  • This paper discussed the assessment of hand of Tencel denim fabrics finished by enzymatic hydrolysis. The subjective hand and the preference of Tencel denim fabrics were evaluated using the developed scale. The factors affecting consumers taste for Tencel denim fabrics were analyzed by statistics using SAS program. Also, the effects of cellulase treatment on the properties of Tencel denim fabrics were evaluated by the subjective hand measurements. The results are as follows: As the weight loss increased. fabrics were evaluated as finer, smoother, softer, warmer, more refined (surface properties), more compact and weaker (durability), more flexible, flossier, lighter, softer, thinner (sense of weight), more elastic, and less wrinkly (shape recovery). Fabrics were evaluated to have the dry touch regardless to the rate of weight loss (moisture properties). Overall hand preference of Tencel denim fabrics was in the side of not preferred. Hand of Tencel fabrics seems not to appeal to Korean people. Color preferences were not significantly different among five groups. The correlations between subjective hand and preference showed that fine, smooth, flexible, warm, refined, loose, soft, dry touches were preferred in Tencel denim fabrics.

  • This article is concerned with choice-based conjoint analysis versus rating-based and ranking-based conjoint analysis. Choice-based conjoint analysis has a definite advantage in that the respondent's task of choosing the most preferred profile from several competing profiles adequately mimics consumer marketplace behavior. It is crucial to design the choice sets appropriate for the choice-based conjoint. Thus, this article suggests a new method to design the choice sets that are well-balanced. It augments the balanced incomplete block design and then obtains the dual design of the result to accommodate various numbers of profiles. In consequence, the choice sets designed by the new method have the desirable characteristics that each profile is presented to the same number of respondents, and pairs of any two distinct profiles occur together in the same number of choice sets. The balancing of the design increases the efficiency of the conjoint analysis. In addition, the pair-comparison scheme can improve the quality of data through the identification of contradictory responses.

  • The objective of this study is to identify the critical dimensions of comprehensive quality and to prioritize them for improvement of the quality competitive advantage. The critical dimensions, sub-dimensions and measurement items of comprehensive quality were abstracted from literature of quality, and constructed a model of hierarchical structure. 115 experts in four groups(supplier, buyer, consultant, and professor) were participated in pair-wise comparison of quality dimensions, but some of these responses were removed because the overall consistency of evaluator judgements exceed the acceptable ratio of 0.10. The priorities of quality dimensions for industrial and consumption goods were calculated respectively using the analytic hierarchy process(AHP) approach. As a result, product quality had the highest weight of 0.65, followed by support quality(0.18) and service quality(0.17) for industrial goods while product quality also had the highest weight of 0.62, but service quality(0.22) was preferred over support quality(0.16) for consumption goods.

  • 본 연구의 목적은 형태초점 교수법과 오류수정 피드백이 영어 구문 학습에 효과적인지를 살펴보고, 이에 대한 학생들의 반응을 파악하기 위함이다. 연구 참여자들은 필수과목인 영어회화 강좌를 수강하는 8개 분반의 초급수준의 대학교 1학년 학생 122명이다. 이들 여덟 개 분반을 무작위로 세 그룹 즉 시각적 입력강화 집단(TIE group), 출력강화 집단(DICT group)과 통제집단(CG group)으로 나누어 사전 사후 평가 및 설문조사를 실시하였다. SPSS 21.0 for Window 프로그램을 사용하여 형태초점 교수법과 오류수정 피드백의 효과와 학생들의 영어수업에 대한 인식과 태도의 변화를 분석하였다. 연구결과, 본 연구에 활용된 형태초점 교수활동인 입력강화 및 출력강화 활동과 오류수정 피드백 모두가 학생들이 문법형태에 대한 지식을 향상시키는데 효과가 있는 것으로 나타났으며, 실험집단 모두가 형태초점 교수법과 오류수정 피드백에 긍정적인 인식과 태도를 보였고, 실험에 참여한 모든 학생들이 짝 활동(pair work)을 선호하였다. 또한, 통제집단(CG group)을 제외한 대부분의 시각적 입력강화 집단(TIE group)과 출력강화 집단(DICT group) 학생들은 영어수업에 대한 만족과 흥미를 보였던 것으로 나타났다. 이러한 실험 결과에 의거하여, 한국의 EFL 학습 환경에 있는 학생들의 영어 학습에 대한 개인적인 선호도를 고려하여 짝 활동 (pair work)의 형태로 목표문법형태 학습에 적절한 형태초점 교수법을 적용할 것을 제안한다.

  • 문맥의존 철자오류의 교정 방법은 크게 규칙을 이용한 방법과 통계 정보에 기반을 둔 방법으로 나뉘며, 이중 통계적 오류 교정 방법을 중심으로 연구가 진행되었다. 통계적 오류 방법은 문맥의존 철자오류 문제를 어의 중의성 해소 문제로 간주한 방법으로서, 교정 대상 어휘와 대치 후보 어휘로 이루어진 교정 어휘 쌍을 문맥에 따라 분류하는 방법이다. 본 논문에서는 본 연구진의 기존 연구 결과인 교정 어휘 쌍을 이용한 확률 모델의 성능 향상을 위해 어절 n-gram 모델을 기존 모델에 결합하는 방법을 제안한다. 본 논문에서 제안하는 결합 모델은 각 모델을 통해 계산된 문장의 확률을 보간(interpolation)하는 방법과 각각의 모델을 차례대로 적용하는 방법이다. 본 논문에서 제안한 두 가지 결합 모델 모두 기존 모델이나 어절 n-gram만 이용한 모델보다 높은 정확도와 재현율을 보인다.

