The purpose of this study was to identify the effect of shout-term oral creatine administration of maximum strength and body composition. For this purpose, specialists in yudo and undergraduates in 'Y' University were selected as the subjects of this study and 5 persons were each randomly assigned to the group of training plus creatine, to the group of only training and to the group of only creatine administration. They were asked to ingest 20g of creatine with ionized beverage and water after breakfast, lunch and supper and before bedtime(5g x 4 times) everyday for 6 days. They was asked to conduct weight training three time a week, and sports events included bench press, leg extension, leg curl, arm curl, shoulder press and the like. The repeated them at the workload of 70∼80% of I-RM and conducted each motion in three sets. To measure muscular strength as the variable to be tested, an attempt was made to measure bench press I-RM, leg extension I-RM, leg curl I-RM, arm cur I-RM, shoulder press I-RM before and after training. An attempt was made to determine such factors related to body compostion as weight, body fat amount and body fat ratio using the Inbody 3.0 Body Compostion Analyzer. Creatine analysis was conduct through creatine in urine by using the biochemical analyzer(Model-Ha TACHI 747/737, HITACHI CO. Japen). Repeated two-way ANOVA was used to analyze data. Hypotheses were tested at the significance level of d=.05. As a result, the following results were obtained: 1. It was found that both of the groups showed a significant defference in bench press, leg extension, leg curl, arm curl, shoulder press, incline bench press, should machine, sit-up I-RMs before and after participation in short-run weight training(p<.05). But there was no difference in them between groups. And it was found that there was no interaction before and after creatine administration and one-week weight training. (p>.05). 2. It was found that there was no signigicant variation in body composition(body fat amount changes and body fat ratio changes) before and after shout-run weight training(p>.05). And it was found that there was no interaction before and after creatine administration and one-week weight training(p>.05). 3. It was found that there was no significant variation in the urinalysis before and after short-run weight training(p<.05). And it was found that there was no interaction before and after creative administration and one-week weight training (p>.05).

Objectives This study was conducted to investigate the demographic characteristics, periodontal disease, anxiety, and depression of adult women who are highly sensitive to psychological factors to find out the relationship between anxiety and depression and periodontal disease according to demographic characteristics. Methods The original data of the 8th 2nd year (2020) of the National Health and Nutrition Survey organized by the Korea Centers for Disease Control and Prevention were used, and 2,368 copies were finally analyzed after receiving approval for the use of the data after submitting documents such as the original data, user security pledge, etc. on the website (https://knhanes.kdca.go.kr ). For data analysis, a chi-square test was conducted using SPSS/Win 20.0 to find out the difference in demographic and oral health-related characteristics and periodontal diseases, and univariate regression analysis was conducted to find out the number of toothbrushes and periodontal diseases caused by the use of dental floss and interdental toothbrushes. Multiple logistic regression analysis was conducted to find out the effect of periodontal diseases on anxiety and depression, and multivariable logistic regression was conducted to find out the relationship between demographic characteristics and anxiety and depression experiences. Results The older the age, the higher the periodontal disease, and the higher the income and education level in the case of no experience of periodontal disease for the last one year. It was found that the number of times of brushing more than three times a day and the use of dental floss/interdental toothbrushes significantly increased the risk of periodontal disease, and periodontal disease significantly increased anxiety and depression. The experience of anxiety and depression was high in separation/divorce/divorce. The factor related to the experience of anxiety and depression was found to be marital status. Conclusions It will be necessary to improve professional accessibility such as counseling by developing and providing regular and continuous depression management and prevention programs that can be easily accessed by anyone and the need for regular periodontal management and effective oral health management education to efficiently manage periodontal diseases.

