Maritime police recognize that the organizational culture of various acting as a member of the organization. Also, marine policing and security activities to determine the number of build. The overall culture of maritime police who share the organization sub-culture may take place. Maritime police organizational culture and a variety of types of group culture, hierarchical culture, development culture, rational culture examined the differences in perceptions. Maritime police aware of the general results of the analysis are as follows; First, the maritime police officers of the age group of 20 was the highest recognition in hierarchy culture and rational culture. Second, the maritime police officers of the rank of captain was the highest recognition in development culture and rational culture. Third, differences in the perception of organizational culture by recruitment analysis show the difference in cultural groups showed, in particular, the special recruitment group of police officers, and maritime police culture can be seen tend to appear low.
Purpose : This study was to examine the influence of job stress of 119 Emergency Medical Technician on fatigue and job satisfaction.

The National Library of Korea (Sejong), which was launched in December 2013, has been in the spotlight as a specialized library for Korean policy information and as a Sejong city complex cultural facility. Nevertheless, the essential identity, organizational status, division of affairs and core competencies, policy information collection, and services of the NLK (Sejong) are weak and inadequate. Therefore, this study developed a job model for establishing an essential identity and providing high-quality policy information services nationwide and suggested a strategic organizational reorganization plan. The job model was proposed as a total of 110 by adding 38 to the existing 72. Based on this job model, the short-term reorganization model (2023-2024) changed the grade of the library director from the current grade 4 (administrative officer) to Senior Executive, and the grade of the director by division from grade 5 (secretary) to grade 4. The sub-organization has expanded the current 3 divisions (planning management, policy information, and service use) to 4 divisions (planning administration, library collection and development, policy information service, and public service and culture, with a total of 51 personnel. In the mid-to-long-term model (2025-2032), the sub-organization was expanded to 4 divisions and 1 office (planning administration, library collection and development, policy information service, public service and culture, and policy information research), and presented a total of 61 personnel. To this end, it is necessary to persuade stakeholders with the argument of advocating the Korean policy information center, which is a macro-strategic goal, and focus all capabilities on strategic reorganization and revision of 「Decree on the Organization of the Ministry of Culture, Sports and Tourism」.
POLARBEAR is a ground-based experiment located in the Atacama desert of northern Chile. The experiment is designed to measure the Cosmic Microwave Background B-mode polarization at several arcminute resolution. The CMB B-mode polarization on degree angular scales is a unique signature of primordial gravitational waves from cosmic inflation and B-mode signal on sub-degree scales is induced by the gravitational lensing from large-scale structure. Science observations began in early 2012 with an array of 1.274 polarization sensitive antenna-couple Transition Edge Sensor (TES) bolometers at 150 GHz. We published the first CMB-only measurement of the B-mode polarization on sub-degree scales induced by gravitational lensing in December 2013 followed by the first measurement of the B-mode power spectrum on those scales in March 2014. In this proceedings, we review the physics of CMB B-modes and then describe the Polarbear experiment, observations, and recent results.
Objective: Agu pigs are indigenous to the Okinawa prefecture, which is the southernmost region of Japan. Agu pigs were exposed to a genetic bottleneck during the 20th century, due to the introduction of European pig breeds. The objective of this study was to elucidate the genetic structure of Agu pigs and to determine their relationships with those of five European breeds, two Chinese breeds and Ryukyu wild boar using microsatellite markers. Methods: A total of 203 DNA samples from 8 pig breeds were used in this study. Genotyping was performed using 21 microsatellite markers distributed across 17 chromosomes. Results: Numbers of effective alleles in Agu pigs were fewer than in European breeds and Ryukyu wild boar. Among domestic pigs, Agu pigs had the lowest heterozygosity (0.423) and highest inbreeding coefficient (FIS = 0.202), indicating a severe loss of heterozygosity in Agu pigs possibly due to inbreeding. Neighbor-joining tree analysis was performed based on Reynolds' genetic distances, which clustered Agu pigs with Duroc pigs. However, principal component analysis revealed a unique genetic position of the Agu pig, and the second principal component separated Agu pigs from all other breeds. Structure analysis with the optimal assumption of seven groups (K = 7) indicated that Agu pigs form an independent cluster from the other breeds. In addition, high and significant FST values (0.235 to 0.413) were identified between Agu pigs and the other breeds. Conclusion: This study revealed a substantial loss of genetic diversity among Agu pigs due to inbreeding. Our data also suggest that Agu pigs have a distinctive genetic structure, although gene flows from European breeds were observed.
The purpose of this study is to propose an effective leadership in the hospital management by analyzing the relationship of the effect of the specialty hospital CEO's leadership on the employees' organizational effectiveness as well as the customer orientation, and the mediation effects of the organizational effectiveness on the relation between hospital CEO's leadership and the customer orientation. The questionnaires of the survey targeting the 99 specialty hospitals were collected that 786 copies of them were utilized in analysis. The major outcomes of the research can be summarized as follows. Firstly, transformational leadership of specialty hospital CEO generally has the greater impact on the employees' job satisfaction, organizational commitment and turnover intention than his transactional leadership. Secondly, the most important sub-variable of specialty hospital CEO leadership affecting the organizational effectiveness of the employees are charisma of transformational leadership and contingent reward of transactional leadership. Thirdly, the sub-variable of specialty hospital CEO leadership which has the greatest impact on customer orientation of employees is the active management-by-exception of transactional leadership. Fourthly, the sub-variables in the organizational effectiveness such as job satisfaction, organizational commitment and the turnover intention of hospital employees play mostly the partial mediation role between the customer orientation of employees and the leadership of a specialty hospital CEO. This means that the more the organizational effectiveness of specialty hospital employees improves, the more the customer orientation does. Thus, specialty hospital CEOs need to pay attention to the sub-variables in organizational effectiveness so as to improve the customer orientation of the employees. To explore further the nature of the effect of hospital leadership in the future, apart form the variables of the organization effectiveness used in this study to improve the customer orientation of employees through the leadership of the specialty hospital CEO, the research to identify other factors which have greater influence and explanatory power will be needed.