  • This paper discussed the assessment of hand of cotton fabrics by enzymatic hydrolysis. The subjective hand and preference of denim fabrics finished by enzymatic hydrolysis were evaluated using the scale developed. The factors affecting consumers taste for denim fabrics were analyzed by the statistical technique. The effects of enzymatic hydrolysis on the properties of cotton fabrics were also evaluated by subjective hand measurements. The results are as follow; As the weight loss increased, evaluators thought that fabrics become finer, smoother, softer, warmer and more refined, and the sense of durability is sleeker and weaker, and the sense of weight is more flexible, flossier, lighter, softer, thinner. They didnt catch the change of moisture related properties according to the rate of weight loss. They also thought fabrics became more elastic, and less wrinklier as the weight loss increased. As the weight loss increased, the fabric was more preferred. The limited weight loss which changes the preference from \"dislike\" to \"like\" was 12.87%. The most preferred fabric was that with 12.87% of weight loss. It is supposed that the preference of fabric was related to the terms such as \"sum-se-ha-da\"(섬세하다), \"mai-ku-rup-da\"(매끄럽다), \"yoo-yon-ha-da\"(유연하다), \"too-bak-ji-an-da\"(투박하지 않다), \"chom-chom-ha-da\"(촘촘하다), \"gil-ki-da\"(질기다), \"kun-juk-goe-ri-ji-an-da\"(끈적거리지 않다), \"ku-kim-i-ka-ji-an-nun-da\"(구김이 가지 않는다).

  • 최근 일상생활 속 보행의 중요성이 강조되면서 보행권 보장 및 보행환경 조성을 위한 사업이 지역 곳곳에서 추진되고 있다. 선행 연구에서는 전주시 도로 이미지를 사용하여 보행환경 평가를 진행하고, 이미지 비교 쌍 데이터 세트를 구축하였다. 하지만 숫자로 표현된 데이터 세트는 보행환경 평가자들의 판단 기준을 일반화하거나 보행자가 선호하는 보행환경을 시각적으로 파악하기에 어려움이 존재한다. 따라서 본 연구는 웹 애플리케이션을 구축하여 데이터 시각화를 통해 보행환경 평가의 결과를 해석하는 방법을 제안한다. 의미론적 분할 결과를 활용하여 보행환경 평가자에게 영향을 미치는 보행환경 구성 요소를 분석한 결과, 보행자는 주로 'earth'와 'grass'가 많은 환경을 선호하지 않았고, 'signboard'와 'sidewalk'를 가진 환경을 선호하는 것으로 확인하였다. 제안된 연구는 향후 보행환경 평가의 참여자가 임의로 선택한 결과를 파악하고 분석할 수 있을 것으로 기대하며, 데이터에 대한 정제과정을 전처리로 수행함으로써 좀 더 향상된 정확도를 얻을 수 있을 것으로 판단한다.

  • To identify correlation between fresh meat and processed meat products, we performed canonical correlation analysis (CCA) to predict the relationship between pork supply and meat product production in Korea. Results of CCA showed a canonical correlation of 0.8576 in the first canonical pair (p<0.01). The production of meat products showed the highest correlation with pork import but the lowest correlation with the production of domestic pork. Although Korean consumer preferred meat products produced by fresh domestic pork, inexpensively imported pork with high share in meat products was supplied in the market. Therefore, securing domestically produced raw meat is important for expanding consumption of domestic meat products. Results of this study suggest that meat processor and pig producer can achieve the $6^{th}$ industrialization by combining the production of raw pork materials, meat processing, and sales service.

  • To date, no 8-oxoguanine-specific endonuclease-coding gene has been identified in Thermotoga maritima of the order Thermotogales, although its entire genome has been deciphered. However, the hypothetical protein Tm1821 from T. maritima, has a helix-hairpin-helix motif that is considered to be important for DNA binding and catalytic activity. Here, Tm1821 was overexpressed in Escherichia coli and purified using Ni-NTA affinity chromatography, protease digestion, and gel filtration. Tm1821 protein was found to efficiently cleave an oligonucleotide duplex containing 8-oxoguanine, but Tm1821 had little effect on other substrates containing modified bases. Moreover, Tm1821 strongly preferred DNA duplexes containing an 8-oxoguanine:C pair among oligonucleotide duplexes containing 8-oxoguanine paired with four different bases (A, C, G, or T). Furthermore, Tm1821 showed AP lyase activity and Schiff base formation with 8-oxoguanine in the presence of $NaBH_4$, which suggests that it is a bifunctional DNA glycosylase. Tm1821 protein shares unique conserved amino acids and substrate specificity with an 8-oxoguanine DNA glycosylase from the hyperthermophilic archaeon. Thus, the DNA recognition and catalytic mechanisms of Tm1821 protein are likely to be similar to archaeal repair protein, although T. maritima is an eubacterium.

  • The purposes of this study were to examine the slacks purchases and wearing satisfaction among old-aged women who were highly dissatisfied with their bodies and fit due to physical changes and to provide some basic data needed to develop slacks patterns to meet their needs. A survey was taken among 223 old-aged women aged 60~79 living in Seoul. Using the SPSS 12.0 program, the collected data were analyzed in descriptive statistics, t-test, and crosstab. The result were as follows: the most used place for them to shop slacks was a market(including the Dongdaemun and Namdaemun market), which was followed by a department store and a discount store in the order. As for their preference for slacks according to age, those who were in their sixties most preferred straight-line slacks, while those who were in their seventies semistraight-type slacks. As for fit for each body part according to age, there were significant differences only in crotch length. Those who were in their seventies were more dissatisfied with crotch length than those who were in their sixties, feeling that crotch length was short. As for their experiences of repair after purchasing a pair of slacks, 82.5% said they had such an experience. Most of the repairs with length, waist and slacks width involved in size reduction.
