Domestic industry has a long history, but it has been suffering for a long time due to its poor competitiveness in management ability, supply of materials, technological development, sales marketing, and distribution networks. Moreover, the industry has not established its strong presence in the world market but is exposed to increasingly greater agonies because of inactive domestic demands, increase rate of import versus export, diversified government policies, and non-selective introduction of high-quality and low-priced foreign named brands of ceramics into the country. Theses factors have partly contributed to consumers' low or negative recognition.

Curved intakes are commonly used from commercial aircraft to military missile. Sound radiation from the intake of air vehicle affects cabin noise, community noise and military detection. In this paper, Sound radiation from curved intake is computed using the high order, high resolution scheme. The generalized characteristic boundary conditions, adaptive nonlinear artificial dissipation model and conformal mapping for high order, high resolution scheme are used. The geometric change of curved intake and the frequency of acoustic source are considered. Two dimensional Euler equations are solved for theses analyses.

Most small and petty marine engine mechanical shops are jumbled up and their facilities are falling behind, and is varying. By theses reasons, it's capacity becomes weak and also by the insufficience of the promotion policy, it is hard to be expected to improve their business. The feature, management, manpower, facilities for the marine engine mechanical shops were researched and their problems were analyzed. In this study, the way to strengthen their capacity and to manage the shops efficiently was researched.

We research hardware and software for measurement of most suitable condition of the plant growth. that is put of the future oriented that plant growing system. The environment cannot offer the most suitable condition of the plant growth. so we are approached most suitable condition of the plant growth by adjustment of artificial condition of the plant growth but in theses experiment includes some fault that is subjectivity of observation. therefor we develop vision equipment and software for objective observation measurement.

This paper reports on a study investigating key attributes of service recovery strategies in internet shopping mall. In theses day, service recovery has received important attention in the service operation management literature. Service recovery involves those actions designed to resolve problems, alter negative attitudes of dissatisfied consumers and to ultimately retain these customers. The study examined that service recovery strategies (apology, compensation) impact on the customer satisfaction. And customer satisfaction impacts on customer loyalty with SEM (Structural Equation Modeling). This study can be used a strategic implication for internet shopping mall managers to develop successful service recovery strategies.

A new series of phosphonate side chain analogues of 1$\alpha$,25-dihydroxyvitamin $D_3$ (1) have been synthesized. Antiproliferative activities of theses analogues (8a,b and 9a,b) using human keratinocyte cell shows that analogues which have natural A-ring show higher activity than unnatural A-ring series and almost equally active to 1 $\alpha$,25-Dihydroxyvitamin $D_3$(1) at 1 $\mu$M level.

We have previously reported three new oleanene-type glycosides and kudzusaponin $A_3$ methyl ester and subproside II methyl ester from the roots of Echinosophora koreensis. Further study has now led to the isolation of three known oleanen-type glycosides. sophoraflavoside I, azukisaponin V, and kudzusaponin $SA_3$ as their methyl esters. The structures of theses compounds were characterized by spectroscopic and chemical methods.

In 2014, Liu and Wang established a large number of interesting reduction, transformation and summation formulas for the Kampé de Fériet function. Inspired by the work, we aim to find further several transformation and reduction formulas for the Kampé de Fériet function. Theses formulas are mainly based on the formulas given by Liu and Wang [33].

This study purports to contribute in deepening our understanding of ISD (instructional systems design/development) from Edward Hall's concept of intercultural communication. Renowned anthropologist Edward Hall introduced three concepts of cultural differences: time, space, and context. This paper explores how theses cultural dimensions - time, space and context- are reflected in ISD and compares the cultural differences between the east and the west that emerge in the process of applying ISD.

Purpose: The authors reviewed researches related to performance appraisal(32 researches), in order to identify the direction for future research and to establish a credible performance appraisal system. Method: Almost all of the theses and research published in 9 major journals of nursing in korea were reviewed. Results: Most of research(84.4%) were theses and all researches were used to non-experimental design; survey 81.3%, methodological research 15.6%, review 3.1%. The major subjects of study were appraisees and appraisers. Psychosocial data collection which only used questionnaire were 81.3% and carried out interview(12.5%) and delphi-method(3.1%). Data analysis methods were used frequency 78.1%, t-test 62.5%, mean/SD 59.4%, Pearson's correlation 50%, and Cronbach α 50%. Appraisal tool used or developed in studies was graphic rating scales in nine studies and ran parallel with forced distribution in 2. Also, MBO and BSC were developed. Total number of korean terms in performance measurement were 11, and english terms 15. The tendency of the terms was toward performance appraisal or evaluation. Conclusion: In the light of results, we expect development of corporate appraisal tool that can evaluate nurse competence and performance. Total performance management system also should be established.
