사회보험 관련법상 특별행정심판제도에 대한 고찰 : 일반행정심판제도와의 통합에 관한 논의를 중심으로

손윤석(Son Youn-Suk) 부산대학교 법학연구소 2012 법학연구 Vol.53 No.1

사회보험수급권과 관련한 행정적 권리구제절차는 크게 행정소송법적 권리구제절차와 행정내부적인 각종 불복제도로 나누어 볼 수 있다. 이 중에서 행정내부적 불복제도는 법원에 의한 소송을 통한 권리구제절차에 비하여 비교적 간단하면서도 신속하고, 권리구제에 있어서 비용을 절감시킬 수 있기 때문에 사회적·경제적 위험에 처해 있는 사회보험수급권자에게는 보다 실효성 있는 권리구제제도로 기능할 수 있다. 그 중에서도 사법절차가 준용되는 행정심판절차는 여타 행정내부적 불복제도에 비하여 공정성과 독립성이 확보되어 법원에 의한 권리구제와 유사한 실효성을 확보할 수 있다는 장점을 가진다. 한편 사회보험관련법률에서는 다양한 권리구제절차를 가지는 바, 이를 소위 말하는 특별행정심판절차로 볼 수 있는지 여부에 관하여는 명확하게 규율하고 있지 않다. 즉 현행 개별 사회보험법률에서는 그 권리구제수단에 있어서 '행정심판'이라는 용어보다는 '이의신청', '심판청구', '심사청구', '재심사청구' 등 다양한 용어를 사용하고 있으면서, 각 절차와 행정쟁송과의 관계에 관한 규정을 명시적으로 두고 있지 않는 경우가 많아서 혼란을 초래하고 있는데, 제도적 관점에서 보면 각 사회보험제도에 있어서 다양한 권리구제절차를 두는 것은 어느 정도 인용될 수 있겠지만, 이러한 불복제도를 활용하여 권리구제를 받아야 하는 국민의 입장에서는 불필요한 혼란만을 가중시킬 우려가 있으므로 이는 개선되는 것이 바람직 할 것이다. 이러한 제도에 대한 개선방안으로 단기적으로는 법률의 규정의 정비를 통하여 불복절차규정의 통일성 확보하고 행정심판 내지 행정소송과의 관계를 명확히 하는 방안이 고려될 수 있지만, 근본적으로는 중앙행정심판위원회에 의한 일반행정심판절차에 통합하는 것이 타당할 것이다. 이를 통하여 최종적으로는 사회보험관련 분쟁을 해결하기 위한 통합 심판기관을 설립하여 심판기능을 이양하는 것이 사회보험관련 분쟁에 대한 통일적 구제책의 마련이라는 큰 틀에서의 제도의 완성을 가능하게 할 것이다. Administrative appeal system has its advantage in many ways such as rapidity, simplicity and inexpensiveness although it is vulnerable to be fair and independent when compared with judicial system. These advantages are more important when it comes to social insurance. However each social security law has separate rules and it makes several problems. First of all, it is unclear that relations between appeal procedures provided in each social security law and administrative appeal process and administrative litigation. Secondly terms of appeal procedure provided in each social security law are different each other. These problems make people who want to use administrative appeal system muddled and make advantages which are admitted in administrative appeal system weak. So we should pursue the way to determine the relations between appeal procedures provided in each social security law and administrative appeal process(especially special administrative appeal process), and unify terms that are used in each social security law. But in the long run it is reasonable to combine these special administrative appeal system with normal administrative system and to transfer to Central administrative appeals commission. That is the way to prevent unnecessary theoretical dispute.

지하철 미세먼지 포집을 위한 기술적 진보

본 연구에서는 지하역사 및 터널에서 발생되는 미세먼지의 현황 및 이를 저감하기 위한 기술의 동향을 조사하였다. 지하역사 및 터널의 미세먼지 농도는 주변 대기 중의 농도보다 높은 것으로 나타났다. 그 구성 성분에 있어서 다양한 중금속 및 발암물질들을 함유하고 있고, Fe의 농도가 가장 높게 나는 것을 알 수 있었다. 지하역사 및 터널의 미세먼지 농도는 주변 대기 농도와 같은 외부 요인뿐만 아니라 열차의 운행 수, 이용 승객수, 환기량과 같은 내부요인도 큰 영향을 미치는 것을 확인할 수 있었다. 현재 지하역사 및 터널의 미세먼지를 저감하기 위해서 다양한 기술 (환기팬, 스크린도어, 자성필터, 소형제트팬, 인공지능 환기시스템 등)들이 연구되고 있으며, 그 기술들은 현장 조건에 맞추어 사용되어야 그 실효성을 극대화시킬 수 있을 것이다.

