In this paper, we developed contact type temperature sensor with single crystal silicon strip thermopile. This sensor consists of 15 p-type single crystal silicon strips, 17 n-types and contact electrodes on silicon dioxide silicon membrane. The result of electromotive force measuring showed very good characteristic as $15.18mV/^{\circ}C$ when temperature difference between the two ends of the thermopile occurs by applying thermal contact on the thermopile which was fabricated with silicon strip of $200{\mu}m$ length, $20{\mu}m$ width, $1{\mu}m$ thickness.

This study introduces the navigational environment database(DB) compiling water depth, sediment type and marine managed areas (MMAs) in coastal waters of South Korea. The water depth and sediment data were constructed by combining their sparse points of electronic navigation chart and survey data with high spatial resolution using the inverse distance weighting and natural neighbor interpolation method included in ArcGIS. The MMAs were integrated based on all shapefiles provided by several government agencies using ArcGIS because the areas should be used in an emergency case of ship. To test the validity of the constructed DB, we conducted a test application for grounding and anchoring zones using a ship accident case. The result revealed each area of possible grounding candidates and anchorages is calculated and displayed properly, excluding obstacle places.

Although companies perform societal marketing activities across different cultural regions, previous research was predominantly centered on a specific cultural region-the West. To address this limitation in the literature, the current research examines societal marketing in the Chinese market considering cultural characteristics. China has become the largest market in the world with great potential growth for its vast consumer base. Since there is heterogeneity among regions in China, it is imperative to divide China into several markets for better understanding. Thus, this study investigates different responses of Chinese regional (coastal vs. inland) consumers toward Cause-related Marketing (CM). Our findings reveal that Chinese consumers, in general, prefer utilitarian CM products compared to hedonic CM products, which is the opposite result of findings of the previous research. Further, this was truer for consumers in inland regions, while coastal consumers did not display any preference by product type. The academic and practical implications, limitations, and directions for future research are discussed.

We analyzed the hair microstructure of Korean small terrestrial mammals, such as Rodentia and Lagomorpha, to classify the characteristics of hair morphology. Micromys minutus showed a unicellular irregular type of medulla structures; on the other hand, the other mammals showed multicellular structures. Regarding the cuticular scale structures, the Rodentia species exhibited a narrow and broad diamond petal type, while the Lagomorpha species exhibited an elongated petal type. Interestingly, the hair cross-sections showed quite unique characteristics. We constructed hair identification keys to distinguish species with a single hair. The dichotomous key of Rodentia and Lagomorpha can be used for their behavioral ecology and dietary analysis of upper predators to serve as the basis for ecological research.

To understand the hyrogeochemical variation of bedrock aquifer during underground space construction, various graphical methods including multiple-component plots and chemical trends were used to estimate the mixing rate between seawater and freshwater and to investigate the evolution of water quality. The water chemistry and mixing rate between fresh and sea waters, which are generally localized in the construction area (MW-7, in land), shows typical characteristics of freshwater that doesn’t affect its validity as seawater intrusion. Especially, the water chemistry of a MW-4 (coastline) was classified as Na-Cl type, Na-HCO₃ type, and Ca-Cl type due to the influence of the seawater intrusion. And hydrogeochemical and isotopic data show that local freshwater is subjected to geochemical processes, such as reverse ion-exchange. Throughout the Chadha’s diagrams, four different case histories with the temporal and spatial variation of groundwaters in the study area were proposed, which is recommended to interpret the hydrogeochemical reactions effectively.

Type 1 diabetes mellitus (T1DM) is an autoimmune disease characterized by extreme insulin deficiency due to an overall reduction in the mass of functional pancreatic ${\beta}$-cells. Several animal models have been used to study T1DM. Amongst these, the mini-pig seems to be the most ideal model for diabetes research, owing to similarities with humans in anatomy and physiology. The purpose of this study was to analyze differentially expressed pancreatic proteins in a streptozotocin (STZ)-induced mini-pig T1DM model. Pancreas proteins from mini-pigs treated with STZ were separated by two-dimensional gel electrophoresis, and 11 protein spots were found to be altered significantly when compared with control mini-pigs. The data in this study utilizing proteomic analysis provide a valuable resource for the further understanding of the T1DM pathomechanism.

Recently, a problem related to the thermal management in portable electronic and telecommunication devices is becoming issued. That is due to the trend of a slimness of the devices, so it is not easy to find the optimal thermal management solution for the devices. From now on, a pressed circular type cooling device has been mainly used, however the cooling device with thin thickness is becoming needed by the inner space constraint of the applications. In the present study, the silicon flat plate type cooling device with the separated vapor and liquid flow path was designed and fabricated. The normal isothermal characteristics created by vapor-liquid phase change was confirmed through the experimental study. The cooling device with 70 mm of total length showed 6.8 W of the heat transfer rate within the range of $4{\sim}5^{\circ}C/W$ of thermal resistance. In the future, it will be possible to develop the commercialized cooling device by revising the fabrication process and enhancing the thermal performance of the silicon and glass cooling device.

This research is about Department of Emergency medical services students' cognition type of female 119 paramedics. The purpose of this research is to understand department of emergency medical servises students' cognition of female 119 paramedics and identify characteristics classified by types. To this end, applying Q-method, this research objectively analyzes 72 department of emergency medical services students' reaction who complete the field training about ambulance about female 119 paramedics. The result of the department of emergency medical services students recognized type of female 119 paramedics could be typed into four types. The type I is recognized as "Stamina limit type", the type II as "expert type", the type III as "guardian angel type", and the type IV as "feminine experience type". The type I has 28.3%, the type II has 12.7%, the type III has 6%, and the type IV has 3.8% explanation power, and these explain 51% of total variable. Generally department of emergency medical services students' cognition of female 119 paramedic is that they are expert in first aid but students' cognition is negative because of female 119 paramedic's limit of stamina, exposure to danger, and giving birth and infant care thus we should arrange solution of these cognition.

This study was aimed to investigate the estrogenic activity of Di-(2-ethylhexyl) adipate (DEHA) using immatured type uterotrophic assay. SD rats were treated with DEHA (40, 200, 1000mg/kg/day), estradiol-3-benzoate (EB) $(1{\mu}g/kg/day)$ as positive control on the assay. In immatured-type uterotrophic assay, relative organ weights of kidney and reproductive organs such as ovary at high-dose group were significantly increased compared to those of vehicle control group. DEHA did not influence the levels of serum FSH and LH, and uterine morphological changes such as luminal epithelial height, myometrial thickness and numbers of uterine gland, and BrdU indices. In these results, there was no significant variation by DEHA treatment, suggesting that DEHA appears not to be a endocrine disrupter with estrogenic activity.
