Revisioned labour law was confirmed by vote of National Assembly on 1st January 2010. Under revisions labour law the necessity was expressed to reconstruct and change the relationship between labour and management in hospital. This study was described to investigate the operational statement of labour union in general hospital and to investigate how the labour policy would be change and which form would be appear in labour union in hospital. The survey results which was operated targeting labour managers in hospital were as follows ; first, in the possibility of plural labour unions establishment, university hospital labour managers forecasted the possibility as high. but non-university hospital labour managers forecasted the possibility as low. second, even though the plural union labours would be established in hospitals there would be no difficulties in collective bargaining between labour and management. third, the labour union activities would not be shrink even though there would be wage pay prohibition for the full-time union laboures. As the wage pay prohibition acted on the full-time union labours, countermeasures are required as follows; first, there is a possibility that there will be diversity in the form of full-time union labours. It is need to make the criterion of hospital about the limit of full-time labour union members. It is need to make the criterion of labour activities of non-working hour exception. It is need to cope with the diverse demands of labour union which aim to solve the financial burdens. As the plural labour unions are permitted it is need to make countermeasures as follows ; To analyze whether there is a possibility by the establishment of new labour to be plural labour unions. To establish the countermeasures in short-term aspect to make the countermeasures to cope with the establishment of plural labour unions. In long-term aspect to establish labour and management strategies. Henceforth, found on the revisions labour law, it is need to provide in hospitals as follows; first, it is need to prepare labour management policies and substitutes which suitable for plural labour union period. Second, it is need to determine concretely on the related matters of the union labours and to develop the conclusion guidelines which preparing infective criteria. Third, to examine the effects on the hospital organization by organizational forms of labour union which is weak in financial aspect.

Packaging takes an extremely important element of optical module cost due primarily to the added complication of alignment between semiconductor devices and optical fiber, and many efforts have been devoted on reducing the cost by eliminating the complicated optical alignment procedures in passive manner. In this study, we fabricated silicon optical benches on which the optical alignments are accomplished passively. To improve the positioning accuracy of a flip-chip bonded LD, we adopted fiducial marks and solder dams which are self-aligned with V-groove etch patterns, and a stand-off to control the height and to improve the heat dissipation of LD. Optical sub-assemblies exhibited an average efficiency of -11.75$\pm$1.75 dB(1$\sigma$) from the LD-to-single mode fiber coupling and an average sensitivity of -35.0$\pm$1.5 dBm from the fiber and photodetector coupling.

The objective of this study was to determine the microtubule assembly and chromatin configuration during the first cell cycle in bovine oocytes following injection of spermatozoon, sperm head and tail. The microtubule and chromatin configuration was imaged with fluorescent labeled monoclonal ${\alpha}$-tubulin antibody and propidium iodide under laser scanning confocal microscope. Microtubule and chromatin dynamics in bovine oocytes following intracytoplasmic sperm injection (ICSI) were not different from those observed during in vitro fertilization (IVF). Following ICSI, the microtubular aster was observed around sperm midpiece. During pronuclear formation, the sperm aster was enlarged and seen around male and female pronuclei. At mitotic metaphase, the microtubular spindle assemble astral poles and chromosomes were aligned on the spindle equator. At mitosis, asters were concentrated to each spindle pole and they filled the cytoplasm. After injection of the isolated sperm head, the microtubular aster was not seen around sperm head in any cases (0/18). Instead, microtubules were organized from the cytoplasm, which filled the whole cytoplasm during pronuclear apposition. These microtubules seem to move male and female pronuclei. These results suggest that isolated sperm head can develop into normal pronucleus in mature bovine oocytes, and competent to participate syngamy with the ootid chromatin. The functional microtubules following isolated sperm head injection in bovine oocytes appeared to be organized solely from maternal stores.

The $Ca^{2+}-activated$ neutral protease calpain induced proteolysis has been suggested to play a role in certain cell growth regulatory proteins. Cyclin proteolysis is essential for cell cycle progression. D-type cyclins, which form an assembly with cyclin-dependent kinases (cdk4 and cdk6), are synthesized earlier in G1 of the cell cycle and seem to be induced in response to external signals that promote entry into the cell cycle. Here we show that cyclin D3 protein levels are regulated at the posttranscriptional level by calpain protease. Treatment of human breast carcinoma MDA-MB-231 cells with lovastatin and actinomycin D resulted in a loss of cyclin D3 protein that was completely reversible by the peptide aldehyde calpain inhibitor, LLnL. The specific inhibitor of the 26S proteasome, lactacystin, the lysosome inhibitors, ammonium chloride and chloroquine, and the serine protease inhibitor, phenylmethylsulfonylfluoride (PMSF), did not block the degradation of cyclin D3 by lovastatin and actinomycin D. Results of in vitro degradation of cyclin D3 by purified calpain showed that cyclin D3 protein is degraded in a $Ca^{2+}-dependent$ manner, and the half-life of cyclin D3 protein was dramatically increased in LLnL treated cells. These data suggested that cyclin D3 protein is regulated by the $Ca^{2+}-activated$ protease calpain.

