  • Diabetes mellitus is associated with a wide range of pathophysiological in the kidney. This study was designed to examine the effects of high glucose concentration on IGF-I binding and glucose transporters in renal proximal tubule cells. The results were as follows : The binding of $^{125}I-IGF-I$ reached the peak at the 30 minutes and gradually decreased by the time dependent manner. The binding of $^{125}I-IGF-I$ was inhibited by the unlabelled IGF-I($10^{-14}{\sim}10^{-8}M$) in a concentration dependent manner. The relative affinity of IGF-I receptor for IGF-I, IGF-II and insulin exhibited typical type 1 binding(IGF-I > insulin > IGF-II). However IGF-II did not compete for the cultured cell membrane $^{125}I-IGF-I$ binding site at $10^{-14}{\sim}10^{-8}M$. Under optimal conditions, IGF-I binding to the membranes from 5mM and 20mM glucose treated cells was analyzed. It was found that 20mM glucose treated cells exhibited higher binding activity for IGF-I. In order to further substantiate this increase in IGF-I binding sites, we performed affinity-labelling studies. The cross-linked cell membrane subjected to SDS-PAGE; labelled material was detected by autoradiography. 20mM glucose treated cells exhibited higher levels. The initial rate of $methyl-{\alpha}-D-glucopyranoside({\alpha}-MG)$ uptake was significantly lower($74.41{\pm}6.71%$) in monolayers treated with 20mM glucose than those of 5mM glucose. However, 3-O-methyl-D-glucose(3-O-MG) uptake was not affected by glucose concentration in culture media. IGF-I significantly increased ${\alpha}-MG$ uptake in both 5mM and 20mM glucose treated cells. However, 3-O-MG uptake was not affected by IGF-I in both conditions. In conclusion, 20mM glucose increased binding sites of $^{125}I-IGF-I$, inhibited Na/glucose cotransporter activity. But 20mM glucose did not change facilitated glucose transporter.

  • This study was conducted to identify the factors predicting binge drinking in men and women in Korea based on the results of the 7th year 3rd National Health and Nutrition Survey. The study data used the demographic and health-related characteristics and drinking characteristics of the National Health and Nutrition Survey, and were analyzed by cross-sample analysis and logistic regression analysis. As a result of the study, age (M:p=.003, F:p<.001), drinking frequency for one year (M:p<.001, F:p<.001), amount of alcohol consumed at a time (M:p<.001) 001, F:p<.001), family/doctor's recommendation for moderation (M:p<.001, F:p<.001), stress (M:p=.025, F:p<.001), Smoking (M:p<.001, F:p<.001) were predictors for binge drinking in both men and women. In addition, education level(p=.030) and economic activity status(p=.018) for men, income level(p<.001) and marital status(p=.020) for women were identified as predictors of binge drinking, and variables explained 72.4%(p < .001) and 74.5%(p < .001) of adult male and female binge drinking. This study is meaningful in that it provided basic data on the establishment of a gender-specific binge drinking prevention policy and the restructuring of drinking culture by clarifying that the risk factors of binge drinking in Korean adults differ by gender.

  • The number of single households in Korea has been sharply increasing due to dissolution of the family community and changes in housing culture. Therefore, there is a need to develop a plan for diagnosis of changes in the housing market in response to a rapid increase of single household to suggest a proper direction of housing policy. This study was conducted to clarify the factors influencing housing occupancy type targeting a single adult household. To accomplish this, a cross-sectional analysis was conducted using the multi-nominal logit model and the Korea Welfare Panel's 9th survey materials. Occupants of ingle households in their 20s and 30s were found to be much poorer than those in their 40s, or older. Additionally, single household in their 20s and 30s, the characteristic of a household having an influence on the choice of housing occupancy type showed a result in a different direction even from the same household characteristic of those in their 40s, or older. Finally, the characteristics of occupants of single households in their 20s and 30s showed room for improvement through public support. Overall, the results of this study implied the need to inquire into the government's periodic support in more diverse ways.

