Purpose: This meta-analysis aimed to evaluate the effect of cassia cinnamon (Cinnamomum. cassia and C. aromaticum) on the glycemic response with a focus on the preparation of dehydrated powder and water extract. Methods: We searched Pubmed, Cochrane, EMBASE, Science Direct, and the Korean Studies Information Service System (KISS) through May 2017. In the meta-analysis for the preparation of powder, eight trials reporting fasting blood glucose (FBG), four trials reporting HbA1c, and three trials reporting the postprandial glycemic response were included. For the water extract, six trials reporting FBG and four trials reporting HbA1c were eligible for this study. A random-effects model was used to calculate the pooled effect size. Results: Cassia cinnamon powder intake significantly lowered FBG by -1.55 mmol/L (95% CI, -2.45, -0.64; p = 0.001) and the AUC of postprandial blood glucose level by $-51.8mmol/L{\cdot}min$ (95% CI, -85.5, -18.1; p = 0.003). There was a significant difference in FBG between water extract of cinnamon and placebo of -0.76 mmol/L (95% CI, -1.09, -0.43; p = 0.000). However, blood HbA1c level was not significantly altered by any preparation of cinnamon. No statistical heterogeneity was observed for any analysis except in the case of FBG for cinnamon powder. Results of funnel plots and Egger's regression suggest a low likelihood of publication bias in all biomarkers (p > 0.05). Conclusion: According to this meta-analysis, there was possible evidence to support a relationship between cassia cinnamon intake and fasting glucose in both preparation of powder and water extract. Furthermore, new evidence of the health benefits on postprandial glucose regulation of cinnamon powder was obtained.

The proliferation of online social networking services (OSNSs) and smartphones has enabled people to easily make friends with a large number of users in the online communities, and interact with each other. This leads to an increase in the usage rate of OSNSs. However, individuals who have immersed into their digital lives, prioritizing the virtual world against the real one, become more and more isolated in the physical world. Thus, their socialization processes that are undertaken only through lots of face-to-face interactions and trial-and-errors are apt to be neglected via 'Add Friend' kind of functions in OSNSs. In this paper, we present a friend recommendation system based on the on/off-line contextual information for the OSNS users to have more serendipitous offline interactions. In order to accomplish this, we modeled both offline information (i.e., place visit history) collected from a user's smartphone on a 3D tensor, and online social data (i.e., friend relationships) from Facebook on a matrix. We then recommended like-minded people and encouraged their offline interactions. We evaluated the users' satisfaction based on a real-world dataset collected from 43 users (12 on-campus users and 31 users randomly selected from Facebook friends of on-campus users).

Nowadays, studies on the fusion of Semantic Web technologies are being carried out to promote the interoperability and value of sensor data in an IoT environment. To accomplish this, the semantic translation of sensor data is essential for convergence with service domain knowledge. The existing semantic translation technique, however, involves translating from static metadata into semantic data(RDF), and cannot properly process real-time and large-scale features in an IoT environment. Therefore, in this paper, we propose a technique for translating large-scale streaming sensor data generated in an IoT environment into semantic data, using real-time and parallel processing. In this technique, we define rules for semantic translation and store them in the semantic repository. The sensor data is translated in real-time with parallel processing using these pre-defined rules and an ontology-based semantic model. To improve the performance, we use the Apache Storm, a real-time big data analysis framework for parallel processing. The proposed technique was subjected to performance testing with the AWS observation data of the Meteorological Administration, which are large-scale streaming sensor data for demonstration purposes.

