The U-Net architecture-based segmentation models attained remarkable performance in numerous medical image segmentation missions like skin lesion segmentation. Nevertheless, the resolution gradually decreases and the loss of spatial information increases with deeper network. The fusion of adjacent layers is not enough to make up for the lost spatial information, thus resulting in errors of segmentation boundary so as to decline the accuracy of segmentation. To tackle the issue, we propose a new deep learning-based segmentation model. In the decoding stage, the feature channels of each decoding unit are concatenated with all the feature channels of the upper coding unit. Which is done in order to ensure the segmentation effect by integrating spatial and semantic information, and promotes the robustness and generalization of our model by combining the atrous spatial pyramid pooling (ASPP) module and channel attention module (CAM). Extensive experiments on ISIC2016 and ISIC2017 common datasets proved that our model implements well and outperforms compared segmentation models for skin lesion segmentation.

Background: While the application of procedural methods to solve the infertility problem has increased, the decline in the quality of life of women who experience infertility has been disregarded. Methods: This qualitative study used phenomenological analysis of data collected from 13 women with infertility in South Korea to reveal the subjective meaning of physical experiences perceived by women over the course of treatment. Results: Upon analyses of the treatment experiences of women with infertility in South Korea via a phenomenological analysis method, 10 themes were extracted and integrated into four theme clusters ("Perceiving infertility," "The body that gives birth," "A process in an endless tunnel," "Caring for my marginalized identity"). Conclusion: The results of this study suggest that women with infertility in South Korea perceived their own bodies as givers of birth living in traditional and patriarchal societies. A contextual flow proceeded to the final stage of women caring for their marginalized identity, which had suffered throughout the course of their infertility journey.

Nosema sp. infection in the Indian tasar silkworm, Antheraea mylitta exerts a complex of influences on its host. The instar duration was extended significantly (P<0.001) except in $1^{st}$ instar. The infected larvae took about 48 days to reach the spinning stage against 40 days in the uninfected ones. The final weight attained by the larva at the end of each instar of development declined significantly following infection, as did weight gain and relative growth rate (RGR). The growth recorded/ day declined in infected larvae compared to uninfected ones from 8.2% during $1^{st}$ instar to 43.3% during $5^{th}$ instar. Food ingestion and digestion increased with advancement of the instar significantly irrespective of the status of the larvae but the relative consumption rate (RCR) declined. These parameters significantly declined in infected larvae (except food digested during $2^{nd}$ instar). The decline was more during $3^{rd}$ instar. In contrast, the approximate digestibility (AD %) was significantly higher in infected larvae than uninfected ones leaving the $1^{st}$ instar larvae unaffected. The efficiency of conversion of ingested food (ECI) and efficiency of conversion of digested food (ECD) did not change in a patterned way following the microsporidia (Nosema sp.) infection. The values of ECI significantly changed during $2^{nd}$, $3^{rd}$ and $5^{th}$ instars; while the change in ECD during $2^{nd}$, $4^{th}$ and $5^{th}$ were significant. During the entire larval life all the parameters tends to decline significantly following microsporidia infection but AD registered a significant increase. Nosema sp. spore concentration has increased 270.7 times during larval development in the course of experimentation.

Fast and dynamic biochemical, enzymatic and morphological changes occur during the so-called generative development and during the vegetative processes in seeds. The most characteristic biochemical and compositional changes of this period are the formation and decline of storage components or their precursors, the change of their degree in polymerization and an extensive change in water content. The aim of the present study was to detect the maturation processes in seed nondestructively and to verify the applicability of near infrared spectroscopic methods in the measurement of physiological, chemical and biochemical changes in wheat seed. The amount and variation of different water “species” has been changed intensively during maturation. Characteristic changes of three water absorption bands (1920, 1420 and 1150 nm) during maturation were analysed. It was concluded that the free/bound transition of water molecules could be followed sensitively in different region of NIR spectra. Kinetic changes of carbohydrate reserves were characteristic during maturation. An intensive formation and decline of carbohydrate reserves were observed during early stage of maturation (0 -13 days, high energy demand). An accelerated formation of storage carbohydrates (starch) was detected in the second phase of maturation. Five characteristic absorption bands were analysed which were sensitive indicators the changes of carbohydrates occurred during maturation. Precursors of protein synthesis and the synthesis of reserve proteins and their kinetic changes during maturation were followed from NIR spectra qualitative and qualitatively. Dynamic formation of amino acids and the changes of N forms were detected by spectroscopic, chromatographic and by capillary electrophoresis methods. Calibration equations were developed and validated in order to measure the optimal maturation time protein and moisture content of developing wheat seeds. The spectroscopic methods are offering chance and measurement potential in order to detect fine details of physiological processes. The spectra have many hidden details, which can help to understand the biochemical background of processes.

The objective of the study is to review trends of clothing export in important countries of the world and thus to know the present stage of clothing export in Korea. For the purpose, changes of export amount, competitiveness and product life cycle were analysed in the countries from the 1960's to the 1990's. The results are as following: First, on the aspect of export amount, industrialized countries lost the lead to newly industrializing countries from the 1960's. Developing countries, as China, win the lead. Second, on the competitiveness aspect, industrialized countries lost competitiveness to newly industrializing countries before the 1960's. And newly industrializing countries were outpaced by China in the export competitiveness from the early 1990's. Third, on the aspect of product life cycle, industrialized countries go first through each period of product life cycle, introduction, growth, maturity and decline, and they all, excluding Japan, sustained period of Maturity for a long time. newly industrializing countries and developing countries go orderly through each period of product life cycle after industrialized countries. As to Korea, duration of each period was short. Specially characteristics of decline period appeared partly in the early 1990's. From the results, the theory of product life cycle, helping to explain changes in production and trade in new product lines, estimated to applicable to clothing export. The phenomena, Italy, Hong Kong and America sustain high competitiveness in the world clothing market for a long time, is needed to be studied carefully. The study about strong points in their clothing industries and competitiveness drive program be to influence Korean export policy in the future.

