This study aims to develop a life-friendly, wrap-one-piece style dance sports practice wear considering the physical characteristics of middle-aged, abdominally obese women. These types of practice wear allow people to enjoy exercise easily and to wear these garments as daily wear while meeting the requirements for dance sports wear. The three participants selected for this study were all women with five or more years of dance sports experience and were all average sized on Korea's abdominal obesity scale. In the first phase of the study, practice wear was created in a total of nine styles with three different styles of neckline depths for three different styles of dress skirt lengths. In the second phase of the study, the practice wear was created in 15 styles with five different styles of sleeve lengths for three different styles of waistline heights. After analyzing the design preferences of the participants, the fit preferences of the designs were evaluated and the final appearance was analyzed in order to suggest a pattern. The results of the subjects' first and second preference evaluations showed a preference for a 10 centimeter neckline depth, for high waistlines, and for elbow to wrist-length sleeves. The implementation of this research is expected to be extensive, as its results can be used as basic data for making lifestyle dance sports practice wear that covers the physical insecurities of middle-aged, abdominally obese women and enables them to enjoy their leisure time.

Objective : Filum transection is one of the most commonly performed operative procedure in pediatric neurosurgery. However, the clinical and pathological features as well as the surgical indication are not well-established. This study aimed to analyze the characteristics of patients who underwent transection of the filum during the last 10 years in a single institute. Methods : A total of 82 patients underwent transection of the filum during the period. As a general rule, we performed the transection in patients who are symptomatic or have abnormality in the urologic or neuromuscular evaluations. There were exceptions as asymptomatic patients who only fit the definition of thickened filum (width greater than 2.0 mm or conus level below L3 vertebral body) were operated by parent's wish or surgeon's preference according to radiological findings, etc. Results : Seventy-six out of 82 patients had fibrous tissue in the pathologic specimen of filum. Interestingly, patients who had glial cells were more correlated with no preoperative syrinx, and no progression of syrinx even for those who did have syrinx initially. Also, larger percentage of symptomatic patients had peripheral nerve twigs than asymptomatic patients. No difference in conus level or thickness of filum was found between patients with or without preoperative syrinx. Significantly more patients with syrinx (56%) were chosen to be operated without any symptom or abnormality in study i.e., solely based on radiological findings than those without syrinx (21%). The surgical outcome for syrinx was favorable, as all but one patient had either improved or static syrinx. The exceptional case had increase in size due to the upward displacement of the proximal end of the cut filum. Conclusion : This study evaluated the pathological, clinical, radiological features of patients who underwent transection of the filum. Interesting correlations between pathological findings and clinical features were found. Excellent outcome regarding preoperative syrinx was also shown.

This study aims to investigate the differences in blue jean styles and the visual images associated with them. To achieve this, literature reviews, case studies, and surveys were conducted. The results are as follows. 1) Based on previous studies, it was found that the design elements influencing the style of blue jeans and their visual images include waistline position, silhouette, details, decorations, and color. Additionally, differences in the preferences and visual evaluations of Korean and Chinese individuals regarding the style of blue jeans were confirmed. 2) Skinny blue jeans are typically characterized by a high waistline and a length that reaches the ankles, featuring a snug fit with stretchy fabric. Straight blue jeans, on the other hand, usually have a natural or high waistline and cover the instep, with a straight silhouette descending from the thigh to the hem. Bell-bottom blue jeans are primarily high-waisted and cover the instep with a silhouette forming a bell shape from the knee to the hem. 3) Korean and Chinese women in their 20s evaluated skinny, straight, and bell-bottom styles of blue jeans as having a 'casual' image. However, they also associated bell-bottom style blue jeans with 'unique' and 'attractive' images. Interestingly, Korean women described skinny-style blue jeans as making someone look 'youthful', while Chinese women perceived them as 'sophisticated', 'making the waist look thicker', and 'unassuming'. As for straight-style blue jeans, Korean women saw them as 'well-fitting', while Chinese women described them as 'making one appear taller', 'desirable', and 'free-spirited'.

