This research shows how fashion curation service consumers (both fashion and image consultants) reveal different aspects towards a preferred image type among the correlation of fashion curation service usage motivation and fashion shopping propensity. These preferences also included the purchase intentions for fashion display service products. This study surveyed 300 men and women between the ages of 20-30 who were the main consumers of fashion curation services. 'Convenience, fashion trend, and exploratory' increased purchase intentions for fashion shopping propensity, 'information search for utility, entertainment, and personal expression' increased purchase intentions for fashion curation services and 'brand identity, consumer lifestyle, and product information' increased factors for the fashion curation service preferred image type. Consumer preferences varied according to different fashion curation service image type; however, all consumer group syndicated a difference in fashion curation service actions. For instance, fashion curation service consumers preferred a consumer lifestyle image, convenience, hedonic shopping orientation, and personal expression motivation had a positive influence on product purchase intention. However, the shopping orientation of 'fashion trend, practical information exploration, and entertainment motivation' had an optimistic influence on product purchase intentions for fashion curation service consumers who preferred a brand identity image and a product information image.

Background/Aims: Despite the many reports of colonoscopy complications worldwide, few studies have been performed at the population level in Korea. In this study, a population-based study was performed to evaluate the incidence of post-colonoscopy perforations compared to a control group. Methods: Between January 2011 and December 2011, data for all cases (age over 45) who underwent a colonoscopy were collected from National Health Insurance Service using a random sampling method. The clinical characteristics and perforation incidence (within 30 days after the colonoscopy) of cases were identified, and cases were then compared with controls who had not undergone a colonoscopy. Results: Among 1,380,000 subjects, 31,177 cases and 62,354 controls were identified. Perforation occurred in 14 patients (0.04%) in the case group and one patient (<0.01%) in the control group (RR, 28.0; 95% CI 3.7-212.9, p<0.001). Subgroup analysis was followed according to the endoscopic procedure, gender and age. In subgroup analysis, colonoscopy-associated perforations occurred more in the therapeutic procedure (RR, 26; 95% CI 1.46-461.46), male (RR, 50; 95% CI 2.96-844.41), and age of 45-60 years (RR, 30; 95% CI 1.71-525.23). Conclusions: A colonoscopy procedure is related to an increased risk of perforation at the population level. In addition, the therapeutic procedure, male, and

Recently, as an alternative to the residential type, the interest in the hanok has increased and the spread and expansion for the creative succession of the hanok have been actively performed. In this study, we carried out load test to evaluate the durability according to the lattice structure of hanok window. Experiments were carried out by modularizing window lattice. Experiments were carried out using variables such as area, aspect ratio, type of paper, and type of load. As a result, the color hanji showed 27.5 ~ 200% higher load capacity than the yong yong yi. Both types of A200-12 specimens showed the highest yield strength. Also, the increase of the uniform distribution load with increasing area was evaluated as the aspect ratio was smaller. As a result of the load test of the concentrated load, the strength of the test specimen of the A100 series increased as the aspect ratio became smaller. In other words, A100-13 specimen with the smallest aspect ratio of 0.33 showed the greatest strength. Therefore, the durability of the lattice module of the window is considered to be better when the area of the module is larger and the aspect ratio of the concentrated load is smaller.

This study classified and analyzed the types of images posted on official accounts operated by domestic and foreign SPA brands on Instagram and Pinterest, which are image-based fashion curations, and performed a survey on preferred image types in the fashion curations of SPA brands. It aims to induce active apparel purchasing behavior of consumers through the suggestion of image types about fashion curations for effective communication between fashion brands and consumers. The survey to targets the 20s and 30s was carried out from October 23, 2015 until November 22 and conducted factor analysis, paired t-test. The above images were classified into four types based on previous studies: product images, brand images, lifestyle images, multiple images. The results of the survey were also divided into four factors in line with the classification of image types. Generally, foreign SPA brands(H&M, Uniqlo, Zara) used image-based fashion curation services more frequently than domestic SPA brands(8Seconds, Mixxo, Spao, Tngt). The analysis of image types in the fashion curations of SPA brands showed that product images accounted for the highest proportion of images used in the official accounts of SPA brands. However, the comparison of averages on the preferred image types of survey respondents showed that the users who had once visited the official accounts of SPA brands on Instagram and Pinterest preferred in the order of lifestyle information > product information > brand information > multiple information provided by SPA brands, which was statistically significant.

This study analyzes and classifies dresses by fashion designers worn in 10 fashion show seasons for hautecouture finales over the last five years(from 2011 S/S to 2015 F/W). The analysis of dresses are divided into 6 sections: classic image brands, new launching brands, designer``s image changing brands, continuous image brands, reentry collections brands, and non-continuous participated collection brands. In addition, fashion designer dress types based on this analysis are as follows. First, the type of individual image displayed positively appeals individual identity in fashion shows when wearing clothes like a fashion icon or model. Second, the type of personality orientation shows the personal image of the fashion designer rather than a brand image when expressing a favorite dress. Third, the type of reflecting the season trend shows seasonal trends by wearing a similar dress that match with the fashion show theme. Fourth, the type of consistent brand image means a dress by a fashion designer that meets a characteristic image of a brand that appeals to many people. Fifth, the type of original and typical fashion designer is a casual style(like a shirt and pants) that most people consider a fashion designers dress when leading and operating their own fashion show.

