Domestic apparel products labeled as 'Made in Korea' in the Chinese market are recognized as a high quality products due to the influence of the Korean Wave (Intergen Consulting Group, 2007). This study analyzes the patterns and order arrangement types of a fashion brand company commissioned to produce apparel in Seoul, Korea in order to rebuild a network of small sewing factories scattered in Korea, reorganize operations, and to find the possibility of regenerating the Korean sewing industry by establishing contact points with domestic sewing factories. We surveyed 100 apparel brand companies in Seoul listed in the 2014/2015 Korea Fashion Brand Annual (Apparel News, 2014) and conducted a questionnaire survey on the company's general management status, type of fabric materials dealt with, and major contact points and methods of production handling. The frequency analysis indicated that the main production material with cloth type was woven fabric with ladies' clothes. The Planning MD team has the highest rate of ordering production with delivery method to the production factory after purchasing fabric and trims. Most respondents answered that they would select a production factory based on recommendations from acquaintances. This was due to a lack of no objective indicator provided by the sewing factory at present and the absence of objectively proceeded communication with brand companies. In this study, we analyze various conditions and measurements for production arrangements from a fashion brand company to revitalize sewing factories in Korea.

Objective: This study was performed to evaluate gender and age differences in hygienic behavior among the general population, focusing on hand-washing habits and the microbial load of hands. Methods: A self-administered questionnaire survey and a separate microbial examination were performed. The Pearson's correlation between hand-washing habits and microbial load was analyzed. Results: In the questionnaire survey on hand-washing habits, gender differences were found in hand-washing frequency, use of hand-washing agents, and hand drying methods (p<0.05). Age differences were found in numbers of washing parts of the hands and also in hand drying methods (p<0.05). Females showed better habits washing hands than did males, as did older people compared to younger. In the microbial examination of indicator bacteria on their hands, younger people tended to show a higher load of total aerobic bacteria than did the older, and females showed a higher load of total coliforms than did males (p<0.05). There were significant relationships between the load of total aerobic bacteria and hand-washing frequency, duration, and method of turning-off water (p<0.05). Conclusions: Although females were expected to show a better practice of hand-washing than were males based on the survey results, they showed a higher level of total coliforms in the hand examination. The older age group showed better hand-washing habits than did the younger age group and had less total aerobic bacteria on their hands. These inter-gender and age differences highlight the need for development and implementation of gender-and age-specific educational programs or campaigns.

본 연구는 취약계층을 대상으로 건강정도를 객관적 지표인 체질량지수를 통해 비만 정도의 지역별 격차를 공간적으로 규명해보고자 한다. 따라서 체질량지수가 공간적으로 높은 값과 낮은 값을 가지는 군집패턴을 보이는 지역을 추출하고 이 지역의 특성을 분석하였다. 분석 결과, 비만인구비율의 I 통계량은 0.07, z-score은 4.39으로 나타나, 공간자기상관성을 확인하였다. z-score의 경우 최대 임계값인 2.57보다 훨씬 크게 나타났다. 이는 사회취약계층 비만율이 지역별 격차를 보이며, 이러한 격차가 공간통계적으로 유의함을 의미한다. 이러한 비만 취약지역과 양호지역에 대한 지역별 환경을 비교 분석한 결과는 취약지역의 경우 대중교통성이 좋지 않고 쉽게 이용할 수 있는 공원이 적으며 단독 다세대 주택이 밀집한 지역으로 확인되었다. 본 연구의 분석 결과는 기존 연구들이 소홀했던 사회취약계층의 건강에 대하여 공간적인 시사점을 제공한다는 점에서 의미를 지닌다.

