The present study attempted to find a direction forward for the legal services market in an era of creative innovation by reviewing the issue of conflict between online legal services platforms such as ‘LawTalk’ and the world of legal professions. Specifically, the study extracts and takes as analysis tools similar arguments from the cases of ‘TADA’, ‘Uber’, and ‘Airbnb’ and then comparatively examines overseas cases concerning legal services platforms. The essence of the argument surrounding platforms lies in whether platform services are simply ‘network services that provide a place connecting suppliers and consumers’ or whether platforms should be viewed as providing ‘substantive services such as transportation, lodgings, and legal defense’. The European Court of Justice(ECJ) states that a platform is exempt from existing regulations if the platform service is separable from offline services but subject to regulations if the platform and offline services are combined as one to form an overall service. Accordingly, Uber’s transportation intermediary service was viewed as a transportation service in substance(subject to regulations), while Airbnb’s lodgings intermediary service was viewed as an information society service(exempt from regulations). If that’s the case, are legal service platforms like LawTalk illegal? The issue is whether the LawTalk service falls under ‘acts of connecting or mediating between an attorney and a client or referring an attorney’, prohibited by the Attorney-at-law Act. Because LawTalk is an advertising platform that receives fixed advertising rates for providing an online advertising space, it is difficult to assess its services as ‘direct acts of connection’ prohibited by the Attorney-at-law Act. Moreover, attorneys must be allowed to promote themselves to unspecified persons and entice clients by paying advertising fees, and the platform business to achieve these ends must be allowed as well. However, an advertising platform is not allowed to exploit attorneys in the process of promoting the platform itself or make the mistaken impression that it is affiliated to an attorney, nor is the platform allowed to do advertisements with attorney contacts listed, with the ad exposed across an entire page. The ECJ’s ruling is applied as a standard in addition to interpretations of current law. The fact that attorneys can use traditional methods(mediums such as newspapers, magazines, broadcasts, and computer communications) rather than LawTalk for ads and searches, the fact that LawTalk does not prescribe legal fees for attorneys or an upper limit, and the fact that it is difficult to view LawTalk as exercising direct control over the signing of delegation contracts or the quality of legal defense render LawTalk services assessed as not the referral of particular attorneys and independent from actual legal defense services. It is more than necessary to listen to the criticism that platforms inundate the market with free ads or unfair cheap ads in the process of attorneys accepting cases, threatening the market order of fair case acceptance and attorney ethics, and that increasing reliance on platforms make attorneys beholden to these platforms. However, when considering the trend of the times involving legal tech and demand on the part of legal consumers, it is not desirable to completely ban platform services on the grounds of excessively strict interpretations. Moreover, advertising platforms, as opposed to intermediary platforms, are allowed overseas. If platforms provide a place connecting attorneys and clients rather than display an appearance of subordinating attorneys using their market-dominating position, then such a business model should be allowed. At present, adequate regulations that block the adverse effects of platforms while strengthening their positive effects are necessary, along with clear guidelines.

선박의 피로 손상 해석에는 운항적인 요소를 고려한 매개 변수들을 포함하고 있다. 이러한 운항적인 변수들 때문에 설계 단계 에서 예측하는 피로 손상도와 실제 운항 조건을 고려한 피로 손상도간의 차이가 발생한다. 마찬가지로 피로 해석에서 적재 하중 조건을 고려할 때 실제 컨테이너선은 다양한 적재 상태가 존재하지만 설계 단계에서 대표 하중 조건을 선택하여 피로 손상도를 계산한다. 실제 하중 조건과 설계시 하중 조건을 적용하였을 때 피로 손상 계산 결과의 차이가 예상됨에도 불구하고 컨테이너선의 하중 조건에 따른 피 로 손상 기여도에 관한 연구는 거의 이루어지지 않은 실정이다. 본 연구에서는 컨테이너선의 화물 중량 분포를 변화시켰을 때 피로 손상 기여도를 분석하고자 하였다. 일반적으로 설계 단계에서 적용하는 하중 조건뿐만 아니라 다양한 하중 조건을 생성하고 유체동역학 계산 으로 얻을 수 있는 선체 거더 하중 및 스펙트럴 피로 해석을 수행하여 얻은 피로 손상도를 확인하였다. 그 결과, 컨테이너선에서 화물 중 량 분포 변화는 선체 거더 하중을 변화시켰으며 선체 거더 응력에 영향을 주어 피로 손상의 변화를 야기시키는 것을 알 수 있었다.

