This study was conducted to identify the impact factors of bicycle driving under the influence (DUI) among Korean adults. The participants were 1,297 Korean adults. The prevalence of bicycle DUI was 11.7% of Korea adults. The factors affecting bicycle DUI were gender, education level, frequency of drinking, one-time drinking, vehicle DUI. To prevent bicycle DUI, we would need to facilitate appropriate drinking habits, provide treatments for disorders related to alcohol use, and change the social perception of bicycle DUI. Also, we should promote the establishment of the culture of bicycle helmet use, the establishment of a system that imposes fine to non-helmet-using riders, and education and publicity on the national level to recognize that bicycle DUI and DUI are mutually related.

Objectives Obsessive-compulsive disorder (OCD) is a chronic and disabling psychiatric disorder. The duration of untreated illness (DUI) has been suggested as one of the predictors of clinical course and outcome in various psychiatric disorders. There is increasing evidence that cognitive dysfunction is associated with the prognosis of OCD. The aim of this study was to investigate the influence of DUI on the neurocognitive functions in patients with OCD. Methods Sixty-two patients with a DSM-IV diagnosis of OCD from the outpatient clinic were included in this study. We defined the short DUI if the DUI was 2-year or less and the long DUI if it was longer than 2-year. Neurocognitive functions were assessed by visuospatial memory function test and 4 subsets of K-WAIS such as vocabulary, arithmetic, block design and picture arrangement. Differences in neurocognitive functions as well as clinical variables between OCD patients with short DUI and those with long DUI were investigated. Correlation analyses were also performed to determine the correlation between DUI and neurocognitive functions. Results Compared with the short DUI group, the long DUI group performed worse in the block design test, which measures executive function. The long DUI group also had a higher level of compulsive symptom severity than the short DUI group. However, the DUI was not correlated with neurocognitive functions. Conclusions Findings in this preliminary study suggest that the long DUI in patients with OCD is associated with more severe executive dysfunction. Studies with larger samples and longitudinal design are needed to further confirm the prognostic role of the DUI in OCD.

본 논문은 IP Camera 사용자 인증 시 인증 방법을 향상하는 목적에 있다. 기존 인증은 지식기반 인증 방식을 이용하기 때문에 공격자의 공격에 ID, PW가 노출되면 IP Camera는 공격자에게서 무방비상태가 된다. 공격자는 IP Camera에 접속하여 실시간 영상과 음성을 획득, 유포하여 2차 범죄로 악용될 수 있고 비밀시설의 설치된 경우 비밀누설의 우려가 있다. 이러한 취약점을 보완하기 위해 본 논문에서는 DUI(Device unique identifier)를 이용하여 Device를 식별, 등록하고 IP Camera에 Device를 종속시켜 허가되지 않는 Device의 접근을 막고 허가된 Device만 인증하는 DUI 인증을 제안한다.

본 연구는 제7기 1차 년도 국민건강영양조사 원시자료를 이용하여 한국 성인의 자전거 음주운전과 차량 음주운전의 관련성 및 차량 음주운전에 미치는 영향요인을 파악하기 위한 서술적 조사 연구였다. 연구대상자는 3,385명이었고, 한국 성인의 음주운전 경험률은 7.8%였다. 한국 성인의 자전거 음주운전과 차량 음주운전은 통계적으로 유의한 차이가 있었고, 차량 음주운전의 영향요인은 자전거 음주운전, 유산소 신체활동, 1회 음주량, 폭음빈도, 음주운전 차량 동승횟수로 나타났다. 결론적으로 한국 성인의 차량 음주운전을 예방하기 위해 일상생활 및 직장생활에서 유산소 신체활동을 할 수 있도록 권장하고, 자전거 음주운전이 차량 음주운전으로 이어질 수 있음을 인식시켜야 하겠으며, 알코올 사용 장애자의 관리와 음주 전 차량운행에 대한 계획을 수립하는 것이 필요하다.