Purpose : This study was conducted to assess the status of sarcopenia and locomotive syndrome in the Korean elderly population over 65 years of age by applying the recently updated screening tool for diagnostic evaluation of sarcopenia and locomotive syndrome. Methods : Sarcopenia and locomotive syndrome (LS) were diagnosed and evaluated in 210 Korean elderly people over 65 years of age. There were 36 patients in the "sarcopenia group", 164 in the "locomotive syndrome group", and 10 in the "normal group". The collected data were analyzed using the chi-square and Kruskal-Wallis tests. Results : The diagnostic evaluation of sarcopenia and LS showed the presence of sarcopenia in 9.05 % of males and 8.10% females among the Korean elderly population over 65 years of age. Prevalence of stage 1 locomotive syndrome (LS 1) was 95.24 %; stage 2, (LS 2) 36.19 %; and stage 3 (LS 3), 16.19 % among the study population. Both the sarcopenia diagnostic indicator and the LS evaluation indicators showed significant differences between the three groups. All the subjects in the sarcopenia group had LS; further, on comparison of the detailed composition ratio of each patient with LS, the prevalence of LS in the sarcopenia group was found to be: LS 1 41.67 %, LS 2 41.67 %, and LS 3 16.67 %, whereas in the LS group, it was found to be: LS 1 66.46 %, LS 2 16.46 %, and LS 3 17.07 %. The difference between the two groups was statistically significant. Conclusion : It was confirmed that sarcopenia is correlated with LS incidence. This suggests that the evaluation of motor LS can be used as a tool for the early diagnosis and prevention of sarcopenia in cases of functional decline due to aging in the elderly population.

관광지는 관광객에 의하여 이용이 지속될 때 관광목적지로서 그 생명력과 가치를 유지할 수 있으며, 그렇지 못할 경우 그 관광지는 곧 쇠퇴해 버리게 된다. 따라서 본 연구는 버틀러에 의해 제시된 관광목적지 수명주기이론을 바탕으로 한국에 분포하는 온천관광지 중 현재 이용중에 있는 46개 온천지구를 대상으로 수명주기 단계와 분포특성 및 이용객의 행태를 분석하여 관광목적지가 쇠퇴하지 않고 더욱 활성화하는 방안을 모색하고자 하였다. 분석대상으로 삼은 46개 온천지구 중 개발단계가 29개지구로 가장 많은 비중을 차지하고 있으며 성장단계 4개지구, 성숙단계 5개지구, 침체 및 쇠퇴단계 5개지구, 재활단계 3개지구로 나타났다. 이러한 수명주기에 영향을 미치는 분포특성 및 이용객의 행태를 분석한 결과 지형적 위치, 접근도에 의한 분포특성이 수명주기에 많은 영향을 미치는 것으로 나타났으며, 관광객들의 관광행태가 단일목적의 관장에서 다목적 관광으로 전환되고 있는 것으로 나타났다. 따라서 온천관장저의 활성화 방안으로는 온천지구의 확대지정과 온천수 보존, 장기체류형 관광지로의 복합개발, 도로망의 확충, 주변관광자원의 활용, 공동급수의 시행, 관광특구의 지정 등 관광객을 견인할 수 있는 새로운 관광매력물을 꾸준히 개발해야 할 것이다.

이 연구는 젊은 연령집단의 선별적 이동 및 세대에 걸쳐 진행되는 단계적 이동이 농촌과 도시의 출산력 변화와 지역의 인구성장에 파급되는 과정을 시계열적으로 분석하는 것이 목적이며, 전라북도 14개 시군이 사례지역이다. 분석에 활용된 자료는 1970 1990 2010년 20-34세 연령집단의 지역 간 인구이동 O-D 행렬과 같은 기간의 20-34세 연령집단과 가임 여성인구 분포 및 출생 사망의 동태자료이다. 분석 결과, 첫째 각 시점의 젊은 연령집단은 큰 규모로 출생지에서 이출하는 선별적 이동을 했다. 둘째 세대별로는 앞선 세대는 과거 전라북도 농촌에서 도시로, 뒤따르는 세대는 현재 전라북도 도시들에서 수도권으로 이동하는 단계적 이동이 존재했다. 셋째 젊은 연령집단의 선별적 이출은 출산 가임인구 축소, 저출산과 고령화 그리고 자연적 인구감소라는 과정을 수반되는데, 단계적 이동에 따라 과거 농촌에서 이러한 과정이 진행되었고, 현재는 전라북도 도시지역에서도 진행되고 있다. 실제로 전라북도 대부분 군 지역은 1980년대 후반부터 연간 사망자수가 출생아수를 상회하는 자연적 인구감소가 나타났고, 2000년대 초반에는 도시 지역에서도 이 같은 현상이 확인된다. 따라서 단계적 이동은 비수도권 중소도시 인구성장을 결정짓는 주요한 원인이며, 결과적으로 정주계층을 따라 단계적 과소화로 이어지고 있다.