Obwohl die Preisbekanntmachung der individuellen Gesundheitsleistung(PiG), die im Jahr 2010 im Arztrecht neu eingef$\ddot{u}$hrt wird, zum Management der Gesundheitskosten sehr n$\ddot{u}$tzig werden soll, muss eine verfassungsrechtliche Rechtfertigungspr$\ddot{u}$fung von PiG zun$\ddot{a}$chst durchgef$\ddot{u}$hrt werden. Angesichts der staatlichen Regulierung und Lenkung auf die Wirtschaft des Art. 119 Abs. 2 KV besitzt die PiG zun$\ddot{a}$chst eine Verfassungsrechtfertigung. Nach der st$\ddot{a}$ndigen Rechtsprechung des koreanischen Verfassungsgerichts folgt das Selbstbestimmungsrecht der Verbraucher aus der Menschenw$\ddot{u}$rde von Art. 10 Abs. 1 Koreanische Verfassung(KV) und dem Recht auf Gl$\ddot{u}$ck von Art. 10 Abs. 2 KV. Demnach k$\ddot{o}$nnen Konsumenten den Einkauf der G$\ddot{u}$ter und Service, die Partei des Vertrags, Gesch$\ddot{a}$ftsbedingungen, usw. frei entscheiden. Indem der Preis der individuellen Gesundheitsleistung mithin bekanntgemacht wird, werden das Selbstbestimmungsrecht der Verbraucher sowie das Recht der Konsumenten sicherlich gew$\ddot{a}$hrleistet. Dar$\ddot{u}$ber hinaus steht die PiG im Einklang mit dem Recht auf Information, aber auch z$\ddot{a}$hlt sie nicht zu den Informationen der Nichtbekanntmachung vom Gesetz $\ddot{u}$ber die Bekanntmachung der Information(GBI). Nach der staatlichen Gesundheitspflicht des Art. 36 Abs. 3 KV kann die PiG eine Verfassungslegitim$\ddot{a}$t besitzen. Im Hinblick auf die Berufsfreiheit kann die PiG einen Eingriff in den Gesch$\ddot{a}$ftsaktivit$\ddot{a}$ten der Unternehmen bedeuten. Trotzdem ist die PiG als eine verfassungsrechtliche Legitimit$\ddot{a}$t zu qualifizieren. In der Konsequenz kann die PiG, die auf dem Selbstbestimmungsrecht, dem Recht auf Information, dem Gesundheitsrecht, der Regulierung und Lenkung auf die Wirtschaft von Art. 119 Abs. 2 KV, und dem Recht der Verbraucher beruht, als eine verfassungm${\ddot{a}}{\ss}$ige Politik gesch$\ddot{a}$tzt werden.

The aim of this study was to investigate the effects of death education on the attitude toward DNR, fatigue, and quality of sleep for generic care worker. This study followed a nonequivalent control group and a non-synchronized design. This study was performed in a visiting generic care service institution in J city, Chung-Cheong province, Korea between February 15 to May 30, 2016. The study included 43 participants who agreed to participate in this study. They were randomly divided into two groups: 21 participants in the experimental group and 22 in the control group. Participants in the experimental group received death education 2 hours per day, once a week, for a duration of greater than 8 weeks. The effect of treatment was measured using a structured questionnaire on the attitude toward DNR, fatigue, and quality of sleep before and after 8 weeks of intervention. Data were analyzed using t-, chi-square, Fisher Exact- and paired t-tests. The experimental group showed a significantly increased attitude toward DNR (p=0.001) and quality of sleep (P<0.001), whereas significantly decreased attitude toward fatigue (p=0.030) than the control group after 8 weeks of intervention. The death education program was shown to be an effective nursing intervention for generic care workers. Therefore, we can consider the possibility of incorporating death education in the nursing program.

This study draws the following conclusions about the nature garden culture with crane that is a dynamic landscaping factor introduced into nature garden by analyzing the literatures on cranes written and landscapes painted in Chosun Dynasty. First, crane symbolizes such Buddhist, Taoist and Confucius media as appearance of Buddha, desire for Taoist hermit world and long life, and a solitary's life of proud loneliness. It has been recorded that crane was raised from the Three Nations Era till the Japanese occupation and Confucius scholars in Chosun Dynasty opened shows concerning crane or formed literature groups enjoying poems of it, and often using crane as their denial of going into government service. Second, in order to introduce crane to nature garden, people caught wild crane and made a fence and some kind of pond for their growth. In addition, crane was strictly managed by appointed slaves and they trained crane for dancing and then tended to allow a crane to play on the yard in terms of abstract meaning or got two cranes free in consideration of their ecology. Third, for more appreciation of crane and the expression of some symbolism matching for it, both plum and pine, which mean a solitary's life and long life respectively, were planted in nature garden. And, Confucius scholars in Chosun Dynasty also enjoyed their refined tastes with appreciation, napping, reading and playing the harp, accompanied by crane. As aforementioned, Confucius scholars in Chosun Dynasty did not only draw the meaning symbolized by cranes and write poems about such symbolic meaning, but also positively introduce crane into nature garden as a dynamic landscaping factor, so that they enjoyed synesthetic senses including looks, motions and sounds of cranes for their refined tastes.

