Every year, about 250,000 new recruits enter the military under the R.O.K military draft system. When the fresh soldier groups arrived at the Recruit Training Center, their supplies are distributed before they get basic military training. The supplies are divided by season, summer and winter. There are 14 class of summer items and 20 class of winter items, and the each class has about a few kinds of items. Totally, there are the hundreds kinds of supplies and the supplies distribution system is manually operated. However, in the current system, many problems such as spending a lot of time, manpower and high change rate due to the inaccurate distribution have been raised. This paper suggests the automated supplies distribution system to solve the above problems. We choose the appropriate facilities in the system by using the AHP(Analytic Hierarchy Process) and analyse the operating efficiency of the new system by simulation. The new suggested system shows about $39.25\%$ improvement in throughput and 3.75 times reduction of manpower compared to the current system.

This study suggests quantitative guidelines for inside clothing temperatures to improve the heat tolerance of 20's females in summer. First, the inside clothing temperatures ($T_{cl}$) of each subject was measured in daily use. The subjects were asked to record subjective thermal sensations, clothing items worn, clothing weight, and activities during an experiment designed to determine the comfort zone of $T_{cl}$. In a thermally neutral state, the comfort zone of $T_{cl}$ was decided on a mean value $T_{cl}{\pm}1{\sigma}$. Second, the subjects were asked to wear clothing that would enable them to feel 'slightly warm but still comfortable'. The rest of the processes were the same as previous steps that were designed to understand the way and degree of clothing control. The comfort zone of $T_{cl}$ was decided in the same manner as the previous step. The two comfort zones were combined and named the combined comfort zone of the definitive comfort zone. The results were as follows: 1. Thermally comfortable $T_{cl}$, Hcl were $34.0{\pm}1.1^{\circ}C$, $40{\pm}9%%RH$ and the thermally comfortable ambient climate was $25.0{\pm}1.6^{\circ}C$, $53{\pm}7%$RH. 2. When subjects were asked to wear 'slightly warm but still comfortable', there were difference in thermally comfortable $T_{cl}$, clothing weight and clothing layer by subject. 3. In this study, the optimal $T_{cl}$ was decided on the mid-point of the definitive comfort zone of $T_{cl}$.

In this study, we examined the new ensemble training approach to reduce the systematic error and improve prediction skill of wind by using the Short-range Ensemble prediction system (SENSE), which is the mesoscale multi-model ensemble prediction system. The SENSE has 16 ensemble members based on the MM5, WRF ARW, and WRF NMM. We evaluated the skill of surface wind prediction compared with AWS (Automatic Weather Station) observation during the summer season (June - August, 2006). At first stage, the correction of initial state for each member was performed with respect to the observed values, and the corrected members get the training stage to find out an adaptive weight function, which is formulated by Root Mean Square Vector Error (RMSVE). It was found that the optimal training period was 1-day through the experiments of sensitivity to the training interval. We obtained the weighted ensemble average which reveals smaller errors of the spatial and temporal pattern of wind speed than those of the simple ensemble average.

This paper introduces a GP(Genetic Programming) based robust technique for temperature compensation in short-range prediction. Development of an efficient MOS(Model Output Statistics) is necessary to correct systematic errors of the model, because forecast models do not reliably determine weather conditions. Most of MOS use a linear regression to compensate a prediction model, therefore it is hard to manage an irregular nature of prediction. In order to solve the problem, a nonlinear and symbolic regression method using GP is suggested. The purpose of this study is to evaluate the accuracy of the estimation by a GP based nonlinear MOS for 3 days temperatures in Korean regions. This method is then compared to the UM model and has shown superior results. The training period of 2007-2009 summer is used, and the data of 2010 summer is adopted for verification.