This study aimed to assess the mobility and thermal comfort of personal protective equipment (PPE) among female healthcare workers, taking into account wearers' physique and PPE protection levels. A total of 16 participants (age: 26.3 ± 8.3 y, height: 161.5 ± 7.3 cm, body weight: 57.1 ± 11.0 kg, BMI: 21.9 ± 3.6), representing diverse body types, underwent four PPE conditions: L (Low_Plastic gown ensemble), M (Medium_Tyvek 400), H (High_Tyvek 800J with Powered Air Purifying Respirator [PAPR]), and E (Extremely high_Tychem 2000 with PAPR, Bib apron, and Chemical-resistant gloves). The mobility protocol consisted of 10 different tasks in addition to donning and doffing. The 10 tasks were repeated twice at an air temperature of 24.3 ± 0.1℃, 59±4%RH. Findings revealed a disproportionate relationship between PPE protection and wearer discomfort. Significant differences in clothing microclimate and total sweat rate were observed between the lowest (L) and highest (E) protection levels (p < 0.01), while distinctions among medium levels were inconclusive. Subjective evaluations favored conditions H and L over M and E (p < 0.05), indicating reduced heat, and humidity, increased comfort, and lower exertion. Instances of mobility discomfort, specially in the small body type group, underscored the need for a suitable PPE size system for Korean adult female medical workers. Furthermore, enhancements in gloves, shoe cover, and PAPR hood designs are essential for improving ease of movement and preventing hindrance.

Purpose - Satisfaction with service is evaluated according to customers' subjective judgment. The expected value of customer service and its evaluations depend on the customers' position. The customer recognizes two different forms of service levels. One is satisfaction and the other is dissatisfaction. Customers who are satisfied want to receive the service in future. However, those dissatisfied try to change the service. The service provider tries to improve the service. There are two different service cycles. One is the successful cycle and the other is the failure cycle. This study aimed to empirically determine the effects of the justice and authenticity of service recovery on customer behavioral intention through an integrated approach to cognitive justice and psychological authenticity. Research design, data, and methodology - Based on a literature review, justice of service recovery was categorized into three types: distributive, procedural, and interactive. Then, authenticity was added to obtain four independent variables, along with recovery satisfaction as a parameter. Behavioral intention, as an outcome variable, was divided into the repurchase intention and positive word-of-mouth. The model and hypotheses were created and measurement items were developed. A questionnaire survey of items concerning the service recovery experience at family restaurants was conducted on college students and residents in Gwangju from September 30 to October 31, 2013. A total of 400 copies of the questionnaire were sent out and 385 were returned. Respondents answered questions about the importance of, and satisfaction with service recovery on a 5-point Likert scale. Excluding 174 copies without service failure experiences and 7 inappropriate copies, 204 copies were analyzed using SPSS 21.0 for Windows and AMOS 20.0 to determine the reliability and validity of measurements. The hypotheses were tested through a goodness-of-fit analysis. Results - First, distributive justice positively affected recovery satisfaction. Second, procedural and interactive justice had no impact. Third, authenticity positively affected recovery satisfaction. Fourth, distributive justice had relatively stronger effects on recovery satisfaction than authenticity. Fifth, recovery satisfaction significantly affected repurchase intention and positive word-of-mouth and it proved effective in mediation. Finally, additional analysis was performed for descriptive statistics of the principal variables by various demographic characteristics and significant differences were found in gender, occupation, and so on. Conclusions - This study has academic significance as the fairness and authenticity of service recovery were investigated to reveal the effects on behavior. The findings could be applied to a wide range of service recovery strategies. However, there are some limitations. First, data was collected only from the residents of Gwangju and most respondents were aged 20-30. Future studies should target a wide range of areas and age groups. Second, because the questionnaire used in this study targets only convenience family restaurants, the results of this study cannot be generalized to all services companies. Future research should be done on a wide range of industries such as hotels, airlines, and hospitals, and perform a comparison between sectors.

Objective: To compare various models of diffusion-weighted imaging including monoexponential apparent diffusion coefficient (ADC), biexponential (fast diffusion coefficient [D_f], slow diffusion coefficient [D_s], and fraction of fast diffusion), stretched-exponential (distributed diffusion coefficient and anomalous exponent term [α]), and kurtosis (mean diffusivity and mean kurtosis [MK]) models in the differentiation of renal solid masses. Materials and Methods: A total of 81 patients (56 men and 25 women; mean age, 57 years; age range, 30-69 years) with 18 benign and 63 malignant lesions were imaged using 3T diffusion-weighted MRI. Diffusion model selection was investigated in each lesion using the Akaike information criteria. Mann-Whitney U test and receiver operating characteristic (ROC) analysis were used for statistical evaluations. Results: Goodness-of-fit analysis showed that the stretched-exponential model had the highest voxel percentages in benign and malignant lesions (90.7% and 51.4%, respectively). ADC, D_s, and MK showed significant differences between benign and malignant lesions (p < 0.05) and between low- and high-grade clear cell renal cell carcinoma (ccRCC) (p < 0.05). α was significantly lower in the benign group than in the malignant group (p < 0.05). All diffusion measures showed significant differences between ccRCC and non-ccRCC (p < 0.05) except D_f and α (p = 0.143 and 0.112, respectively). α showed the highest diagnostic accuracy in differentiating benign and malignant lesions with an area under the ROC curve of 0.923, but none of the parameters from these advanced models revealed significantly better performance over ADC in discriminating subtypes or grades of renal cell carcinoma (RCC) (p > 0.05). Conclusion: Compared with conventional diffusion parameters, α may provide additional information for differentiating benign and malignant renal masses, while ADC remains the most valuable parameter for differentiation of RCC subtypes and for ccRCC grading.