효과적인 ATM 망의 관리는 연결 지향 환경, 다양한 서비스 등급, 대규모 트래픽, 가상 망 구성 그리고 여러가지 트래픽 유형 등과 같은 다양한 ATM 특성을 다룰 수 있어야만 한다. 이를 위해 ATM 포럼에서는 ATM 장치, 사설망, 공중망 및 그들간의 상호작용을 지원하기 위한 ATM 망 관리 참조 모델을 정의하였으며, 그 중 하나가 서로 다른 판매자로부터의 ATM 장비들간의 상호동작성을 보장하기 위해 SNMP 기반 망 관리 프로토콜을 통해 상호 연결된 인터페이스를 관리할 수 있도록 정의된 통합 지역 관리 인터페이스(ILMI) 프로토콜이다. ILMI의 목적은 두 인접한 ATM 장치로 하여금 그들 간에 공통의 ATM 링크에 대한 동작 파라메타를 자동적으로 구성할 수 있도록 함으로서, 관리자에 의해 수동 구성이 아닌 ATM 장치 상호간의 플러그 앤 플러그 기능을 지원하는데 있다. 본 논문에서는 이러한 ILMI 기술을 바탕으로 공중망 ATM 교환기에 연결된 가입자의 물리 인터페이스, ATM 계층 인터페이스, VPC 및 VCC의 구성 및 상태 정보를 효율적으로 관리하며, 가입자 시스템의 ATM 주소를 자동으로 등록, 관리할 수 있도록 하는 가입자 인터페이스 관리 시스템(SIMS)을 설계하고, 구현하였다. Abstract An effective ATM management must address the various features of ATM such as connection-oriented environment, varying class of service, large scale traffic, virtual network configurations and, and multiple traffic types. For this, ATM network management reference model defined by ATM Forum describes the various types of network management needed to support ATM devices, private networks, public networks, and the interaction between them. One of these types is Integrated Local Management Interface (ILMI) defined to manage interconnected interface through SNMP-based network management protocol for ensuring the interoperability of ATM devices from different vendors. The purpose of ILMI is to enable two adjacent ATM devices to automatically configure the operation parameters of the common ATM link between them and then to provide a Plug and Plug function to any ATM devices with not a passive configuration by manager but a automatic configuration. This paper design and implement a Subscriber Interface Management System (SIMS) which provide automatic registration and management of ATM address of subscriber system and efficiently manages physical interface of subscriber who is connected to public ATM switch, ATM layer interface, configuration information and status information of VPC and VCC.

The purpose of this study was to examine whether senior simulation would bring any positive change to the attitude of dental hygiene students toward the elderly. The experimental group consisted of 58 dental hygiene students at a college. The experimental procedure was to do activities for 40 minutes wearing aging simulation suit. Self administered questionnaires were used to ask the attitude toward the elderly after senior simulation. The data were analyzed with SPSS program. General and aging related characteristics of subjects were analyzed through descriptive statistics. To testify the differences of the attitude after senior simulation, paired t-test was used. An experiment was conducted from May 27 to June 14, 2012, and the findings of the study were as follows: 1. There wasn't any perfect positive change in the overall attitude of the students toward elderly people after senior simulation, but their attitude got a little more positive whereas they took a neutral attitude in the past; 2. The students who had ever lived with elderly people under the same roof and who had ever received education related to the elderly underwent a more positive change in their attitude toward the elderly; 3. To what extent senior simulation was helpful for the understanding of the elderly was checked, and the majority replied that it was very useful or useful for the understanding of their physical aspects. The findings of the study confirmed that senior simulation didn't change the overall attitude of the students toward the elderly in a positive way yet brought about some positive changes in part. Therefore senior simulation is expected to be one of significant educational programs that could encourage students to have a better physical understanding of the elderly, to take a more positive attitude to them and to provide them with quality dental service.