  • Growth hormone releasing hormone (GHRH), the major hypothalamic stimulus of GH secretion from the anterior pituitary gland, has been found to be present in several extrahypothalamic sites including placenta testis, ovary and anterior pituitary gland. The present study was performed to elucidate the role of pituitary GHRH on proliferation of cells derived from rat anterior pituitary gland. The GHRH content of pituitary tissue, cultured pituitary cells, and the conditioned media was evaluated by radioimmunoassay (RIA). Primary cultures of pituitary cells derived from adult rats were prepared by enzymatic dispersion. Significant amounts of GHRH-like molecules were detected in both pituitary tissue and cell cultures by GHRH RIA. Competition curves with increasing amounts of tissue extracts and conditioned media were parallel with those of standard peptide, indicating that the pituitary GHRH-like material is similar to authentic GHRH. To analyze specific cell types responsible for producing GHRH in anteroior pituitary, cell fractionation technique combined with GHRH RIA was performed. In cell fractionation experiment, the highest level of GHRH content was found in gonadotrope enriched-fraction and followed by somatotrope-, lactotrope- and thyrotrope-fraction. Treatment of pituitary cells with GHRH resulted in a dose-dependent increase in [$^3$H] thymidine incorporation. The mitogenic effect of GHRH could be mediated by typical oncogenic activation since the GHRH induced transient increase in c-fos mRNA levels with peak response at 30 minutes. The present study demonstrated that i) the pituitary GHRH expressed in the rat anterior pituitary gland can be secreted, ii) among the various cell types, gonadotropes and somatotorpes are the major GHRH source, and iii) the GHRH treatment increased the [$^3$H] thymidine incorporation and c-fos transcriptional activity in the pituitary cell culture. These findings suggested that GHRH could participated in the paracrine and/or autocrine regulation of cell proliferation, as well as promoting growth hormone secretion.

  • Loop-mediated isothermal amplification (LAMP) is an emerging detection technology for the amplification of DNA under isothermal conditions. The aim of this study was to develop a rapid and reliable LAMP technique for the detection of Cronobacter sakazakii in milk powder. In order to enhance the sensitivity and specificity, LAMP primers targeting outer membrane protein A (ompA) gene of C. sakazakii were designed using Explorer V4 software. Thirty seven C. sakazakii strains and 13 pathogenic microorganisms were used for comparative detection of C. sakazakii using polymerase chain reaction (PCR), real-time PCR, and LAMP. LAMP developed in this study could specifically detect C. sakazakii strains without cross-reactivity with other foodborne pathogens. LAMP products amplified from ompA gene of C. sakazakii were digested with with HhaI and NruI enzyme. The specificity of LAMP was confirmed by restriction fragment length polymorphism (RFLP) analysis. LAMP could detect C. sakazakii within 1 h without bacterial culture and its detection limit was as low as 1 CFU/mL C. sakazakii in milk. In the comparison of the sensitivity, LAMP showed 10,000- and 100-times higher detection limit than PCR or real-time PCR, respectively. Therefore, this study can conclude that LAMP is a rapid and reliable detection technique for C. sakazakii contaminated in powdered milk.

  • 'Gwanha' is new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar, which was released by Highland Agriculture Research Center, Rural Development Administration, in 2011. In 2007, this cultivar was originated from a cross between 'Sucambodiaberry' and 'Selva' that showed excellent ever-bearing characteristics including continuous pink flowering habit under long-day and high temperature condition. It was named 'Saebong No.4' after examining its characteristic and productivity in summer culture from 2009 to 2011. After characteristic and productivity test in 2011, 'Gwanha' was selected as an elite cultivar. The general characteristics of 'Gwanha' include spreading type, middle vigor, elliptic leaf, and long cluster in growth. The fruit shape is wedge, and the red fruit is edible and unique among the domestic ornamental strawberry cultivars. Flower color of 'Gwanha' is pink, and flower cluster is more appearance than 'Pinkpanda'. The average fruit weight of 'Gwanha' is about 7.8 g and the marketable yield is relatively low because of low marketable rate. It is resistant against fusarium wilt. 'Gwanha' is suitable for four season cultivation as an ornamental strawberry cultivar because it shows continuous flowering habit under long-day and high temperature condition.

  • This study sought to figure out women's functional status after childbirth under the Sanhujori. Functioal status was defined as the women's readiness to assume infant care responsibilities and resume her usual activities including household, social and community, self-care and occupational activity. A convenience sample of 211 women who are in the postpartal period of the range from 1 week to 3 months above and residing in Seoul. Korea was studied from January, 1997 to December, 1998 for two years. Mean age of respondents was 29.9 years and mean of the present postpartal period was 7.5 weeks. The present postpartal period was of 5-8 weeks 26.5%, 3-4weeks 26.1%, 9-12 week 23.7% and below 2 weeks 7.1%, 32.7% of women had a job and the mean period of return to job was 2.76 weeks. During Sanhujori the non professional care giver was family members from women's maiden home 73.5% and only 2% of husband. The period women needed for the recovery from now was 5.39 weeks and it means that women need 12.9weeks for recovery after childbirth. For the present subjective health status after childbirth, bad was 20.2%, good 18.3 and average 61.5% and for the recovery status, completely recovered 29.5%, slightly 61.8% and rarely 8.7%. The mean of functional status at the 7.5weeks was baby care activity 3.65, household 2.57, self-care 2.46, occupational 2.44 and social 1.53 in rank. Except baby care the functional status was generally low or very low. The related factors to the functional status were the period and subjective evaluation of Sanhujori women experienced, the present period of postpartum, and subjective feeling of recovery. This result strongly reflects the effects of Sanhujori culture and Sanhujori per se on women's postpartal life including functional status and reconfirmed the relationship between health status and the experience of Sanhujori after delivery as the previous findings from various study showed. It provides a challenge to the professional care givers to research further on the effects of Sanhujori on the health status, health recovery after abortion or delivery from the various aspects through the cross-sectional and longitudinal research for the refinement of the reality of Sanhujori not only as cultural phenomenon but as an inseparable factor influencing in women's postpartal healthy adaptation and for the appropriateness of intervention and quality of care for desirable health outcome.

