Analysis research was conducted on the 'Chosen Ilbo,' 'Donga Ilbo,' 'Hankyoreh' and 'Kyunghyang Newspaper' on news reporting frame and sources regarding the North Korean population's living and status of their respective conditions throughout South Korean administrations of Kim Dae-jung, Roh Mu-hyuen, and Lee Myung-Bak. Resulting first and second frame analyses showed that the four newspapers showed clear distinctions in their execution and attitude in their reports in accordance to the philosophies of each 'progressive/left-wing newspapers' and 'conservative/right-wing newspapers'. Moreover, the first and second analyses showed that the reports mimicked each individual presidential administration and their political policy regardless of the newspaper's political voice. In terms of the usage of 'anonymous sources,' conservative newspapers were found to use them more frequently than their counterpart, the liberal newspapers. In conclusion to the overall analyses, with the continued tension between the International community and North Korea, the reports of North Korean inhabitant activities are inevitably portrayed in a negative tone in effort to plant a distorted view to the South Korean citizens. Furthermore, this manipulation of the press may affect the credibility of South Korean press in terms of the topic of North Korean culture.

The purpose of the present study is to evaluate the usage of microtremor in estimation of subsurface structure and ground response to strong ground motion. To accomplish the purpose, the current status of microtremor study are reviewed and microtremors recorded at several stations are analysed. First of all, the stability of microtremor is examined through the analysis of microtremors recorded for 80 seconds per hour during the time from 10 p.m. to 6 a.m. for eight hours at night time. It is found that the shape of microtremor spectra of low frequency below 10Hz is approximately invariable with time and the spectra contain informations about subsurface structure. The subsurface structures estimated from the predominant frequency determined from the recorded microtremors are compared with the known ones from geophysical surveys at several stations in Kyungju. The comparison of structures shows rough agreements at most stations. Horizontal to vertical spectral ratio(HVSR) technique for microtremor has been proposed as an indirect method to determine ground response to strong ground motion. The HVSR for microtremors recorded in Kyungju is calculated and compared with theoretical transfer function calculated from the known structures. The comparison shows rough coincidence of the peak frequency of spectra between them.

This study investigated the status of drinking highly caffeinated beverages by Korean adolescents, and we identified the factors influencing this behavior by Korean adolescents by using statistics from the 13th (2017) Survey on Youth Health Behavior Online Survey. The data was collected from 62,276 middle and high school students and the variables of this study included demographic factors, health behavioral factors, mental health factors and the availability of highly caffeinated beverages. The methods of data analysis included descriptive statistics, Chi-square tests and logistic regression analysis. This study found that the intake rate of highly caffeinated beverages was 1.9% for men and 1.5% for women, and these percentages increased with age (p<0.001). Current smoking and drinking, current drug usage and active people also had high intake of caffeinated beverages (p<0.001). A high level of stress, a low level of subjective sleep satisfaction and a feeling of happiness increased the rate of consuming highly caffeinated beverages. The factors of drinking highly caffeinated beverages were gender, age, smoking, physical activity, drug use, stress level, depression and suicidal ideation. Therefore, continuous discussion is needed to improve both the health behavior and mental health by managing the stress felt by Korean adolescents.

In order to increase its performance, NAND flash memory-based storage is composed of data buses that are shared by a number of flash memories and uses a parallel technique that can carry out multiple flash memory operations simultaneously. Since the storage performance is strongly influenced by the performance of each data bus, it is important to improve the utilization of the bus by ensuring effective scheduling of operations by the storage controller. However, this is difficult because of dynamic changes in buses due to the unique characteristics of each operation with different timing, cost, and usage by each bus. Furthermore, the scheduling technique for increasing bus utilization may cause unanticipated operation delay and wastage of storage resource. In this study, we suggest various dynamic operation scheduling techniques that consider data bus performance and storage resource efficiency. The proposed techniques divide each operation into three different stages and schedule each stage depending on the characteristics of the operation and the dynamic status of the data bus. We applied the suggested techniques to the controller and verified them on the FPGA platform, and found that program operation decreased by 1.9% in comparison to that achieved by a static scheduling technique, and bus utilization and throughput was approximately 4-7% and 4-19% higher, respectively.