In this study, we investigated effects of indoor air quality in subway systems according to changes in outdoor air quality. To do this, we analyzed and compared the data measured from five air quality monitoring stations (AQMSs) and four underground subway stations in the central Seoul area. As a result, concentrations of outdoor pollutants (SO₂, CO, NO₂, PM<SUB>10</SUB> and PM<SUB>2.5</SUB>) except for O₃ have been continuously decreasing over the past decade. On the other hand, for levels of pollutants in subway stations, there was a difference by the subway stations and pollutants, but a clear decrease in concentration during the study period could not be confirmed. In addition, as a result of analyzing the correlation between indoor and outdoor pollutant levels, it is judged that gaseous pollutants (NO₂ and CO) came from the outside, but in the case of particulate matter, internal environmental factors were also found to be very large.

기초연금법에 대한 법적 검토

손윤석(Son, Youn-Suk) 한국법학회 2014 법학연구 Vol.56 No.-

2014년 7월 1일부터 시행된 기초연금제도는 시행초기부터 많은 논란에 직면해 있다. 그 가운데 국민기초생활 보장법상 생계급여와의 중복급여제한이라는 문제는 노인빈곤층에게 기초연금제도의 혜택이 사실상 미치지 못하는 결과를 초래하여 문제의 심각성이 부각되고 있다. 이러한 현상이 공공부조법제의 보충성 원칙에서 기인하는 필연적 결과인지 아니면 입법정책상의 문제인지에 대하여 살펴보면 과거 노인복지법상 경로연금으로부터 기초노령연금법상의 기초노령연금에 이르기까지의 다양한 급여가 생활보호법상의 급여 내지는 국민기초생활 보장법상의 급여와 병존해 온 이력을 살펴볼 수 있었다. 또한 보충성의 원리라는 측면에서도 헌법 제34조가 규정하는 인간다운 생활을 할 권리의 실현을 위한 국가의 적극적 개입이라는 관점에서 바라볼 때 국가 등에 의해 이루어지는 급부 간에는 보충성의 원리는 제한적으로 해석되어야 할 것이다. 아울러 기초연금법의 도입취지 및 국민기초생활보장법의 입법 목적 등을 종합적으로 고려하여 기초연금법상의 기초연금급부와 국민기초생활 보장법상의 생계급여는 중복하여 급여가 이루어질 수 있는 방향으로 법규정의 개선이 필요하다. 이를 통해서 기초연금제도가 노인 빈곤층의 실질적 소득보장에 기여하여 우리 사회의 전반적인 사회안전망으로 작용할 수 있도록 발전시켜 나가야 할 것이다. Basic pensions scheme which has issued since 1 July 2014, faces a lot of controversy. Of those, the problem of duplicate coverage restriction of subsistence pay on NATIONAL BASIC LIVING SECURITY ACT and basic pension on BASIC PENSIONS ACT is critical because of the negative effect on the aged poor. But from pension for senior citizens on WELFARE OF THE AGED ACT to Basic Senior Pension on BASIC SENIOR PENSIONS ACT, there had been duplicate coverage between both pays. And in respect of defense of the right to existence on Article 34 of the Constitution, the principle of subsidiarity should be read restrictively. Also The Constitutional Court generally regards the right to receive Public assistance benefits as Abstract right so it must be definitized in the form of law in order to apply to people. Besides in the course of legislation the legislature has broad discretion to be accepted. However discretion which is allowed during implementation and legislation should be interpreted narrowly because the right of existence in the Constitution ought to have aggressive personality and this interpretation makes the right of existence realistic and effective fundamental right. Lastly, considering legislative intent of BASIC PENSIONS ACT and NATIONAL BASIC LIVING SECURITY ACT, provisions need to be revised to improve poverty reduction of the aged poor. That way, Basic pensions scheme should be advanced to perform the role of social safety network.

In order to investigate the NVOC (Natural Volatile Organic Compound) emissions from White Oak, the emission rates of isoprene were measured according to season, weather conditions, and the age of the tree. The analysis of seasonal emission rates showed that the emission rates were the highest during summer followed by spring and fall. The emission rates during summer were found to be nearly 8 times greater than those during fall. In addition, it was observed that the emission rates of isoprene depends on PAR and temperature. Moreover, the effect of age on the emission rates was studied, and the White Oak in the age range of 21~30 had higher emission rates than that in the range of 41~50. Accordingly, the current result indicates that the isoprene emissions are affected by both meteorological parameter and the age of a tree.

