This study examines the color characteristics of the usage of the color pink in menswear by analyzing its usage status and method. It involves an empirical research method establishing the frame of the study through a document study centered on trend, gender neutral considerations, and the utilization of the color pink in men's fashion, by analyzing the characteristics of color and tone by extracting the pink color shown in menswear collections as well as analyzing and categorizing the fashion image and genderless characteristics. Analyzing the color and tone of the pink color shown indicate that bright, light and pale tones had higher proportions. Pink color can also be said to be utilized as a design element that gives off a younger and more vital color image in menswear. Further, the use of brighter and softer pink colors can be interpreted as reflecting modern society's demands of masculinity to change into a more sophisticated and soft image. To analyze the characteristics of the color pink utilized in gender neutral fashion, fashion images were presented as the analysis standard. An image grouping technique was used to classify pink while utilizing genderless types-fashion style. The result showed that even with the same pink color, the fashion image can vary with different methods of expression in terms of clothes and styling. The results of this study can serve as basic data for planning fashion design concepts as it analyzed pink-using fashion images and the genderless concept type.

Contrary to the traditional text-based information, 4S(GIS,GNSS,SIIS,ITS) information can contribute to the citizen's welfare in upcoming era. Recently, GSIS(Geo-Spatial Information System) has been applied and stressed out in various fields. As analyzed the data from GSIS arena, the position information of objects and targets is crucial and critical. Therefore, several methods of getting and knowing position are proposed and developed. From this perspective, Position collection and processing are the heart of 4S technology. We develop 4S-Van that enables real-time acquisition of position and attribute information and accurate image data in remote site. In this study, the configuration of 4S-Van equipped with GPS, INS, CCD and eye-safe laser scanner is shown and the merits of DGPS/INS integration approach for geo-referencing is briefly discussed. The algorithm of DGPS/INS integration fur determination of six parameters of motion is eccential in the 4S-Van to avoid or simplify the complicated computation such as photogrammetric triangulation. 4S-Van has the application of Laser-Mobile Mapping System for three-dimensional data acquisition that merges the texture information from CCD camera. The technique is also applied in the fields of virtual reality, car navigation, computer games, planning and management, city transportation, mobile communication, etc.

Monitoring water surface has become one of the most prominent areas of research in addressing environmental challenges.Accurate and automated detection of watersurface in remote sensing imagesis crucial for disaster prevention, urban planning, and water resource management, particularly for a country where water plays a vital role in human life. However, achieving precise detection poses challenges. Previous studies have explored different approaches,such as analyzing water indexes, like normalized difference water index (NDWI) derived from satellite imagery's visible or infrared bands and using k-means clustering analysis to identify land cover patterns and segment regions based on similar attributes. Nonetheless, challenges persist, notably distinguishing between waterspectralsignatures and cloud shadow or terrain shadow. In thisstudy, our objective is to enhance the precision of water surface detection by constructing a comprehensive water database (DB) using existing digital and land cover maps. This database serves as an initial assumption for automated water index analysis. We utilized 1:5,000 and 1:25,000 digital maps of Korea to extract water surface, specifically rivers, lakes, and reservoirs. Additionally, the 1:50,000 and 1:5,000 land cover maps of Korea aided in the extraction process. Our research demonstrates the effectiveness of utilizing a water DB product as our first approach for efficient water surface extraction from satellite images, complemented by our second and third approachesinvolving NDWI analysis and k-means analysis. The image segmentation and binary mask methods were employed for image analysis during the water extraction process. To evaluate the accuracy of our approach, we conducted two assessments using reference and ground truth data that we made during this research. Visual interpretation involved comparing our results with the global surface water (GSW) mask 60 m resolution, revealing significant improvements in quality and resolution. Additionally, accuracy assessment measures, including an overall accuracy of 90% and kappa values exceeding 0.8, further support the efficacy of our methodology. In conclusion, thisstudy'sresults demonstrate enhanced extraction quality and resolution. Through comprehensive assessment, our approach proves effective in achieving high accuracy in delineating watersurfaces from satellite images.