With increasing of GDP, the registration number of passenger cars has exceeded 20 million last year in Korea. Especially, the registration number of the diesel engine vehicles has been increasing. However, the WHO(World Health Organization) IARC (International Agency for Research on Cancer) has reported that diesel engine exhaust gas is an one of HAPs, which has carcinogenic for human, and they have designated it to Group 1. To solve this problem, exhaust gas from diesel engines has to be controlled. Thus, it has been controlling by European regulatory standard in Korea. On the other hand, in order to meet the enhanced emission regulations, all manufacturing company applied $NO_x$ control device to vehicles such as EGR (Exhaust Gas Recirculation), SCR (Selective Catalytic Reduction) and so on. However, these devices (EGR, SCR) were operated by difference reaction mechanism respectively, and the composition of exhaust gas would be differenced from that of them. In this study, it was conducted to evaluate variety characteristics on changing of exhaust gas composition by each $NO_x$ control device, and the heavy duty diesel trucks were chosen as experimental vehicles. From the result, it revealed that vehicles (with EGR) were discharged higher THC as 52.5% than that of others (with SCR). However, it did not followed that trend, in the case of CO; it was discharged as 57.2% lower than that of others (with SCR). In the future, these data would be used to apply to efficient $NO_x$ control device for meeting to EURO 6.
This study aims to introduce the structure of the impact-based heat health warning system on 165 counties in South Korea developed by the National Institute of Meteorological Sciences. This system was developed using the daily maximum perceived temperature (PTmax), which is a human physiology-based thermal comfort index, and the Local ENSemble prediction system for the probability forecasts. Also, A risk matrix proposed by the World Meteorological Organization was employed for the impact-based forecasts of this system. The threshold value of the risk matrix was separately set depending on regions. In this system, the risk level was issued as four levels (GREEN, YELLOW, ORANGE, RED) for first, second, and third forecast lead-day (LD1, LD2, and LD3). The daily risk level issued by the system was evaluated using emergency heat-related patients obtained at six cities, including Seoul, Incheon, Daejeon, Gwangju, Daegu, and Busan, for LD1 to LD3. The high-risks level occurred more consistently in the shorter lead time (LD3 → LD1) and the performance (rs) was increased from 0.42 (LD3) to 0.45 (LD1) in all cities. Especially, it showed good performance (rs = 0.51) in July and August, when heat stress is highest in South Korea. From an impact-based forecasting perspective, PTmax is one of the most suitable temperature indicators for issuing the health risk warnings by heat in South Korea.
This study assessed the relationships between levels of $PM_{10}$ and hospitalization rates for asthma among children from 2003 to 2005 at four major cities in Korea. In addition, we estimated the reduced number of asthma hospitalization associated with an ambient $PM_{10}$ improvement to the acceptable levels as recommended by the World Health Organization (WHO). The Generalized Additive Model (GAM) was used to estimate the relative risks (RR) of asthma hospitalization associated with changes in $PM_{10}$ The RRs of children's asthma hospitalization for every $10{\mu}g/m^3$ increment in $PM_{10}$ were 1.009(95% CI = 1.004-1.014) in Seoul, 1.013(95% CI = 1.006-1.021) in Incheon, 1.009(95% CI = 1.002-1.016) in Busan, and 1.021(95% CI = 1.005-1.037) in Ulsan. We assessed $PM_{10}$ related health benefits from implementing the WHO's guidelines (24-hour average $50{\mu}g/m^3$) using the U.S. Environmental Protection Agency's Environmental Benefits Mapping and Analysis Program. The estimated benefits were 439(95% CI = 216-666) reduced asthma hospitalization in Seoul, 720(95% CI = 304-1,151) in Incheon, 260(95% CI = 66-459) in Busan, and 126(95% CI = 30-228) in Ulsan. It was concluded that improving $PM_{10}$ condition to the WHO guideline would make a significant contribution to the reduction in asthma hospitalization among children. Therefore, public health measures are still needed to improve air quality in Korea.

A number of Korean Chicken breeds were registered in Domestic Animal Diversity Information System (DAD-IS, http://dad.fao.org/) of the Food and Agriculture Organization (FAO). Evaluation of genetic diversity and relationship of local breeds is an important factor towards the identification of unique and valuable genetic resources. Therefore, this study aimed to analysis the genetic diversity and relationship of 22 Korean Chicken breeds using 12 microsatellite (MS) markers. The mean number of alleles for each variety was 5.52, ranging from a 3.75 (Leghorn F; NF) to a 7.0 (Ross). The most diverse breed was the Hanhyup3 (HCC), which had the highest expected heterozygosity (HExp) (0.754) and polymorphic information content (PIC) (0.711). The NF was the least diverse population, having the lowest HExp (0.467) and PIC (0.413). As a result of the principal coordinates analysis (PCoA) and factorial correspondence analysis (FCA) confirmed that Hy-line Brown (HL) and Lohmann Brown (LO) are very close to each other and that Leghorn and Rhode Island Red (RIR) are clearly distinguished from other groups. Thus, the reliability and power of identification using 12 types of MS markers were improved, and the genetic diversity and probability of individual discrimination were confirmed through statistical analysis. This study is expected to be used as basic data for the identification of Korean chicken breeds, and our results indicated that these multiplex PCR marker sets will have considerable applications in population genetic structure analysis.
