The purpose of this study were to compare school uniforms made in major and minor companies. Especially, purchasing motives, fitting satisfaction, and mending behaviors of school uniform were compared by middle and high school students. The most evident difference was exhibited in purchasing motive. Brand preference was the most important criterion in purchasing motive from a major company, while good pricing was the most important criterion in purchasing motive from a minor company. Apart from purchasing motive, purchasing behaviors such as fitting satisfaction, mending and mended part of school uniforms were not significantly different in relation to sex, grade, and type of company. These results indicate that major companies should consider lowering their prices and also adopt a high quality strategy for school uniform production. Minor companies need to identify areas of differentiation between themselves and larger companies, and produce niche market products that are for appealing to teenagers with a tendency to orient towards brands instead of quality. Furthermore, mature teenagers as consumers of school uniforms are receptive towards competition for reasonable price.

This study was conducted to provide basic information on developing highschool-uniform pants with more suitable fit and to suggest a sizing system for highschool girls' uniform pants that adequately reflects their body figures. To understand the features of high school girls' lower body type, the body measurement values of 833 girls from 16~18 years of age based on Size Korea(2010) were analyzed statistically. For the classification of lower body type for high school girls, a factor analysis and cluster analysis were conducted. The collected data were processed with the programs SPSS 18.0 for windows. The results in this study are follows: The lower body types for high school girls were divided into 3 groups. Body Type A is average stature but the biggest circumference, Type B is the biggest stature and the medium body type, Type C is the smallest stature and skeleton structure. KS size intervals were used for frequency distribution of height and waist for the lower body. Sizing system of the uniform company and frequency distribution of sizes were compared. Using the two-way distribution of highschool girls' waist circumference and hip circumference, sizing system considering body type distribution and high frequency distribution section of sizes was suggested. This study established new sizing system depending on lower body fixed as 26 number of sizes. The most suitable standard is fixed as 12 number of sizes ; 64-88, 64-91, 67-88, 67-91, 67-94, 70-91, 70-94, 70-97, 73-94, 73-97, 76-97, 76-100. The coverage is also calculated. And the coverage of new standard was 63.5%. The continuous study on the uniform pants sizing system of the obesity types is required.

This study aims to improve the fit of middle and high school girls' uniforms. This study researched on the sizing system reflecting their body figures. The results are as follows. First, to classify the middle and high school girls' figures, factor analysis, and cluster analysis were conducted. 4 factors were extracted for upper body of the middle school girls, and 5 factors were extracted for the highschool girls. For the lower body, 3 factors were extracted for both the middle and high school girls. The middle school girls were then divided into 4 groups for the upper body and 4 groups for the lower body. The high school girls were divided into 4 upper and lower body groups. Third, KS size intervals were used for frequency distribution of height and bust for the bodice, height and waist for the lower body. Sizing system of the uniform company and the frequency distribution of sizes were compared. As a result, sizing system of the uniform company and the frequency distribution overlapped very little. Fourth, sizing system considering body type distribution and high frequency distribution of sizes was suggested. As a result when 6 sizes were suggested 30% of the population was covered, and when 11 sizes were suggested 55% of the population was covered.

This study aims to improve the fit of high school girls' uniforms. This study researched on the fit of the recent high school girls' uniforms and developed a sizing system that adequately reflects their body figures. The results are as follows. First, the research showed that over 50% of the highschool girls wore their blouses too tight, whereas over 60% of the girls wore skirts that were appropriately fitted. Second, to classify the high school girls' figures, factor analysis and cluster analysis were conducted. 5 factors were extracted for upper body and 3 factors for the lower body. The girls were then divided into 3 groups for the upper body and 4 groups for the lower body. Third, KS size intervals were used for frequency distribution of height and bust for the bodice, height and waist for the lower body. Sizing system of the uniform company and the frequency distribution of sizes were compared. As a result, sizing system of the uniform company and the frequency distribution slightly overlapped. Fourth, sizing system considering body type distribution and high frequency distribution section of sizes was suggested. As a result, for the upper body, when 6 sizes were suggested, 43.9% of the population was covered and when 11 sizes were suggested, 58.3% was covered. For the lower body, when 6 sizes were suggested, 32.2% was covered, and when 11 sizes were suggested 58.9% of the population was covered.

Buckling and post-buckling behaviors of geometrically imperfect annular sector plates made from nanoparticle reinforced composites have been investigated. Two types of nanoparticles are considered including graphene oxide powders (GOPs) and silicone oxide (SiO₂). Nanoparticles are considered to have uniform and functionally graded distributions within the matrix and the material properties are derived using Halpin-Tsai procedure. Annular sector plate is formulated based upon thin shell theory considering geometric nonlinearity and imperfectness. After solving the governing equations via Galerkin's technique, it is showed that the post-buckling curves of annular sector plates rely on the geometric imperfection, nanoparticle type, amount of nanoparticles, sector inner/outer radius and sector open angle.