The purpose of this study was to serve as a basis for better student practice in dental hygiene and for determining educational direction for dental hygiene clinical education by examining what students and clinical-practice instructors thought on clinical practice and what factors gave an impact to clinical education. For attaining the purpose, an investigation was made of 449 third-grade students in the department of dental hygiene at seven educational institutes in Seoul and Kyoung-gi province. 246 instructors in charge of the clinical practice of the students at dental hospital or clinics were also examined. The findings of this study were as follows: 1. The instructors and students had different opinions on the number of trainees, training time, beginning of training, and assessment(p<0.05). The instructors thought that a trainee was appropriate for an instructor(59.8%), and that training time was not sufficient(30.8%). They considered it proper for students to start practice during the summer vacation of second year(21.5%), and responded that assessment should be done by the dentist, dental hygienist or professor in charge(44.7%). However, the students had an idea that an instructor should take charge of 2 or 3 trainees(47.4%), and that there was a lot of training time(55.7%). They considered it appropriate to start practice in the first term of second grade(l9A%), and thought the assessment should be made by the dentist and dental hygienist in charge(44.8%). 2. The students' satisfaction was clinical practice was affected(p<0.05) by their own selection of training institutes(28.1%), the absence of trainee from other colleges(29.4%), ample practice time(28.3%), implementation of student assessment once a day(45.3%), diverse practice opportunities (45.5%), and easy traffic to the training institute(32.9%). 3. The achivement of clinical practice was influenced by practice opportunities, the degree of faithful treatment performance, the frequency of student assessment, the number of trainees, traffic to training institutes, assistance in understanding theoretical knowledge of clinical practice, and assessment methods(p<0.05).

The COVID-19 Pandemic, which began in 2020, has led to many changes in the Korean church. It created a situation in which not only the change and form of worship time, but also the definition, direction, and philosophy of ministry had to be re-established. In the early days of COVID-19 Pandemic, the Korean church recognized this as a crisis, but gradually regarded these as opportunities and tried to produce positive results. The Department of Education has also undergone many changes, especially in its summer ministry, and is expected to have undergone more dramatic changes in form, location and method than in any other church event or service. However, no accurate data on this has been collected. Accordingly, Mirae with Dreams (CEO: Pastor Kim Eun-ho), a corporation established by the Oryun Church for the next generation of ministry, conducted a survey on the summer ministry of the Korean church, which has been registered as a future member with dreams every year since 2020 when the COVID-19 fan dummy began. A similar survey was conducted in 2022 following 2021, and 260 churches responded, and the results are as follows. In 2022, the summer ministry of the Ministry of Education of the Korean Church returned to the form before the COVID-19 Pandemic. Unlike 2021, when many of them were held online, more than 81 percent said they had conducted summer camps offline, and 31 percent also conducted or attended outdoor camps. In terms of the importance of roles, when online was also the main focus, parents and teachers were equally viewed or emphasized, while in this summer's survey, 90 percent of respondents said that the role of teachers in charge or department was important. Summer events were mainly summer Bible schools and retreats, but 25% of all respondents said they conducted missionary work and evangelism at home and abroad. Compared to 2021, participation in summer camps has increased in all departments, including infant and kindergarten, elementary and middle school, and especially in infant and middle school. While preparing for the summer camp, most of the respondents said that the focus was on content and topics, and the main focus was on children's accessibility compared to 2021. As a result of synthesizing the description of the reason for the respondents who could not conduct the summer camp, about 40% said they could not conduct the summer camp due to a lack of volunteers. This is more than 30% who pointed out COVID-19 as the cause, which can be seen as an urgent problem to be solved at the Korean church and denomination level. In addition, this paper also mentioned detailed changes in each question, referring to the changes in summer camps from 2020 to 2022.

At present, the students majoring in tourism apprach theoretically and practically target human resource development which is blanceded between creativity and specialty. And yet, the initial step of on-the-job tranning has not been worked and the area of tourism and experience in this field are know as a beginning stage. This, this study is focusing on the on-the-job tranning in the area of tourism major in technical college. The issues and alternative solutions are as follows First, many student hope sutible training cost require. Second, An amount of subsidy for trainee is too low, and a trainee is used as substitution for regularem ployee's vacation during summer season and for beginning and end of year during winter season. Third, There is no clear linkage between job training and employment. Forth, many students enter a technical college due to learn professional technique and service, however, many other students go to a technical college as means of transfer to university, Since a tourism bussiness is predicted as a potential industry for the twenty-first century, besides a positive national economy and tourism business, the continuing and active supports and needed as follows First, An active support on tranning provided by tourism companies is required. Second, A continuos driving force and thorough management of job training by technical college and relevant major department are needed. Third, sutible traninging cost would be required. Forth, In order to achive a objectives and practical and effect ive job tranning, students majoring in tourism should enhance a service mind and manner.