It's not easy to renew old brand of over 50 years history to the tastes of new consumer of our time. Most of national brands that has a history of some 20 years in Korea have strove for continuation and growth of brand to no avails, which can be taken as a good example of current situation. For instance, C company, one of the National brand of US which has a history of 51 years, has made its position secure as a fashion group and based itself on a sound foundation by establishing new marketing strategy and completing successful brand renewal in the process of strategic M&A with Italian company. Those successful marketing strategies are as follows. 1) they regarded both market and consumer oriented marketing activity as company's highest priority strategy and put great emphasis upon concentration on target market and reestablishment of brand image of business casual wear. 2) Setting up and operating planning team composed of merchandizer alone in Milano, they set the direction of plan on the basis of concentrated research on potential item in market according to thorough market research done by buying office in Korea, branch office in Hong Kong and buyer in US prior to blueprint planning for season. 3) Great emphasis was placed on business which focused on intensive presentation of basic key item for apparel career women who are main consumer group in the midium-low prices market in US and on supplementation of size and color. they named this line 'collectibles' and helped their customer develop their own clothes plan without worrying about the change of color and fabric by supporting same fabric and color throughout the year and enabled them to add variation easily by supplementing new trend item. 4) Company set black as a main color that lots of apparel career women find easy to care and to express their own image and presented them with pebble which belongs to navy and beige and added fashion color such as wine and brown etc as season goes by. They constructed basic line in order for their customers to coordinate purchased item with new one or to add them to present collection, and to achieve efficient sale by setting up strategy which allows this cross coordination and changing pattern occasionally. 5) Though basic jacket for 99$, short slim skirt for 49$ are products within midium-low prices range, in the material planning stage aiming at production of item that has both resonable function appealing to consumer and is fashionable, synthetic material had to be used as a main source due to price competitiveness. Despite this situation, considering comfortable sense of fit and refined drape of silhouette that has no sign of cheap material, whole collectible line was divided into two items, which contributed to reduction of cost. In case of material that is composed of triacetate and polyester in 70 to 30 ratio, was used up to 4 million yard, which allowed drastic curtailment of cost accompanied by concentration. In case of 'collectibles' line, using Korean material mainly, C company chose to have their product sewed in Southeast Asian countries where transportation is well developed and both productivity and quality verified by operating global production system which aiming at cutdown of cost through outsourcing production from the country where labor cost is low and getting finished product. Polarization between present consumers telling us that consumers with the mind of middle classes in the past no longer exists between consumers who seek after only fine article of highest quality and wise consumers who are sensible enough to judge bubble on correlation between price and quality. To cope with this change in new consumer mind, apparel makes changing their policy so as to produce item that has reasonable quality and falls within affordable price range anywhere in the world. and they're striving to get out of difficult situation by operating global marketing strategy which stresses separation of planning, production and sale and sensibility of fashion shared worldwide. The marketing strategy of C company can be exemplified as a successful one.

This descriptive study was done to identify factors influencing sexual satisfaction in women who had had a hysterectomy and to compare these with women who had not had a hysterectomy. The purpose was to contribute theoretical understanding on which to base nursing care planning. One group of subjects were 156 women who had had a hysterectomy, between one and 18 months post surgery, living with their spouse, having no complications, and menstruating before surgery. The other group of subjects were 282 healthy women who were living with their husbands and menstruating. The study tool consisted of 108 items including item concerning personal characteristics, characteristics related to the hysterectomy, husband's support, body image, emotions, attitude toward the sexual relationship, knowledge of sexuality, sexual behavior, and sexual satisfaction. Sexual satisfaction was measured by a tool based on Derogatis Sexual Function Inventory. The range of the internal level of the study tool was from. 5208 to .9462. Data collection was done during the period from June 20 to Aug.20, 1989. The same questionnaire was used of data collection for both groups, but a mail survey method was used for the women who had had a hysterectomy, and an interview method was used for the women who had not had a hysterectomy. Data analysis was done using frequency, ratio, mean and S.D. for the characterstics of the subjects and level of sexual satisfaction. t - test or ANOVA was used for the differences between the groups with regard to the general and hysterectomy related characteristics. The relationship between the score for sex life related factors and the level of sexual satisfaction was analyzed using the Pearson Correlation, and the influencing factors on sexual satisfaction were analyzed by stepwise multiple regression. The results of this study were as follows ; 1. Mean age and income level were the only general characteristics for the two groups that were significantly different. The mean age, and income level of the group who had had a hysterectomy were 45years, and 1,150,000 won respectively, and for those who had not had a hysterectomy, 41 years and 999,000 won. 2. There was no statistical difference of the sexual satisfaction score between the two groups. 3. There was differences in the factors influencing sexual satisfaction between the two groups. Factors influencing sexual satisfaction for the group who had had a hysterectomy were husband's support (R＝.5793, P＝.000) and the women's Knowledge of sexuality(R＝.6670, P＝.000) (total variance : 33.56). On the other hand, emotional status(R＝.4294, P＝.000), sexual behavior(R＝.4294, P＝.000), husband's support(R＝.5274, P＝.000) and attitude towards sexual relations (R＝.5412, P＝.000) (total variance : 54.12) were the factors influencing sexual satisfaction in the group who had not had a hysterectomy. Since husband's support and sexuality knowledge were identified as factors influencing sexual satisfaction of women who have had a hysterectomy, it can be concluded that, before a woman who has had a hysterectomy is discharged from hospital, nurses should include strategies in the nursing care plan that will promote husband's support and the women's knowledge of sexuality.

