Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

Background: Solar urticaria (SU) is an uncommon type of photodermatoses characterized by erythematous wheal with pruritus after sunlight exposure, which shows a female predominance. Only a few studies to analyze the clinical features of SU were reported in Asia. Objectives: We aimed to analyze the clinical and photobiological characteristics of SU in Korea. Methods: We retrospectively investigated the medical records of patients with SU who visited the department of dermatology, Konkuk university medical center from January 2005 to January 2020. Results: Of a total of 44 patients, 36 (81.8%) were male and 8 (18.2%) were female. The mean age at onset was 17.6 years (range, 5-47) and the mean threshold time was 19.7 minutes. Among 32 patients who underwent phototesting, the action spectrum most commonly implicated was ultraviolet (UV) A only in 12 (37.5%), and then visible light (415nm) only was responsible for SU in 8 (25.0%). Three patients (9.4%) were induced by both UVA and visible light (415nm). Even 4 patients (12.5%) were triggered by only natural sunlight. Serum immunoglobulin E levels were measured in 33 patients, and 17 (51.5%) showed values higher than normal. The treatment most widely used were oral antihistamine (43.2%), followed by phototherapy (13.6%). Conclusion: SU is a rare photodermatosis in Korea, which shows a male preponderance. In this study, UVA and visible light (415nm) were predominant action spectrum of SU.

Recently, as housing supply is going on too high-rise apartment, it's pointed out an urban environment is not a variety of forms. The purpose of this research is to propose the new methods of supplying an urban co-operative housing premising that the common house of the city is not an ordinary collective housing like the present but a form that accepts a variety of life of residents. The applying probability of co-op housing is investigated by using a questionnaire whether house demanders satisfy themselves or not and the rest of researching contents quotes from data recorded a thesis, statistical data and periodicals by documentary research. As the results of a questionnaire, it was evaluated that 75 percents of respondent had affirmative opinions. If co-operative housing is bring in our country, it is expected that it can alternate potential demand successfully which is not equal to the existing task.

Digital high resolution cameras are widely available. and are increasingly use in digital close-range photogrammetry. And photogrammetry instruments are developing rapidly and the precision is improving continuously. The building of 3D terrains of high precision are possible and the calculation of the areas or the earthwork volumes have high precision due to the development of the technique of the spatial information system using computer. Using the digital camera which has capacity of keeping numerical value by itself and easy carrying. we analyze the positioning error according to various change of photographing condition. Also we try to find a effective method of acquiring basis data for 3D monitoring of high-accuracy in pixel degree through digital close-range photogrammetry with bundle adjustment for local terrain model generation and 3D embodiment of tumulus. In the study is about to efficient analysis of digital information data for conservation of cultural properties.

This study conducted for analyze the process of physiological variation during shooting, and produce the basic data for training prescription to the performance improvement in Air Rifle Shooting, 9 Elite Rifle shooters )College 3, High School 3, Middle School 3) in GangWeon province were tested the physiological parameter which are Electrocardiograph(E.C.G), Heart-rate(H.R), Respiratory pattern, and Trigger time by polygraph system 8 channel from Sept. 1st to Sept. 10th, 1985. Analyzed experimental results are as follows; 1. Firing at T-P wave in E.C.G, 77.68bpm in H.R)16.68% by resulting H.R), the deep size of inspiration-expiration was low, and 8.34 sec of trigger interval were appeared when the shooter acquired high score. 2. The most effective factor among physiological parameters for excellent shooting score is the inspiratory volume with decresc breathing pattern. 3. Shooting performances correlated with stability and static-dynamic balance, but flexibility effected on negative correlation.

A valve spring retainer is a small disc and located at intake and exhaust valve stem of engine. The retainer supports a valve spring and transmits spring force to a valve. Force is applied to the retainer repeatedly by a rocker arm. Durability of the retainer is an important factor of performance. Weight of retainer affect dynamic performance of engine. Therefore, optimal strength and weight of the retainer design are needed. In this study, stress distribution and fracture load of retainer were analyzed by using FEM to design optimal strength and weight. Static load test was simulated by using commercial FEM code DEFORM-3D. Shapes of the retainer to reduce weight were designed and analyzed to verify validity of it. Simulated results and experimental ones were compared

A low loss frequency doubler operated on low power for the RFID harmonic tags is presented. Using the excellent nonlinear characteristics of the Schottky barrier diode and proper matching networks between the diode and ports, the low conversion loss of the harmonic tag is accomplished. This doubler could be used to increase the detectable distance of the conventional RFID system adopted harmonic tags.

Background : Acute bacterial prostatitis is an uncommon male urinary tract infection that is the result of severe prostatic infection mainly by gram-negative bacteria. We conducted a retrospective study to report clinical outcomes of patients with acute bacterial prostatitis. Materials and Methods : The clinical records of 49 patients diagnosed with acute bacterial prostatitis were reviewed retrospectively and patients' symptoms, investigations, and treatments were analyzed. Results : All patients presented with fever and voiding symptoms. Some patients (22.4%) had a history of prior manipulation of the lower urinary tract including transrectal prostate biopsy. Urine cultures were positive for 51% of the patients. The most common pathogen was Escherichia coli (60%), followed by Pseudomonas aeruginosa (20%) and Staphylococcus aureus (12%). The ciprofloxacin susceptibility against E. coli was 80%. All patients were treated with parenteral antibiotics in the hospital followed by oral antibiotics for average of three weeks. The major drugs used for empirical treatment were cephalosporins, aminoglycosides, and fluoroquinolones. Prostatic abscess was found in two (4.1%) Patients and chronic pelvic pain syndrome developed in six (12.2%) patients during follow-up. Conclusion : The currently used empirical antibiotics were mostly effective in the treatment of acute bacterial prostatitis. Continuous monitoring on antimicrobial susceptibility of acute bacterial prostatitis was necessary for providing proper treatment guideline.