The purpose of this study was to assess the need for nutritional education in male workers living in Busan, Korea. This study surveyed 310 industrial workers at five companies in Busan using a questionnaire. According to the results, need for nutritional education scored 3.60/5.00 points. The usage rate of mass media as a means of acquiring nutritional information was significantly higher (P<0.001) in subjects in their 50s compared to other age groups. Regarding scores on need for nutritional education according to theme, 'balanced eating habits' showed the highest score, followed by 'food safety', 'diet therapy related to a disease', and 'food hygiene and food poisoning prevention'. In terms of frequency of nutritional education, 29.0% of subjects considered 'biannually' to be desirable, whereas 25.8% and 21.0% considered 'annually' and 'quarterly' to be desirable, respectively. The results of this study suggest that nutritional education for industrial workers should be implemented in various ways in accordance with their characteristics. Furthermore, considering workers' low awareness levels of the need for nutritional education, employees are required to take the education in order to encouraged to improve their nutritional status and commit to a desirable diet.

The existing Extracorporeal membrane oxygenation(ECMO) and Cardiopulmonary bypass system(CPB) have been developed and applied to various devices according to their respective indications. However, due to the complicated configuration and difficult usage method, it causes inconvenience to users and there is a risk of an accident. Therefore, smart all-in-one cardiopulmonary circulation device is being developed recently. The smart all-in-one cardiopulmonary assist device consists of a blood pump for cardiopulmonary bypass, a blood oxidizer for cardiopulmonary bypass, a blood circuit for cardiopulmonary bypass, and an artificial cardiopulmonary device. It is an integrated cardiopulmonary bypass device that can be used for a variety of purposes such as emergency, intraoperative, post-operative intensive care, and long-term cardiopulmonary assist, combined with CPB used in open heart surgery and ECMO used when patient's cardiopulmonary function does not work normally. The smart all-in-one cardiopulmonary assist device does not exist as a standard and international standard applicable to advanced medical devices. Therefore, in this study, we will refer to the International Standard for Blood Components, the International Standard for Blood, the Guideline for Blood Products, and prepare applicable performance and safety guidelines to help quality control of medical devices, and contribute to the improvement of the health of people. The guideline, which is the result of conducted a survey of the method of safety and performance test, is based on the principle of all-in-one cardiopulmonary aiding device, related domestic foreign standards, the status of domestic and foreign patents, related literature, blood pump(ISO 18242), blood oxygenator (ISO 7199), and blood circuit (ISO 15676) for cardiopulmonary bypass.The items on blood safety are as follows: American Society for Testing and Materials ASTM F1841-97R17), and in the 2010 Food and Drug Administration's Safety Assessment Guidelines for Medical Assisted Circulatory Devices. In addition, after reviewing the guidelines drawn up through expert consultation bodies including manufacturers / importers, testing inspectors, academia, etc. the final guideline was established through revision and supplementation process. Therefore, we propose guidelines for evaluating the safety and performance of smart all-in-one cardiopulmonary assist devices in line with growing technology.

The National Fire Safety Code (NFSC) sets forth the installation methods and technical standards of firefighting facilities. This information is stipulated in the attached Table 1 of the Enforcement Decree of the Act on Fire Prevention and Installation, Maintenance and Safety Control of Fire-Fighting Systems. The NFSC serves as a foundation for fire prevention and public safety. However, the current version of the NFSC has been under scrutiny due to its delayed enactment and revision process. This is because of its structural inflexibility, time-consuming procedures, and mixed usage of both performance and technical standards. Furthermore, there are difficulties with keeping its unique specialties due to the absence of a specialized, permanent independent entity that enacts, revises, and maintains its standards. Moreover, the NFSC lacks collectivity, openness, and consistency. Therefore, to overcome the aforementioned obstacles, this study investigates the operational and legal status of the NFSC and the problems regarding its enactment and revision process. Further, it presents suggestions for system improvement by analyzing and comparing the information with domestic and foreign counterparts dedicated to managing their similar technical NFSC standards. First, the study recommends that the legal performance and technical standards mixed within the current NFSC should be separated. Second, the enactment and revision of technical standards should be implemented by the private sector and not by the government. Third, technical standards should adopt a user-oriented approach for the code system.