In spite of adoption of various IMO Conventions over the past, the reason why large vessel accidents related to human life and marine environment occur is that the IMO Conventions are not effectively implemented due to contravention of the conventions by flag states. In particular, the implementation of the conventions are not well being performed because some flag states having weak genuine link between them and vessels haven't set up proper personal and structural organizations in charge of maritime safety and marine environment protection. From this background, IMO Resolution A.946(23) on the voluntary IMO Member-state Audit Scheme was adopted at the 23rd Assembly in Nov. 2003 and the Scheme is expected to be executed compulsorily in 2015 through the adoption of the IMO Resolution A.1018(26) in Nov. 2009. Accordingly, this study examined outline of the IMO Member-state Audit Scheme and the Code for the Implementation of Mandatory IMO Instruments used for the audit standards of this scheme. In addition, this study reviewed the member-states' obligations and responsibilities according to the compulsory implementation of the member-state audit scheme in 2015. Based on this, this study suggested the enhancement measures for maritime education and training of maritime education institutions of the Republic of Korea to cope positively with compulsory implementation of the IMO Member-state Audit Scheme.

How well citizens are represented by their representatives holds critical importance in representative democracy. While previous studies of ideological congruence have largely focused on Western established democracies, there was not as much attention paid to young democracies including, South Korea. This article investigates ideological congruence in South Korea based on multiple survey data sources collected from 2002 to 2016. When it comes to unidimensional Left-Right ideology, the distance between citizens and governments, unlike its citizen-assembly counterpart, has widened since 2000 sending a negative signal to the norm of representative democracy. As to multidimensional issue positions, however, it turns out that ideological congruence in South Korea has varied along issues such as aids to North Korea and Welfare spending. These results provide both citizens and parties with some important implications. For citizens, they are required to distinguish which party or candidate is more representative of the issue they value the most beyond a simple Left-Right line; for parties, they are required to deal with how to represent their supporters as well as today's increasing independents by strengthening their organizational capacity and providing effective party programs.

Recently, there has been an increase of accidents related to the rise in the use of Personal Mobility Vehicle (PMV). To solve this problem, the National Assembly announced an amendment that restricted the use of PMV to bicycle roads and to prohibited for people under 13 years old to use PMV, but there is no detailed information about travel speed and safety. In this study, a survey was conducted by dividing the group into minors and adults based on the age of obtaining a driver's license to find out the direction of improvement of laws and systems about PMV. Our results showed that adults considered PMV as more dangerous (Adults 5.50, Minors 4.94) and the suggested age for PMV use was lower from minors than adults (Adults 15.70, Minors 13.85). We found that proper travel speed on bicycle roads differed according to the presence of a driveway (Driveway 26.21 km/h, Non-Driveway 23.55 km/h) and minors had higher a travel speed than adults on all types of bicycle road. Also, Helmets for PMV were seen as the most important safety equipment on all types of bicycle road. and the importance of other safety equipment differed according to the presence of a driveway (Driveway Front-Lighting, Non-Driveway Car Horn). Through this study, It proposes that we have to make new regulations about the use of front lights and horns, as well as enforcement measures that differentiate the speed on each bicycle road type as a way to improve the laws and systems for PMV.

It recognizes the importance of mental health and well-being worldwide and consistently records public happiness figures through the World Happiness Report. COVID-19, which occurred in China in 2019, has changed people's daily lives a lot. The accumulation of stress caused by the prolonged epidemic is affecting people's happiness. The present research has revealed negative mental health effects such as "depression" and "anxiety" after the pandemic. In this regard, it was revealed that the happiness index was also lowered numerically. It is insufficient to analyze specific issues about changes in the issue of happiness felt by the public in Korean society after the epidemic. Therefore, this study aims to identify changes in the happiness issue of Koreans after COVID-19 and find ways to improve happiness. Data were collected from various aspects by searching 32 sub keywords based on ERG theory by dividing the period before and after COVID-19. The results of topic modeling before and after COVID-19 were classified into seven areas of happiness index 2.0 published by the National Assembly Future Research Institute and compared and analyzed. Based on the results of comparing the results of the before and after topic from the perspective of each area, a plan to improve happiness was presented. The academic implications of this paper are that the research on psychological changes caused by COVID-19 was expanded by mining the opinions of the actual public on 'happiness'. In addition, it has practical implications in that it specifically presented measures to promote happiness by utilizing the area of objective happiness indicators based on the existing research on ways to reduce happiness promotion unhappiness.

This study aims to provide basic data for revitalizing creativity research related to early childhood teachers by analyzing creativity research related to early childhood teachers. For this study, 103 master's and doctoral dissertations in Korea, which were searched through the National Assembly Library and the Research Information Sharing Service (RISS), were selected under the themes of 'early childhood teacher', 'creativity', and 'creativity research trends'. The frequency and percentage were calculated by analyzing creativity research related to early childhood teachers with five criteria: research period, research content, research method, research subject, and creativity factor. As a result of the study, first, as for the trends of creativity research related to early childhood teachers, 91 master's theses (88.3%) and 12 doctoral theses (11.7%) were conducted from 1991 to 2022, focusing on master's theses. Second, trends by research content were found in 20 basic studies (19.4%) and 83 practical studies (80.6%). Creativity research related to early childhood teachers is being actively conducted centering on practical research. Third, trends by research method showed 96 quantitative studies (93.2%), 7 qualitative studies (6.8%), and 0 literature studies (0%). Creativity studies related to early childhood teachers were being conducted with a focus on quantitative research. Fourth, the trend by research subject consisted of 100 studies (97.1%) related to early childhood teachers and 3 studies (2.9%) related to pre-service early childhood teachers. Fifth, trends by creativity factor were found in 56 studies (54.4%) related to teacher's variables and 47 studies (45.6%) related to creativity education methods. Studies related to teacher's variables were relatively higher than creativity education methods. As a result of this study, there is a lack of Christian education research in creativity research related to early childhood teachers, so it is expected that it will be done in the future.
