Wire harness is a component for efficient control when electronic parts are required such as construction machinery and electric vehicles. With emerging issues such as autonomous driving and automation in construction, a wire harness composed of multiple cables has become an essential part because more electronic parts are required. However, when a wire harness failure occurs, systems can be stopped, accidents can occur, and economic damage can be significant. Therefore, in this paper, we developed a digital fault screening system that could easily and quickly diagnose faults in the wire harness. The principle of the developed system was to sequentially send pulse signals to the wire harness and use returned signals to perform fault detection. As a result of diagnosing faults using the developed failure detection system, a detection accuracy of 99.9 % was confirmed through the experiments.

Nail service business should adapt itself to the change of service environment of the nail art trend andtechnique, which needs to examine the relation of the chief manager, employee and customer, so thebusiness strategy of nail salon could be formed by establishing detailed planning strategy and performancemeasurement index. For the management of nail salon, the performance measurement index that canassess the financial performance, customer satisfaction measurement , technical and educationalstandard, etc. should be developed to evaluate the intangible performance like service and satisfactionlevel in addition to the typical performance. Currently, the study on the Key Performance Indicator (KPI)for improving the performance of nail salon management is insufficient at the site of beauty business aswell as in the academic world. In this study, the evaluation index for nail salon management to enhancethe competitiveness and value of beauty treatment industry was developed by reflecting the reality of nailbusiness. So, KPI of nail salon management was drawn by 3 round-delphi with BSC (Balanced ScoredCard) as follows. First, in the finance perspective ‘personnel expenses’, ‘cost ratio’, ‘operating profit ratio’,‘total sales’, ‘sales growth rate’and ‘total capital investment efficiency’ were adopted. Second, in thecustomer perspective ‘service improvement’, ‘new customers secure’, ‘service quality’, ‘service speed’,‘customers DB’, ‘regular customers keeping rate’ and ‘customer satisfaction rate’ were adopted. Third, inthe inter process perspective ‘business manual application’, ‘membership price grade’, ‘brand image’, ‘staffproductivity ratio’, ‘manual maintenance’ and ‘product & service development’ were adopted. Finally, thelearning and growth perspective ‘staff satisfaction’, ‘staff development’, ‘educational level and rotation time’,‘appropriate reward system’, ‘benefits level’ and ‘vision share’ were adopted.
중국인일본어학습자의 조건표현 습득 연구 : 「と·ば·たら·なら」를 중심으로
김선영 일본어문학회 2012 일본어문학 Vol.57 No.-
中国人学習者を対象としてアンケート調査を行い、日本語の条件表現「と·ば·たら·なら」の使用様相を考察した。さらに、韓国人学習者と日本語母語話者との使用様相を対照分析して中国人学習者の条件表現の習得過程を考察した。その結果、中国人学習者における条件表現は初·中級レベルにはあまり習得が進まないが、中·高級レベルになると徐々に習得が進むことがわかった。なお、4形式の正答率を見ると、「と」が一番高い正答率を示し、韓国人学習者だけでなく、他の母語話者を対象とした先行研究の結果を支持して「と」は母語に関係なく習得しやすい項目だと言える。なお、中国人学習者は条件表現の習得時、母語の正·負の影響を受けている。つまり、予定用法「たら」は正の影響、確定の非過去用法「と」と「なら」は負の影響を受けているだろう。日本語母語話者の使用様相と比較した結果、日本語母語話者は一つの意味用法に様々な形式を用いているが、中国人学習者は一つの意味用法に一つの形式を用いる傾向が見られた。

디지타이저를 이용하여 도표로 발표된 물성 데이터들을 정밀하고 신속하게 수치데이터로 환산할 수 있는 알고리듬을 제안하였다. 수치자료화한 데이터를 이용하여 필요한 내삽이나 공정해석에 응용할 수 있는 가시적인 최적화방법에 대하여 검토하였다. Pitzer의 압축인자 도표를 수치화한 후 내삽한 데이터와 이를 원래의 수치데이터 값들과 비교한 결과 도표자료 내삽의 신뢰도를 확인할 수 있었다. 또한 CO₂에 의해 식용대두유를 추출하는 초임계 용매 추출공정에 응용한 결과 용해도 및 용매의 물성도표만으로 분리수율을 증가시키면서 조업에너지 소요량을 최소화할 수 있는 열역학적 최적화 방안을 제안하였다. We presented an algorithm that can constructs digitized databases from various graphical representations such as thermodynamic property charts by utilizing a desk-top digitizer properly. It is found that any types of usual model-oriented process calculation such as interpolations and process optimization can be equivalently accomplished with these digitized property charts. As the first illustration, the compressibility factors for any reduced temperature and pressure can be evaluated quickly and accurately by digitized Pitzer's Z-chart with linear and cubic spline interpolation methods. As the second illustration, optimum operation paths which give maximum separation yield with the least of energy demand can be sought with the digitized property chart for the supercritical extraction process of soybean oil with carbon dioxide.