The gasoline direct injection (GDI) system is considerably spreading in automotive market due to its advantages. Nevertheless, since GDI system emit higher particle matter (PM) due to its combustion characteristics, it is difficult to meet strengthened emission regulation in near future. For this reason, a combined GDI with MPI system, so-called, dual injection (DUI) system is being investigated as a supplemental measure for the GDI system. This paper focused on power and fuel consumption effect by injection mode strategy of DUI system in part load and idle engine operating condition. In this study, port fuel injectors are installed on 2.4 liters GDI production engine in order to realize DUI system. And, at each injection mode, DOE (design of experiment) method is used to optimize engine control parameters such as dual injection ratio, start of injection timing, end of injection timing, CAM position and so on. As a consequence, DUI mode shows slightly better or equivalent fuel efficiency compared to conventional GDI engine on 9 points fuel economy mode as well as MPI mode shows less fuel consumption than GDI mode during idle operation. Furthermore, DUI system shows improvement potential of maximum 2.0% fuel consumption and 1.1% performance compared to GDI system in WOT operating condition.

The effects of electroacupuncture on gastric motility in dogs were investigated in this study. The acupoints used in this experiment were Zu San Li (ST-36), Feng Long (ST-40), Jie Xi (ST-41), and Li Dui (ST-45) which belong to stomach meridian, Wei Shu (BL-21) which belongs to urinary bladder meridian, and Zhong Wan (CV-12) which belongs to conception vessel meridian. The animals were stimulated with 2-4 volt and 5 Hz for 20 min. Electroacupuncture at Zu San Li and Wei Shu acupoint increased the gastric motility, but Zhong Wan decreased the motility. There were no change in gastric movement after electrostimulation at Feng Long, Jie Xi and Li Dui acupoints. It was considered that electroacupuncture at Zu San Li and Wei Shu acupoints to promote the gastric movement, and at Zhong Wan acupoint to depress the movement might be effective in veterinary practice.

We derived following result by organizing research about processing of medicinal of before Han(漢) dynesty. The human being intake of natural substance for the purpose of treatment was what happened later than the use of natural substance as food. According to the record of by the early years of Shang(商) dynasty, we can assume that we cooked food with water and fire. The reason why there is no appearance of common production that can be included under the name of 'Tang Ye(湯液)' in the medical record discovered from Ma Wang Dui(馬王堆) is because 'Tang Ye' was yet developed. However, as the presentation of format of medicine process, there was gradual formation of medicinal fluid concept. There are quite of records on major details of cloth manufacture like washing and selection, grinding, processing of medicine from the recordings of "Wu Shi Er Bing Fang(五十二病方)", "Yang Sheng Fang(養生方)", "Za Liao Fang(雜療方)" discovered at Ma Wang Dui. It used words like 'Ze(擇)', 'Qu(去)' for the selection and 'Jiu(酒)', 'Zhuo(濯)' for the wash as a process method before cloth manufacture. When filter the processed medicine, it used words like 'Zhuo(捉)', 'Suo(索)', 'Jun(浚)' and used 'Yin Gan(陰乾)', 'Bao(暴)', 'Yang(暘)' for dry. The 'cutting(切削)' that crushes the medicine used different names based on the properties of medicines. The most frequent crush is 'Ye(冶)' and it means the powered medicine after dry. There was thermal process of mild fire(微火) and heating of 'Wen(溫)'. There are many states of medicine seen from the medical record discovered at Ma Wang Dui so they can be said as original medicine. 藥末劑 is relatively commercialized type then. Here, it includes later 湯劑 but there was no name such as 'decoction(湯)' or 'decoction of medical ingredients(湯液)'. Also, 'Fu Ju(㕮咀)' is the transformation of what was 'Fu Qie(父且)' at "Ja Liao Fang" of medical books of Ma Wang Dui with time flow. The original meaning of 'Fu Qie(父且)' is 'Fu Zu(斧俎)' and it means the crushing medicine with axe. The most important thing among the medical books of Han dynasty is "Shen Nong Ben Cao Jing(神農本草經)" and "Shang Han Za Bing Lun(傷寒雜病論)" of Zhang Zhong Jing(張仲景). "Shen Nong Ben Cao Jing" mentioned the dry method of medicine, collection and process production time, cooked and uncooked use of medicine and there are several types of medicine. Other than those, it mentioned 'Seven methods of combining herbs(七情合和)' to address cautions for combining medicines. Therefore, the 'processing of medicinal' in east Han dynasty period entered the theoretical step. However, there is only little recording on cloth manufacture of detailed medicine. From the "Shang Han Za Bing Lun" of Zhang Zhong Jing, the development in the way of 'processing of medicinal' reveled the cloth manufacture for each medicine. This tradition is continued until today and so it presents the development of purpose of 'processing of medicinal' is to greatly present the effect of medicine and to reduce the side-effect.
