Supercomputers have played an important role in various fields such as science, industry, national security and solutions for social issues, and their demand is increasing significantly as their use is strengthened in areas using big data and AI. Recently, competition for global exascale system development is accelerating based on various architectures, and the era of exascale computing is expected to come in the near future. However, the foundation of the domestic supercomputing ecosystem was lost due to the decline of the server industry in the past, and although the related law was enacted to supplement and foster it, it has not been able to perform its function smoothly. Therefore, this article examines the problems in the current legal system through the analysis of the relevant legal system and the status of the supercomputing ecosystem, and suggests improvements so that the relevant legal system, which can accommodate the reinforcement of the role of the government·national center·professional center, support for industries, promotion of commercialization of research results, and flexibility of government promotion policies, can prepare the basis for the promotion of the supercomputing R&D project.

It is a time when a sustainable Korean Culture Festival strategy is needed. The Korean Culture Festival is a Hallyu Culture Festival that comprehensively introduces various Korean cultures such as Korean food, beauty, and fashion with the focus on K content, which has been leading the global craze since 2020. As the core project of the promotion of Neo Hallyu by the Ministry of Culture and Gymnasium, the 2021 Korean Culture Festival, which was based on the World K-Pop concert and the K-Culture Fan Fair, including holding the first face-to-face concert that applied the stage of real-world content after Covid-19, as well as conducting and exhibiting various fan participation challenges, must now make the leap to the global Hallyu Culture Festival. To this end, it can consist of drama, K-pop, K-Culture Fan Fair, K-Meetup, K-Culture Parade, and Awards. This distinction shows a classic festival program centered around the prosumer content that drives the Korean Wave, and in order for this philosophy to be effectively linked to its contemporaries, a Business to Business (B2B) and Business to Consumer (B2C) 'Techtainment Strategy' is needed to acquire potential customers through learned playfulness.

Since R&D (Research and Development) of small companies is becoming more and more important, and government R&D grants are still increasing. This study aims to investigate the factors influencing R&D performance of small companies and necessary capabilities of them. Based on empirical study of 3,636 small companies which participated and completed government R&D grant project, technology innovation capability and technology commercializing capability of small companies are positively related with organizational competences, with moderating effects of entrepreneurship. In addition, their R&D capabilities are not significantly related with R&D commercializing performance directly, but mediated with organizational competences. The results of study suggest implications of measuring the R&D performance of small companies and government support policy with the importance of organizational competences as an intermediate variable of R&D performances.

Objectives: The purpose of this study is to standardize the process code of the work environment measurement database (WEMD) for the construction of a job-exposure matrix (JEM). Methods: The standard process code (SPC) was reclassified based on process similarity and drawing upon the code used in the existing K2B. It was supplemented through review by industrial hygiene experts. In addition, an index word database related to SPC was created and used for SPC search. A pilot evaluation project was conducted by experts to evaluate the validity of the newly reclassified standard process code. Results: A total of 70 final SPCs were developed, including 31 processes related to the construction industry. Using the Shiny program, we developed a standard code finder that can be used on the web (https://kscf.shinyapps.io/scf_app/). As a result of the pilot evaluation, it was determined that it was easier to search for standard codes than previous codes, so it was highly utilized. Conclusions: It is expected that JEM construction using industry-process information drawing on WEMD data will be possible using the 70 newly standardized process codes.

