Real-time data reduction pipeline for the Korea Microlensing Telescope Network (KMTNet) was developed by Korea Astronomy and Space Science Institute (KASI). The main goal of the data reduction pipeline is to find variable objects and to record their light variation from the large amount of observation data of about 200 GB per night per site. To achieve the goal we adopt three strategic implementations: precision pointing of telescope using the cross correlation correction for target fields, realtime data transferring using kernel-level file handling and high speed network, and segment data processing architecture using the Sun-Grid engine. We tested performance of the pipeline using simulated data which represent the similar circumstance to CTIO (Cerro Tololo Inter-American Observatory), and we have found that it takes about eight hours for whole processing of one-night data. Therefore we conclude that the pipeline works without problem in real-time if the network speed is high enough, e.g., as high as in CTIO.

In this thesis I tried to unearth some Korean Akjang, written and sung by Korean language, not by the form of Chinese verses. In 19th century they used the Korean Akjang at Court banquet cerymony in Chosun Dynasty. I had got four meaningful conclusions through this study, as follow. 1. There are various banquets but they used Korean Akjang only at YaYeon, a sort of night banquet. 2. The Akjangs arranged at YaYeon are called Ak-ka-Samn-jang which means three songs at the banquet. 3. These Akjangs were usually composed of 3 pieces of Gagok, the Korean traditional vocal music, as one. 4. The Kings and princes wrote all the words of these music.

The library is the most frequently utilized building on campus, but, it has been reported to be a facility most vulnerable to crime. However, almost no study has been conducted on crime in the library, which implies a need for research on the subject. The purpose of this study is specifically twofold. First, this study will suggest components of environmental plan to prevent fear over library crime on campus. Second, the study seeks to reveal the correlation between use per library space and fear of crime. This has been analyzed by conducting a survey among current university students, and the survey includes the following three details: first, fear over day/night crime per library space; second, components of environmental plan to prevent fear over crime per library space; third, level of use per library space on campus. The results of study show that fear of crime has low relation with crime occurrence, fear per library space is higher during the night than during the day, and the space where the fear level is usually high is the service facility. There is a difference for each space in terms of important components of environmental plan to prevent crime per library space, and installation of security device is most important. One must consider a plan for a crime safe environment regarding library space where the level of use during the day is low.

A 52-year-old female diagnosed with Atypical Parkinsonian Disorders (APD) about one year ago suffered from dizziness and gait disturbance. The patient was identified as Taeeumin esophagus-cold lung-dry symptomatology pattern and was treated with Jowisengcheong-tang. The patient's symptoms of dizziness and night sweats were assessed using Global Assessment Scale (GAS). And, the Unified Multiple System Atrophy Rating Scale (UMSARS) and the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) were used to assess the overall function of the patient. The patient's symptoms of dizziness and night sweats were significantly improved, and UMSARS and MDS-UPDRS scores were decreased. This case showed that Sasang constitutional medicine treatment can improve APD symptoms and improve the quality of life of the patient.

An 80-year-old Korean woman who previously experienced penicillin allergy presented to a dental hospital for treatment of a fractured tooth. A dentist extracted the tooth and prescribed her A-cillin (amoxicillin hydrate) 250 mg orally 3 times a day for 3 days and Carol-F^® (ibuprofen arginine) orally 3 times a day for 3 days. She received the prescriptions, returned home, and took one dose of each drug. One hour later, she experienced hypertension, itching, shortness of breath, and was unable to move her tongue to pronounce words. Approximately 6 hours after drug administration, the symptoms persisted, and the patient was admitted to an emergency medical center (EMC). The patient was discharged from the EMC after a one-night stay in the hospital for symptomatic treatment.

This paper considers the ability of counting and positioning multi-targets by using a mobile UWB radar device. After a background subtraction process, distinguishing between clutters and human body signals, the position of targets will be computed using weighted Gaussian mixture methods. While computer vision offers many advantages, it has limited performance in poor visibility conditions (e.g., at night, haze, fog or smoke). UWB radar can provide a complementary technology for detecting and tracking humans, particularly in poor visibility or through-wall conditions. As we know, for 2D measurement, one method is the use of at least two receiver antennas. Another method is the use of one mobile radar receiver. This paper tried to investigate the position detection of the stationary human body using the movement of one UWB radar module.

