This study investigates the interference of politics of regional cleavage in the redistricting for national assembly election and its effects on gerrymandering and malapportionment. Since the Constitutional Assembly election, the argument about gerrymandering and malapportionment continues and the single-member election district with simple plurality system in Korea has aggravated the problem of cleavage and unfairness. Especially, redistrictings for national assembly election in 2008 and 2012 are suspected of gerrymandering by Saenuri party and Democratic United party. Yeongnam region where Saenuri party is dominant and Honam region where Democratic United party is, are over-represented compared to population, while the districts in Gyeonggi-do are under-represented and the need for increasing the number of districts has been ignored. These redistrictings might come from unfair and collusive interference of politics of regional cleavage, and consequently malapportionment has been brought about.

홍수 시 하천을 따라 유하되는 유송잡물(잡목, 생활쓰레기 등)은 구조물에 집적이 이루어지며 이로 인해 물의 흐름을 방해하고 구조물 주변의 지반을 약화시키거나 월류로 인해 심각한 피해를 야기 시킨다. 교량의 경우 유송잡물의 집적은 교각의 항력을 증가시켜 전도파괴를 유발시킬 수 있으며, 교각주변 흐름교란을 통한 하상세굴로 인해 기초부를 파괴시키기도 한다. 또한 통수단면적 증가로 인해 높아진 수위는 제방을 월류시켜 재산 및 인명피해를 유발하기도 한다. 암거의 경우 유송잡물을 포함한 토사로 인해 단면폐색 및 침식으로 암거의 파괴를 발생시키고 이로인해 도로의 단절을 가져오기도 한다. 이러한 유송잡물에 대한 차단대책은 현재 까지 유지관리를 통한 방법만이 최선책으로 제시되고 있다. 본 연구는 국외에서 소개되고 있는 유송잡물 피해저감시설을 대상으로 축소모형실험을 통해 효과를 확인하고 이를 통해 저감시설의 효율에 대해 소개하고자 하는 것이 주목적이다. 유송잡물 저감시설은 교량의 경우 수직분리대 방법, 우회말뚝 방법, 스위퍼를 이용한 방법으로 소개하고 있으며 이들 방법의 특징은 유송잡물 우회를 통해 집적을 저감하는 방식이다. 암거의 경우 수직분리대 방법, 스크린 방법, 우회스크린을 이용하는 방법 등이 있으며 수직분리대는 교량과 마찬가지로 우회방식을 기본방식으로 스크린 방식은 유송잡물의 차단을 원칙으로 하고 있다. 실험의 결과는 교량과 암거의 차단시설 유무에 따른 유송잡물의 집적률을 대상으로 하였다. 차단시설이 없는 경우 교량에서의 집적률은 97.9% ~ 99.2%의 집적률로 나타났다. 수직분리대의 경우 유송잡물 집적률은 49.3%, 우회말뚝은 0.0% ~ 4.2%의 범위로 매우 높은 차단효과를 보이고 있었다. 스위퍼방식의 경우 집적률은 5.3% ~ 20.9%로 나타났다. 이러한 결과로 판단하였을 때 차단시설 설치로 인한 교량에 대한 직접적인 차단효과는 수직분리대 < 스위퍼 < 우회말뚝 순으로 높은 차단효과를 보이는 것으로 나타났다. 그러나 우회말뚝에서의 집적률이 한계치를 넘어선다면 유송잡물로 인해 흐름교란, 수위 및 하상변동, 말뚝의 유실 등으로 인한 피해가 예상된다. 암거대상 유송잡물 차단시설 실험결과는 수직분리대의 경우 type과 투하방법에 따라 차이가 있지만 집적률은 14.7% ~ 64.9%의 범위로 나타났다. 스크린과 우회스크린 방식은 유송잡물의 우회가 아닌 차단이 목적이므로 유송잡물 집적에 의한 수위상승이 우려되는바 수위영향을 검토하였다. 검토결과 스크린 설치로 인한 수위상승이 우회스크린보다 높게 상승하는 것으로 나타났다. 이러한 결과는 스크린의 형태적인 측면에서 2면을 통해 집적되는 특성을 갖는 우회스크린이 통수단면적을 많이 확보하기 때문이다. 따라서 국부적인 수위상승으로 인한 피해를 저감하기 위해서는 설치여건이 허용된다면 통수단면적 확보가 유리한 우회스크린 설치가 유리할 것으로 판단된다.