In this study, using a 100mm gauge block in a contact-type three-dimensional measuring machine surface plate, an NPL-type angle measurement, and a steel ruler, the specimen was measured at 0°, 5°, 10°, 20°, 30°, and 40° along the X and Y axes. After setting the measurement conditions, the average value and standard deviation were confirmed by repeating measurements for each yield 10 times. After checking the statistical test value (P) through ANOVA, the correlation between the angle change and the error was checked.

This study investigated alterations in the health behaviors and eating habits due to the coronavirus disease 2019 (COVID- 19) pandemic. An online survey was administered to 270 university students from September 22, 2021 to October 26, 2021. While the frequency of eating at home had increased during the COVID-19 pandemic compared to before the pandemic, there was a decrease in the frequency of eating out, drinking, and eating vegetables. However, the frequency of eating delivery, takeout, and convenience foods and the utilization of online shopping and delivery apps had considerably increased. In addition, when selecting menus, considerations of health, hygiene, and convenience were more important during the COVID-19 pandemic than before the COVID-19 pandemic. Physical activity more than 3 days a week had decreased, whereas sedentary time showed a proportionate increase. The percentage of people who perceived their health status to be worsening was determined to have increased during the COVID-19 pandemic. To prepare for the era of infectious diseases, future research needs to identify health behaviors and dietary problems by administering surveys that include a large sample size and participants of various ages. Moreover, health promotion and nutrition management plans should be prepared accordingly.

Among migratory insect pests, Mythimna seperata and Cnaphalocrocis medinalis are invasive pests introduced into South Korea through westerlies from southern China. M. seperata and C. medinalis are insect pests that use rice as a host. They injure rice leaves and inhibit rice growth. To understand the distribution of M. seperata and C. medinalis, it is important to understand environmental factors such as temperature and humidity of their habitat. This study predicted current and future habitat suitability models for understanding the distribution of M. seperata and C. medinalis. Occurrence data, SSPs (Shared Socio-economic Pathways) scenario, and RCP (Representative Concentration Pathway) were applied to MaxEnt (Maximum Entropy), a machine learning model among SDM (Species Distribution Model). As a result, M. seperata and C. medinalis are aggregated on the west and south coasts where they have a host after migration from China. As a result of MaxEnt analysis, the contribution was high in the order of Land-cover data and DEM (Digital Elevation Model). In bioclimatic variables, BIO_4 (Temperature seasonality) was high in M. seperata and BIO_2 (Mean Diurnal Range) was found in C. medinalis. The habitat suitability model predicted that M. seperata and C. medinalis could inhabit most rice paddies.

글루탐산은 식물의 생장과 발달에 중요한 역할을 하는 필수 아미노산의 전구체이며, 저온 보호 물질로 이어지는 생합성 경로를 자극하여 저온 피해를 줄이는 생물자극제 중 하나이 다. 본 연구에서는 저온 스트레스 조건에서 글루탐산 엽면 처 리가 배추에 미치는 영향을 평가하였다. 글루탐산 2가지 엽면 시비 농도(0 및 10mg·L-1)와 3가지 주/야간 온도 수준(11/－1 °C extremely low, E; 16/4°C moderately low, M; 21/9°C optimal, O)을 결합하여 6개의 처리가 수행되었다. 글루탐산 의 엽면 처리는 정식 후 10일에 1회 살포하고, 글루탐산 처리 직후 온도 처리는 최대 4일 동안 실시하였다. 처리 4일 후, ABA, PA, DPA 및 ABA-GE 함량은 M 처리에서 Glu 0 처리 보다 Glu 10 처리에서 함량이 더 높았다. Glucose 함량은 E 및 Glu 10 처리에서 가장 높은 반면(52.1mg·100g-1 dry weight), fructose 함량은 O 및 Glu 0 처리에서 함량이 가장 높았다 (134.6mg·100g-1 dry weight). GLP, GBS, 4MGBS, GNBS 및 GNS 함량은 E 및 Glu 10 처리에서 모든 처리 중 가장 높았 다(0.72, 2.05, 1.67, 9.40 및 0.85μmol·g-1 dry weight). 처리 2일 후 E 및 Glu 10 처리의 PA와 DPA함량에서 급격한 변화 를 확인하였고, 몇몇 개별 glucosinolate 함량(GLP, GBS, 4MGBS, GNBS 및 GNS)은 저온과 글루탐산 처리에 따라 유 의적 차이를 확인할 수 있었다. 또한, fructose는 glucose 대신 fructan을 에너지원으로 사용하였기 때문에 처리 4일후 E와 M처리에서 O 처리에 비하여 유의적으로 낮은 함량을 보였다. 따라서, 저온과 글루탐산 엽면 처리에 따른 PA, DPA, glucose, fructose 및 개별 glucosinolate 물질들의 변이를 확 인하였지만, 저온과 글루탐산의 효과에 관한 명확한 상관관계를 평가할 수는 없었다. 배추과 작물은 호냉성 채소로서 저 온에 민감하게 반응하지 않고, 대부분 내한성을 가지고 있기 때문으로 판단된다.

