  • Meiosis is a specialized cell division, essential in most reproducing organisms to halve the number of chromosomes, thereby enabling the restoration of ploidy levels during fertilization. A key step in meiosis is homologous recombination, which promotes homologous pairing and generates crossovers (COs) to connect homologous chromosomes until their separation at anaphase I. These CO sites, seen cytologically as chiasmata, represent a reciprocal exchange of genetic information between two homologous non-sister chromatids. RAD51, the eukaryotic homolog of the bacterial RecA recombinase, plays a central role in homologous recombination (HR) in yeast and animals. Loss of RAD51 function causes lethality in the flowering plant, Arabidopsis thaliana, suggesting that RAD51 has a meiotic stage-specific function that is different from homologous pairing activity.

  • In this study, I investigate how city parks have been created, and what are some characteristics of the location and function of 69 city parks in Tokyo. The city parks in Tokyo have been made in three patterns. The first is planned parks which have been created as a urban facilities considering the scales and types. The second is memorial parks which have been made to memorialize the national monumental event or to preserve natural and cultural resources. The third is public property parks which have been made by occurrence of public vacant land which is resulted from the grant of Royal Garden, restoration of public rented ground, producton of reclaimed land, utilization of dry river bed. The city parks can be classified in five patterns according to distance from CBD and park area. The first is central parks which have historical characteristics strongly. The second is planned parks that are specialized functionally. The third is large scale urban edge parks which are located in the edge of 23-Gu(district) in Tokyo. The fourth is hill parks which have natural characteristics strongly. The fifth is waterside parks that are located along a lake, a pond, a river, or artificial waterside facilities. From this study I have found out that a great effort has been made to activate the utilization of parks for residents in Tokyo, through mnagement goals and ways of parks, composition and chatacteristics of park facility resources, various Events, residents participation in undertaking of parks.

  • This study aims to examine the differences between groups through the results of the core competency diagnosis, and to find out the differences in core competences depending on engineering education accreditation, gender, admission types. To this end, we analyzed the differences in K-CESA results on self-management capabilities, resources & information use, global competency, higher order thinking competency, and interpersonal competency in 2017 for the fourth graders of S University. An ANOVA of major field showed that the humanities had high overall competencies. The results of t-test of engineering students showed that accredited students had relatively low "flexibility" of their global competency, and that the "analysis" of their higher order thinking competency was relatively high. There were no statistically significant differences between groups depending on the admission types. Through these analyses, we presented suggestions such as the provision of specialized programs based on differences among different groups, the development of comprehensive thinking skills such as capstone design, the need to secure flexibility in engineering education accreditation, and the enhancement of female students' resources & information use.

  • Citizen perception is increasingly emphasized as one of the critical factors in establishing public policies including river management. Our results show that citizens expect integrated river management by specialized river management organization. We found that the river condition was perceived more negatively than the actual status of water quality and river ecosystem by citizens. The gap in perception implies that it is important to restore the reliability of river management. Therefore, it is necessary to encourage organizations with public trust to participate in river management. and credible river management policies should be established and implemented.

  • The study attempts to examine the system-building activities of scientific institutions in developing the Molecular Diagnostic (MDs) Innovation System in India. Scientific Institutions are the precursor of any technological development with their capabilities in generating new ideas. MDs are advanced and accurate diagnostic technology with considerable scope to serve the diagnostic needs and requirements of the healthcare system. We adopted a System framework and analyzed the development of MDs in terms of the Technological Innovation System (TIS) functions, and the systematic challenges are assessed through the System Failure Framework (SFF). Based on the secondary and primary survey of prominent science base actors, the study finds that the role of government is crucial for facilitating technological development within a science base through the mobilization of resources. In India, the MDs technological development gained significant momentum over the last decade with the development of specialized human resources and dedicated research institutes. However, we do find that the innovative capabilities in attaining need-based TIS are sub-optimal owning to the specific diagnostic needs of highly burdened diseases in the society. The system analysis reveals that the TIS functions are underperforming because of the absence of a well-defined funding mechanism and goal-oriented targeted policy regime of the government. Since MDs have a transformative effect on the present healthcare system, we argue that the government has to address the system-based challenges and issues for developing a need-based technological innovation system for MDs in the country.

