      • Development of a Mobile Application, "Wild Flowers of Bukhansan National Park (version 1.0)", for Identification of Plants in Bukhansan National Park

        Kim, Sang-Tae,Lee, Seung-Yeon,Kim, Seung-Chul,Byun, Hye-Won,Lee, Sang-Tae,Kim, Mu-Yeal,Hong, Seok-Pyo,Chung, Young-Jae,Park, Ki-Ryong,Lee, Chung-Hee,Lee, Joong-Ku,Heo, Kyeong-In,Lee, Ji-Ye,Lee, Eun-Je National Science Museum of Korea 2011 Journal of Korean nature Vol.4 No.3

        We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

        이영지(Young-Ji Lee),이희열(Hee-Yeol Lee),고태영(Tae-Young Ko),곽동훈(Dong-Hoon Kwak),김재형(Jae-Hyung Kim),김주호(Joo-Ho Kim),오승진,이태윤(Tae-Yoon Lee),박상민(Sang-Min Park),이승호(Seung-Ho Lee) 대한전자공학회 2019 대한전자공학회 학술대회 Vol.2019 No.6

        In this paper, we propose a program to identify 14 parking status in a parking lot using a high resolution 360° camera of 12M. The proposed program consists of three steps: Match with plane image, parking area detection algorithm, and discrimination of parking using learning method. Tests on a model car to evaluate the program to identify 14 parking status in a parking lot using a high-resolution 360° camera of 12M showed 100% accuracy for both parking and double parking. Therefore, the effectiveness of a program to identify 14 parking status in a parking lot using a high-resolution 360° camera of 12M proposed in this paper has been proved.

      • [논문]Operational Characteristics of CO2 Laser Adopted by Superposing-Discharge

        Hee-Je Kim,Hyun-Ju Chung,Byoung-Dae Min,Jong-Han Joung,Sung- lun Park 釜山大學校生産技術硏究所 2003 生産技術硏究所論文集 Vol.62 No.-

        오늘날 현저한 CO2 레이저의 응용 추세에 발맞추어 보다 다양한 형태의 출력 제어 기술이 대두되고 있다. 본연구에서는multi-Pulse Superposing-Discharge 기술을 이용하여 다양한형태의 CO2 레이저의 펄스를 성형 하였다. 펄스 성형을 위한 방법으로 PIC one-chip microprocessor를 이용하여 삼중 PFN 모률의 SCR을 각각 고유의 지연시간을 가지도록 제어하였다. 실험에 사용된 삼중 PFN 모률의 전원 회로는 각각 캐패시터 인덕터,SCR,고압 펄스 트랜스 그리고 고압 트랜스 2차측에 브릿지 정류기로 구성 하였다. 고압 펼스 트랜스의 1차측을 제어하므로서 PFN 모률의 동작을 저 전압에서 수행 할 수 있다. 트랜스의 2차측에 연결된 전파 정류기는 펄스 에너지를 부하에 지속적으로 전달한다. 본 연구에서는 삼중 PFN 모률의 각각의 SCR을 다른 시간 가격을 두고 트리거 하므로서 다양한 Long pulse shaping을 실현하였다. 또한 약 250-1000μs 의 주기를 가지는 다양한 펄스형 레이저 빔을 얻었다.

        朴哲浩,朴吉俊,李相于,金永明,朴贊熙,玄松子,呂南會,朴相甲,金榮俊 東亞大學校附設스포츠科學硏究所 1989 스포츠科學硏究論文集 Vol.7 No.-

        This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

        The purpose of this study was to examine the timing and sequence of growth and development velocity curves of some physique and physical fitness aligned on age at peak height velocity. The study design, the subjects, and the method used in cross-sectional investigation reported by Ministry of Physical Education and Youth of Korea(1989). According to the reported by Ministry of Physical Education and Youth, the subjects participated in goverment study were 7 through 50 over years of age who belonged to typical primary, junior and senior high school, college and adult, and about 550 males and 550 females in each age. Thus, the total sample size were 6,316 males and 6,316 females. Grand total was 12,632. For physique measured, 2 body linearity items ; body height and sitting height, 5 body bulk items ; body weight, chest girth and 3 site skinfold thickness items were selected. For physical fitness measured, 8 items such as grip strength, sit-ups, 10m shuttle run, standing long jump, 50m dash, long distance run, eyeclosed foot balance and trunk flexion were selected. Measurements were actually worked out in April through July, 1989. The mean and the standard deviation were computed for each itesm, each age, and each sex, respectively. The growth and development velocity magnitudes of some physique and physical fitness in this study were calculated by personal computer. The conclusion obtained as follows. 1. Ages at PHV occurred earlier about 3years than males on the average. 2. Maximal annual increments (PV) in body weight, chest girth and sitting height appeared to coincide with PHV in males, but, to about 1 and 2 years after PHV in females. 3. Two occurrence of peak velocity gained in the chest girth for males and 3 site skinfold for females. In contrast, peak velocity of triceps skinfold was not appeared in males. 4. Peak velocities of grip strength and trunk flexion occurred about 1 to 2 years after PHV in both sexes. Peak velocities of 50m dash and long distance run occurred about 1 to 2 years after PHV in males. 5. Peak velocities of sit-ups, standing long jump and eyeclosed foot balance occurred about 1 to 2 years before PHV in both sexes, respectively. 6. Peak velocity of 10m shuttle run was not occurred in both sexes, peak velocity of 50m dash was not occurred in females. 7. Generally, peak velocities of physique and physical fitness occurred earlier about 1 to 3 years in females than in males.

        Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

        흰쥐 Kupffer 세포에 대한 Propofol의 작용

        박세훈,지대림,성언기,김희선,송인환,박희영,김준수,이덕희,박대팔 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.4

        Background: Propofol has an antioxidant capacity and can be used for ischemia-reperfusion injury of the liver. However, the effects of propofol on the Kupffer cells have not been establisked. Methods: Kupffer cells were isolated and cultured from male Sprague-Dawley rats. The effects of propofol on the Kupffer cells were evaluated by a phagocytosis assay, TNF-α gene expression, and superoxide anion release after administering propofol in different concentrations on the cultured Kuprrer cells. Results: The latex bead phagocytosis by the Kupffer cells was suppressed when the Kupffer cells were exposed to propofol irrespective of concentrations. Higher propofol concentrations decreased the loss of Kupffer cells after latex bead phagocytosis. Propofol induced TNF-α mRNA expression in the Kupffer cells, but the mRNA expression level after 50㎍/ml of propofol decreased. The pattern of TNF-α mRNA expression induced by propofol was different to that induced by LPS: TNF-α mRNA was expressed continuously in the propofol-treated cells until 16 hours after exposure to propofol, whereas the level of TNF-α mRNA expression induced by LPS was evident after 2 hours and was not found thereafter. TNF-α production after propofol treatment was not higher than that of the control. Formazan presipitation did not show any qualitative differences between cells untreated or treated with propofol concentrations of 0.5, 5.0, and 50 ㎍/ml. Conclusions: These results showed that propofol might inhibit Kupffer cells. This suggests that propofol and be used for patients with ischemia-reperfusion injury of the liver.

      • UPS Applying Big Data Analytics to Logistics:

        Sung-Hee “Sunny” Park,Do-Hong Kim 한국경영정보학회 2014 한국경영정보학회 학술대회논문집 Vol.2014 No.1

        Managing big data has become increasingly important to businesses as big data analytics can transform big data into insightful information. But, not many companies utilize it efficiently and effectively. While many companies in the transportation industry are facing many challenges with big data, United Parcel Service (UPS) is successfully applying big data analytics to logistics. UPS’s proprietary routing software, called ORION (On-Road Integrated Optimization and Navigation), uses package-level detail and customized online map data to provide drivers with optimized routing information. In 2013, ORION resulted in reductions of more than 1.5 million gallons of fuel and 14,000 metric tons of CO2 emissions. This paper discusses UPS’s innovative path to optimization from data gathering to visualization.

        수사적 상황과 역할에 따른 대통령 수사학 장르 분석

        박성희(Sung Hee Park),이자원(Jawon Lee),석지윤(Ji Yoon Seok) 한국수사학회 2013 수사학 Vol.0 No.19

        Rhetorical genre represents a class of messages having important structural and content similarities that creates special expectations among listeners. Presidential rhetoric delivers textual features to the similar effect of creating trust and bonding people. Based on the arguments of Bitzer and Hart, this study attempts to compare and contrast two presidential addresses that were delivered in two different time and spacial settings. For this purpose, former President Park Jung Hee’s 1963 National Press Club address in Washington and President Park Geun Hye’s 2013 address in U.S. Congress in Washington were chosen. As analytic tools, Hart’s credibility strategy index and I-reference style were used, along with Bitzer’s elements in rhetorical situation. The results indicated that two Presidents showed similar patterns in their use of credibility strategy and use of I-reference positioning them in a certain role in their speeches. While two speeches, each of which 48 years apart, revealed different rhetorical situations in terms of their exigences, audiences, and contraints, respective presidents retained similar generic features in their addresses. From the results, it could be discussed that the presidential rhetoric as a generic form has a unique construct of communicating messages that pronounce their unique social role and solidate trust system in society.
