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.

A Set of Theoretical Norms for Sacramental Education

김선영 한국기독교교육학회 2019 기독교교육논총 Vol.0 No.57

The two marks of the true church is the Word and the sacraments. Every Christian knows that the Word is all-important. Although there is a question whether the Word is properly interpreted and proclaimed, preaching is the center of the Protestant worship service; preaching skill is the most important qualification as a popular pastor. Sermons and Bible studies are available everywhere in South Korea. Most Protestant Christians, however, in South Korea are not aware of the significance of the sacraments. There is, in particular, a high possibility that a good few Christians never get an opportunity to participate in communion all the year round. A more serious problem is that these Christians do not feel the need to participate, most likely because they are not well informed of its significance. Being conscious of the current situation of the Protestant churches in South Korea in terms of the sacraments, this paper is going to argue that more attention must be paid to the sacraments as one of the marks of the true church and that an indispensable part of such an effort is to further develop education for the sacraments or sacramental education. There are a variety of approaches and ways for further development, and the goal of this paper is to establish a set of theoretical norms for sacramental education.

‘그리고’류의 문법범주의 판별에 대하여

김선영 형태론 2004 형태론 Vol.6 No.2

Kim, Sun-young, 2004. On the Syntactic category on ‘kuliko’ etc. Morphology 6.2, 355-366. There are two alternative views concerning the syntactic category of sentence-initial ‘kuliko, kulena’, etc. One view considers these as pro-verbs or verbal substitutes, while the other defines them as conjunctive sentential adverbs. The latter view is justified by the fact these adverbs have the function of connecting sentences, and follows the categorization of conjunctive adverb in traditional school grammar. In origin, they are derived from pro-verbs or verbal substitutes through a process of lexicalization whereby the verbal substitutive function is lost. But it is not safe to assume all such pro-verbs or verbal substitutes have undergone the lexicalization process; it is also possible that some of them have not yet developed into adverbs. Thus, the classification of these sentence-initial adverbials is related to the question of how to distinguish derived adverbials from pro-verbs. In order to facilitate this classication, this article observes the function and meaning of the verbal substitutes and connective endings and concludes that their function and meaning can be explained with reference to the functions and features of verbal substitutes, and considers whether these sentence-initial adverbials are freely replaceable by connective endings.(Seoul National Unversity) 문장의 첫머리에 쓰인 ‘그리고’류의 문법범주에 대해 두 가지 가능성이 존재하는데 대용용언과 접속부사이다. 전통적으로 ‘그리고, 그러나’ 등이 문장의 맨 앞에 쓰여 후행문장을 선행문장과 이어주는 기능을 한다고 보고 이를 ‘접속부사’라 불렀다. 이는 대용용언의 부사형에서 대용의 통사적 기능을 상실하고 형성된 것이다. 그러나 이들 모두를 접속부사로 어휘화된 형태로 처리하는 데는 문제가 있다. 공시적으로 접속부사로 어휘화된 형태와 어휘화되지 않은 형태가 존재할 가능성이 있기 때문이다. 따라서 문장의 첫머리에 쓰인 ‘그리고’, ‘그러나’ 등의 문법범주를 판별하는 문제는 접속부사로 어휘화된 형태와 대용용언의 부사형을 구별하는 문제와 관련한다고 할 수 있다. 이 글에서는 문장의 첫머리에 쓰인 ‘그리고’류의 문법범주를 판별하기 위해 대용용언의 기능과 특징을 검토한 후 이들의 쓰임이 대용용언의 기능과 특징으로 모두 설명가능한가에 대해 고찰하고 이들이 연결어미와 서로 자유롭게 대치되어 쓰일 수 있는지 살펴보았다.

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.

