In this Study, Social Network Analysis of IoT related patents in South Korea, China, and Japan was conducted from the viewpoint of patent informatics. To this end, 2,526 patents filed by PCT until December 2019 were investigated up to the subclass level of the IPC code. As a result, in the case of South Korea, representative IPC codes are in the order of G06Q, H04L, G06F, H04W, and the highest frequency of interconnection is H04L→H04W, H04W→H04L, H04W→H04B. In China, the representative IPC codes are in the order of H04L, H04W, G05B, G06Q. South Korea has strong technological convergence centered on the G06Q, while China has strong convergence centered around H04L and H04W. Moreover, in China, H04L and H04W have more diverse combinations than in South Korea in Section A, B, G, and H. In the future, it is necessary to study the diversity of technology convergence of H04L and H04W in China.

최근 공공안전 분야에서는 국민의 위험상황을 분석하여 선제적으로 예측을 하여 국민의 안전을 보장하기 위한 요구사항이 대두대고 있다. 또한 스마트폰 및 스마트워치와 같은 고성능 모바일 단말 기기들의 대중화로 인해 해당 기기들에 부착된 다양한 센서 데이터들을 융복합하여 분석할 경우, 수집한 센서 데이터의 잠재적 가치를 안전보장 측면에서 사용할 수 있는 장점이 있다. 본 논문에서는 대인, 대물, 장소에 해당하는 로그 데이터들을 융복합 분석하여 보호대상자의 안전을 지원하는 다중로그 플랫폼 기반 이동경로 분석 기법을 제안한다. 다중로그 플랫폼에서 수집하는 보호대상자의 이동 경로 궤적을 활용하여 과거에 축적된 이동경로 패턴과 비교를 통해 현재 경로가 평소에 이용하던 경로와의 유사도를 추천하게 된다. 해당 이동 경로 분석 시스템은 위치기반 멀티모달 센서 데이터를 융복합 하여 보호대상자의 안전을 보장하는데 기여 할 것으로 예상된다.

The purpose of this study was to describe the semantic system and process of posttraumatic growth experience of firefighters after colleague's suicide. Grounded theory methodology based on symbolic interactionism was utilized. The subjects of this study were 7 firefighters who experienced the colleague's suicide. Data were collected by using in-depth interviews from October 1 to November 30, 2015. The results showed that "Gradually becoming more resilient" was analyzed to be the core category of firefighters' posttraumatic growth. We derived four categories and nine subcategories. Based on the results, it is necessary to develop a convergence intervention program to promote posttraumatic growth of firefighters exposed to various traumatic events.

The purpose of the study was to investigate the attitudes towards death and euthanasia of Nurses and Nursing students live in convergence era. The participants were 380 nurses and nursing students and data were collected from May until June of 2014. The data were collected by means of self reported questionnaires and analyzed using descriptive statistics t-test, one-way ANOVA and Scheffe test with the SPSS/WIN 18.0 program. The result showed that the fear of death of others with nursing students was higher than nurses (t=-3.34, p=.001) and nursing students supported euthanasia more than nurses(t=-3.06, p=.002). Among the death attitude, both of the nurses and the nursing students had the highest score 'fear of their own dying' and the lowest score 'fear of the dying of others'. Regarding attitude to euthanasia, both of them the most important factor was 'the right of the client'. These results suggest that death education program to deal with nursing services without ethical conflicts should be developed.

Smartphone game market, smart phone appeared on the market and soon developed rapidly, generation change is happening. Generally, Smartphone games are only short-lived super cell's Clash of Clans is gaining popularity for over two years. So Clash of Clans this game with hold most characteristic elements of the defense and plunder on the subject analyzed the fun factor. In order to analyze the defense and plunder elements were prepared Clash of Clans and Kings of Thieves in cases. Two of the cases, depending on the fun theory Preparation, A sense of space, A solid core machanic, A range of challenge, A range of abilities required to solve the encounter and Skill required in using the abilities were evaluated in the fun factor analysis of defense and plunder elements.

Social Network Service is one of platforms rapidly growing in the environment of digital convergence. Most of researches regarding social network service(SNS) done up to the present time are concerning about technic and effectiveness characteristics of SNS. However, this study focuses on the roll of self-disclosure in the use of social network services(SNS). From the perspectives of personal and social motivation rather than the effectiveness and technic characteristics of SNS. the relations among self-disclosure, enjoyment, social ties and intention to use have been tested empirically. The results from this study shows that self-disclosure has not directly effects on the intention to use of SNS, but indirectly effects on it through personal enjoyment and desire to have social ties.

The purpose of this study was to examine the effects of the Happy Village Convergence Program on the depression, meaning of life and suicidal ideation in rural elderly women. The participants of this study were 25 elderly women aged 65 years or older in G province (12 experimental group and 13 control group). The data collected from January 10, 2019 to March 14, 2019. The experimental group participated in the 10-session program, once a week for 60 minutes. The data were analyzed using descriptive statistics, ${\chi}^2-test$, and t-test. There were significant differences in depression (t = -2.195, p <.05) and meaning of life (t = 2.757, p <.05) in the experimental group compared to the control group. Therefore, the program was effective in rural women. We propose further study to confirm the usefulness of the program by expanding the gender and area.

This paper aims to propose a novel technology of network convergence to provide ultra high speed internet services over CATV networks, by which a CMC(cable modem concentrator) and CM(cable modem) of 1Gbps level are designed. This technology not only lowers the production cost in comparison to the existing bonding technology with DOCSIS specification but also enables the adjustment of data speed based on the channel bandwidth. According to the experiments, when convolutional code rate with 128QAM is changed to 1/2, 2/3, 3/4 and 7/8, the data recorded the maximum transmission speed of up to 299 Mbps at the zero error rate. As the convolutional code rates with 256QAM is increased, it showed 334Mbps at the error rate of $10^{-5}$. Based on the findings of this paper, if we secure the channel bandwidth of 200MHz and adjust the modulation order of QAM and the convolution code rate depending on the channel status, we can get the transmission speed of more than 1Gbps, which is much more competitive in its function and price than the existing technology based on DOCSIS.