Due to the growth of the drone industry, side effects have also begun to increase. Unthinkable damages such as invasion of privacy through cameras, illegal trespassing of private land, and damage caused by the drone crash began to occur. The most serious problem is the combination of illegal drones and terrorism. Terrorism behavior of illegal drones should be different from the existing defense system against terrorism. A defense system of concentric structure consisting of prevention-deterrence-denial-detection-destruction should defend the offensive behavior of illegal drones. Only when an overlapping defense system is established can we effectively defend the offensive behavior of illegal drones. However, it is believed that such discussions have not yet been active in Korea, and defense systems should be in place to suit the characteristics of each facility, including national important facilities, Cheong Wa Dae and the airport. In particular, the focus was on the incapacitation measures considered to be the most important part of the defense system. Destruction measures are divided into electronic and physical responses. Electronic responses have been legalized through the revised Radio Waves Act, and there is virtually no basis for physical responses. The general provision that a special security guard in charge of the security of each facility may use weapons alone cannot defend against illegal drone attacks. Of course, the basis for the current electronic response is simply a regulation that allows the use of jammer. The purpose of this paper is to prescribe clear and specific procedures for destruction measures so that they can be applied directly to the airport.

This study was conducted to analyze the survey on clinical practice for university students enrolled in the health department of some rural universities to provide basic data to help change the perception of clinical practice education, lay the foundation for efficient operation and systematic education, and to develop clinical practice programs. During the study period from March to June 2024, a self-written questionnaire was conducted, and the survey method was distributed and collected using collection, distribution survey, and mail delivery, and 1,392 copies were used for the final analysis. For data analysis, a frequency analysis was conducted for general characteristics using SPSS/Win 25.0 and the difference in clinical practice experience according to general characteristics, in-school clinical practice anxiety resolution, in-school clinical practice institutions, in-school clinical practice period, in-school clinical practice, in-school atmosphere, and in-school pride and achievement in occupation were x²-tested. The interdisciplinary system was somewhat more than three-year, the third grade was more, and the clinical experience was more on-campus+out-of-school. In terms of the difference in clinical practice experience according to general characteristics, in the case of the interdisciplinary system, the on-campus system was high, the four-year system was high on-campus, the first grade was high, the second grade was high on-campus, and the third and fourth grades were high on-campus+out-of-school. In terms of the difference in resolving anxiety in clinical practice on campus, both the three-year and four-year systems were usually high in the case of the school year, the first, second, and third grades were generally high, and the fourth grade was usually resolved. In the case of the interdisciplinary system, in the case of differences in suburban clinical practice institutions, university hospitals were high in both the three-year and four-year systems, individual clinics were high in the first grade, and university hospitals were high in the second, third, and fourth grades. In the case of the interdisciplinary system in the difference in the period of suburban clinical practice, 8-12 weeks were high in both the three-year and four-year systems, and 8-12 weeks were high in the case of the first grade, and 8-12 weeks were high in the second, third, and fourth grades. In terms of the difference in job pride and achievement, in the case of the interdisciplinary system, the three-year system was usually high, the first grade was more likely to have a four-year system, the second and third grades were usually high, and the fourth grade was more likely to have. As a result of the above, it will be necessary to develop a comprehensive and objective clinical practice education program that can supplement the essential contents to be practiced in the clinical field, and to provide continuous practice guidance and effective evaluation after clinical practice through linkage between the school and the clinical field. In the future, research related to this should be conducted more actively, and it is considered that various studies on the clinical practice environment and practice evaluation methods should be conducted.