연구목적: 본 연구는 유색 및 백색 지르코니아 세라믹으로 제작된 코핑의 디자인에 따른 지르코니아 세라믹 코핑의 파절 하중과 변연 적합성을 평가한 것으로 그 결과를 임상에 응용하는데 도움을 주고자 하였다. 연구재료 및 방법: CAD/CAM system (Everset, KAVO Dental GmbH, Biberach, Germany)을 이용하여, 80개의 상악 제1 소구치 세라믹 코핑을 제작하되, 1그룹은 전체적으로 균일하게 0.3 mm로, 2그룹은 협면 0.3 mm 설면 0.6 mm, 3그룹은 전체 0.6 mm 균일하게, 4그룹은 협면 0.6 mm 설면 1.0 mm로 디자인하고, 유색 (I) 및 백색 (II) 지르코니아 코핑을 각 그룹당 10개가 되게 하였다. 소성직후와 조정 후 코핑의 변연 적합성을 Video Microscope System (sv-35, Sometech, Seoul, Korea)를 이용하여 100배율로 관찰하였고, 금속 주 모형에 코핑을 강화형 글래스아이오노머 시멘트로 합착 후 Universal Testing Machine (Instron 4467, Norwood, MA, USA)을 이용하여 파절 하중을 측정하여, one-way ANOVA test 를 시행하여 결과를 분석하였다. 결과: 1. CAD/CAM 지르코니아 코핑의 파절 하중은 1그룹, 2와 3그룹, 그리고 4그룹간에 유의성있는 차이를 보였으며 I4, II4의 파절 하중값이 가장 컸다. 2. 코핑의 디자인이 같고 색이 다른 그룹간의 비교에서는 전 그룹 모두 파절 하중값의 유의성은 없었다. 3. 소성 직후 변연 오차 측정값은 I2그룹을 제외한 전 그룹에서 협측 측정점에서 변연오차가 가장 큰 경향을 보였다. 4. 소성 직후 변연 오차 측정값은 I 그룹 지르코니아 그룹에서 그룹별 전체적인 변연적합도를 보았을 때 그룹간에 유의한 차이는 없었다 (P>.05). 5. 소성직후 변연 오차 측정값은 백색 지르코니아 그룹에서 그룹별 전체적인 변연 적합도를 보았을때 II1그룹의 변연 오차가 가장 컸다 (P<.05). 6. 소성직후 변연오차 측정값은 디자인이 같은 그룹의 유색, 백색 비교에서, I1와 II1그룹을 제외한 나머지 그룹에서 백색 지르코니아의 변연 적합도가 더 좋았다 (P<.05). 7. 내면 조정 후에는 색상화 및 지르코니아 코어 디자인에 따른 전 그룹간 변연 적합도의 차이는 없었다 (P>.05). 결론: 지르코니아 코핑 디자인과 색상화에 따른 변연 적합성은 소성 직후에는 다소 차이가 있었으나 내면 조정을 하면 임상 사용에는 무리가 없을 것으로 판단되었고, 파절강도 강화를 위해 코핑의 두께는 가급적 두꺼워야 하나, 가시면 (순면, 협면)의 심미성(반투명성)을 고려할 경우 가시면을 0.3 mm로 얇게 해도 파절 강도에 큰 영향을 주지 않는 것으로 사료되었다.

본 연구는 Kano모델을 활용하여 프랜차이즈 매장에 관한 다양한 품질요인들의 속성을 고객의 관점에서 분류하였다. 또한, 각 품질요인들이 고객의 만족 또는 불만족에 미치는 상대적 영향력을 분석해 보고자 만족지수와 불만족지수를 산출하였다. 자료 수집을 위해 외식 프랜차이즈 매장 방문 경험이 있는 서울 및 전국광역시 거주 성인들을 대상으로 온라인조사를 실시하였으며, 총 257개의 응답이 분석에 사용되었다. 분석 결과, 해당 품질요소가 충족이 되지 않는 경우 소비자의 불만으로 이어지는 요소에는 매장 청결도, 직원 친절도 및 숙련도, 편의시설 제공 등이 포함되는 것으로 나타났다. 프랜차이즈 사업에서 매장 간 음식메뉴의 구색, 가격, 품질수준, 인테리어, 고객서비스 절차 등의 표준화는 중요하게 생각되어 왔으나, 이 중 음식 가격의 동일성만이 고객의 불만족과 깊은 관계를 가지고 있었다. 충족이 되지 않아도 상관없지만 충족이 되는 경우 고객들의 호의적인 반응을 이끌어낼 수 있는 요소로는 외부기관으로부터의 수상 또는 인증 경력, 프랜차이즈 브랜드의 해외진출, 경품이벤트 및 사용금액에 따라 혜택을 주는 로열티 프로그램의 실시, 그리고 우수한 매장접근성이 해당되었다. 프랜차이즈 브랜드를 상대적으로 자주 이용하는 헤비유저의 경우, 정기적인 신메뉴 출시 또한 매력적인 품질요인으로 생각하고 있었다. 본 논문은 경영자가 우선적으로 관심을 두고 개선하여야 하는 부분과 경쟁력 확보를 위해 추가적으로 투자해야 할 부분이 어디인가에 대한 시사점을 제공해 준다는 점에서 연구의 의의가 있다.