In December 2020, the Fair Trade Act related to South Korea's separation of industrial capital was amended, and it was announced that the amendments would come into effect one year later, on December 30, 2021. The amendment's content involved breaking the previous principle of separating industrial capital from financial market penetration, allowing for the ownership of shares in general holding companies, small business startup investment companies, and technology business finance specialist companies. While the previous law was based on total issued shares' ownership, there were fluctuations in the subsequent trends of annual establishment and investment counts, as well as strategic investment counts of CVC (Corporate Venture Capital) before and after the law's amendment. CVC and IVC (Independent Venture Capital) are characterized differently based on their investment purposes, fund management types, and investment types. In this regard, the relaxation of the separation of industrial capital law is expected to have a positive impact on the future of the venture investment ecosystem and innovation ecosystem. In this study, we analyze the trends in the establishment count, investment count, and strategic investment count of domestic CVC from 2018, before the law amendment, to May 2023. Using 2021, the year the amended separation of industrial capital law was implemented, as a reference point, we examine changes in the trend. The analysis results indicate a significant increase in domestic CVC in 2021 compared to the previous year, along with an increase in investment counts, strategic investment counts, and the amount of investment in strategic investments. Based on these findings, this study suggests directions for further research related to future domestic CVC investment, strategic investment, and the activation of the venture investment market.

Transparency on the Total System Performance Assessment (TSPA) is the key issue to enhance the public acceptance for a permanent high level radioactive repository. To approve it, all performances on TSPA through Quality Assurance is necessary. The integrated Cyber R&D Platform is developed by KAERI using the T2R3 principles applicable for five major steps in R&D's. The proposed system is implemented in the web-based system so that all participants in TSPA are able to access the system. It is composed of FEAS (FEp to Assessment through Scenario development) showing systematic approach from the FEPs to Assessment methods flow chart, PAID (Performance Assessment Input Databases) showing PA(Performance Assessment) input data set in web based system and QA system receding those data. All information is integrated into Cyber R&D Platform so that every data in the system can be checked whenever necessary. For more user-friendly system, system upgrade included input data & documentation package is under development. Throughout the next phase R&D, Cyber R&D Platform will be connected with the assessment tool for TSPA so that it will be expected to search the whole information in one unified system.

Successful weaning is very important to provide adequate nutrients for normal growth and to induce a good diet habit. We conducted a survey on the knowledge and attitudes of women who live in Taegu toward weaning in infants, to figure out how much they know about weaning diet for the infants, which source they prefer to get the information about weaning diet, whether their knowledge affect their practice about weaning in infants, and the most effective way to educate them. A survey was conducted with the prepared questionnaire on women who responded at the residential area and market place, and those who visited Department of Pediatrics, Yeungnam University Hospital from July 25 to September 15, 1997. Statistical analysis was done with student t-test and ANOVA using SPSS program. Among total 303 responders, those who aged between 30 and 39 years were 37.2%. Scores for the six questions about weaning policy showed highest in the age group between 30 and 39 years. Higher score was recorded in the more educated group, in those who get informations about weaning diet from books, magazines and pediatricians. The majority of the responders had wrong concepts, such as feeding weaning diet using bottle(69.1%), feeding mixed with formula in the same bottle(64.5%), addition of salt(68.4%). Those who had higher educational level preferred books, magazines rather than neighbors or mother to get informations about weaning diet. Those who preferred books or magazines started weaning, stopped bottle feeding, and used spoon earlier, and their children had unbalanced diet habits less frequently. Home-made food was used most frequently, and commercial products were used less frequently. Those who were employed preferred home-made food rather than commercial products, it may be caused by the difference of the educational backgrounds from those of the unemployed. In conclusion, most responders ask neighbors and mother to get informations about weaning, and the incorrect knowledge from them could cause inadequate weaning practice and induce bad diet habit in their children. We have to find the reasons why they did not refer books or magazines frequently, and the way to resolve the problem.

This study attempts to examine standards on the effectiveness of the rights to social security of people with disability. The current research makes the standards on effectiveness of social security rights to the disabled. This standards draw four right areas and five general principles from debates about effectiveness of general social security rights and extend for applying three social area to the disabled. Four right areas are benefit coverage, benefit structure, benefit restriction and rights relief. Five general principles are enforceable rule principle, national finance principle, unconditional principle, adequacy principle and penalties principle. These four right areas and five general principles apply to three social security areas of income support, employment security and medical security. Measurement values are 'high' and 'low'. These measurement values divided into two that are used to ensure same intervals. This study on standards to the effectiveness of the rights to social security of people with disability has political and theoretical implications. First, in political aspects, these standards provide objective understanding of the present level of social security policies for the disabled. Second, theoretically the current study expands debates about the effectiveness of general social security through multi-disciplined research. At once this study is significant to establish empirical research foundation.

A theory and method on the economic allocation of a limitted amount of fertilizer to different crops which show different responses to the application of fertilizers was discussed. If the amount of fertilizer is not enough for all the crops which a farmer plans to grow, the fertilizer should be shared among the crops so as to maximize his profit from all his crops. According to the theory and method discussed here 9.14, 7.11 and 8.75kg per ha./10 of nitrogen should be allocated to rice, barley and wheat instead of 10, 7.5 and 7.5kg per ha./10 which were the amount allocated by the Government of Korea in 1968. The theory could also be with advantage applied to the planning of national fertilizer allocation.