The otitis media has the highest rate of occurrence in 6-36 month after birth, and relatively high rate of occurrence to six years old. It is one of major cause for hearing loss problem because of its high rate of recurrence. The researcher observed at bed that feeding posture and feeding habit at night have some relationship with occurrence of otitis media. I found that medical research in this area was very weak, and it caused her to concentrate her research on the topic. This paper was undertook a retrospective case-control study to find out the relationship between the mode of feeding and the occurrence of otitis media among the otitis media patients and the healthy persons. As the controling groups, the researcher chose fifty eight mothers whose children received the treatment of otitis media(6-36 months after birth) from the pediatrics clinic of two general hospitals in Seoul, as the patient group, and forty five mothers who consulted with their child to well baby clinic at the general hospital and kindergarten in Seoul as the control group. The results of the survey can be summarized as followed : 1. "Otitis media patient group may have more lying posture mothers while feeding than the healthy control group". The first hypothesis is supported by the fact that the children who have lying posture feeding habit mothers are more easily exposed to otitis media than those who have sitting posture feeding habit mothers as the analysis show : $X^2=8.142$, p = .017 2. "Otitis media patient group may have higher rate of sleeping habit with milk bottle on the month at night than the healthy control group does". The second hypothesis was supported by the fact that the patients group has higher rate of expected sleeping habit than the healthy group dose as the analysis show : $X^2=4.35$, p = .037 3. "Otitis media can be found more in the artificial feeding group than in the healthy children group". The hypothesis is rejected by the analysis, $X^2=1.550$, p = .416. Though the hypothesis is not supported by this research, we need to encourage mothers to feed mother's breast milk on the ground that healthy group has mother's milk feeding tendency, and the best food for infants is their mother's milk, and psychological-sociological effects of breast feeding os quite good for children. It will improve the health of infants. It can be summarized as follows : Otitis media is more concerned with posture of feeding and night feeding habits than feeding modes. On the basis of this survey, feeding education problem for mothers of infants need to be developed. In the education, sitting-embracing posture of feeding, mother's breast feeding, and prohibition of children's lying posture feeding at night need to be emphasized.

In general, the patients who transferred to the hospital by 119 rescue service at night go to the emergency room(ER) of general hospital rather than that of their nearby the 1st(clinic) and 2nd(local hospital) hospital. And the hospital is mainly selected not by 119 EMST but by patients or his/her conservators. Therefore we had studied retrospectively with emergency situation diary and medical chart for 697 patients of being transferred to one emergency medical center for 6 months since January 2004, and results are as follows. 1. The 280 patients(42.5%) of being transferred hospital at night by 119 rescue service were not emergency case and their average staying time in hospital was about $7.15{\pm}10.06$ minutes. 2. Transfer time was distributed in each time intervals of 1819, 2021, 2223, and 2401 and patients ratio in each intervals were 15.1%, 17.8%, 16.4%, and 15.2%. 3. In response of ambulance, the average time from the spot to the hospital was $14.53{\pm}9.27min$. and average distance of that was $7.95{\pm}9.21km$. 4. Diseases rather than traffic accidents or traumatic injury were main causes of ambulance calling and its value was 533(76.5%), and accidents were mainly occurred in patients' house and its value was 479(68.7%). 5. In time of transfer by 119 rescue service, hospital was mainly selected by patient/conservator and its value was 648(93.0%). In result. the hospital was selected not by EMST but by patient/conservator. 6. The case that the 1st grade EMT was rode in ambulance was 161(23.1%), and the case that 2nd EMT and emergency team member who educated for emergency were rode in ambulance were 504(72.3%). So the number of the 1st grade EMT was short in fire station of Kwangju metropolitan city than other city. 7. The first aids for patients before reaching hospital were limited to oxygen inhalation, airway control, and BLS for maintaining limbs and spine. So it seems to be a simple patients transfer. Consequently, to establish an efficient emergency medical system, it has been thought that it should be advanced a moderate education and public information about the appropriate use of emergency medical system toward citizen, and also need the hospital selection by the patients categorizing standards for 119 rescue service member, securing the 1st grade EMT, appropriate first-aids education, and securing professional human power in emergency room of the Ist(clinic) and 2nd(local hospital) hospital at night.