문선정,가경환,김은희 한국도서(섬)학회 2018 한국도서연구 Vol.30 No.4

The purpose of this study was to develop an oral health program for workers with special occupations, such as police officers, and present the basic data necessary to implement oral health projects. For this purpose, a self-administered survey was conducted on police officers at police stations, in police patrol units, and at police boxes in rural areas for a week in, July 2017; a total of 559 questionnaires were returned and analyzed; incomplete copies and those completed insincerely were excluded. Dental caries differed significantly by age group: the respondents in their fifties or older were more likely to have it than those in their thirties or forties. The high school graduates or those at lower education levels were more likely to be affected by foods and bacteria than the college graduates or those at higher education levels. The respondents earning 3.1-4 million won were more likely to be affected genetically than those earning 4.1 million or <2.5 million won; the respondents earning 2.6-3 million won were more likely to be affected by bacteria than those earning ≥4.1 million won; and the respondents earning 2.6-3 million or 3.1-4 million won were more likely to have it in general than those earning ≥4.1 million won. The respondents in their thirties and forties had better periodontal health in terms of oral causes and treatment than those in their fifties or older; the respondents in their twenties and thirties also had better periodontal health in general than those in their fifties or older. The unmarried had better periodontal health both in terms of oral changes and general care than the married; the college graduates had better periodontal health in terms of oral changes and causes and treatment than the university graduates or those at higher education levels or the high school graduates or those at lower education levels. The respondents earning <2.5 million won had better periodontal health in terms of oral changes than those earning ≥4.1 million or 2.6-3 million won; the respondents earning <2.5 million or 2.6-3 million won had better periodontal health in terms of oral causes and treatment than those earning ≥4.1 million won. The respondents in their thirties and forties were more likely to be affected by fluorine in preventive treatment than those in their fifties or older; the respondents in their thirties had better preventive treatment than those in their fifties or older. The high school graduates or those at lower education levels were more likely to be affected by fluorine than the college graduates or those at higher education levels; the high school graduates or those at lower education levels were more likely to be affected by fluorine types and sealants than the college graduates or those at higher education levels; the former group had better preventive treatment in general than the latter group. The respondents earning <2.5 million won were more likely to be affected by fluorine than those earning ≥4.1 million, and the respondents earning 2.6-3 million won were more likely to be affected by fluorine than those earning ≥4.1 million, 3.1-4 million, or <2.5 million won; in addition religion made significant differences in fluoric effects, fluorine type, the effects of sealant, and general treatment. On the basis of these results, if police officers are given highly preferred oral health education and supportive environments appropriate for them to prevent dental caries and periodontal diseases, which are representative adult oral diseases among them, it is expected that oral health may be successfully promoted and consequently their work is made more efficient. 본 연구는 경찰공무원과 같은 특수직종에 종사하는 근로자를 대상으로 구강보건프로그램 개발과 향후 구강보건사업에 필요한 기초자료를 제시하고자 일부 농어촌 지역 경찰서·지구대·파출소에 근무하는 경찰공무원을 대상으로 2017년 7월부터 일주일간 자기기입식 설문조사를 실시하였고, 설문작성이 미완성되거나 응답이 불분명한 자료를 제외한 총 559부의 설문지를 회수, 분석하였다. 치아우식증은 연령요인에서 유의한 차이가 나타났고, 50대 이상이 30대, 40대 보다 높았다. 학력에서는 음식요인과 세균요인에서 고졸 이하가 대졸 이상, 전문대졸보다 높았다. 소득에서는 유전요인에서 310-400만원이 410만원, 250만원 미만보다 높았고, 세균요인에서 260-300만원이 410만원 이상 보다 높았으며, 전체에서는 260-300만원, 310-400만원이 410만원 이상 보다 높았다. 치주건강은 연령의 경우 구강원인과 치료에서 30대, 40대가 50대 이상보다 높았고, 전체는 20대, 30대가 50대 이상보다 높았다. 결혼여부는 구강변화, 전체에서 미혼이 기혼보다 높았고, 학력은 구강변화 및 구강원인과 치료에서 전문대졸이 대졸 이상, 고졸 이하보다 높았다. 소득에서는 구강변화에서 250만원 미만이 410만원 이상, 260-300만원 보다 높았고, 구강원인과 치료에서는 250만원 미만, 260-300만원이 410만원 이상 보다 높았다. 예방진료에서 연령은 불소영향에서 30대, 40대가 50대 이상보다 높았고, 전체는 30대가 50대 이상보다 높았다. 학력은 불소영향에서 고졸 이하가 대졸 이상, 전문대졸보다 높았고, 불소종류와 실란트 영향은 고졸 이하가 대졸 이상, 전문대졸보다 높았으며, 전체는 고졸 이하가 대졸 이상, 전문대졸보다 높았다. 소득은 불소영향에서 250만원 미만이 410만원 이상 보다 높았고, 260-300만원이 410만원 이상, 310-400만원, 250만원 미만 보다 높았으며, 종교는 불소영향, 불소종류와 실란트 영향, 전체에서 유의한 차이가 나타났다. 이상의 결과 경찰공무원의 대표적인 구강질환인 치아우식증과 치주질환을 예방하기 위해 집단의 특성에 맞는 선호도가 높은 구강보건교육 및 지원환경을 구축하여 구강질환을 예방한다면, 구강건강을 증진시켜 업무의 효율성도 더불어 기대할 수 있을 것으로 사료된다.
