이동단말기가 보급이 확산됨에 따라 많은 사용자들이 이동단말기를 사용하고 필연적으로 많은 통신행동을 하고 있다. 특히 SMS 는 시간과 장소의 제한이 적어 사용자들의 통신행동 중 큰 비중을 차지하고 있다. SMS 통신행동에서 이모티콘의 사용이 많이 나타나고 있으며 이는 텍스트 기반의 의사소통의 한계를 극복하기 위한 방안으로 볼 수 있다. SMS 로부터 사용자의 감정을 추론하려는 기존의 연구가 있었지만 SMS 텍스트에 국한된다는 문제점이 있다. 본 논문에서는 최근 휴대폰, PDA, 스마트폰 등 이동단말기의 발전에 따라 통신행동 기록, 위치 정보와 같은 컨텍스트 정보를 수집하고 이용할 수 있음에 착안하여 SMS 텍스트와 함께 이동단말기의 컨텍스트 정보를 추론에 사용하였다. 의사결정트리를 이용하여 가용한 컨텍스트 정보로부터 추론한 정황 정보를 SMS 통신에서 사용하여 기존의 텍스트 기반의 의사소통의 한계를 극복할 수 있는 Visual SMS 를 제안한다. 사전에 정의한 훈련 데이터 집합을 통하여 의사결정트리를 생성하고 이를 기반으로 Visual SMS 를 구현, 시뮬레이션하여 추론 결과를 통해 그 기대효과를 확인한다.

The cases of unidentified individual remains submitted to Forensic dentistry section in National Institute of Scientific Investigation, Korea were analyzed to study the application of forensic dental identification into individual identification in the period 2002-2005. The identification cases of unidentified remains were 405 out of 493, which accounted about 82% of whole cases. The incidence of submission of skeletons at least including the skull was increased from 58% in 2002 to 80% in 2005. The numbers of cases for the full examinations were 4 times more than that for age estimation in 2005. Twenty-four cases were submitted for skull to photographic superimposition and 15 out of 24 cases were examined, and the other 9 cases were examined by DNA analysis only. The submitted cases for dental comparison were 23 cases, 9 cases were positively identified, 4 cases were possible, 7 cases were excluded, and 3 cases ended up with insufficient evidences. The proportion of positive identification by dental methods was increased gradually from 9% in 2002 to 46% in 2005. Forensic dental identification has become important and useful because the availability of dental records and radiographs has been increasing. Compared to DNA analysis, forensic dental identification has several advantages such as no needs for high cost equipments and low expenses. And the interpretation of results is straightforward and speedy. These advantages are based on using primary their own dental records of the individuals rather than secondary DNA reference samples from family members. The application of the forensic dental identification to unidentified individual remains will be increased because the dental comparison can complement the limitation of DNA analysis and skull to photographic superimposition in many cases. In order to obtain positive identifications of unidentified remains, a close collaboration between the police and forensic scientists is important. The systemic approach including legislation to preserve dental records of unidentified remains and missing persons for the identification of unidentified remains should be needed.

The purpose of this study was to explore the cultural perspectives and experiences relating to insulin therapy among the diabetes. The authors conducted four semi-structured focus groups and individual interviews with 19 adults with type 1 and 2 diabetes, focusing on the personal experiences and thoughts regarding insulin therapy. Patients' perspectives and experiences relating to taking insulin formed three categories of themes: preoccupations about insulin, barriers to taking insulin, and benefits to taking insulin. The theme for preoccupations about insulin was "vague fear," while the theme of barriers to taking insulin were "worrisome insulin-related issues", "ambivalent feelings (trust/mistrust) about healthcare providers," "dependent life," "feeling about supporters(family, friends, and religion)," "inconvenience," "regret about the past," and "embarrassment." The theme of benefits to taking insulin were "recognition" and "physical recovery and confidence in regulating blood glucose". Based on this study, patients' feelings about their insulin should be respected by healthcare providers.

Software compliance is an essential process when Open Source Software is included in software development to avoid such as license violation issue. However, analyzing quite big software which involves many developers requires enormous time and hard difficulty. To resolve these kinds of problem, SPDX formalizes and standardize the metadata about the software package. When the use of SPDX is activated, software package analysis would be simple and could contribute fair Open Source Software distribution. In this paper, we develop blockchain based SPDX distribution platform which fulfills the requirement of SPDX lifecycle to provide SPDX database which does not depend on particular centralized service but serve as distributed ledger and control by user's certification and their purpose. Moreover, to contribute invigoration of blockchain based SPDX distribution platform, we develop SPDX document generation plug-in for integrated development environment such as Visual Studio.

This work was conducted to study the improvement of reproduction rate from the breeding data collected from four farms from January 2007 to October 2010. The average numbers of service per conception were 1) A farm $1.7{\pm}0.1$ times, 2) B farm $1.5{\pm}0.1$ times, 3) C farm $1.5{\pm}0.1$ times, 4) D farm $1.4{\pm}0.1$ times. The average days from calving to conception was $77.4{\pm}4.8$ days in A farm, $150.8{\pm}11.2$ days in B farm, $90.4{\pm}4.5$ days in C farm, and $71.4{\pm}2.5$ days in D farm. Number of artificial insemination (AI) service per conception was higher at the 30 days before first AI ($2.1{\pm}0.2$ times) than at the 31 days after first AI, and the days from calving to conception were shorter at the 90 days before first AI than at the 91 days after first AI. After timed AI (TAI) treatment, the pregnancy rate was 60.3% for the 58 cows with reproductive disorder. In order to improvement of reproduction rates, the farms has to improve the accuracy of estrus detection, pregnancy diagnosis, check-up for reproductive health, and control of day for first AI periods after calving. The result suggests that farmers need the careful management and reproductive examination of farm animals to improve of reproductive efficiency.

In the literature, inhalation of cosmetic fragrances, including natural extracts or natural essential oils, has been reported to induce brainwave changes. Angelica gigas (AG) and Cnidium officinale (CO) are widely used in East Asian countries as traditional medicines to improve health, but there have been no previous reports of inhaling their aromas and assessing changes in brain activity through electroencephalogram (EEG) recordings. In this study, the scent of natural herbal extracts such as Artemisia princeps var. orientalis (Compositae), AG, and CO was inhaled and evaluated whether emotional state changes were caused by olfactory stimuli, and brain activity was confirmed through EEG records before and after inhaling the scent of natural herbal extracts in subjects aged 20 to 30. We also used an electrocardiogram (ECG) to record the electrical activity of the heart during fragrance administration. The test results indicated that inhaling the scents of Compositae, AG, and CO extracts, as well as the positive control lavender, significantly increased the relative alpha power and the alpha/beta ratio of brain waves across the brain regions. The ECG recordings indicated that the inhalation of Compositae fragrance significantly decreased the low-frequency/high-frequency ratio, and that the inhalation of traditional herbal extract fragrances resulted in comfort and relaxation.