그동안 교통관리에서 적용되던 드론 관련 연구는 도로나 차량을 검지하고 추적하는 연구가 대분이었다. 교통분야에서 영상이미지를 분석하는 목적은 기존 교통자료 수집체계(차량검지기, DSRC 등)의 한계를 극복하기 위함이다. 그런 의미에서 드론은 상당히 좋은 대안이나 최대 비행시간이 제한되어 있어 기존 수집체계를 대체하기 보다는 보완적 성격으로 활용되는 것이 타당하다. 따라서 교통조사분석을 위한 드론 활용방안에 대한 연구가 더 필요한 실정이다. 교통문제의 경우 특정 구간이나 지점에서 발생한 문제가 네트워크 전체로 확대되는 경우가 많아 드론을 이용하여 이러한 구간들에 대한 분석이 필요하다. 본 연구는 교통조사분석 활용을 위한 기초 연구로 드론으로 촬영된 고속도로 구간(800~1000m)을 단위 구간으로 분할하여 교통류 변수들을 추출하였다. 또한 영상기술의 발전으로 고고도에서 영상 촬영을 수행하였다.

This research was done to clarify the factors related to sexual satifaction in women who have had a hysterectomy, and to idenify which factors had statistically significant influence of sexual satisfaction of the subjacts. The objective of this study was to identify the variables related to sexual adaptation which might be changed by nursing intervention. This was a cross-sectional descriptive correlation study. There were 230 subjects in the study, and they were selected by a convenient sampling method. The tool. for this study was developed by the researcher through modification of the Dergatis Sexual Function Inventory(DSFI). A pilot study was done to determine the necessary modifications. Data collection was done between Sept. 1987 and Du. 1987 using a mailed questionnaire. The characteristics of the subjects were as follows : The mean age of the subjects was 42.3 years and 204(87.4%) of the subjects had nine or more years of education. The mean income of the subjects was 85.8870 won / month, and 179(77%) of them were housewives. The mean number of pregnancies and children were 4.9 and 2.5 respectively. Oophorectomies were included in the surgery for 66(28.7%) of the subjects. Only 12(5.2%) were planning to have more children. Only 88(38.3%) of the subjects had received information prior to the surgery regarding health problems related to the operation and less than half, 111 (48.3%), had received this kind of information before discharge. Lay persons were the source of information about the post-operation status for 196 (85.2%) of the subjects, but the content of the information did not significantly influence the sexual satisfaction score. Only 16(7.0%) of the subjects said they regretted having a hysterctomy while 102(44.3%) said they were pleased to have had a hysterectomy. Ninety (39.1 %) of the subjects reported that their husbands had “stress” and 164(71.3%) of the subjects reported “stress”. The results of this study are summarized as follows : 1. The mean score for sexual satisfaction of the subjects was 34.24 with a possible maximum score of 50.00. Eighty two(35.8%) were responded that they were satisfied with their sexual life but 61 (26.5%) were responded that they were dissatisfied with their sexual life 2. The following 15 factors extracted from the results of the data analysis were significantly related to sexual satisfaction(p＜.05) ; support of husband, body image, emotion, knowledge of sex, menopausal symptoms, sexual behavior, the feelings the subjects had about the hysterectomy, stress for both subject and husband, the number of children, health information given before operation, job, age, level of education and income. The five most important factors influencing sexual satisfaction were identified by using stepwise multiple regression analysis. The most important factor was support of husband, which explained 17.83% of the total variance. The remaining factors in order of significance were : Knowledge of sex, income, job, and emotional status. Those five factors explained 35.16% of the sexual satisfaction. In conclusion, for the care of women who are going to be discharged from hospital after having had a hysterctomy, nurses have to work with the husbands to help them to understand the importance of their support. Nurses also need to make sure that the subjects have an adequeate knowledge of sexual life after a hysterectomy. Also nursing interventions should focus on subjects who do not have a job, who are of low economic status, and the subjects who are under the unpleasant mood.