김선영,김은주,이인복 大韓齒科保存學會 2010 Restorative Dentistry & Endodontics Vol.35 No.5

Objectives: The aim of this study was to examine changes in the dentinal fluid flow (DFF) during desensitizing agent application and to compare permeability after application among the agents. Materials and Methods: A Class 5 cavity was prepared to exposure cervical dentin on an extracted human premolar which was connected to a sub-nanoliter fluid flow measuring device (NFMD) under 20 cm water pressure. DFF was measured from before application of desensitizing agent (Seal&Protect, SP; SuperSeal, SS; BisBlock, BB; Gluma desensitizer, GL; Bi-Fluoride 12, BF) through application procedure to 5 min after application. Results: DFF rate after each desensitizing agent application was significantly reduced when compared to initial DFF rate before application (p < 0.05). SP showed a greater reduction in DFF rate than GL and BF did (p < 0.05). SS and BB showed a greater reduction in DFF rate than BF did (p < 0.05). Conclusions: Characteristic DFF aspect of each desensitizing agent was shown in NFMD during the application procedure. 연구목적: 본 연구의 목적은 미세 유체 흐름 측정장치를 이용해서 각 상아질 지각과민 처치제의 적용 과정 중 발생하는 상아 세관액 흐름의 유동을 관찰하고, 상아질 지각과민 처치제 간 적용 후 투과도 감소의 차이를 비교하고자 하는 것이다. 연구 재료 및 방법: CEJ 5 mm 하방에서 절단한 소구치를 미세 흐름 측정장치에 연결하여 20 cm H₂O의 정수압을 가하였다. 치경부에 상하 3 mm, 근원심 4 mm, 깊이 2 mm의 V자 형태의 5급 와동을 형성하고 smear layer를 제거하기 위해 15초 동안 산 부식한 후 상아질 지각과민 처치제를 적용하였다. 사용된 상아질 지각과민 처치제는 Seal&Protect (SP), SuperSeal (SS), BisBlock (BB), Gluma desensitizer (GL), Bifluoride 12 (BF) 이다. 상아세관액의 흐름은 지각과민 처치제 도포 전부터 도포 후 5분까지 실시간으로 측정되었다. 결과: 실험에 사용한 모든 상아질 지각과민 처치제는 적용 후의 상아세관액 흐름율이 적용 전에 비해 유의하게 감소하였다(p < 0.05). SP는 GL과 BF에 비해 유의하게 투과도 감소가 나타났다 (p < 0.05). SS와 BB는 BF에 비해 유의하게 투과도 감소를 보였다 (p < 0.05). 결론: 지각과민 처치제의 도포 과정 동안 각 처치제의 특징적인 상아세관액의 유동을 미세 유체 흐름 측정장치를 통해 관찰 할 수 있었다.

김선영,조병훈,백승호,임범순,이인복 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.6

본 연구의 목적은 아말감과 복합레진의 수복 과정과 수복 후 상아세관액의 흐름(dentinal fluid flow, DFF)을 측정하기 위함이다. 치근을 절제한 제 3 대구치를 자체 제작한 미세 유체 흐름 측정장치에 연결한 후 1급 와동을 형성하여 아말감과 복합레진 수복을 시행하였다. DFF의 측정은 와동 형성부터 수복 후 30분까지 연속적으로 이루어졌고, 수복 후 3, 7일에 재 측정하였다. 주수 하에 와동 형성 시 DFF는 inward로, 끝난 후에는 outward로 바뀌었다. 아말감 충전 시 DFF는 inward로 바뀌었고 충전 완료 후 미약한 outward DFF를 보였다. 복합레진 수복의 경우, 산 처리 후 수세와 건조 시 각각 inward와 outward DFF를 보였고 primer도포 후 공기 분사는 급격한 outward, 소수성 본딩제를 적용하는 단계에서는 outward 였던 DFF가 감소하여 0에 가까워지거나 약간 inward 흐름을 보였다. 접착제와 복합레진의 광중합은 급격한 inward의 DFF를 일으켰다. 수복 후 30분, 3일, 7일째 수복 재료에 따른 DFF의 감소에 통계적으로 유의한 차이는 없었다 (p>0.05). The aim of this study was to measure the dentinal tubular fluid flow (DFF) during and after amalgam and composite restorations. A newly designed fluid flow measurement instrument was made. A third molar cut at 3 mm apical from the CEJ was connected to the flow measuring device under a hydrostatic pressure of 15 . Class I cavity was prepared and restored with either amalgam (Copalite varnish and Bestaloy) or composite (Z-250 with ScotchBond MultiPurpose: MP, Single Bond 2: SB, Clearfil SE Bond: CE and Easy Bond: EB as bonding systems). The DFF was measured from the intact tooth state through restoration procedures to 30 minutes after restoration, and re-measured at 3 and 7days after restoration. Inward fluid flow (IF) during cavity preparation was followed by outward flow (OF) after preparation, In amalgam restoration, the OF changed to IF during amalgam filling and slight OF followed after finishing. In composite restoration, application CE and EB showed a continuous OF and air-dry increased rapidly the OF until light-curing, whereas in MP and SB, rinse and dry caused IF and OF, respectively. Application of hydrophobic bonding resin in MP and CE caused a decrease in flow rate or even slight IF. Light-curing of adhesive and composite showed an abrupt IF. There was no statistically significant difference in the reduction of DFF among the materials at 30 min. 3 and 7 days after restoration (p > 0.05).

