해수면 온도에 대한 구름복사 강제력의 지역 의존도가 조사되었다. 이 조사는 경년 변동과 계절 시간규모에 대해서 각각 조사되었다. 적도 동태평양에서 경년 변동의 경우 해수면 온도가 1˚C 증가할 때 순 구름복사 강제력은 약 3Wm-2가 증가하였으며, 계절변동이 포함된 경우 약 3.5Wm-2가 증가하는 것으로 나타났다. 반면 열대 해양전체에서 경년 변동의 경우 해수면 온도가 1˚C 증가할 때 순 구름복사 강제력은 1.5Wm-2 감소하였으나, 계절변동이 포함된 경우 약 2.9Wm-2로 증가하였다. 따라서 해수면 온도에 대한 구름복사 강제력의 의존도는 적도 동태평양에서 열대 해양으로 넓어질수록 경년 변동에 의해 영향에서 계절변동에 의한 영향이 더 지배적으로 작용한다. 계절 변동이 포함된 경우 해역에 관계없이 해수면온도가 1˚C 증가할 때, 순 구름복사 강제력은 약 2∼3Wm-2 증가하였다. 이러한 결과는 해수면 온도의 경년 변동이 뚜렷한 적도 동태평양에서는 경년 변동에 의한 구름복사 강제력이 대기를 가열하는 반면, 열대 해양 전체에서는 계절변동에 의한 구름복사 강제력이 대기를 가열한다는 것을 의미한다.

Work-related injurieshave become the issue in the twentieth century. Musculoskeletal disorders are the most common work-related injuriesand the most frequent from of work-related i11-health (more than 50％ of total work-related injuries (BLS 1990)). The workers at copy shops have complained of pain in their back, legs, and shoulders. Most of them work for more than 8 hours a day. They have claimed that their pains were associated with repetitive and continuous work over a long term. The purpose of this research is to suggest an ergonomically comfortable redesign of the copy machine. This study was performed by conducting a survey of copy shop workers who have complained of job-related physical pain, and analyzing their working postures. The copy machine was ergonomically modified to reduce the workers' pain. The VIS10N 3000 software was used to analyze the posture. The analysis showed significant difference in the ranges of back and neck motion (p<0.05).

We have developed a Monte Carlo code, which solves the problem of radiative transfer in anisotropically scattering atmosphere. The radiative code is flexible in handlings of the system geometry, the distribution of scattering particles, and the source-particle geometry. This code treats the case of highly forward throwing scattering. As performance tests, we have compared the result of Monte Carlo calculations with that of Quasi-Diffusion method for a spherically symmetric cloud model.

It has been recognized that the morphologies of the SNRs from the radio observation are "barrel shaped". To interpret the mechanism of the radiation and the physical state of the environments, we have analytically calculated the dynamical structure of the interacting region in the case where the ejectum has a steep power-law density profile(ρ∼r−n ρ∼r−n ) and the ambient medium has a shallow power-law density profile(ρ∼r−s ρ∼r−s ), assuming that the cosmic rays are isotropically accelerated in the shock wave and the magnetic fields are very weak. The calculated synchrotron radio maps show that the emission from the equator is intense and the emissions from the central and polar regions are less intense. Also the thicknesses of the shell are strongly dependent on s and weakly on n. The azimuthal intensity ratio α α increases as the efficiency of the cosmic ray acceleration increases and s decreases. We compared the results with the morphology of the SNR A. D. 1006(type I SNR). It does agree with the case of s = 0, w = 0.3 - 0.5. This value for w is consistent with the results by Eichler(1979). It provides us the evidence of the cosmic ray acceleration in the shock wave.

The effective temperatures and the bolometric corrections of 0-G type stars and derived from de-reddened monochrometric and integrated fluxes obtained by absolute spectrophotometry on the ground and satellite (IUE, 1985, OAO : Code and Meade, 1979 ; Code et al., 1980), using the method simillar to that of Code et al.(1976) with the LTE model atmospheres by Kurucz(1979). The effective temperatures and the bolometric corrections derived from this work are found to be in good agreement with those of Code et al. (1976), Morossi and Malagnini (1985), Malagnini et al. (1985) etc., being significant for basic astrophysical quantities.