  • In order to search for the reasonable planning directions for representing traditional landscape, this study conducted the comparative analysis of the designs on the panels and their constructions from both winners of "The Landscape Design Competitions for City Infrastructure of Minlak(2) District in Uijeongbu" and "The Design Competition for Dongtan(2) District Land Development Phase 1". The representing targets and views, the composition and placement of representing space, the design of representing facilities and landscape planting were examined based on the text, master plans, elevations and cross sections, diagrams, images, and perspective drawings proposed from the competition panels. Then, the landscape constructions were reviewed. The results are as follows: First, the types of the representing targets and views are the agricultural landscape, as the local landscape of target area, which are divided into the life space of a traditional village, the traditional water space, and the traditional culture. Second, as to the composition and placement of representing space, the traditional theme spaces are formulated considering the surrounding land use and the local cultural heritage. However, some spaces were changed to the exercise space or convenient facility spaces required in a neighborhood park. Third, in the case of the representing facilities, a round island in the square pond, a traditional pavilion and Hwagye(terraced flower bed) were made without the facilities designed creatively. Fourth, the application of traditional planting techniques was focused on planting trees in the village forest on an island in the square pond and on Hwagye. Fifth, the traditional representing work has gradually advanced with the selection of subject and experimental facility designs based on the professional references. Sixth, the choice of the realizable subject, the expertise for information analysis and the creative design of the traditional facility are required in the future.

  • The present article reviews recent arguments on the moral-conventional distinction in moral judgment and discusses the implications for moral psychology research. Traditional research on moral judgment has considered both the evaluation of transgressive actions of others and the categorization of the norms on the moral-conventional dimension. Kohlberg, Piaget, and Turiel (1983) regard moral principles to be clearly distinguished from social-conventional norms and suggested criteria for the moral-conventional distinction. They assume that the moral domain should be specifically related to the value of care and justice, and the judgment for the moral transgression should be universal and objective. The cognitive developmental approach or social domain theory, which has been generally accepted by moral psychology researchers, is recently being challenged. In this article, we introduce three different approaches that criticize the assumptions for the moral-conventional distinction, namely, moral sentimentalism, moral parochialism, and moral pluralism. Moral sentimentalism emphasizes the role of emotion in moral judgment and suggests that moral and conventional norms can be continuously distributed on an affective-nonaffective dimension. Moral parochialism, based on the evidence from anthropology and cross-cultural psychology, asserts that norm transgression can be the object of moral judgment only when the action is relevant to the survival and reproduction of a group and the individuals within the group; judgment for moral transgression can be as relative as that for conventional transgression. Moral pluralism suggests multiple moral intuitions that vary with culture and individual, and questions the assumption of the social domain theory that morality is confined to care and justice. These new perspectives imply that the moral-conventional distinction may not properly tap into the nature of moral judgment and that further research is needed.

  • Kyong-Eui Railway used to be one of the major cross-country railways connecting Busan and Shineuiju. Being the central axis of logistics and transportation in Korea, it also signifies a symbolic meaning of the people's desire for the unification of divided Korean peninsula. A steam locomotive that had stopped in Jangdan Station was bombed out during the Korean War. The locomotive has been neglected and covered with rust in DMZ over a half century, and now is becoming a historic reminder of divided Korea. The initial design approach was based on the three main perspectives of the relocation plan of the steam locomotive in Jangdan Station which is designated as the registered cultural asset no. 78: historical significance, role of a monumental space, and influence on and from the local culture and tourism. Three design subjects were especially highlighted which would represent the identity of the cultural asset, the stream locomotive. First, a vertical watching deck was installed to provide various view points toward the locomotive while ensuring the security of visitors as well as the cultural asset. Second, the Dokgae bride area has good design potentials being on the railway. However, the site is too narrow. Thus, a new ramp and a stairway were placed responding to the existing topography so that the pedestrian environment could be secured last, to respect the local context where the locomotive was originally located, mulberry trees in the locomotive were transplanted as well. Flowering plants were planted around the display area for better ventilation to minimize the negative impact on the locomotive.