Objective : Rheumatoid arthritis (RA) is known to involve the cervical spine up to 86%. It often causes cervical instability like atlantoaxial subluxation (AAS), subaxial subluxation, and vertical subluxation (VS). In order to find the relation between RA and cord compression, we will evaluate the characteristics and risk factors of basilar invagination (BI) and cervicomedullary junction (CMJ) compression. Methods : From January 2007 to May 2015, 12667 patients administrated to Hanyang University Medical Center. Four thousand three hundred eighty-six patients took cervical X-ray and 250 patients took cervical computed tomography or magnetic resonance imaging. Radiologic parameters, medication records were obtained from 242 patients. Multivariate logistic regression analysis was performed with correlation of CMJ compression, basin-dental interval (BDI), basin-posterior axial line interval (BAI), pannus formation, BI, and AAS. Results : In the point of CMJ compression, atlantodental interval (ADI), posterior-atlantodental interval, BAI, AAS, and BI are relatively highly correlated. Patients with BI have 82 times strong possibility of radiologic confirmed CMJ compression, while AAS has 6-fold and pannus formation has the 3-fold possibility. Compared to the low incidence of BI, AAS and pannus formation have more proportion in CMJ compression. Furthermore, wrist joint erosion was correlated with VS and AAS. Conclusion : BI has a very strong possibility of CMJ compression, while AAS and pannus formation have a high proportion in CMJ compression. Hence bilateral wrist joint erosion can be used as an indicator for the timing of screening test for cervical involvement. We suggest the early recommendation of cervical spine examination for the diagnosis of cervical involvement in order to prevent morbidity and mortality.

The objective of this study was to investigate the health status and nutritional intake of the old population living in Soonchang, Jeollabuk-do, Korea. 69 subjects aged 65 years and older were recruited in July 2016. The WHR, was significantly higher in elderly male group than elderly female group (p<0.05), but both groups had abdominal obesity (0.85 and over). T-score mean of elderly male and female groups were below $-2.5mg/cm^3$ that they were osteoporotic. In the elderly male group, the higher concentrations of creatinine, homocysteine and uric acid were found to be significantly unfavorable factors (p<0.001, respectively). The blood vitamin $D_3$ levels of elderly male group was significantly higher than that of elderly female group (p<0.05). The physical activity and self-rated health were significantly higher in elderly male group than in elderly female group (p<0.05, p<0.01, respectively). The nutrient intakes of male group were found to be significantly favorable factors than in female group. The score of mini nutrition assessment was significantly lower in elderly female group than in the elderly male group. These results could be useful to plan effective strategies to increase the health-life expectancy and the prevention of disease of Korean elderly people living in rural areas.

Objective: The shock index (SI), as a trauma triage tool, is a capable clinical indicator of hemodynamic instability and hypovolemic shock, but the conception of SI is contradictory to shock. The reverse shock index (RSI) was introduced recently, but its utility has not been sufficiently proven. Methods: This study examined the RSI utility by evaluating the procedures performed at an emergency department (ED) and the associated outcomes when the RSI is used alone or in combination with the Korean Triage and Acuity Scale (KTAS). This was a retrospective study conducted by including data of 4,789 adult trauma patients for a year. The clinical variables, procedures performed on patients, and outcomes were investigated. The median RSI was 0.9 in the RSI<1 group. Results: Patients in the RSI<1 group had a higher odds of requiring procedures at the ED and for experiencing worse outcomes: intubation (odds ratio [OR], 5.4; 95% confidence interval [CI], 2.3-13.1; P<0.001), chest tube insertion (OR, 6.5; 95% CI, 0.4-111.84; P<0.001), use of emergency drugs (OR, 3.6; 95% CI, 1.5-8.5; P<0.001), circulatory support (OR, 5.4; 95% CI, 2.3-12.9; P<0.001), intensive care unit admission (OR, 3.5; 95% CI, 1.8-6.8; P<0.001), and mortality during the ED stay (OR, 20.4; 95% CI, 5.5-75.7; P<0.001). In the group with KTAS 1-3, trends similar to those in the RSI<1 group were observed. Patients with RSI<1 had more severe injuries and poorer outcomes than those with $RSI{\geq}1$, regardless of whether the RSI was used alone or in combination with KTAS. Conclusion: RSI can provide an appropriate triage with concurrent KTAS use.