Domestic seafood has been widely used as a main protein source of the people, and demand for seafood is increasing year by year due to increase in national income and development of eating out culture. It is necessary to study to provide information to improve fishery income by improving efficiency and lowering inefficiency due to decline of earning of offshore fishery in recent 10 years. Both Stochastic Frontier Model and Data Envelopment Analysis were applied and the efficiency was compared and Wilcoxon test was conducted. Before the SFA analysis, the translog production function model was selected as a suitable model in this study. The estimation results of fishery production function show that the distribution of inefficiency follows a half-normal distribution, the technical inefficiency clearly exists in the production function, and the efficiency improves with time. In the DEA-SFA analysis, the average efficiency was estimated as 88% in the SFA, 49% under the Constant Return to Scale, and 70% under the Variable Return to Scale. As a wilcoxon test result, only one of 14 fisheries had commonality in fishery in the Constant Return to Scale. The yearly agreement of estimates were not consistent between SFA and CRS, while all the years showed the consistent estimates between SFA and VRS. Therefore, it was found that the estimates of SFA model should be considered to be consistent with those estimates in DEA model under the Variable Return to Scale.

김지우 ( Ji-woo Kim ),엄민 ( Min Um ),이재원 ( Jae-won Lee ) 한국목재공학회 2018 목재공학 Vol.46 No.1

본 연구에서는 해당화 부위별 열수추출물에 대한 항산화 활성을 분석하였다. 해당화의 부위별 추출물의 총 페놀성 화합물과 총 플라보노이드 함량은 잎에서 가장 높았으며, 각각 107.29, 24.28 mg/g로 나타났다. DPPH와 ABTS 라디칼 소거능은 꽃, 잎, 씨, 열매, 과육 추출물 순으로 활성이 높았으며, 꽃 추출물의 DPPH, ABTS 라디칼 소거능은 각각 IC50 = 0.87, 0.27 mg/mℓ로 나타났다. 항산화 활성이 가장 높았던 꽃과 잎 추출물에서는 gallic acid가 각각 4.51, 0.97 mg/g로 다른 부위별 열수추출물에서보다 높았다. 해당화 부위별 열수추출물을 분획한 결과(A-F), 꽃 추출물의 C 분획물에서 높은 항산화 활성을 확인하였다. 이것은 총 페놀성 화합물과 총 플라보노이드 함량(3305.43, 878.42 mg/g)에 의한 것이며, p-value < 0.001에서 총 페놀성 화합물과 총 플라보노이드의 함량이 증가할수록 라디칼 소거능이 증가하는 상관관계 결과와 일치하였다. 따라서 해당화 열수추출물은 식품, 화장품, 의약품 산업 등에서 천연 항산화제로 사용가능할 것이다. In this study, the antioxidant activities of hot water extracts of Rugosa rose (Rosa rugosa Thunb.) were evaluated. Total phenolic compounds (TPC) and total flavonoid compounds (TFC) were the highest in the leaf extracts at 107.29 mg/g and 24.28 mg/g, respectively. The DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) radical scavenging activity was in the following order: flower extract > leaf extract > seed extract > fruit extract. The IC50 values for DPPH and ABTS of the flower extract were 0.87 mg/mℓ and 0.27 mg/mℓ, respectively. The amount of gallic acid was higher in the flower (4.51 mg/g) and leaf extracts (0.97 mg/g) than in the other extracts. Among the fraction (A-F) of each extract, antioxidant activity was the highest in the C fraction of flower extract. It is due to high TPC (3305.43 mg/g) and TFC (878.42 mg/g). Statistical analysis revealed a strong correlation between TFC (or TPC) and radical scavenging activity at p-value < 0.001. Collectively, these results suggest that the hot water extracts of rugosa rose have potential antioxidant effects, and can be used in food, cosmetics, and the pharmaceutical industries.

Health Schedule 애플리케이션 설계 및 구현

김지우(Ji Woo Kim),이영민(Young Min Lee),이원주(Won Joo Lee) 한국컴퓨터정보학회 2024 韓國컴퓨터情報學會論文誌 Vol.29 No.3

In this paper, we design and implement the HealthSchedule app, which records exercise data based on the GPS sensor embedded in smartphones. This app utilizes the smartphones GPS sensor to collect real-time location information of the user and displays the movement path to the designated destination. It records the users actual path using latitude and longitude coordinates. Users register exercise activities and destination points when scheduling, and initiate the exercise. When measuring the current location, a lime green departure marker is generated, and the movement path is displayed in blue, with the destination marker and a surrounding 25-meter radius circle shown in sky blue. Using the coordinates of the starting point or the previous location and the current GPS sensor-transmitted location coordinates, it measures the distance traveled, time taken, and calculates the speed. Furthermore, it accumulates measurement data to provide information on the total distance traveled, movement path, and overall average speed. Even when reaching the destination during exercise, the movement path continues to accumulate until the completion button is clicked. The completion button is activated when the user moves into the sky blue circular area with a radius of 25 meters, centered around the initially set destination. This means that the user must reach the designated destination, and if they wish to continue exercising without clicking the completion button, they can do so. Depending on the selected exercise type, the app displays the calories burned, aiming to increase user engagement and a sense of accomplishment.
