'Tight junctions (TJ)' have recently been identified in the granular cell layer of the human epidermis, where they contribute to the normal adhesion between keratinocytes and to the physiologic barrier function of the epidermis. Among the TJ proteins in the epidermis, occludin is an important transmembrane protein, which is considered as a major component. The purpose of this study is to investigate whether regional variation exists in the expression of the tight junction protein occludin in normal human epidermis. Indirect immunofluorescence staining for occludin was performed with specimens taken from different areas of normal skin (4 from each of 7 different anatomical sites, including the scalp, face, posterior neck, upper arm, abdomen, lower back, and inner thigh). The degrees of the expression-intensity in each specimen were estimated with the reciprocals of positive end-point titer of occludin in an indirect immunofluorescence study. The highest degree expression-intensity of the TJ protein occludin among the different areas of normal epidermis was observed on the face and abdomen with a titer of 600 (p=0.001). The lowest intensity of expression of occludin was seen in the epidermis from the upper arm. Skin specimens from the scalp, neck, back, and leg demonstrated intermediate degrees of the expression in intensity. The expression of occludin in the skin samples obtained from different locations of the body showed a statistically significant variation. This suggests that there is a certain degree of regional variation in the expression-intensity of TJ protein 'occludin' in the human epidermis.

도로소음은 다양한 소음원에 의해 발생하며, 도로를 이용하는 사람과 도로 주변사람에게 큰 불편을 초래한다. 보다 쾌적한 환경을 원하는 현대인에게 있어 도로 소음의 경감은 중요한 환경 공해로 작용한다. 도로 소음을 줄이기 위해서는 여러 가지 방법이 있을 수 있으며, 이 중 도로 포장의 개선을 통해 도로 소음을 경감할 수 있으며, 이와 같은 포장을 저소음 포장이라고 한다. 저소음 포장은 주행하는 차량의 타이어와 노면이 마찰하면서 발생하는 소음을 최소화하기 위한 것으로 소음 발생의 메커니즘을 바탕으로 하고 있다. 저소음 포장중 가장 널리 사용되고 있는 방법은 공극을 늘리는 것이다. 약 20%의 공극은 타이어와 노면 사이의 에어펌핑음을 최소화 하며, 소리를 흡수하는 역할로 약 3dB의 소음 가소 효과가 있는 것으로 알려져 있다. 소음을 감소시키는 또 하나의 방법은 노면의 표면 조직을 매끈하게 하여 타이어와 노면의 충격음을 줄이는 방법이다. 노면의 평탄성을 개선하기 위해 포장에 사용되는 골재의 최대크기를 줄이는 소입경 포장을 소음 가소의 목적으로 유럽 등지에서 많이 사용되고 있다. 본 연구에서는 이와 같은 저소음 기능을 위해 공극률을 크게 하고 소입경 골재를 사용하는 소입경 저소음 포장의 현장 적용을 위한 배합 설계를 수행하였다. 소입경 저소음 포장의 최대 골재 크기는 현장 적용성과 경제성을 고려하여 10mm 골재를 사용하였으며, 수도권에서 입수한 4곳의 산지 골재를 분석하여 골재 합성 입도를 산정하였다. 10mm 저소음 포장의 골재 입도 범위는 공극률 15~18%를 목표로 하며, 이를 만족하기 위하여 배합 설계를 수행한 결과 5mm 통과 중량 백분율이 약 30%로 하는 개립도가 적당한 것으로 나타났다. 공극이 증가함에 따라 포장의 내구성 향상을 위해 사용된 고점도 바인더는 아스팔트 혼합물의 생산 및 시공온도를 증가시키게 된다. 또한 굵은골재의 비율이 높은 개립도 아스팔트 혼합물의 경우 운반과정과 포설 과정에서 온도가 빨리 떨어지는 단점이 있다. 이를 극복하기 위하여 중온 첨가제의 사용을 통해 생산 및 다짐온도를 낮추고자 하였다. 소입경 저소음 포장의 배합설계 과정은 배수성 포장의 배합설계 과정과 유사하나, 칸타브로 손실률과 흐름실험의 변곡점을 기준으로 할 경우, 칸타브로 손실률과 흐름 손실률이 매우 작아 변곡점을 판단하기 어렵기 때문에 칸타브로 손실률과 흐름 손실률의 기준 만족 여부로 판별하고, 최적 아스팔트 함량은 공극률을 기준으로 산정하는 것이 바람직할 것으로 판단된다. 중온 첨가제를 사용할 경우는 중온 첨가제로 인한 점도의 변화를 감안하여 혼합 및 다짐 온도를 결정하고 배합 설계를 수행하며, 중온 첨가제의 특성과 양에 따라 최적 아스팔트 함량이 변화하게 된다.

