Smart city is an urban development vision to integrate multiple information and communication technology(ICT) and Internet of Things(IoT). The goal of building a smart city is to improve the quality of life by using urban informatics and technology to improve the efficiency of services and meet residents' needs. Many devices in today have been used on various industrial regions. These devices use Internet to transfer their informations. We call these situations as the IoT(Internet of Things). We studied various application examples of IoT in smart city industrial region. In this paper, we described two actual cases such as smart park system and smart bin.

Recently, the development of design of cultural goods is focusing on excessively workmanship-oriented craft items. However, an advanced strategy that is practical and develops market-oriented goods in the world needs to be suggested from now on and the selection of goods item aimed to world market is very urgent. Therefore, the purpose of this study was to design practical and worldwide market-oriented shoes with Korean traditional image as a cultural goods. As software tools, 2D Adobe Illustrator Adobe Photoshop and 3D MAX 8.0 Photoshop CS were used to design the shoes. From 8 types of pattern design to which Koran traditional pattern was applied and 7 types of shoe design to which Korean traditional shoes were applied, 60 types of planar shoes design coating developed pattern designs were made. Furthermore, 3D design of cultural goods of shoe made possible to observe it three-dimensionally and accurately from the top, the front and the side respectively. Finally, 43 types of cultural goods of shoe to which Korean traditional shoes were applied were designed successfully according to traditional patterns and colors. The systematic database was established based on the developed pattern design of the shoes and might make the best use of the development of related design of cultural goods. Although there were partly some limitations in the aspects of design and material development of Korean traditional shoes, this study would help the economics of shoe industry in Korea producing high value-added products.

Dynamic stiffness of subsurface materials is one of the most important geotechnical parameters in predicting deformational behavior of structures as well as practicing seismic design and performance evaluation. In an effort to measure the parameter efficiently and accurately, various borehole seismic testing techniques have been, thus, developed and used during past several decades. Moreover, recent rush of underground-space projects and increasing size of structures put more stress on reliable site investigation techniques in estimating stiffness of rock mass. In this paper, a new technique called 'in-hole seismic test' has been implemented to measure the dynamic stiffness of rock masses at subsurface foundations and tunnel-faces. The reliance of in-hole seismic test was evaluated by comparing the testing results at several rock sites with those of other borehole techniques and the technique tunnls out to be an efficient and accurate in-situ testing technique.

Purpose: This study aims to better understand the quality of life (QOL) for Korean breast and gynecological cancer survivors by examining the differences in multi-dimensional QOL outcomes according to stage of cancer survivorship. Methods: To identify the multiple dimensions of health status and psychosocial outcomes, three standardized QOL and psychological distress measures were administered to 110 Korean breast and gynecological cancer survivors. These participants were divided into three groups based on the stage of cancer survivorship. Results: Analyses of covariance revealed that once important confounders were controlled for, QOL outcomes were partially different depending on the stage of cancer survivorship. Results for SF-36 measure showed significant differences between acute and long-term survival stages, indicating that QOL for cancer survivors had gradually improved in the physical domain. However, there were no significant group differences in the psychological domain of SF-36. Additionally, QOL-CS and BSI-18 measures did not show significant QOL differences according to the stage of cancer survivorship. Conclusions: Evidence that, for Korean survivors, QOL outcomes differ according to the stage of cancer survivorship serves as a rationale for developing discriminatory strategies and interventions that take into account survival stage.

K-SGICs(synthetic graphite intercalation compounds) were synthesized in a modified two-bulb pyrex tube. The pressure in the two-bulb tube was maintained at approximately $10^{-3}$ torr for the reaction of potassium and graphite. Deintercalation process of the K-SGlCs obtained by the modified method was heat-treated by keeping in liquid paraffin between $25^{\circ}C$ and $1400^{\circ}C$. The thermal stability and the temperature dependence of the K-SGICs were characterized using differential scanning calorimeter(DSC) analyzer. Enthalpy and entropy for K-SGIC formations were calculated by confirming the deintercalation and thermodynamic exothermic reactions depending on the various temperatures. The structure changes and thermal stability of K-SGICs during the deintercalation reaction of potassium ions and the interlayer spaces of the synthetic graphite were identified by X-ray diffraction(XRD).