기업연상(corporate association)이 제품 평가(product responses)에 어떻게 영향을 미치는 가에 대한 연구가 부진하다는 Brown and Dacin(1997)의 문제 제기가 있은 후, 기업연상이 제품 판단에 미치는 영향과 과정에 대한 조절변수와 매개변수들을 파악하려는 연구가 진행되어 왔다. 본 연구에서는 기업연상의 두가지 유형인 CA(corporate ability) 연상과 CSR(corporate social responsibility) 연상이 성능과 재무위험에 미치는 영향력과 그 영향력을 조절하는 변수들을 조사하였다. 분석 결과에 의하면, 주효과(main effects)에 있어서는, 가설에서 기대한 바와 같이 CA 연상이 성능위험과 재무위험에 유의한 영향력을 갖는 것으로 나타난 반면, CSR 연상은 성능위험과 재무위험에 대해 유의한 영향력을 갖지 않는 것으로 나타났다. 조절변수로 인한 상호작용효과와 관련해서는, CA 연상이 성능위험과 재무위험에 미치는 주효과에 대해 제품범주 지식과 관여는 각각 유의한 조절효과를 나타내었다. 하지만, CSR 연상이 성능위험과 재무위험에 미치는 주효과에 대해서는 제품범주 지식과 관여의 조절효과는 나타나지 않았다. 이러한 연구 결과를 통하여 제품의 기능적인 속성에 대한 정보가 부족한 제품에 대해 소비자가 지각하는 위험을 감소시키기 위하여, 기업은 CSR 연상보다는 CA 연상에 대해 강조할 필요가 있다는 결론을 내리게 되었다.

최근 유통환경과 소비자 라이프스타일의 변화 속에서 단순히 제품을 판매하고 유통시키는 것에 그치는 것이 아닌 소매점자산을 증대시켜 고객을 획득하고 유지할 수 있는 차별화된 경쟁우위가 필요하게 되었으며, 이러한 대안으로 소매점 이미지의 중요성이 날로 커지고 있다. 이에 따라, 본 연구는 소매점의 이미지와 자아이미지 일치성이라는 요인과 고객기반 소매점자산과의 구조적관계를 조사하여 소비자들의 재이용의도에 어떠한 영향을 미치는지를 알아보고자 하였다. 본 연구의 가장 큰 학문적 기여점은 소매점자산에 영향을 주는 자아이미지일치성이라는 선행 요인을 찾아내는데 있으며, 또한 소매점자산이 재이용의도에 강력한 선행요인임을 확인하는데 있어서 기존의 연구들이 보여준 Second-order Construct 유형의 소매점자산척도와 결과 변수간의 단일차원 인과관계가 아닌, 소매점자산을 구성하는 각각의 요인들과 재이용의도의 좀 더 구체적인 변수간의 구조적관계를 실증할 수 있게 되었다. 본 연구는 소매점과 자아의 이미지일치성을 두 가지 차원(실제 자아이미지일치성, 이상적 자아이미지일치성)으로 나누고 소매점자산의 구성요소인 소매점인지, 소매점연상, 지각된 소매점 품질, 소매점충성도에 어떠한 영향을 미치는가를 분석하고 자아이미지일치성을 토대로 평가된 소매점자산 요인들이 소매점의 재이용의도에 미치는 영향을 분석하여 소매점의 이미지의 관리와 투자에 대한 마케팅 측면의 중요성을 제시하고 있다. 연구모델에 대한 분석결과 소매점-실제 자아이미지일치성과 소매점-이상적 자아이미지일치성 모두 모두 소매점자산 요인들에 긍정적인 영향을 미쳤으며, 그 중 이상적 자아이미지일치성이 소매점자산 요인들에 미치는 상대적인 영향력이 더 크게 나타났다. 또한 소매점자산을 구성하는 각각의 요인들은 소비자의 소매점 재이용의도에 긍정적인 영향을 주는 것으로 나타났다. 이는 타겟 소비자들의 자아 이미지와 소매점의 상징적 이미지를 일치시키는 마케팅 노력을 통해 소비자들과 소매점 사이의 강력한 감정적 결속이 형성되어 해당 소매점의 자산을 높게 평가하고 지속적인 이용의도를 가져올 수 있음을 시사한다.