金鮮英,李順媛 한국의류학회 1985 한국의류학회지 Vol.9 No.3

The purpose of this study is to research into the thermal condition and the weight of clothes suitable for the officers engagged in light works in an air-conditioned room in summer. The Major findings are as follows: 1. Thermal conditions of the working environment are 24.5℃ (Dry bulb temp.), 68% (Relative humidity) and 2.6 m/sec (Air Velocity). 2. Total clothing weights are, 416.6 g/m2 (male) and 340.9 g/m2 (female). Underwear weights are 96.8g/m2 (male) and 85.1g/m2 (female). The latter turned out to be statistically significant in Sexual difference. 3. Means of the thermal sensation are 3.0 (comfortable; male) 2.7 ('Slightly cool'-'Comfortable'; female) and the relationship between clothing weights and thermal sensation proves to be significantly correlated in the case of female. 4. 66.7% of the women and 37.1% of the men feel sensation of coldness at the body's specific area and 79.5% of the women and 54.3% of the men reveals air-conditioning disturbance. 5. As the thermal sensation is close to 'cool-cold', sensation of coldness or air conditioning disturbance are showed up more frequently which is reversely related with weight of underwear. It is also proved that air conditioning disturbances are influenced by sexual difference in addition to sensation of coldness and thermal sensation. 6. According to the result of experiment, we can have the idea that at condition X1, the drop of limbs' skin temp. is remarkable. At condition X_2 skin temp. for distal limbs and mean skin temp. are raised and the falling degree is similar. At condition X_3, mean skin temp. and distal skin temp. are remarkably raised, and the falling degree decreases and the beats of pulse rate increase and diastoric blood pressure is lowered.

김선영 복식문화학회 2015 服飾文化硏究 Vol.23 No.4

This study is to assist in developing creative designs based on the humor available in the fashion world of Moschino. For the research method, this writing examined literature on humor and Moschino's fashion world and analyzed Moschino's fashion collection, show window, Maison Moschino, and collaborative products to conduct an empirical analysis of humor shown to the fashion media. The research results are as follows. The humor in Moschino's fashion appeared in the form of surrealistic humor with the depaysement technique, deconstructive wit in clothing, such as distortion, change, or exaggeration, and textual humor, including brand symbols, logos, and graffiti. Collection pieces indicated the brand's confirmative identity based on humor with the surrealistic depaysement technique and deconstructive wit through irregular phenomena, such as change, distortion, exaggeration, and illusion in clothing form. Additionally, such attributes added to Moschino's wit and humor in decorative costume components as graphic images, graffiti, and brand symbols, including smile, love, and reversal. The show window display delivered surprises and smiles through the production of surrealistic space borrowed from various objects. In particular, performance with surrealistic images helped to show the characteristics of parodic humor. Maison Moschino was a surrealistic space for the concept of the fairy tale and for practical experience, thus working as a communication channel for humor and emotion. Collaborative products also clearly reflected the identity of the designer's own humor, which showed scarcity value as well as differentiation.
