This research is a case study about the personnel management policy of Bachae co., Ltd. Bachae Co., Ltd. suggests as a successful model that by implementing the pro-active personnel management strategy eliminated the seniority, age-limit, academic snobbism, the qualities critical for managerial success are leadership, motivation, decisiveness, flexibility. It gives a solution especially to medium-sized companies suffering the manpower shortage, that the adequate motivation through strong leadership to employee results in not only job satisfaction but also organization absorption. The fact that company care about even the failure staying at their jobs longer without hurting their self pride to be loyal employee is a very demonstrative and great method which motivates middle & midium size of companies how to manage and utilize the human resources.

Southern blot analysis revealed a ubiquitous distribution and high copy number of Ty3-gypsy-like elements in the genome of Hibiscus syriacus. Comparative phylogenetic analysis of the large subunit of Rubisco and the integrase region of Ty3-gypsy elements in various plant species indicated that the retrotransposon-like sequences have different evolutionary histories and their own unique polymorphism in the H. syriacus population. Sequence-tagged site-restriction fragment length polymorphisms (STS-RFLP) analysis also indicated great variability in the numbers and sequences of Ty3-gypsy-like elements within H. syriacus varieties. Ty3-gypsy-like elements may still be active within H. syriacus, since Northern analysis of wounded leaves of H. syriacus variety Saehan with a probe for the integrase domain gave strong hybridization signals. The sequence heterogeneity and ubiquity of the Ty3-gypsy-like elements in H. syriacus genomes could provide reliable DNA markers for line identification as well for the analysis of genetic diversity in H. syriacus.

정보통신기술의 발달로 말미암아 병의원에서도 다양한 정보시스템의 도입이 활발하고, 초기에는 데이터의 전자적 관리 및 공유를 위한 시스템이 주를 이루었으나 점차 병의원 운영관리에 대한 직접적인 의사결정지원 기능이 강조되고 있다. 그러나 기존의 시스템들은 대부분 의료 전문가들의 지식에 기반하여 진료행위가 정해진 절차를 벗어나지 않도록 하는 데에만 초점을 맞추었고, 환자나 경영자 입장을 충분히 고려하지 못하였다. 이에 본 논문에서는 전문적 의료 지식 베이스가 아닌 병의원에서 수집된 데이터를 기반으로 다양한 참여자들에게 유용한 기능을 제공하기 위한 능동형 임상의사결정지원시스템의 개념과 구조에 대하여 논의하고자 한다.

A PVA-soft hydrogel, which is a semi-solid form in container, whereas after applying on the skin, it formed a thin layer within a few minutes. In this study, we prepared a novel type PVA-soft hydrogel containing 6-methyluracil as active drug, and the therapeutic value was characterized. To evaluate the therapeutic value of the PVA-soft hydrogel containing drug, various animal models, thermal burn model, incision & excision wound rat model were used. We also measured the wound size and breaking strength to calculate the wound healing extent after single or multiple administration. The wound size of soft hydrogel treated group decreased rapidly than that of control group after multiple dosing in excision wound model. And, the breaking strength of the soft hydrogel treated group was greater than that of control group in incision wound model.

On this research, recognizing that ship inspection is closely related in improving ship safety', the importance of active quality managements of ship inspection has been notified. This paper aims to explore effective ways to improve inspection service and develop customer-centered inspection administration, by carrying out a case study on K Company. The methods applied for this research project are as follows, 1) sector-based examination of the existence of the ISO 9001 system; 2) evaluation of the operation of the system; 3) conduction of a survey questionnaire with the participation of all staff and inspection companies to analyze customer satisfaction of their inspection service, and 4) statistical analysis of the data collected from the survey questionnaire.

