In a digital environment that is keep in change content from smart phones to tablet PC are a social network service is holding deep place in our lives. Social networking applications has building a network and communication with others than other application, it means that Social networking applications are sharing not only personal purpose in that trend of variety and competition of these social networks can be expected to trend and be developed thru analysis of user certification. this study of social network service application is proposed to developing of application thru analyze the two-effective application which is high ranked in google store. the theoretical foundation was set based on the seven elements of the social network service of the information structures designed by Jean Smith. This study proceeded analysis is for the functional elements of Facebook and Instagram, and the advantages and disadvantages through survey research. As a result of the empirical analysis to user of Instagram and face book of communication, identity, satisfaction for the group are equally. Instagram is about the presence, reputation, and Facebook has had a high level of satisfaction for each sharing and relationship. Facebook got high satisfaction from sharing features, but user feel of discomfort in the randomly showing advertising content. Instagram is not showing off advertise on common page of content, it is good point to be complementary to facebook. And, Instagram hashtag is good for convenience, but satisfaction is high with Facebook. in order to increase the satisfaction of Instagram, it is necessary to consider the main advantage of the communication and the functional aspects of the share from facebook.

Natural moisturizing factors (NMFs) are hydrophilic and water-soluble components in stratum corneum of the skin. NMFs absorb water from outer environment and enhance the water-holding capacity of stratum corneum and thereby, prevent the dryness and increase flexibility and plasticity of skin. NMFs are mainly composed of amino acids and their metabolites that are produced from the degradation of filaggrin. Here we established a simultaneous quantification method for 22 amino acids in tape-stripped stratum corneum samples using UPLC-PDA. With this method, we analyzed amino acid contents from tape-stripped stratum corneum samples of forearm and forehead regions from 15 healthy volunteers. Amino acid contents of inner (or upper) region were higher than outer (or lower) region of stratum corneum. Amino acid contents of stratum corneum of forearm were higher by 1.5 fold than forehead region. Of note, total amino acid contents were significantly and inversely correlated with trans-epidermal water loss (TEWL), an index for skin barrier function. Especially, Ser, Glu, Gly, Ala and Thr were determined to positively affect skin mositurizing activities. In conclusion, we could demonstrate that amino acid contents of stratum corneum are closely linked with skin barrier and moisturizing function, providing an important and fundamental methodology for the study of amino acids in skin physiology.

This study was carried out to obtain the effects of soil environment and characteristics on the growth and yield of young rice seedling. Twenty four rice fields were selected among the labor saving mechanization complex, and the growth statu s and various soil characteristics were investigated The young rice seedling planted soils were located at the range of elevation 5m to 210m, and the average water holding days was 5.1 days, and drainage class were mainly moderately well to imperfectly. The plant height on 30th day after machine transplanting were higher and the tiller numbers were smaller at the higher clay contents at moderately well and imperfectly drained soils. In case of sandy loam soils, the better the drainage class, the higher plant and more tillers. Soil hardness was lower in sandy loam, and the bulk densities of loam, silty clay loam and poorly drained soils were lower than the other fields. There were not differences of soil chemical properties between the soil textural groups but organic matter content were higher in poorly drained soils. The rice yields of young seedling planted fields were negatively correlated to soil bulk density and highly significantly correlated to the exchangeable calcium contents of the soils. The average yield of young rice seedlings was 487kg/10a, 2.5% higher than semi-adult rice seedling of 475kg/10a.

Zinc oxide (ZnO) and reduced graphite oxide (rGO) composites were synthesized and tested as adsorbents for the hydrogen sulfide ($H_2S$) adsorption at mid-to-high (300 to $500^{\circ}C$) temperatures. In order to investigate the critical roles of oxygen containing functional groups, such as hydroxyl, epoxy and carboxyl groups, attached on rGO surface for the $H_2S$ adsorption, various characterization methods (TGA, XRD, FT-IR, SEM and XPS) were conducted. For the reduction process for graphite oxide (GO) to rGO, a microwave irradiation method was used, and it provided a mild reduction environment which can remain substantial amount of oxygen functional groups on rGO surface. Those functional groups were anchoring and holding nano-sized ZnO onto the 2D rGO surface; and it prevented the aggregation effect on the ZnO particles even at high temperature ranges. Therefore, the $H_2S$ adsorption capacity had been increased about 3.5 times than the pure ZnO.