The world's best level of ICT(Information, Communication and Technology) infrastructure has experienced the world's worst level of ICT accident in Korea. The number of major accidents of privacy invasion has been three times larger than the total number of Internet user of Korea. The cause of the severe accident was due to big data environment. As a result, big data environment has become an important policy agenda. This paper has conducted analyzing the accident case of data spill to study policy issues for ICT security from a social science perspective focusing on risk. The results from case analysis are as follows. First, ICT risk can be categorized 'severe, strong, intensive and individual'from the level of both probability and impact. Second, strategy of risk management can be designated 'avoid, transfer, mitigate, accept' by understanding their own culture type of relative group such as 'hierarchy, egalitarianism, fatalism and individualism'. Third, personal data has contained characteristics of big data such like 'volume, velocity, variety' for each risk situation. Therefore, government needs to establish a standing organization responsible for ICT risk policy and management in a new big data era. And the policy for ICT risk management needs to balance in considering 'technology, norms, laws, and market'in big data era.

As safety Issue becomes one of the hot topics, practical researches and feasible policies are in needs not only for central government but also local officers. The previous studies focused on organizational or institutional approaches and on functional efficiencies, especially how to integrate disaster data at every stage of disaster from preparedness to recovery. Physical and social environments differ from among others, top-down disaster management plan cannot work, and therefore more practical statistics and survey is required to prepare the safety management plan for local government. We aim to suggest a safety environment survey framework and to apply it to two guns (Muan and Goheung). We considered main factors of the framework based on legal requirement for safety index and four stages of disaster progress. Two guns are located in remote area and have a population who are weak to disaster. Action items were drawn from the survey and analysis from the framework respectively. We expect this framework to be expanded to include more urbanized and complex areas.

다품종 소량 생산에 적합하고 소비자들에게 신선한 제품을 제공할 수 있을 뿐 아니라 노동력을 절감할 수 있는 등 여러 가지 이점으로 인해 냉동 반죽의 사용이 증가되고 있다. 하지만 냉동 중에 효모와 글루텐이 손상되어 냉동 반죽으로 제조한 빵은 부피가 작고 노화가 빠르게 진행되는 단점을 보인다. 따라서 이러한 단점을 보완하기 위한 다양한 방법이 요구되며 그 중 하나로 보수성과 빙결정 생성 억제능력을 가지는 다당류와 단백질을 첨가하여 그 효과를 살펴보고자 한다. 사용된 첨가물은 다당류로 carrageenan(C)과 sodium alginate(A), 단백질로 whey(W)와 casein(C)이었는데 다당류와 단백질을 각각 1:1로 혼합해서 첨가하였다. 정해진 배합비 대로 반죽을 하고 급속 동결시킨 후 일주일 동안 저장하면서 5차례 냉동-해동을 반복한 반죽을 시료로 사용하였다. 냉동 반죽을 해동시킨 후 발효정도를 측정하기 위해 발효팽창력을 측정하였다. 냉동 반죽으로 식빵을 제조하고 빵의 비용적, 색도를 측정하였고 관능적 특성으로 crumb부분의 색, 대칭성, 균일성, crust의 색, 터짐성을 측정하고 맛, 향, 조직감, 전반적 기호도를 측정하여 냉동 반죽의 제빵 특성을 조사하였다. 또한 3일간 냉장저장하면서 texture와 수분함량을 측정하여 시료에 따른 노화도를 측정하였다. 냉동생지의 발효팽창력에서 WK 첨가구가 23.5, WA 첨가구가 24.75로 CK, CA 첨가구에 비해 3∼4정도 큰 값을 보였으며, 모든 첨가구가 대조구 18.5보다 큰 발효력을 보였다. 식빵의 비용적은 WK 첨가구 3.539, WA 첨가구 3.506, CA 첨가구 3.377, CK 첨가구 3.247, 대조구 3.064 순으로 큰 값을 보였는데 비용적은 발효력과 정의 관계를 보임을 알 수 있었다. 제조당일과 냉장고에 3일간 저장한 빵의 수분함량, 경도를 비교해 보면 수분함량 의 경우, 대조구가 43.63%에서 42.31%로 1.32% 줄어 가장 큰 감소율을 보였으면 CK 첨가구가 45.12% 에서 44.30%로 0.815% 줄어 가장 작은 감소율을 보였다. 그 외 첨가구의 경우 변화율은 1.26∼l.3%로 유의적인 차이를 보이지 않았다. 대체적으로 수분함량의 감소가 대조구보다 첨가구에서 작은 것은 첨가제의 보수성에 기인하는 것으로 사료된다. 경도의 경우, CK 첨가구가 0.244kg에서 0.558kg로 0.334 kg증가하였으며 대조구는 0.212kg에서 0.530kg으로 0.318kg증가하여 다른 첨가구에 비해 높은 경도를 나타내었다. CK 첨가구의 경우, 저장 중 수분함량의 감소율이 가장 작은 것과 달리 경도에 있어서 가장 큰 값과 증가 경향을 나타냈는데 이는 CK 첨가구의 빵이 다른 첨가구의 빵의 비용적보다 작은 것과 관련이 있다고 판단된다. 빵 내부의 색도를 측정했을 때 명도 L값은 CA 첨가구가 76.162로 가장 컸고 WA 첨가구가 12.822로 가장 작은 값을 나타냈으며 다른 첨가구와 대조구의 L값은 73∼74의 범위로 유의적인 차이가 없었다. 적색도 a값과 황색도 b값에서 모든 첨가구가 대조구에 비해 낮은 값을 보였다. 색도의 결과와 관능적 특성 중 내부 색의 선호도를 비교해 보면 큰 차이는 없지만 대조구보다 높은 명도값과 낮은 적·황색도값을 가지는 첨가구의 선호도가조금 높음이 확인되었다. 그 외 관능적 특성들에서도 대조구와 첨가구의 빵의 선호도 차이는 크게 군별되지 않았다. 결론적으로 실험에 사용된 첨가제는 냉동변성을 억제시켜 반죽의 발효력과 빵의 비용적을 높이고 또한 노화도를 늦추는등 냉동반죽의 제빵성을 높이는데 기여할 수 있을 것으로 생각된다.