Even after the Article 237–2[Article 237–2 (Reproduced Documents, etc.) For the crimes as prescribed in this Chapter, any copies of documents or drawings reproduced using the electronic reproduction machines, facsimile telegraphs or other similar apparatus, shall be considered as document or drawing.] of the Penal Code was created, the world has changed and also shown a technological progress at a pace that is difficult to follow, and as a matter of fact, it is being questioned whether it will be able to engage or replicate all duplication techniques. It is said that Article 237–2 is a legislative error to be abolished and all copying can not be counterfeited by legislative measures of ‘copying is conterfeiting.’ It is also strongly voiced to point out the supreme attitude of legal interpretation of the Supreme Court, which does not properly reflect the reality of computer–based document processing and use, such as changing the image on a computer screen. The Supreme Court’s recent ruling, which is the subject of a critical analysis of this paper, is drawing attention to the issue again. The purpose of this article is to clarify the current law and the interpretation of the law of the Supreme Court, and examine the argument of the interpretation by comparing and examining several precedents showing various types of behavior among the precedents of the Supreme Court up to now.

The spatial and temporal variations of CO2 concentrations and radiative forcing (RF) due to CO2 were examined at urban center (Yeon-dong) during 2010-2015 and background sites (Gosan) during 2010-2014 on Jeju Island. The RF at the two sites was estimated based on a simplified expression for calculating RF for the study period. Overall, annual mean CO2 concentrations at the Yeon-dong and Gosan sites have gradually increased, and the concentrations were higher at Yeon-dong (401-422 ppm) than at Gosan (398-404 ppm). The maximum CO2 concentrations at the two sites were observed in winter or spring, followed by fall and summer, with higher concentrations at Yeon-dong. The RF at Yeon-dong (annual mean of up to 0.70 W/m2 in 2015) was higher than that at Gosan (up to 0.46 W/m2 in 2014), possibly because of higher CO2 concentrations at Yeon-dong resulting from population growth and human activities (e.g., fossil fuel combustion). The highest monthly mean RFs at Yeon-dong (approximately 0.92 W/m2) and Gosan (0.52 W/m2) were observed in spring 2015 (Yeon-dong) and spring 2013 (Gosan), whereas the lowest RFs (0.17 and 0.31 W/m2, respectively) in fall 2011 (Yeon-dong) and summer in 2012 (Gosan).

The shortwave aerosol direct radiative forcing (SWARF) was analyzed using the Clouds and Earth’s Radiant Energy System (CERES) data in the East Asian region from 2001 to 2010. In the Yellow Sea and the Korean Peninsula, located in the leeward side of China, significantly negative high SWARF at the top of atmosphere (TOA) occurs due to the long-range transport of anthropogenic (e.g. sulphate) and natural aerosols (e.g. mineral dust) from the East Asian continent. Conversely, eastern China has much higher levels of SWARF at the surface (SFC) due to anthropogenically emitted aerosol than in the Yellow Sea and the Korean Peninsula. Since the radiative forcing of aerosols in the atmosphere are different in type, aerosol types were classified into sea salt+sulphate, smoke, sulphate and dust by using satellite data. The analysis on the SWARF by the classified aerosol types indicated that sulphate occupies a predominant portion of the atmosphere in the Yellow Sea and the Korean Peninsula in the summer. In particular, the annual averages of the summer TOA SWARF increased in the Yellow Sea and the Korean Peninsula from 2001 to 2010.

방출장파복사량은 수치예보모형, 수문모형, 증발산 등에 사용되는 인자로 지구의 에너지 균형을 이해하는데 필수적이다. 현재 국내외에서는 이를 정확하게 관측하기가 어려우며, 또한 공간적인 제약이 따른다. 따라서, 본 연구에서는 원격탐사기술을 적용함으로써 지상관측의 단점을 보완하기 위해 정지궤도 위성인 Communication, Ocean and Meteorological Satellite (COMS)를 사용하여 방출장파복사량(Outgoing Longwave Radiation, Rlu)를 계산하였다. 이 자료의 검증을 위해 유량조사사업단에서 운영·관리하는 청미천/설마천 Flux Tower의 자료를 사용하여 계산된 Rlu와 MODIS 위성자료를 사용하여 계산된 Rlu를 비교 및 검증하였다. 전반적으로 COMS의 자료가 높은 상관계수를 나타내어 COMS의 사용가능성을 보여주었다. 이러한 결과를 바탕으로 향후 COMS를 이용한 증발산 산정 연구를 할 계획이다.