Maternity nurses' roles are to find out women's various responses related to the health problems during pregnancy, to intervene adequate nursing and supports, and to help them adapt satisfactorily to new situation, such as hospitalization. The purposes of this study are : firstly, to inquire about women's emotional status, feeling of discomfort, and the nursing need during hospitalization because of discomfort, and the nursing needs during hospitalization because of the possibility of abortion by threatened and habitual abortion : secondly, to provide fundamental data for developing adequate nursing intervention and improving hospital management. The subjects of this study were 62 women who were hospitalized, visited out-patient clinic for follow-up, and stayed at home after discharge since August, 1993 from one hospital located in Seoul, from March 23 to April 13, 1994. The questionnaire was consisted of 21 items of emotion(Reliability Cronbach's alpa, .77), 19 items of feeling of discomfort(.79), and 21 items of nursing needs (.89), and nurses' performance according to nursing needs,(.90). These were measured by using Likert Scale and analyzed by using SPSS / $PC^+$ with the descriptive statistics, $X^2$-test, and ANOVA. Research findings are as follows : 1) The subjects' average age, hospitalized days, and gestational age are 32.2, 15.7, 12.9 by respectively. 2) 88.7% of the subjects are getting antepatal care, 66.1% are experiencing 1.75 times of spontaneous abortion, and 82.3% are nuclear family. 3) The Emotions were mainly comprized negative and subjective state of minds such as uneasiness, anxiety, and discomfort. The domains of emotions were related to 'fetus', 'herself', 'hospitalization', and 'husband's 'families', in rank. The highest scored item was "I, above anyone else, am mostly stressed from abortion." 4) The feelings of discomforts were firstly related to 'personal discomfort arising from absolute bed rest', 'meals provided', Usage of hospital, perse', 'health team', in rank. 5) The nursing needs frequently pointed out were 'Nurses kindly explain of me the purpose, method, and results of the lab. test', 'Nurses sincerely pay attention to my word in communication'. The least nursing needs were 'Nurses observe my feces and whether I have constipation or not'. 'When I can't move, nurses help me by holding my arms or pulling my bed'. 6) The highest performed items were 'Nurses observe whether I bleed or not', and 'Nurses give me drug with exact dose in time'. The least performed items was about hospital environment, such as 'Temperature, ventilation & humidity in the room should be controlled'. 7) Besides religion that is related to nursing need with statistically significant difference, none of general characteristics were related to emotion, feeling of discomfort, and nursing needs.

In recent years, IT advancement has brought out the new Internet communication environment such as online social network services, where people are connected in global network without temporal and spatial limitation. The popular use of online social network helps people share their experience and preference for specific products and services, thus holding large potential to significantly affect firms' business performance through Word-of-Mouth (WOM). This study examines the role of online social network in raising WOM effect on the movie industry by comparing with the similar role of Internet portal, another major online communication channel. Analyzing 109 movies and data from both Twitter and Naver movie, we found that significant WOM effect exists simultaneously in both Twitter and Naver movie. However, we also found that different figures of online viral effects exist depending on the popularity of movies. In the hit movie group, before the movie release, the WOM effect occurs only in Twitter while the WOM effect arises in both Twitter and Naver movie at the same time after the movie release. In the less-popular (or niche) movie group, the WOM effect occurs in both Twitter and Naver movie only before the movie release. Our findings not only deepen theoretical insights into different roles of the two online communication channels in provoking the WOM effect on entertainment products but also provide practitioners with incentive to utilize SNS as strategic marketing platform to enhance their brand reputations.