Objectives : This study aimed to investigate the prospective associations of premenstrual dysphoric disorder (PMDD) with quality of life, socio-occupational function and disability. Methods : 170 nurses were recruited 6om two general hospitals. Interviews were made at baseline and at four follow-up points (two mid follicular phases and two late luteal phases ofthe two consecutive menstrual cycles). The baseline evaluation Consis-ted of sociodemographic characteristics and menstmal history. PMDD was diagnosed by DSM-IV criteria after observation of the two menstrual cycles. The follow-up evaluations were consisted ofthe World Health Organization Quality of Life-Brief form, the Social and Occupational Functioning Assessment Scale, and the World Health Organization Disability Assessment Scale-II. Results : PMDD was detected 15 (8.8%) of 170 participants. The PMDD group showed significantly worse quality of life and socio-occupational functioning than the none-PMDD group particularly at the late luteal phases. No significant differences were found in sociodemographic characteristics and menstrual history between those with and without PMDD. Conclusion : PMDD was prospectively associated with worse quality of life and socio-occupational functioning in this study group.

We explored the transporting processes for the Asian dust observed over South Korea. The frequency of Asian dust days (ADDs) were used to analyze the associations of the ADDs with land surface conditions over the four source regions, including inner-Mongolia, the Gobi Desert, Manchuria, and Loess Plateau, and atmospheric synoptic variables over central and eastern Asia. Precipitation and Palmer Drought Severity Index (PDSI) in the source regions during the previous summer were negatively correlated with the ADDs in South Korea. Statistically and physically more significant processes were found in the associations of atmospheric synoptic conditions with the ADDs. The intensified winds of northwesterly-northerlynorthwesterly over a pathway of the Asian dust from the source regions to South Korea were identified during high ADDs years in South Korea. A dipole pattern of anti-cyclonic and cyclonic anomalies over central and eastern Asia, respectively, supported the Asian dust pathway.

Background Amid growing demand for sustainability across society, resale is attracting attention as an alternative to realizing the fashion circulation. The purpose of the study is to classify the type after looking into resale project case in luxury fashion and find out imbedded significance. Methods In the research method, First, concept of resale and its spread background were reviewed. Second, focusing on the cases from 2017 to 2022, when the resale of luxury fashion was developed, the types were classified and the contents were identified. Third, the significances were derived by synthesizing the contents of the study. Result Resale project of luxury fashion breaks into three: partnership contract with resale platform, process of dependent resale program, and takeover or share acquisition of resale platform. Meaningful point exists in that, in spite of some difference in specific content and type, this trend gives luxury fashion the newly changed implication, luxury fashion is sustainable business model, and that fashion boundary becomes widened according to progress in product certification technology. Conclusion This study would help to comprehend the luxury fashion’s resale trend and the change in fashion recycle paradigm for sustainability. It is expected to realize the differentiated resale service and extension to overall luxury fashion industry. 연구배경 사회 전반에서 지속가능성에 대한 요구가 커지는 가운데 리세일은 패션 순환을 실현할 수 있는 하나의 대안으로 주목받고 있다. 본 연구는 럭셔리 패션의 리세일 프로젝트 사례를 고찰하여 유형을 분류하고, 그 의의를 조명하는 것이다. 연구방법 첫째, 리세일 개념과 확산 배경을 문헌 고찰하였다. 둘째, 럭셔리 패션의 리세일이 전개된 2017년부터 2022년까지의 사례를 중심으로 유형을 분류하고, 내용을 파악하였다. 셋째, 고찰한 내용을 종합하여 의의를 도출하였다. 연구결과 럭셔리 패션의 리세일 프로젝트는 리세일 플랫폼과 파트너십 체결, 독자적인 리세일 프로그램 진행, 리세일 플랫폼 인수나 지분 확보의 세 가지 유형으로 구분되었다. 구체적인 내용과 방식에는 차이를 보이나 이러한 동향은 럭셔리 패션의 의미를 변화시키고, 럭셔리 패션이 지속될 수 있는 비즈니스 모델이라는 점, 그리고 제품 인증 관련 기술 분야의 발전에 따른 새로운 패션 영역 확장이라는 측면에서 의의를 지닌다. 결론 본 연구를 통해 럭셔리 패션의 리세일 동향과 지속가능성을 위한 패션 순환 패러다임의 변화를 파악할 수 있었다. 앞으로 차별화된 리세일 서비스와 럭셔리 패션업계 전반으로의 확대를 기대한다.