The estuary reservoir is a major source of agricultural water in Korea; for effective and sustainable water resource management of the estuary reservoir, it is crucial to comprehensively consider various water resource factors, including water supply, flood, and pollutant management, and analyze future runoff changes in consideration of environmental changes such as climate change. The objective of this study is to estimate the impact of future climate change on the runoff characteristics of an estuary reservoir watershed. Climate data on future Shared Socioeconomic Pathway (SSP) scenarios were derived from two Global Climate Models (GCMs) of the Coupled Model Intercomparison Project phase 6 (CMIP6). The Hydrological Simulation Program-Fortran (HSPF) was used to simulate past and future long-term runoff of the Ganwol estuary reservoir watershed. The findings showed that as the impact of climate change intensified, the average annual runoff in the future period was higher in the order of SSP5, SSP3, SSP1, and SSP2, and the ratio of runoff in July decreased while the ratio of runoff in October increased. Moreover, in terms of river flow regime, the SSP2 scenario was found to be the most advantageous and the SSP3 scenario was the most disadvantageous. The findings of this study can be used as basic data for developing sustainable water resource management plans and can be applied to estuary reservoir models to predict future environmental changes in estuary reservoirs.

In order to facilitate the Korean government's efforts in integrating family planning and maternal & child health at the primary health care level (or township level), the Soon Chun Hyang College of Medicine, with the financial and technical assistance of WHO, has under-taken a service research project. The project has employed a quasi-experimental study design introducing interventions tat provide crucial factors lacking in the ongoing government programs such as midwives and qualified referral physicians. The study is being conducted in three locations, one control area and two study areas. Before introducing trained Nurse/Midewives into the study areas, a baseline prevalence survey was undertaken from 15 July 1981 to 10 August 1981 in selelcted townships of Seosan County. In this sample survey of bath the study and control areas, 2,484 eligible women (97% reponse rate) were interviewed to obtain benchmark data on basic evaluation indicators related to family planning and maternal and child health. The salients results were summarized as follows.: 1. CONTACT RATES WITH HEALTH WORKERS; During the year preceding the survey, 12% of women were visited by government health workers. The primary reason for such visits by health workers was family planning (45% of the visits). About 34% of the women visited the health centers during the year. The primary reason for visiting health centers was immunizations for their children (45% of the visits). 3. FAMILY PLANNING USE RATE; The baseline data showed little difference between women in the study area and the control area on contraceptive use. Approximately 59% were currently using some methods. However, among those current users, almost half were practicing less effective methods of birth control such as rhythm or withdrawal. Among other methods, the tubectomy was the most popular (16%), while use of the IUD, oral pill and condom together reached only 14%. 3. PRENATAL CARE RATE; About 75% of the women reported no prenatal care for their last births (the youngest child of each women), Additionally, among women received prenatal care, over half had only one visit. 4. ATTENDANCE AT DELIVERY; Most of the women surveyed (over 80%) were attended by a non-medical person during their last delivery. These figures are somewhat comparable to the national figure of 84% for remote areas. 5. POSTNATAL CARE; The proportion of women reporting postnatal care was only 4.5%, and postnatal care was not received by the majority of women surveyed. 6. CHILD HEALTH CARE: In contrast to the low rate of maternity care for women themselves, most women reported obtaining immunization care for their children. About 75% of the women obtained Polio and/or DPT, 58% BCG, and 44% Measles vaccine for their children. However, in terms of illness care, while 35% of the women stated that their youngest child had been sick during the month preceding the survey, only 28% of these women took their child to the clinic for treatment. 7. COMPLICATIONS OF PREGNANCY AND DELIVERY AND ABNORMALITIES IN THE NEWBORN; Among all last deliveries, 18% of the women had pregnancy complications and 9% of the women had complications during delivery About 5% of the women reported abnormality in their most recent newborn. 8. REPRODUCTION EFFICIENCY; PERINATAL MORTALITY AND INFANT MORTALITY Based on data from the pregnancy history in this survey, reproduction efficiency was estimated. Out of the 11,154 pregnancies reported by all women surveyed, foetal loss was 21% (almost 16% were induced abortions) and infant deaths before reaching one year old were 3.1%. The reproduction efficiency was, therefore, reduced to 76%. In terms of perinatal and infant mortality rates, the former was 40.2 per 1,000 total births and the latter was 39.3 per 1,000 live births. Both rates described J shaped relationships with age of mothers and parity, and they were also correlated with birth interval and mother's education. In summary, this baseline survey data indicated a need for (1) improving contraceptive practices with more effective methods to prevent unwanted pregnancies and (2) providing better services for maternal and child care to protect wanted pregancies. In the Korean rural setting. the author believes that the latter is more important as the value of each child has increased as a result of the family planning campaign for the past two decades. This calls for more effective integration of Family Planning and MCH programmes to meet the needs of the family in each stage of the child bearing and rearing period with deploying more qualified personnel than the current government program personnel.