A butyrolactone ester of cefazolin (CFZ-BTL) was synthesized by the esterification of cefazolin (CFZ) with $\alpha$-bromo-${\gamma}$-butyrolactone. The synthesis was confirmed by the spectroscopic analysis. The CFZ-BTL was more lipophilic than the CFZ when assessed by n-octanol/water partition coefficients at various pH. The CFZ-BTL itself did not show any antimicrobial activity in vitro, but after oral administration of CFZ-BTL to rabbits, exerted significant anti-microbial activity in serum samples when measured by the inhibion zone method in nutrient agar plates, due to conversion of CFZ-BTL to an active metabolite, probably CFZ, in the body. The CFZ-BTL was also converted into CFZ as confirmed by in vitro incubation study, with tissue homogenates (liver, blood and intestine) of rabbits. The liver showed the fastest conversion rate, probably via the hydrolysis mechanism. In vivo metabolism of CFZ-BTL to CFZ was also confirmed in vivo serum samples by HPLC. The oral bioavailability of CFZ-BTL in rabbits was 1.6-fold increased when compared to CFZ, resulting from followed by enhanced lipophilicity increased passive absorption in the intestine.

Purposes: The purposes of this study is analysis of business performance in national university hospitals in Korea. Methodology: Data from 2010 to 2019 were collected from balance sheet, income statement, and annual reports in 11 national university hospitals. The dependant variables are business performance which are operating margin to total assets, operating margin to gross revenue, and net income to gross revenue. The independent variables are the number of bed, hospital location, opening, liquidity, stability, and activity. Findings: In recent years, activity has been shown to have a lot of influence on management performance. National university hospitals increase profitability by using resources as efficiently as possible. The short-term debt and fixed assets have been increased rapidly in recent years. It was found that management performance has been increased through active investment using financial leverage. Practical Implications: Based on these results, this study will be the basic data for efficient management of national university hospitals.

Commercial products with antibiotics like streptomycin as active ingredients have been used to control soft rot disease caused by Pectobacterium species for a long time. In this study, antibiotic resistance of twenty-seven Korean strains of Pectobacterium species including P. carotovorum, P. odoriferum, P. brasiliense, and P. parmenteri, which were previously shown to be susceptible to the bacteriophage phiPccP-1 was surveyed using a disk diffusion assay. While all strains were highly susceptible to ampicillin, kanamycin, chloramphenicol, tetracycline, and rifampicin, some strains showed weak susceptibility to 300 ㎍/ml of streptomycin. Furthermore, some of them are partially or completely resistant to commercial pesticides-Buramycinand streptomycin at the concentration of 250 ㎍/ml that is recommended by the manufacturer for streptomycin-based pesticides. These results indicate the presence of streptomycin-resistant Pectobacterium strains in South Korea, and the development of antibiotic alternatives to control soft rot is needed.

Platycodon grandiflorum and Glycyrrhiza uralensis contain several bioactive compounds, such as saponin, oleanolic acid, and flavone. P. grandiflorum and G. uralensis have traditionally been used to treat disorders related to blood pressure, diabetes, and counteracting poison, and they have antinociceptive and antiinflammatory properties. However, the validity of complex saponin's vasodilatory effect has not been scientifically investigated. Therefore, this study explores the vasodilatory effect of complex saponin extracted from P. grandiflorum and G. uralensis mixture extract on rabbit carotid arteries. To this end, arterial rings with intact or damaged endothelium were used in an organ bath experiment and contracted by endothelin. Complex saponins, the major active constituents of P. grandiflorum and G. uralensis mixture extract, exhibited a moderate vasodilatory effect on the rabbit's basilar arteries. Therefore, treatment with complex saponin extracted from P. grandiflorum and G. uralensis mixture extract may selectively accelerate cerebral blood flow through basilar arterial dilation. Overall, the findings suggest that the extracted complex saponins can serve as vasodilator sources.

This study is to find out how Korean teenagers think about mobile payment system. In the case of mobile payment using such a smartphone, a simple payment service is currently being implemented in Korea through deregulation of Active X and public certificates at the government level to provide users with more convenient financial services. This study conducted a pilot test to find out what they think about mobile payment service for high school students in Busan. As a result, Korean teenagers, especially high school students, responded very positively to the mobile payment service.
