-Hyeon,Joo, Sung-Hui,Kim, Yong-Kwon,Ahn, Duck-Hyun 대한물리치료과학회 2003 대한물리치료과학회지 Vol.10 No.2

This study randomly chose 10 humanity high schools, which are located in Busan and KyoungNam province. We then examined the recognition rate of physical therapy among 378 teachers who were and still are working in the schools. 1. The recognition grade of physical therapeutics between men and women was significantly different with results of 80.7% of men and 69.7% of women(p<0.05). In the case of experiencing physical therapy, 83.6% of people said they knew the physical therapeutics and in the case of the opposite side, the result was also significantly different with a result of 67.8%(p<0.05). 2. We ranked the people on how much they knew about the physical therapeutics among men and women. With men, the actual experience of physical therapeutic came before what they heard from other people. In the case of women, what they heard from other people came first and the actual experience of physical therapeutic came after. According to the public information from Inje University, the recognition grade is recorded in the 3rd grade department as 21.5% while in the case of experiencing treatment from a physical therapist, the result was 39.1%. In the other department (the 1st grade department), what men and women heard from mass media was recorded at 17.5% and what they heard from other people, it was recorded at 33.8%(p<0.05). 3. The research about the recognition of academic ability of being a physical therapist was that 55.6% of teachers thought that 3-year-college was the best, which made the results different from the recognition grade of the experience of education(p<0.05). 4. In the recognition grade of physical therapeutics, there were significantly differences from 50.2% of men and 45.2% of women were expecting about 1mil ion won to 1.99million won. In case of 25.2% of people who have experience less than 15years at work, they expected about 2million to 2.99million won. The figures were higher than 10.1% of people who have experiences over 15years. About the recognition grade of physical therapists social level in the future is 48.8% of people who had experienced of physical therapy and 63.8% of people who never had experienced of it said it would be better in the future. From these results, the recognition about physical therapeutics and the view of its social status are optimistic and they know well about the level of academic ability of physical therapists. On the other hand, most teachers don't know exactly about physical therapists work. So we have to inform them aggressively for enhancing the recognition of physical therapy because high school students are well affected by their teachers when they face their future or major in university.

권성준,최갑림,임성훈,김광원 대한치과교정학회 2004 대한치과교정학회지 Vol.34 No.5

일반인들이 선호하는 상순과 턱의 수직 비율(Sn-Stm/Stm-Me')을 알아보기 위해 남녀 각 2명의 연조직 측모(profile)를 상순과 턱의 수직비율에 따라 상악의 변화없이 하악만을 변화시켜 1/1.8, 1/1.9, 1/2.0, 1/2.1, 1/2.2 비율의 5개의 측모 사진을 만들어 치과의사 44명(남자 22명. 여자 22명)과 일반인 430명(남자 303명, 여자 127명)을 대상으로 하여 설문조사를 통하여 선호도를 조사하여 다음과 같은 결과를 얻었다. 대상의 가장 선호하는 안모에 대한 성별간의 선호도 차이는 통계적으로 유의하지 않았다. 대상의 가장 선호하는 안모에 대한 치과의사와 일반인 집단간의 선호도 차이는 통계적으로 유의하지 않았다. 남녀 측모 모두에서 가장 선호하는 측모의 상순과 턱의 비율은 1/1.9이었으며 가장 선호하지 않는 비율은 1/2.2 로 나타났다. 이상의 결과를 종합하여 볼 때, 이전의 연구 비해 상순과 턱의 수직비율에서 턱의 비율이 다소 작은 측모, 즉 상순과 턱의 수직 비율이 1/1.9인 안모를 가장 선호하는 것으로 나타났다. The purpose of this study was to investigate the preference of Vertical Lip-Chin Ratio (= Sn-Stm /Stm-Me' hereafter VLCR) in Koreans. The assessors consisted of 44 dentists (male 22, female 22) and 430 lay persons (male 303, female 127). The survey was performed using a questionnaire asking the order of preference. The profiles presented in the questionnaire were based on the profiles of two males and two females, each morphed according to the VLCRs of 1/1.8, 1/1.9, 1/2.0, 1/2.1, 1/2.2. The results were as follows: The difference between males and females, and the difference between dentists and lay persons in the preference of VLCR were not statistically apparent. The most preferred VLCR was 1/1.9, and the least preferred VLCR was 1/2.2. These results indicate that the preferred VLCR is smaller than the previously reported VLCR ratios based, on the cephalometric evaluation of samples with favorable facial esthetics.

Hybrid Glass Ionomer cement의 비커스경도와 간접인장강도에 관한 연구

권균원,박상진 大韓齒科保存學會 1997 Restorative Dentistry & Endodontics Vol.22 No.2

The objective of this investigation was to compare the effects of water storage on the aspect of hardness and diametral tensile strengths of four hybrid glass ionomer cements(two compomers and two resin-reinforced glass ionomers) with a resin composite material. One composite resin(Degufill Ultra), two compomers(Dyract, Compoglass Cavifil), and two resin-reinforced glass ionomers(Fuji Duet, Vitremer) were used in this study. Cylindrical specimens were prepared and stored at 36±1℃ in distilled water for 10 minutes after set, and then tested on an Instron testing machine(No.4467) at 1.0mm/min displacement rate. Vicker's hardness and diametral tensile strengths as time elapsed were measured after aging in water for 10 minutes, 1 hour, 3 hours, 1 day, 3 days, 5 days and 7 days at 36±1℃. During the test of diametral tensile strength, stress-strain curves were obtained, from which the compressive modulus were calculated and compared. The structure of four set glass ionomer cement mass was observed on SEM(Hitachi, S-2300) after being etched with 9.6% hydrofluoric acid for 1 minute. The results were as follows; 1. The hardness of the experimental group(compomer and the resin reinforced glass ionomer cement) did not exceed the value of control gorup(Degufill Ultra). 2. Vicker's hardness of the Fuji Duet tended to increase succeedingly, Dyract was decreased after 3 hours in water, and Vitremer was the lowest. 3. The control group(Degufill Ultra) presented progressively on increased diametral tensile strength with time, Fuji Duet were decreased after 3 days, Compoglass Cavifil and Vitremer were decreased after 5 days in water storage. 4. Compressive modulus of the control group(Degufill Ultra) and Dyract were increased sharply timely, Fuji Duet and Vitremer were increased smoothly by lapse of time in water. Fuji Duet were stronger than Vitremer. On the other hand, Vitremer exhibited the lowest toughness. 5. The microstructure of compomer was similar with that of the composite resin(Degufill Ultra), and the fillers in resin-reinforced glass ionomer cements were noticed. It can be concluded that mechanical properties of hybrid glass inomer cements is weaker than composite resin, and that the compomers or the resin-reinforced glass inomers can not substitute the composite resins. A plenty of considerations should be done on the application of them to the area under the loading and high wear has a little adverse effect on the mechanical properties on the water storage for 7 days. The further research should be needed to confirm the advantage of the compomer.
