With the increase of the establishment of temporary institutions in accordance with social issues, the importance of managing records that reflect the characteristics of temporary institutions is highlighted. However, because of the ambiguity of laws related to records management, the limited number of employees, and the lack of awareness of records management by temporary institutions, the records management has not been carried out properly. Therefore, this study seeks to identify the gaps between statutes and practices and derive improvement measures for them. As such, the concept and characteristics of temporary institutions were identified through requests for disclosure of information. Moreover, the status of the administrative committee and the records management status of various temporary organizations were determined as well. Finally, improvement measures were drawn and proposed in terms of law, system, and record management by selecting relevant institutions in accordance with the Act and conducting in-depth interviews. This study is significant as it monitored the entire process of managing the records of existing time organizations and will serve as the basis for efficiently managing the future ones.

It is well known that soy isoflavones play beneficial roles in the prevention of chronic diseases such as breast cancer, cardiovascular disease and osteoporosis. However current data are not sufficient for estimating the level of isoflavone intake. To use the urinary isoflavone excretion as a maker of isoflavone intake,26 participants consumed the isoflavone extract capsule (90 mg soy isoplavones/capsule) daily for 3 months. The study compared effects of pre- and post-isoflavone supplement in the following parameters; physical examination, dietary recalls, and urinary isoflavon excretion. The average age, height and weight were 65.7 years, 149.4 cm, and 57.3 kg. Subjects maintained regular diet pattern, and average daily nutrient intakes between pre- and post- supplementation were not significantly different except vitamin A, carotene and vitamin C. There was no significant difference between pre- and post- supplementation in terms of daily isoflavone intake. The basal urinary isoflavone excretion was 8.37 mg/day (daidzein 6.23 mu genistein 2.14 mg), and average daily excretion rate was IS.8%. Urinary isoflavone excretion was significantly increased, after isoflavone supplementation for 3 months as compared the basal level (p<0.01). Our data suggest that urinary isoflavone level, especially daidzein and genistein, may be a useful maker to estimate isoflavone intake.

하천유량자료는 이수, 치수, 수질관리 등의 목적으로 널리 사용되기 때문에 여러 가지 수문관측 자료 중 가장 중요하다고 할 수 있다. 그러나 우리나라의 유량자료는 여러 가지 한계를 가지고 있어서 수문자료로서 제대로 사용되지 못하고 있는 실정이다. 특히 홍수기 부자측정 방법에 의해 산정된 유량자료는 측정 여건, 방법, 기기 등의 한계로 인해 그 정확도가 더욱 낮다. 부자에 의한 유량측정은 일정거리를 유하하는 부자의 유하시간을 측정하여 평균유속을 구하고, 사전에 측량된 횡단면으로부터 유하한 개별 부자의 해당 단면적을 구하여 부분 단면적을 구한다. 구해진 개별 부자의 평균유속과 부분 단면적을 곱하여 부분유량을 산출한 후, 각 부분유량을 합하여 전체 유량을 계산한다. 이와같은 부자법은 유속-면적법이 가지고 있는 흐름 단면적 계산, 평균유속 계산의 불확실도 이외에 유하경로에 의한 불확실도, 부자 유하 시간의 불확실도, 유속 보정 계수의 불확실도 등을 포함한다. 기존 홍수 유량측정에 사용하고 있는 부자법은 육안에 의해 부자의 위치를 파악하고, 가상의 횡단선을 통과할 때 육안으로 관측하여 유하시간을 측정하는 방법이기 때문에 정확한 유량측정에 한계가 있다. 뿐만 아니라 측정에 다수의 인원이 필요하며, 홍수시 많은 비가 내리거나, 야간에 측정하는 경우에는 부자의 식별이 곤란하고 측정 여건이 불량하기 때문에 측정에 큰 애로가 있다. GPS를 이용한 전자부자는 자동으로 유속을 측정하기 위해 기존 홍수유량 측정에 사용하던 부자에 전자장치를 추가하는 것을 말한다. 본 연구에서는 GPS와 RF를 기존 봉부자에 추가하여 봉부자의 유속과 봉부자의 괘적을 측정할 수 있는 전자부자를 개발하였다. 개발한 전자부자는 기존 육안에 의한 방식보다 자동으로 정확한 유속 측정이 가능하며, 동시에 여러 개의 봉부자 사용이 가능하여 측정시간 절감이 가능하고, 비가 내리거나 야간에도 자동으로 측정이 가능한 특징을 지니고 있다. 본 연구에서 개발된 전자부자는 3개 주파수 대역을 이용할 수 있도록 개발하여, 총 15개의 부자를 동시에 투하할 수 있도록 개발하였다. 전자부자 시험결과 50m, 100m 구간 유속을 검증한 결과 50m의 경우 최대 평균 5.97%, 평균 2.38%의 상대오차를 나타냈으며, 100m의 경우 최대 5.43%, 평균 1.9%의 상대오차를 나타냈다. 자연하천 유량측정 결과 댐 방류량 대비 기존방법의 경우 약 8.2%의 상대오차를 지니고 있었으며, 전자부자의 경우 약 2.8% 상대오차를 지니고 있어, 기존 부자법에 비해 전자부자법이 5.4%의 상대오차 개선효과를 지니고 있었다. 이와같은 오차의 범위는 실제 하천에서 전자부자를 이용하여 유속측정이 가능함을 나타내는 결과이다.

