Objectives : The purpose of this study were to evaluate the effects of oriental medical therapy on obesity and different effects according to Body Mass Index(BMI), menopause, obesity treatment experience, age, treatment period in patients. Methods : 46 patients were treated from November 2011 to April 2012 in Oriental Obesity Center, Dong-eui Medical Center. They were measured change of body compositions by bioelectrical impedance analysis every 2~3 weeks and 27 patients out of 46 were checked body compositions every 2 weeks. 46 and 27 patients were divided into two or three groups according to BMI, menopause, obesity treatment experience, age, treatment period. We compared before and after treatment body compositions. Results : Body compositions, except edema index were significantly reduced. Abdominal Visceral Fat(AVF) was significantly reduced in Obese group. Body Weight(BW), BMI, Body Fat(BF), Body Fat Percetage(BFP), Abdominal Visceral Fat Level(AVFL), Abdominal Visceral Fat(AVF), Abdominal Subcutaneous Fat(ASF) were significantly reduced in non-menopause group(43 female patients). But in 26 female patients out of 27, there were no significantly differences between groups in menopause. There were no significantly differences between groups in obesity treatment experience. But in 27 patients, BMI and AVF were significantly reduced in non-experience group and AVFL was significantly reduced in experience group. BW, BMI, BF, BFP, VAF, ASF were significantly reduced in younger age group. But in 27 patients, BW and Muscle were significantly reduced in younger age group. BMI, BF, BFP, Edema, AFVL, Abdominal Visceral Fat Area(AVFA), AVF, ASF were significantly reduced in longer treatment period group. Conclusion : The BF, BMI, BF, BFP, Muscle, AVFL, AVFA, AVF, ASF were almost decreased significantly. It resulted that the effects of oriental medical therapy in obesity was positive. And it was meaningful study to know about different effects between groups.

Background: In South Korea, African swine fever virus (ASFV) has spread among wild boars through Gangwon-do to Dangyang-gun, Chungcheongbuk-do on the southern border of Gangwon-do. To prevent the spread of ASFV to African swine fever (ASF)-free areas, it is necessary to identify areas with a high probability of finding ASFV-infected carcasses and to reduce the density of wild boars in those areas. In this study, we described the propagation trend of ASFV among wild boars, constructed the habitat suitability maps for ASFV-infected carcasses, and suggested areas with a high probability of finding ASFV-infected carcasses and an important route of ASFV transmission. Results: Despite the active quarantine policies in Korea to prevent the spread of ASFV through wild boars, there was no significant difference in the monthly average of number of ASFV-infected carcasses observed between 2020 and 2021. The ASFV-infected carcasses were found more in winter and spring (January to April). Since the first ASF outbreak in wild boars on October 2, 2019, the maximum width of ASFV-infected carcass distribution area was 222.7 km for about 26 months till November 20, 2021. The habitat suitability map, based on GPS coordinates of ASFV-infected wild boar carcasses, shows that highly detectable areas of ASFV-infected carcasses were sporadically dispersed in western and southwestern parts of Gangwon-do, and ranged from north to south of the province along the Baekdudaegan Mountains, whereas poorly detectable areas ranged along the north to the south in the middle parts of the province. Conclusions: Our suitability model, based on the GPS coordinates of ASFV-infected carcasses, identifies potential habitats where ASFV-infected carcasses are likely to be found and ponential routes where ASFV is likely to spread. Among ASF-free areas, the areas with high suitability predicted in this study should be given priority as survey areas to find ASFV-infected carcasses and hunting areas to reduce wild boar populations.

This paper presents an ASF (Aluminum Space Frame) BIW optimal design, which minimizes the weight and satisfies multi-disciplinary constraints such as the static stiffness, vibration characteristics, low-speed crash, high-speed crash and occupant protection. As only one cycle CPU time for all the analyses is 12 hours, the ASF design having 11-design variable is a large scaled problem. In this study, ISCD-II and conservative least square fitting method is used for efficient RSM modeling. Then, ALM method is used to solve the approximate optimization problem. The approximate optimum is sequentially added to remodel the RSM. The proposed optimization method used only 20 analyses to solve the 11-design variable design problem. Also, the optimal design can reduce the] $15\%$ of total weight while satisfying all of the multi-disciplinary design constraints.

This study was conducted to investigate the effects of wild ginseng complex (WGC) pharmacopuncture combined with hyperthermia on abdominal obesity in post-menopause women. Two post-menopausal women were treated 5 times in 2 weeks with WGC pharmacopuncture on abdominal acupoints and 30 minutes of hyperthermia on abdominal area. Before treatment and after 5 treatments were finished, body weight (BW), body mass index (BMI), body fat ratio, waist circumference (WC), waist hip ratio, thickness of abdominal subcutaneous fat (ASF) were measured. In case 1, BW, BMI, WC, and ASF were reduced by 0.6 kg, $0.2kg/m^2$, 6 cm, and 18 mm respectively. In case 2, BW, BMI, WC, and ASF were reduced by 0.4 kg, $0.17kg/m^2$, 4.6 cm, and 12 mm respectively. This suggest that combined therapy of WGC pharmacopuncture and hyperthermia might be an effective treatment for abdominal obesity in post menopause women.