It is well known that increased incidences of lung, skin, and bladder cancers are associated with occupational exposure to PAHs. Animal studies show that certain PAHs also can affect the hematopoietic and immune systems and can produce reproductive, neurologic, and developmental effects. As a consequence, several studies have been attempted to investigate the fate of PAHs in atmospheric environment during the past decades. However, there is still a lack of information in regard to the atmospheric concentration of PAHs during the "Bon Fire Night". In this study, twenty-three polycyclic aromatic hydrocarbons and twenty-eight aliphatics were identified and quantified in the $PM_{10}$ and vapour range in Birmingham ($27^{th}$ November 2001-$19^{th}$ January 2004). The measured concentrations of total particulate and vapour (P+V) PAHs were consistently higher at the BROS in both winter and summer. Arithmetic mean total (P+V) PAH concentrations were $51.04{\pm}47.62$ ng $m^{-3}$ and $22.30{\pm}19.18$ ng $m^{-3}$ at the Bristol Road Observatory Site (BROS) and Elms Road Observatory Site (EROS) respectively. In addition arithmetic mean total (P+V) B[a]P concentrations at the BROS were $0.47{\pm}0.39$ ng $m^{-3}$ which exceeded the EPAQS air quality standard of 0.25 ng $m^{-3}$. On the other hand, the arithmetic mean total (P+V) aliphatics were $81.80{\pm}69.58$ ng $m^{-3}$ and $48.00{\pm}35.38$ ng $m^{-3}$ at the BROS and EROS in that order. The lowest average of CPI and $C_{max}$ measured at the BROS supports the idea of traffic emissions being a principle source of SVOCs in an urban atmosphere. The annual trend of PAHs was investigated by using an independent t-test and oneway independent ANOVA analysis. Generally, there is no evidence of a significant decline of heavier MW PAHs from the two data sets, with only Ac, Fl, Ph, An, 2-MePh, 1+9-MePh, Fluo and B[b+j+k]F showing a statistically significant decline (p<0.05). A further attempt for statistical analysis had been conducted by dividing the data set into three groups (i.e. 2000, 2001-2002 and 2003-2004). For lighter MW compounds a significant level of decline was observed by using one-way independent ANOVA analysis. Since the annual mean of $O_3$ measured in Birmingham City Centre from 2001 to 2004 increased significantly (p<0.05), it may be possible to attribute the annul reduction of more volatile PAHs to the enhanced level of annual average $O_3$. By contrast, the heavier MW PAHs measured at the BROS did not show any significant annual reduction, implying the difficulties of 5- and 6-ring PAHs to be subject to photochemical decomposition. The deviation of SVOCs profile measured at the EROS was visually confirmed during the "Bonfire Night" festival closest to the $6^{th}$ November 2003. In this study, the atmospheric PAH concentrations were generally elevated on this day with concentrations of Fl, Ac, B[a]A, B[b+j+k]F, Ind and B[g,h,i]P being particularly high.

During the summer of 1989, the authors carried out the hydroacoustic surverys to investigate the vertical distribution of volume backscattering strength in the East China Sea and simultaneously the biological sampling of the scattering layers by bottom trawling. The echoes from the scattering layers was continuously measured by using a 50 kHz echo sounder during the day and night. A data acquisition system was used to record digitally the envelope of the echoes and the echo integration technique was used to determine the scattering strength proportional to biomass density in each layer. The vertical profiles of volume backscattering strength also were compared with the one of water temperature. The results obtained can be summarized as follows: 1. The vertical profiles of mean volume backscattering strength at day and night suggested that during the night the biggest fish concentrations appeared in the mixed layer above the thermocline and during the day near the bottom. In another profiles where the thermocline was not well developed, peaks in scattering appeared at midwater depths and near the bottom. 2. The maximum values of mean volume backscattering strengths varied from -49.3 dB to -48.0 dB on different regions and at different times of the day and night. 3. Trawl data indicated that the organisms consisting of the scattering layer near the bottom were squid and various species of demersal fishes.