Faced with various challenges given from internal or external, universities and colleges, about 300 in number, began to feel one another as their rival and recognized advertising marketing as a solution of unlimited competition and were in serious action for advertising. School advertising has suddenly increased in quantity, but falls in creative strategy of qualitative level behind corporate or product advertising. This study suggests effective creative strategy, based on comprehension of characteristics of school advertising and on analysis of creative as a strategy, of advertisements put by schools. School advertising demands the approach different from commercial dimension of corporate advertising, because schools are characteristic of public interests. Schools need to take positive creative strategy of image advertising instead of passive type of recruitment announcement. This effective and Positive creative strategy des not only Provide the chance to select schools for customers of school advertising which sets up applicants for admission as the first target audience, but also instills affirmative and positive image in potential customers of the future such as pupils of elementary or middle schools and ordinary people so that it may make effective communication possible

In this paper, a real-time public transportation monitoring system is proposed. The proposed system was implemented by developing a public transportation app and utilizing optical sensors, pressure sensors, and an object detection algorithm. Additionally, a bus model was created to verify the system's functionality. The proposed real-time public transportation monitoring system has three key features. First, the app can monitor congestion levels within public transportation by detecting seat occupancy and the total number of passengers based on changes in optical and pressure sensor readings. Second, to prevent errors in the optical sensor that can occur when multiple passengers board or disembark simultaneously, we explored the possibility of using the YOLO object detection algorithm to verify the number of passengers through CCTV footage. Third, convenience is enhanced by displaying occupied seats in different colors on a separate screen. The system also allows users to check their current location, available public transportation options, and remaining time until arrival. Therefore, the proposed system is expected to offer greater convenience to public transportation users.

Purpose: Normal education operation was difficult in the national disaster situation of Coronavirus Infection-19. Non-face-to-face education can be an alternative to face to face education, but it is not easy to provide the same level of education. In this study, the professor of disaster management field will identify problems that can occur in the overall operation and progress of non-face-to-face education and seek ways to improve non-face-to-face education. Method: Non-face-to-face real-time education was largely categorized into pre-class, in-class, post-class, and evaluation, and case studies were conducted through the professor's case studies. Result&Conclusion: The results of the survey are as follows: First, pre-class, it was worth considering providing a non-face-to-face educational place for professors, and the need for prior education on non-face-to-face educational equipment and systems was required. In addition, it seems necessary to make sure that education is operated smoothly by giving enough notice on classes and to make efforts to develop non-face-to-face education programs for practical class. Second, communication between professor and learner, and among learners can be an important factor in non-face-to-face mid classes. To this end, it is necessary to actively utilize debate-type classes to lead learners to participate in education and enhance the educational effect through constant interaction. Third, non-face-to-face post classes, policies on the protection of privacy due to video records should be prepared to protect the privacy of professors in advance, and copyright infringement on educational materials should also be considered. In addition, it is necessary to devise various methods for fair and objective evaluation. According to the results of the interview, in the contents, which are components of non-face-to-face education, non-face-to-face education requires detailed plans on the number of students, contents, and curriculum suitable for non-face-to-face education from the design of the education. In the system, it is necessary to give the professor enough time to fully learn and familiarize with the function of the program through pre-education on the program before the professor gives non-face-to-face classes, and to operate the helpdesk, which can thoroughly check the pre-examination before non-face-to-face education and quickly resolve the problem in case of a problem.

Lifestyle is an important variable to understand consumer behavior because it is a lifestyle that is common to all members of society or some members of society. so In this study, the survey has been performed on adult mobile game users over the age of 20 in Korea and China to evaluate the correlation between lifestyle and will of continuous use of game by mobile game users, and the hierarchical multiple regression analysis has been performed on the collected data by using the statistical package program SPSS 20.0. There were total 212 respondents with the gender ratio of 50:50, and 107 respondents were Korean, and 105 respondents were Chinese. As a result of study, first, regardless of lifestyle, more male and more Chinese respondents showed higher will of continuous use. Second, among mobile game user lifestyles, the challenge-oriented, trend-oriented, conservative, and ostentatious lifestyles could become significant causal variables for the will of continuous use of game. Yet, the influence of such lifestyle was not correlated with individual genders or nationalities. The result of this study will be provided as the basic data to establish the strategic solution for companies and government policies for entrance into the mobile game market of China in the future.

A near miss is an unplanned event that did not result in injury/illness, or property damage, but had potentials to do so. The importance of the near miss has been emphasized by many researchers and organizations. However, only a few studies have quantitatively approached the near miss from the viewpoint of safety culture. The purpose of this study is to investigate the current status of near miss reporting activities in manufacturing workplaces in Korea. It also aims to understand how the activities related with the safety culture and the occurrence of industrial accidents. To this end, a survey was conducted on manufacturing workplaces and the results were analyzed. As a result, there was a marked difference in the perception on near miss according to whether or not the near miss reporting activity was conducted. However, it was found that only 56% of the workplaces were carrying out the reporting activities. It was found that the number of near misses reported varied depending on the reward. Although no correlation could be found between whether or not the near miss reporting activities were carried out and the history of industrial accidents occurred, it was found that safety culture level was hier at the workplaces conducting the activities.