대부분의 국내 다목적 댐은 유역면적이 넓고 강우기 집중강우로 인하여 유입되는 입자성 물질이 상당히 많은 편이며, 영양염의 증가로 인하여 저수지내부에서 발생되는 입자성 물질도 많다. 이로 인하여 호소에는 외부에서 유입된 무기$\cdot$유기성 입자와 내부 생성된 유기성 물질들이 장기간 축적되어 저수지 용량이 줄어든다. 본 연구에서는 저수지 퇴적물 상태를 탐사하는 효율적인 조사기법을 제시하고자 한다. 퇴적물 탐사기법에는 탄성파탐사 등을 이용하는 간접적인 방법과 코아를 이용하는 직접적인 방법, 퇴적층 동위원소 분석 기법 등이 있으며, 이러한 기법에 대한 기본원리 및 특성, 효용성 등을 평가하고 현장에 적합한 방법을 실제 적용하였다. 퇴적물 분포를 조사하기 위하여 먼저 다중빔(MBES)을 이용한 정밀 지형조사를 실시하였으며 이를 통하여 호저지형의 특징을 간접적으로 평가할 수 있었다. 직접적인 조사방법으로 gravity corer를 사용하여 몇 개의 지점을 sampling하였으며, 잠수부가 직접 핸드코아링를 실시하여 퇴적층을 측정하였다. 16지점에서 실시한Gravity core 결과 세 곳의 조사 정점에서 최대 70cm 두께의 퇴적층이 중력식 시추기에 의해 획득되었으며 다른 정점에서는 50cm, 20cm가 시추되었고 그 나머지 지점에서는 퇴적물이 채취되지 않았다. 이는 퇴적층이 얇아 코아가 쓰러지거나 시료채취가 되지 않은 것으로 판단되었다. 잠수부가 hand corer를 이용한 시료 채취시에 채취된 시료의 퇴적층은 각 지점별로 덕치리 25cm, 경계지점 25cm, 우산리 지점 45cm로 조사되었다. 납-210(반감기 22.3년)을 이용하여 최근에 형성된 주암댐 호수저 퇴적물 중 퇴적작용 이후 교란을 받지 않은 지역의 시추 시료를 대상으로 퇴적속도를 구하였다. 주암호에서 취한 코아퇴적물 시료는 현장에서 냉동하여 실험실에서 약 2cm 간격으로 절단하여 절단체 별로 동위원소 분석을 실시하였다. $^{210}Pb$의 농도는 grand-daughter인 $^{210}Po$를 측정함 후 감마분석에 의하여 구하였다. CF:CS 연령모델을 적용한 결과 깊이에 따른 supported $^{210}Pb$와 퇴적 속도는 0.91cm/year 인 것으로 산정 되었다.

$K^+$ efflux through a certain type of $K^+$ channels causes the change of membrane potential and leads to cAMP synthesis in the transmembrane cell signaling for the initiation of sperm motility in the salmonid fishes. The addition of $Ca^{2+}$ conferred motility to the trout sperm that were immobilized by external $K^+$ and other alkaline metals, $Rb^+$ and $Cs^{2+}$, suggesting the participation of external $Ca^{2+}$ in the initiation of sperm motility. L-type $Ca^{2+}$ channel blockers such as nifedipine, nimodipine, and FS-2 inhibited the motility, but N-type $Ca^{2+}$ channel blocker, w-conotoxin MvIIA, did not. On the other hand, the membrane hyperpolarization and cAMP synthesis were suppressed by $Ca^{2+}$ channel blockers, nifedipine, and trifluoroperazine. Furthermore, these suppressions were relieved by the addition of $K^+$ ionophore, valinomycin. Inhibitors of calmodulin, such as W-7, trifluoperazine, and calrnidazol-C1, inhibited the sperm motility, membrane hyperpolarization, and cAMP synthesis. The results suggest that $Ca^{2+}$ influx through $Ca^{2+}$ channels that are sensitive to specific $Ca^{2+}$ channel blockers and calmodulin participate in the changes of membrane potential, leading to synthesis of cAMP in the cell signaling for the initiation of trout sperm motility.