The fish community in the Seomjin River-Seomjin River Estuary-Gwangyang Bay coast continuum was investigated three times from March 2019 to October 2019. The collected species at the eight sites during the survey period were 49 species belonging to 31 families, including two endangered species. According to Bray-Curtis similarities, observations were divided into four groups based on the fish community composition; two groups (group 1, 2) and two uncategorized groups (group 3, 4). ANOSIM based on spatial and temporal groupings indicated that the spatial differences in fish communities (R=0.398, P=0.001) were relatively more important than the temporal differences (analysis of similarities, R=0.273, P=0.002). In particular, there were significant differences between groups 1 and 2 (analysis of similarities, R=0.556, P=0.001), and similarity percentage analysis revealed that Argyrosomus argentatus (9.4%), Favonigobius gymnauchen (6.9%) and Konosirus punctatus (5.9%) contributed to these differences of fish assemblages for each group. The fish fauna distributed in the Seomjin River-Gwangyang Bay ecosystem were spatially divided and the number of species and number of individuals showed seasonal differences. This study could be a basis for understanding changes in the fish community and implementing conservation and management strategies on major species within a continuous environment of the river-estuary-ocean continuum.

본 논문은 원찰․원당의 시각에서 조선 시대 동학사 내 동학삼사(東鶴三 祠)의 불교사적 전개를 통해 이곳에 모셔져 있는 인물들을 위한 의례에 주목한 연구이다. 동학삼사에는 현재 단종을 비롯하여 단종의 거사를 돕 다 죽임을 당한 종친과 사육신 및 생육신, 관료 그리고 심지어 노비들도 제향되고 있다. 특히 계룡산 초혼각지(鷄龍山 招魂閣址)는 야은 길재가 동학사의 승려와 함께 단을 쌓고 고려의 국왕과 정몽주를 초혼하는 제사 를 지냈다는 점도 원찰 연구의 단초로 삼는다. 또 하나의 전각으로 숙모 전(肅慕殿)을 다룬다. 이곳은 계유정난을 계기로 등극한 세조가 단종을 폐위하면서 건립되게 된 조선의 역사적인 공간이다. 본 논문은 동학삼사의 공간을 단순히 유교의 사당이나 사우로 볼 수는 없다는 점에 집중하고 있다. 말하자면 숙모전을 포함한 동학삼사에 모셔 지고 제향되는 인물들의 면면들을 들여다보면, 이곳은 조선시대 유교 의 례와 불교적 죽음관 및 그 의식이 혼합되어 있는 양상을 보인다. 따라서 본 연구에서는 동학사 동학삼사의 공간/장소에서 특정 인물들을 제사해 온 역사를 일차적으로 분석한다. 이 과정에서 유교적․불교적 의례 혹은 이들 의례의 혼합양상이 번갈아가며 지속되는 양상을 포착할 수 있었다.

This study examines the effects of participation purpose, corporate readiness, and acceptance of changes that may occur in the course of expert guidance on the performance of smart factory. For this study, 129 questionnaires obtained from SMEs participating in the Smart Meister support project were used, and SPSS 18.0 and the AMOS 18.0 program were used for statistical processing for empirical analysis of the hypotheses test. It was found that the company's business participation motivation and readiness status had a significant effect on the acceptance and cooperation of changes that occurred during the consulting process. In addition, the acceptance and cooperation of changes within the company had a significant effect on the satisfaction with the Meister support project and the financial performance. Companies participating in the Meister support project need to clarify their motives for participating in the project and make stable corporate readiness in advance. In addition, based on the CEO’s support, it is necessary to have a motivational program and to build an organizational culture that can actively accept innovation.