Objective: This study examined the initial partial pressure of carbon dioxide ($PCO_2$) as a possible indicator of prehospital ventilation and its association with prehospital i-gel in out-of-hospital cardiac arrest (OHCA) patients. Methods: The demographics and arrest parameters, including i-gel insertion and initial arterial blood gas analysis, of OHCA patients who visited the emergency department were analyzed retrospectively. Linear regression analysis was performed to examine the association between i-gel insertion and the initial $PCO_2$. Results: A total of 106 patients were investigated. Fifty-six patients had prehospital i-gel insertion and 50 patients did not have a prehospital advanced airway. The initial $PCO_2$ was higher in the i-gel group than the no advanced airway group (105.2 mmHg [77.5-134.9] vs. 87.5 mmHg [56.8-115.3], P=0.03). Prehospital i-gel insertion was associated with a higher initial $PCO_2$ level (${\beta}$ coefficient, 20.3; 95% confidence interval, 2.6-37.9; P=0.03). Conclusion: Prehospital insertion of i-gel was associated with higher initial $PCO_2$ values in OHCA patients compared to no advanced airway.

The building energy performance indicator, called Energy Performance Index (EPI), has been used for the past decades in South Korea. It has a list of design variables assigned with weighting factors (a, b). Unfortunately, the current EPI method is not performance-based but very close to a prescriptive rating. With this in mind, this study aims to propose a new performance-based EPI method. For this purpose, a global sensitivity analysis method, Sobol, is employed. The Sobol method is suitable for complex nonlinear models and can decompose all the output variance due to every input. The Sobol sensitivity index of each variable is defined as 0 to 1 (0 to 100%), and the sum of all sensitivity indices is equal to 1 (100%). In this study, an office building was modeled using EnergyPlus and then the Latin Hypercube Sampling (LHS) was conducted to generate a surrogate model to EnergyPlus. The sensitivity index was suggested to replace weight (a) in the existing EPI. In addition, the discrete weight (b) in the existing EPI was replaced by a set of continuous regression functions. Due to the introduction of the sensitivity index and the continuous regression functions, the new proposed approach can provide far more accurate outcome than the existing EPI (R²: 0.83 vs. R²: 0.01 for cooling, R²: 0.66 vs. R²: 0.01 for total energy). The new proposed approach proves to be more rational, objective and performance-based than the existing EPI method.

Objective: To investigate the cephalometric predictors of the future need for orthognathic surgery in Korean patients with unilateral cleft lip and palate (UCLP) despite long-term use of facemask with miniplate (FMMP). Methods: The sample consisted of 53 UCLP patients treated by a single orthodontist using an identical protocol. Lateral cephalograms were taken before commencement of FMMP therapy (T0; mean age, 10.45 years), after FMMP therapy (T1; mean age, 14.72 years), and at follow-up (T2; mean age, 18.68 years). Twenty-eight cephalometric variables were measured. At T2 stage, the subjects were divided into FMMP-Nonsurgery (n = 33, 62.3%) and FMMP-Surgery (n = 20, 37.7%) groups according to cephalometric criteria (point A-nasion-point B [ANB] < -3°; Wits-appraisal < -5 mm; and Harvold unit difference [HUD] > 34 mm for FMMP-Surgery group). Statistical analyses including discrimination analysis were performed. Results: In FMMP-Surgery group, the forward position of the mandible at T0 stage was maintained throughout the whole stages and Class III relationship worsened with significant growth of the mandibular body and ramus and counterclockwise rotation of the maxilla and mandible at the T1 and T2 stages. Six cephalometric variables at T0 stage including ANB, anteroposterior dysplasia indicator, Wits-appraisal, mandibular body length, HUD, and overjet were selected as effective predictors of the future need for surgical intervention to correct sagittal skeletal discrepancies. Conclusions: Despite long-term use of FMMP therapy, 37.7% of UCLP patients became candidates for orthognathic surgery. Therefore, differential diagnosis is necessary to predict the future need for orthognathic surgery at early age.