  • We analyzed the diet composition of smallmouth argentine Argentina kagoshimae, which were collected via bottom trawl in the South Sea during February, April, August, and October 2021. Their size range was 8.1-21.4 cm total length. A. kagoshimae are mesopelagic carnivores, mainly consuming benthopelagic Euphausiacea and Caridea crustaceans. Polychaetes were the second largest prey component in their diet, which also included small quantities of copepods, amphipods, and arrow worms. Stomach content compositions substantially differed among body size levels in A. kagoshimae. The results of non-metric multidimensional scaling ordination and permutational multivariate analysis of variance of dietary data revealed no significant dietary differences. The results of a graphical analysis of the diet composition showed that A. kagoshimae are specialized feeders characterized by strong individual feeding specialization.

  • The South Korean military has undergone four changes in operating methods since its inception with 31 nursing officers in August 1948. While it initially began as a special unit for nursing and other specialized services, it later expanded to include various fields including technology, administration, and special forces. However, analysis shows that there have been few significant changes in how it operates and remains largely centered around technology, administration, and special forces. With the development of advanced science and technology and a decrease in military resources, there is a need for the South Korean military to proactively expand its use of female personnel, as has been done by the US military, Canadian military, Israeli military with female conscription, and Norwegian military. In order to achieve this, there needs to be a cultural shift towards co-ed military units, improvements in facilities and equipment, adequate pay and benefits, and resolution of childcare issues through institutional reforms.

  • Object: The purpose of this study was to survey the government official support status of the agricultural diseases, injuries and accidents among Korea and foreign countries and to suggest the agricultural policy of Korea. Methods: For this purpose, we analyzed the current national management support status among four foreign countries and Korea about agricultural diseases, injuries and accidents of farmers. For the foreign countries and the national support current status of agricultural diseases, injuries and accidents, related literature such as books, theses, articles, and web documents from the government organization of each countries were collected and analyzed. Key words for web-site and web documents were agricultural diseases, injuries, and accidents, government official system, safety and health, farmer's welfare, and farmer's official support system. UK, United States of America, France, and Japan were selected as the foreign countries' cases. Results and Conclusions: Implications for the agricultural diseases, injuries and accidents derived from the reviews among foreign countries and Korea were as follows: governmental supports should include (1) efforts on unifying administrative systems, (2) special support and management systems focusing on special subjects such as the agriculture that have been neglected, (3) aligned strategies including vision, goals, long-term plans about national safety and health projects, (4) development of supporting systems considering the features of agriculture, (5) systemized national surveys about occupational injuries and accidents for basic statistics and national studies, (6) active prevention efforts of agricultural diseases, injuries and accidents, and (8) specialized funds for safety and health of Korean farmers.

  • Since some cyanobacterial isolates under selective culturing conditions are lacking of characteristic specialized cells or showing altered morphology, the morpho-taxonomic criteria are not accurate enough to discriminate between species. Instead of morphological parameters, a method based on the single or the combination of repetitive oligonucleotides in a single PCR, repetitive oligonucleotides-primed PCR (ROP-PCR), was applied to generate DNA profiles for members of the cyanobacterial genera Anabaena and Oscillatoria, both of which are responsible for causing poisonous blooms in various freshwater systems. ROP-PCR performed on 10 isolates of the cyanobacteria with ERIC and REP sequences from gram-negative bacteria, STRR1A and LTRR sequences derived from cyanobacterial genome, and eukaryotic repetitive sequences, led to the identification of distinct genotypes, and provided specific and repeatable DNA fingerprints for cyanobacterial isolates. Grouping analysis of cyanobacterial isolates showed a signifiant difference depending on the primer used in PCR.