In this study, the adsorption/desorption performance of toluene was evaluated using zeolite adsorbent to replace activated carbon with one-off and ignition characteristics. For the proper operation of the VOCs adsorption/desorption and condensate recovery steps, the operating range by various adsorption/desorption temperatures was selected. The adsorbent is a bead-type zeolite, which was put into an adsorption tower of 10 LPM scale. As a result, it was demonstrated that 0.079 mg/g was adsorbed at a low temperature (20°C) during adsorption. In the case of desorption, it was found that VOCs adsorbed on the adsorbent were completely recovered after the desorption operation at 220°C for about 160 minutes. However, in the heating rate step for desorption, it was not possible to maintain an appropriate heating rate by filling the tower with zeolite. This was complemented by applying a copper plate with high thermal conductivity, and it was shown that the time was shortened by about 10 minutes or more. When VOCs are emitted at high concentrations during the desorption process, they can be reused as energy resources through low-temperature maintenance, and a condensation method was attempted. The efficiency of condensing chiller (cooler) with temperature control and liquid nitrogen condensing was compared. It was found that the chiller condensing efficiency increased as the temperature decreased. In the case of liquid nitrogen condensation, the liquid nitrogen temperature was maintained at -196°C, showing a stable efficiency of 90%.

대기오염 등의 영향으로 실내 활동 시간이 증가하는 상황에서 뇌기능과 신체활동 측면에서 보다 건강한 실내 생활 을 위한 다양한 방안에 대한 고려가 절실한 실정이다. 본 연구는 실내 산소의 농도와 호흡의 방법에 따라 인지능력과 생체신호에 어떤 영향을 미치는지에 대해 연구하여 보다 건강한 실내 일상생활을 제안하고자 한다. 건강한 성인 20 명을 대상으로 공기 전달 시스템을 통해 공급된 공기를 산소마스크를 통해 흡입하도록 하였다. 호흡 방법과 산소 농도에 따른 변화를 확인하기 위해 모든 피험자는 3가지 호흡(비강, 구강, 및 고농도 산소공급과 함께 구강 호흡)을 인지부하자극(눈 감은 휴식기, 눈 뜬 휴식기, 1-back 및 2-back 작업기억 과제) 별로 각각 수행하였다. 자극에 대한 반응시간, 정확도 및 생체신호를 측정하여 호흡에 따른 인지부하별 변화를 분석하였다. 그 결과, 3가지 호흡에서 모 두 인지부하의 증가에 따라 심박동수는 유의하게 증가하면서 인지부하와 높은 상관성이 있는 생체신호임을 확인하 였다. 또한 구강호흡에서는 분당 호흡 횟수가 인지부하증가에 따라 유의하게 증가하는 변화가 나타났으며, 인지활동 시 구강호흡에서 부족한 산소공급을 보완하기 위한 생체신호의 변화를 확인하게 되었다. 반면 고농도 산소공급과 함께 수행한 구강호흡에서는 비강호흡과 같이 분당 호흡 횟수의 유의한 변화는 없는 것으로 나타났다. 이는 고농도 산소공급이 구강호흡과 같이 비효율적인 산소 흡입이나 산소 농도가 부족한 환경에서 이를 보완해 주는 역할을 할 가능성이 있음을 시사한다. 본 연구 결과를 기반으로 후속 연구에서는 자율신경계 변화까지 분석하여 인지 뿐만 아 니라 심리에 미치는 영향까지 종합적으로 규명하고자 한다.

In the historical city center where overall development has not been made, it is not difficult to observe the asp ect of the urban change process over time accumulated. Seochon(西村), which collectively refers to 13 legal dong s in the west of Gyeongbokgung Palace, is also considered a representative historical village with high value as a historical and cultural cityscape because of historical context remains throughout the lot. Therefore, research ex amining the process of changing parcels in this area is useful for a more three-dimensional understanding of the presence of several layers of time. In this study, relationship between the opening time of each road, the river co ver process, and the current building establishment process is examined using maps after the pre-modern period and modern era. In addition, to examine the specific change process of individual lots using the old land register, building management ledger and cadastral map.