최근 들어 기후변화로 인해 물과 에너지 순환에 관한 정확한 이해가 요구되고 있다. 현재 미기상학적 플럭스 타워 네트워크는 수문학적, 생태학적 분석에 있어서 주춧돌역할을 하고 있다. 하지만 플럭스 타워의 에디공분산 방법을 활용한 잠열 플럭스 측정은 여러 가정사항에 따른 시스템적 오류를 내포하고 있고 이에 따라 과소평가된 잠열 플럭스 원시자료의 보정이 필요하다. 몇몇의 보정방법 중 보엔비를 활용한 방법이 가장 유용한 방법 중 하나로서 여기에는 플럭스타워에서 측정한 순 복사에너지 및 기타 플럭스(현열, 지열) 등이 요구되며 이러한 자료에 대한 정확한 측정 및 검증이 필요하다. 본 연구에서는 설마천, 청미천 유역의 플럭스타워에서 측정된 순 복사에너지를 검증하기 위해 두 가지 형태의 이론적으로 계산된 순 복사에너지와의 비교검증을 실시하였다-(1) FAO 56 기반의 일평균 순 복사에너지 (2) Bastiaansen (1995)가 제안한 순간 순 복사에너지. 본 연구의 결과는 플럭스타워에서 측정된 순 복사에너지는 이론적으로 계산된 순 복사에너지와 상당히 비슷한 경향성을 보인다는 것을 제시했다. 또한, 측정된 순 복사에너지를 이용하여 관측된 잠열플럭스를 보엔비 보정방법에 적용시킨 결과 에너지수지에 더욱 부합하는 것을 알 수 있었다.

Any copies of documents or drawings reproduced using the electronic reproduction machines, facsimile telegraphs or other similar apparatus should be considered as document or drawing in Criminal Law. But it seems not to coincide with the concept of copy and meaning of duplicated document. Especially as far as media records, such as another person's electromagnetic records are concerned, there are many unsettled problems. The interests protected by law of crime concerning Documents are public credibility. so I think that constituent elements of a crime have to be interpreted by means of improving public credibility. That's to say that we should connect with crime-concerning condition and something protected by criminal law. but Supreme court didn't accept copies of documents concerning copy from documents to electromagnetic records in 2007do7480 and 2008do 5200. Any copies of documents should be protected because they establish the existence of original documents. that's reason that Any copies of documents reproduced using the electronic reproduction machines, facsimile telegraphs or other similar apparatus should be considered as document or drawing in Criminal Law. So someone would scan the documents and make new electromagnetic reproduction records of the scanned document, we must regard that as duplicated documents.

Many recent studies have concentrated upon the radiative effects of atmospheric aerosols. Though their scattering and absorption of radiation, aerosols can also induce some other important environment effects. In this study, new radiation code and aerosol data within Atmosphere General Circulation Model (AGCM) is used to assess the aerosol radiative forcing and to analyze relative climate effects. The new Kangnung National University AGCM Stratospheric-15 (KNU AGCM ST15) was integrated by using two sets of radiative effect of aerosols : CTRL as not a radiative effect of aerosols and AERO as a radiative effect of aerosols. Two cases show the difference of net shortwave radiation budget at top-of-atmosphere (TOA) is found to be about -3.4 Wm-2, at the surface (SFC) is about -5.6 Wm-2. Consequently the mean atmospheric absorption due to aerosol layer in global is about 2.2 Wm-2. This result confirms the existence of a negative forcing due to the direct effect of aerosols at the surface and TOA in global annual mean. In addition, it is found that cooling over at the surface air temperature due to radiative effect of aerosols is about 0.17 ℃. It is estimated that radiative forcing of the net upward longwave radiation taken as the indirect effect of aerosol is much smaller than that of the direct effect as there is about 0.2 Wm-2 of positive forcing both at TOA and at SFC. From this study, It made an accurate estimation of considering effect of aerosols that is negative effect. This may slow the rate of projected global warming during the 21st century.

In this study, the Slab Ocean Model (SOM) is coupled with an Atmospheric General Circulation Model (AGCM) which developed in University of Kangnung based on the land surface model of Biosphere-Atmosphere Transfer Scheme (BATS). The purposes of this study are to understand radiative role of clouds considering of the atmospheric feedback, and to compare the Clouds Radiative Forcing (CRF) come from the analyses using the clear-cloud sky method and CGCM. The new CGCM was integrated by using two sets of the clouds with radiative role (EXP-A) and without radiative role (EXP-B). Clouds in this two cases show the negative effect -26.0 Wm-2 of difference of radiation budget at top of atmosphere (TOA). The annual global means radiation budget of this simulation at TOA is larger than the estimations (-17.0 Wm-2) came from Earth Radiation Budget Experiment (ERBE). The work showed the surface negative effect with -18.6 Wm-2 in the two different simulations of CRF. Otherwise, sensible heat flux in the simulation shows a great contribution with positive forcing of +24.4 Wm-2. It is found that cooling effect to the surface temperature due to radiative role of clouds is about 7.5℃. From this study it could make an accurate of the different CRF estimation considering either feedback of EXP-B or not EXP-A under clear-sky and cloud-sky conditions respectively at TOA. This result clearly shows its difference of CRF -11.1 Wm-2.