The purpose of this study was to develop and evaluate pre-parenthood education program(PPEP) based on Home Economics(HE) subject for high school students. The development and evaluation of PPEP based on HE subject in this study followed ADDIE model except implementation through 4 processes such as analysis, design, development, and evaluation. First, program development directions were set in three aspects such as 'general development', 'contents', and 'teaching and learning methods'. Themes of the program are 11 in total such as '1. Parenting, what is being a parent', '2. Choosing your spouse, happy marital relationship, the best gift to your children', '3. Pregnancy and birth, a moving meeting with a new life', '4. Taking care of a new born infant for 24 hours', '5. Taking care of infants, relationship with my lovely baby, attachment', '6. Taking care of young children, my child from another planet', '7. Parents and children in healthy family', '8. Parent-child relationship, wise parents to make effective interaction with their children', '9. Parents safety manager at home,', '10. Practice to take care of infants', and '11. Practice of community nurturing support service development'. In particular, learning activities of the program have major characteristics such as 1) utilization of cases including practice problems related to parenting, 2) community exchange activities utilizing learned knowledge and techniques, 3) actual life project activities utilizing learning contents related with parenting, 4) activities inducing positive changes in current life of high school students, and 5) practice activities for the necessities of life such as food, clothing and shelter supporting development of children. Second, the program was developed according to the design. Teaching-learning plans and materials for 17 classes were developed according to 11 themes. The developed plans include class flow and teacher's reference. It starts with receiving a class-related message from a virtual child at the introduction stage and ended with replying to the message by summarizing contents of the class and making a promise as a parent-to-be. That is the basic frame of class flow. Learning materials included various plans and reports necessary for learning activities and they are prepared in details so that they can be play the role of textbooks in regular curriculum. Third, evaluation of developed program was executed by a 5 point Likert scale survey on 13 HE experts on two aspects of program development process and program development results. In the evaluation of development process, mean value was 4.61 and index of content validity was 97.4%. For development results, mean value was 4.37 and index of content validity was 86.9%. These values showed that validity in the development process and results in this study was highly secured and confirmed that PPEP based on HE was appropriate and valid to enhance parent qualifications of high school learners.

This study introduces newly implemented geological well logs database for Jeju public water wells, built for a research project focusing on integrated hydrogeology database of Jeju Island. A detailed analysis of the existing 1,200 Jeju Island geological logs for the public wells developed since 1970 revealed six major indications to be improved for their use in Jeju geological logs DB construction: (1) lack of uniformity in rock name classification, (2) poor definitions of pyroclastic deposits and sand and gravel layers, (3) lack of well borehole aquifer information, (4) lack of information on well screen installation in many water wells, (5) differences by person in geological logging descriptions. A new Jeju geological logs DB enabling standardized input and output formats has been implemented to overcome the above indications by reestablishing the names of Jeju volcanic and sedimentary rocks and utilizing a commercial, database-based input structured, geological log program. The newly designed database structure in geological log program enables users to store a large number of geology, well drilling, and test data at the standardized DB input structure. Also, well borehole groundwater and aquifer test data can be easily added without modifying the existing database structure. Thus, the newly implemented geological logs DB could be a standardized DB for a large number of Jeju existing public wells and new wells to be developed in the future at Jeju Island. Also, the new geological logs DB will be a basis for ongoing project 'Developing GIS-based integrated interpretation system for Jeju Island hydrogeology'.