The effect of change in exchange rates on an economy is very important, especially, to a small open economy like South Korea. I explore whether Free Trade Agreements (FTAs) have positive influences on exchange rate-pass through import price of import market for fishery products in South Korea. Competition among FTA partners is enhanced after FTAs are effective. I expect that the extent to which are exchange rate pass-through (hereafter, ERPT) into import price of fishery products (in terms of Korea currency) would be reduced since the import market for fishery products in South Korea is an oligopolistic market. Specifically, I　investigate two research questions with six South Korea’s FTA partners─Norway, Thailand, Peru, U.S., China and Vietnam. First, whether the extent to which are exchange rate pass-through into import price of fishery products from six FTA partners would decrase in the post-FTA era; seconds, the size of reduction has a negative relation with the size of their market share in the import market for fishery products in South Korea if it decreases. The empirical results indicate that the degree of ERPT into import price from other FTA partners than Norway has been reduced after FTA, statistically and significantly; however, I do not find the evidence that the size of reduction is related to their market share. The findings in this study imply that FTAs have negative effects on producers’ economic welfare in South Korea’s fishery industry by reducing the extent to which are exchange rate pass-through as well as reducing tariff barriers.

Purpose: This study aims to identify the differences in health behavior and depression before and during the COVID-19 pandemic for the aged in low-income homes in the community and to identify the factors that affect changes in depression. Methods: Participants were conveniently sampled 300 of 3,481 elderly people aged 65 or older registered as subjects of visiting health care services at a public health center in D-Gu, D City. The Linear Mixed Model was used to identify factors that affect the change in depression before and during the COVID-19 pandemic. Results: In the comparison between the pre-pandemic and the pandemic, there was an increase in the number of people experiencing falling, mild depression, and severe depression, Compared to the male elderly, the degree of experience of depression before and during the COVID-19 pandemic increased significantly in the aged women, as the age increased, the subjective health was poor, and when there was a falling experience. It was confirmed that the factor influencing the change in depression before and during the COVID-19 pandemic were age, subjective health, and falling experience. Conclusion: Considering the age, subjective health, and falling experience, which are the influencing factors of depression change, when visiting health care services are limited to the aged in the community during the COVID-19 pandemic, it is necessary to prioritize those with high age, poor subjective health, and those with falling experience.

본 연구는 무릎 MRI 검사 시 무릎의 위치가 보어 중심을 기준으로 거리가 멀어짐에 따라 무릎 연골 T2 값의 변화를 평가하고자 하였다. 이를 위해 무릎 질환이 없는 정상인 지원자 10명을 대상으로 하였고 보어 중심을 기준으로 무릎을 오른쪽으로 10 cm 그리고 20 cm 이동시키면서 영상을 획득하였다. 무릎 MRI 영상은 스핀에코기법을 활용하였고 무릎 연골의 T2 값을 계산하기 위해 TE 값은 13.8, 27.6, 41.4, 55.2, 그리고 69 ms로 적용하였다. 신호 측정은 무릎의 내, 외측 관절 융기가 가장 크게 나타난 영상의 대퇴 연골과 경골 연골에서 진행하였다. 연구의 결과, 재구성된 T2 값은 보어 중심에서 멀어질수록 감소하였다 (0 cm: 39.16 ms, 10 cm: 32.59 ms, 20 cm: 26 ms). 또한, 신호 값도 보어 중심에서 그 위치가 멀어질수록 감소하였다 (p<0.00). 특히, 보어 중심에서 20 cm까지 멀어짐에 따라 TE 69 ms의 영상에서 신호 값은 46.2%까지 감소하였다. 무릎 위치와 무릎 연골 T2 값의 상관관계분석 결과는 음의 상관관계 (r=-0.736)가 나타났다 (p<0.00). 결론적으로 MRI 검사에서 무릎 위치는 무릎 연골의 T2 값에 상당한 영향을 미치므로 T2 값의 정확도나 재현성 이 감소할 수 있다. 따라서 무릎 MRI 검사에서 무릎 연골의 정확한 T2 값을 획득하기 위해서는 최대한 보어 중심에서 검사가 이루어져야 한다.