A new routing computer model for the symmetric compound channel called the ASFMCS (Apparent Shear Force Muskingum-Cung Method in Symmetry) is developed. The Muskingum-Cunge routing method is adapted. The Apparent Shear Force(ASF) between the deep main channel and shallow floodplain flow is introduced while the flow is routed. The nonlinear parameter method is applied. The temporal and spatial increments are varied according to the flow rate. The adaptation of above schemes is tested against the routed hydrographs using the DAMBRK model. The results of general routing practice of Muskingum-Cunge Method (GFMC) are also compared with those of the above two models. The results of the new model match remarkably well with those of DAMBRK. The routed hydrographs show smooth variation from the inflow boundary condition without any distortions caused by the difference of cross-section shape. However, the results of GPMC, showing earlier rising and falling of routed hydrograph, have considerable differences from those of the ASFMCS and DAMBRK.

본 연구에서는 비파괴적 분석 기법인 각분해 X-선 광전자 분광기(Angle-Resolved X-ray Photoelectron Spectros-copy)를 이용하여 GaAs 표면 자연 산화막의 깊이에 따른 화학적 결합 상태 및 조성 분석을 수행하였다. GaAs의 벽개면 및 Ar이온으로 식각된 면을 기준시료로 하여 각 원자의 광전자 강도(intensity)를 보정해주는 인자인 ASF(atomic sensitivity factor)의 최적값을 구하였다. 이륙각에 따라 발생되어지는 각 원소의 피이크 분해와 정확한 ASF의 보정을 통한 각 원소의 실험적인 결과를 이용하여 깊이 방향으로의 조성 분포 모델을 세웠으며, 이론적인 강도와의 상호비교로부터 표면 오염층의 구조는 표면으로부터 탄소층, Ga-oxide와 As-oxide로 이루어진 oxides층, As-As결합의 elemental As층 및 GaAs기판의 순으로 존재함을 알 수 있었다. 또한 GaAs 표면에 존재하는 오염층은 35.8$\pm$3.3 $\AA$이었다. 또한 위 결과로부터 분석깊이 영역에서 원자수의 비로써 정의되는 의미로서의 실질조성을 구하였는데 단지 특정 이륙각에 따라 일반적인 ASF로 보정된 표면조성 결과는 표면 상태를 명확히 표현해주지 못함을 확인할 수 있었다.

There are three essential components of eLoran: dLoran, data map of ASF, and the Loran data channel. Particularly, dLoran improves navigation accuracy, which is the core technology of eLoran systems. The requirement of HEA's absolute accuracy, less than 20 meters, can be satisfied via dLoran measurements and their corrections. In this study, dLoran measurements using the Pohang Loran-C (9930M) station signal were conducted at Yeongil Bay. We established a dLoran reference station at Homigot Management Office for navigation aids within the Bay. We estimated the effectiveness of the dLoran between the reference site (Homigot Management Office) and a test site (Heunghwan beach) by measuring TOAs. We verified that the TOA data measured at these two regions were highly correlated. The temporal differences in the data between the dLoran reference station and test site were about 10~30 ns per day, which is equivalent to a ranging error of 3~9 m. This result shows that eLoran can meet the requirement of 8~20 meters position accuracy for maritime HEA by correcting the ASF at the user's receiver.

This article reviews previous literature on the metaverse and attempts to provide a refined definition for this phenomenon. Metaverse has recently been in the spotlight among discussions by the industry and the media while a consensus on the exact definition of metaverse is yet to be determined. Since Neal Stephenson first coined the term metaverse in his novel "Snow Crash" in 1992, the Acceleration Studies Foundation (ASF) was the first to analyze the concept of metaverse in 2007. While ASF's effort did not receive much spotlight it may have deserved, metaverse gained much attention in the fall of 2020 when NVIDIA announced its real-time simulation and collaboration platform for 3D production named "Omniverse" as a next-generation alternative for the Internet along with Roblox defining its service as metaverse during its IPO. Since then, metaverse has been commonly recognized as a world where we can cross over reality and virtuality. Based on the two axes and four scenarios proposed by the ASF, we review the literature across four realms as follows - virtual reality, mirror world, augmented reality, and lifelogging. Then, we examine the issues with the existing definition of metaverse and propose an alternative explanation by focusing on human behavior and user experience. Finally, we reassess the concept of metaverse and incorporate human communication, reality-based and virtual-based activities, and eXtended reality as elements to properly define metaverse.