유효광합성량 (PAR)의 증가에 따른 BVOCs 배출 특성 변화

In this study, emission rates (ER) of biogenic volatile organic compounds (BVOCs) were measured by varying levels of photosynthetically active radiation (PAR). An appropriate plan for ozone reduction according to increasing ecology area ratio in future metropolitan areas was suggested. Several trees were selected as representative tree species in urban areas. Emission rates and composition ratios of monoterpene and isoprene emitted from these trees were estimated and compared. As a result, it was found that emission rates of BVOCs were considerably different depending on tree species. Especially, BVOCs emitted from Platanus orientalis and Quercus mongolica could significantly affect ozone increase in the metropolitan area, because the emission rates were several thousands to ten thousand times higher than those emitted from Zelkova serrata and Prunus serrulata. Furthermore, it was observed that emission rates of BVOCs by species increased maximum up to 10 times when PAR, which has close relations with temperature, rose. It was concluded that tree species such as Zelkova serrata et al., was appropriate for metropolitan areas since the species has low ozone potential and good landscape. Suppose this type of trees are planted on purpose in the urban areas, better ambient air quality will be promised in the future.

국내 초등학교 내 입자상 물질 및 영향 요인

손윤석(Youn-Suk Son) 한국대기환경학회 2020 한국대기환경학회지 Vol.36 No.2

Children spend a lot of time of day in school and are more sensitive to contamination of indoor air than adults. This study reviewed the level of particulate matter (PM) and influencing factors in elementary schools in Korea (e.g., occupant density, classroom type, sampling height, building year and indoor and outdoor environment factors) and suggested methods and future research directions to reduce particulate matter. To this end, we reviewed domestic and international papers published since 2006. As a result, a coarse particle in a classroom (PM<SUB>2.5</SUB> - PM<SUB>10</SUB>) is mainly formed by internal sources, whereas PM<SUB>2.5</SUB> (PM<2.5 ㎛ in aerodynamic diameter) is caused by external sources. The number and activities of student in a classroom were positively correlated with PM<SUB>10</SUB>(PM <10 ㎛ in aerodynamic diameter) levels, but PM<SUB>2.5</SUB> levels did not show a clear tendency. We found that general classrooms have a slightly higher PM concentration than the special rooms (computer room and laboratory). In addition, some studies showed that the humidity and CO₂ in the classroom had a positive correlation with PM<SUB>2.5</SUB>. In addition, PM<SUB>2.5</SUB> was found to be more affected by the air quality around the school than PM<SUB>10</SUB>. When compared previous studies measured at school-related facilities in Korea to date, the concentrations of PM<SUB>10</SUB> were mostly satisfied with the criteria at the time of measurement. However, when compared with the newly revised concentration of “School Health Act” (75 ㎍/㎥), a significant number of schools were found to exceed the standard. Therefore, measures to improve indoor air quality in schools are urgently needed.

국민기초생활보장법상 부양능력미약제도에 관한 법적 고찰

손윤석 ( Youn Suk Son ) 한국사회보장학회 2012 사회보장연구 Vol.28 No.2

The purpose of this paper is to reconsider the concept of marginal ability to support and analyze the problems of this concept. Many researchers argue that there have been many problems such as exclusion from the right of receiving national basic livelihood pay and the concept of marginal ability to support should be abolished. But there are also many profitable characteristics in this concept. So This system should be supplemented rather than abrogated. Reinforcement of investigation and defining obligation of advanced pay could be involved in specific plan. By improving this system, the right of receiving national basic livelihood pay can be broadened than ever before.

In this study, sampling and analysis was carried out for 13 compounds, in order to investigate the odorous compound emissions from landfill stacks and surrounding ambient air. These results revealed that concentration of hydrogen sulfide was 0.13~0.66 ppb in the ambient air. Also, concentrations of hydrogen sulfide (151~358 ppm) were the highest value in odorous sulfur compounds from landfill stacks. In case of VOC, toluene was obtained the highest out of volatile organic compounds. It was found that the concentrations of hydrogen sulfide near the landfill was higher than that inside city such as Seoul although it was located in a rural area. The result was due to the effect of hydrogen sulfide emitted from landfill stacks.