This study was conducted to investigate the quality characteristics of dumpling shells with added Pleurotus eryngii powder (PP) (2%, 4%, 6%). The weight after cooking and volume of the dumpling shells increased with the addition of PP. The water absorption of the dumpling shells was not significantly different by the addition of PP. Turbidity after cooking increased and hardness decreased by adding PP. The L value after cooking decreased with the addition of PP, and the b value was highest when the content of PP was 6%. Adhesiveness increased by adding PP and springiness decreased when PP content was above 4%. Chewiness and gumminess decreased by adding the powder. There were no differences among the control, 2%, and 4% samples in cohesiveness values, but cohesiveness significantly decreased with the addition of 6% of powder. Color characteristics showed low values when PP was added at more than 6% according to sensory characteristics tests. No significant differences were found in flavor, taste, smoothness, moisture, or adhesiveness of the dumpling shells after cooking according to additions of PP. Chewiness was higher by adding PP compared to the control, but no significant differences were found by additions of PP.

SNS allowed users to serve not only as the content and message producer but as the consumer, with development into various types of SNS platforms. Instead of a traditional media structure of media-to-many and unspecified users, it also made it possible to achieve one-to-one or one-to-many interactions, regardless of time and space, through SNS platforms. Moreover, according to development of digital communication technology, IT, media contents and communication network have been mutually connected, though they were once separate. The changes in communication environments have caused rapid disorganization and reorganization in popular culture led by specific expert groups. Such trend has a greater influence on marketing strategies of enterprises. In other words, it will lead them to mostly introduce new information technologies, based on consumer market, and to strategically participate in SNS for promotion and marketing for their products and brands. Likewise, SNS has currently appeared as the main media affecting consumers' behaviors. In consideration of the importance of SNS features, which can stimulate responses of other users, analysis of main features affecting SNS user acceptance decision is required, as well as its utilization strategies. Accordingly, this study conducted division of SNS features into openness, quickness, interactiveness and economical efficiency to derive strategies for increasing the usage frequency of SNS and ultimately maximizing the expectation effect, in addition to an empirical analysis of effects of SNS features on usefulness, easiness and pleasure perceived in SNS, and SNS user intention.

For a social venture in early stage, it is very difficult to set up a strategy as it has to pursue two contradictory goals; economic value and social value. The platform strategy can be good alternative solution for social ventures as it seeks building-up connections with other businesses to co-create value despite of limited resources. A Korean social venture, JUMP! which adopted platform strategy in the early stage, and successfully applied 4 key factors of platform strategy; core competency, value creation ability, efficiency and network effect, has been able to develop sustainable growth for itself and induce innovation and growth among the participants within the platform. This study was intended to research effect of adoption and successful application of platform strategy for social ventures in the early stage of start-up and draw conclusion through case study that platform strategy works for sustainable growth of social ventures.
