Klaus Schwab's discussion on the Fourth Industrial Revolution provides a framework for predicting the direction of legal technology development. Technological convergence, which has emerged as the core concept of the Fourth Industrial Revolution has a significant effect on legal technology. In particular, various new technologies, such as legal chatbots and platforms, are being introduced to enhance efficiency and accessibility in the legal field. However, legal technology is still in its early stage, with institutional improvement needed to vitalize the industry. In this paper, we first specify the concept and classification of legal technology in Chapter 2, followed by trends and limitations in Chapter 3 and ways of vitalizing legal technology in the future in Chapter 4. To invigorate legal technology development, it is necessary to put in place legal regulatory measures that stipulate the active disclosure of legal data, such as precedents, and make free use of such measures. In the law, many issues, such as the safety of artificial intelligence, personal information protection, and ethical standards, will be discussed in the future. Therefore, via this paper, we hope to promote the formation of social consensus and prepare countermeasures, such as legislative measures.

We analyzed both current local policies and in-depth survey data to find out a way to provide job opportunity and income source to local young people in so-called job guarantee system. The young generation in current Korean society has been experiencing both growth without employment and severe economic inequality at the same time, though they should have taken part actively in social development. Their rights for work and survival have also been threatened and losing hope for the future is an widespread symptom in this generation. Kwangju metropolitan city(KMC) has been supporting certain amount of case income and job experience to young people in Kwangju through a local government policy called Kwangju Young Generation Job Experience Dream Service. In spite of high level of satisfaction from the participants, limitations such as below average job performance level of participants and a barrier in the transition to regular position still remain. This study hopes that a case of Kwangju gives pragmatic insights for a realizable path to expanding universal welfare through assuring job opportunity to the young generation in local area.

The purpose of this study was to develop and validate the Psychological Difficulties Scale of Working Moms(PDSWM). In the first study, 69items and 17 factors of the inventory were obtained based on interview, open-ended questionnaires. In the second study, the on-line surveys from 306 working mom was carried to analyze factor structure of the PDSWM. The final result showed that the 12 factor model with 64 items was appropriate. The third study was collected from 638 working mom and in order to make certain the cross-validity of the inventory, the group was divided into two groups (each group with 319 employees). The results of exploratory factor analyses using data of group 1 showed that the 8 factor structure with 48 items was appropriate. Also the results of confirmatory factor analysis using data of group 2 showed that the 8 factor structure indicated a satisfactory fit. Final 8 factors were as follows: 1) Feeling Apologetic to family members 2) Discrimination at workplace 3) burnt-out: both body and mind 4) Unequal distribution of child-rearing and house chore labor 5) Conflict with the babysitter/grandparents 6) Limit in further strengthening work competency 7) Social prejudice 8) Difficulty being on time for work. The PDSWM was significantly correlated with various criteria such as organizational commitment, life satisfaction, and work engagement. Based on such findings, implications, limitations, and the suggestions for future study were discussed.

The purpose of this study is to forecast future changes in the construction market following the reorganization of the construction production system by analyzing the possible market size in which general contractors and specialty contractors may participate in each other, and by carrying out a survey. The ratio of correlation between general construction and specialty construction industries was derived by analyzing the relevance of work area of general contractors and specialty contractors, the similarity of registration standards, and the market in which general contractors and specialty contractors may be able to mutually participate. In order to overcome the limitation of previous studies which analyze the changes in construction market based on the statistical data, and to analyze in more detail the impact of reorganization of construction production system from market participants' view, a survey targeting general contractors and specialty contractors for their willingness and method of participating in the mutual market was conducted. As a result of the survey, it was found that 52% of general contractors were willing to participate in the specialized construction market and 55.1% of specialty contractors were willing to participate in the general construction market. It was found that there was a high willingness to participate in the earthworks, reinforced concrete works, facility maintenance and management, water and sewage facility works, and interior works, and high competition is expected for projects with a scale of 500 million to less than 3 billion won. Through this study, it will be possible for general and specialty contractors to understand the changes in the construction market due to the reorganization of the construction industry production system, and to respond effectively to these changes.

In order to understand a record, not only the contents of the record but also the production background and work context of the record must be grasped. It also requires a function that makes it easy to find related records scattered across various departments and agencies. Accordingly, the 'linkage' of information in archival information services is becoming more important. NAK also emphasizes 'linkage' as a search service function of the archives management system, but some problems were identified at the National Archives Portal Service (NAPS) such as a lack of linkage with authority data, disruption of internal service, and absence of linkage with other related organizations. To solve the limitations of the NAPS, we selected and analyzed advanced record management institutions that have built an ideal linkage service; checked the overall linkage structure of these institutions; and identified characteristics that could not be seen by other institutions. Also, elements that can be adopted from the NAPS were derived. Next, the current status of the NAPS linkage structure was analyzed to identify the parts that were not linked and the items that need to be improved in the linkage method, and specific advancement plans were suggested to solve these problems. The purpose of this study is to increase users' satisfaction with search and to advance the accessibility and utilization of records and internal services through improved linkage services of NAPS.

홍수는 단기간의 사상이다. 평상시 유량은 일단위로 연속유량이라 한다. 홍수해석은 사상 모형을 이용하고, 물 이용의 용수계획에서는 연속 모형에 의한다. 평상시 유량을 홍수처럼 10분, 30분, 60분 단위로 해석할 수 있으면 여러 가지로 편리하다. 홍수기에는 홍수와 이수를 동시에 분석할 수 있는 이점이 있다. 평상시에는 수문자료가 생성되는 기본단위가 10분, 60분이기 때문에 이와 일치하여 유량을 해석할 수 있는 이점이 있다. 특히 저수지에서는 운영자료가 저수율 자료만 관리되고 있는 현실을 감안하면, 연속 홍수모의의 필요성은 매우 높다. 다목적댐도 그 편의성은 말로 형용할 수 없는 수준이다. 홍수모의는 첨두유량도 중요하고, 전체 누적유량도 중요하다. 여기서는 당초 일 단위로 개발된 ONE 모형으로 연속 홍수모의의 가능성을 타진했다. 모형의 검증은 홍수사상 마다 훨씬 긴 장기간의 댐의 유입량, 저수량 오차로 실시했다. 유입량이 누적되면 저수량이 되기 때문에 저수량을 비교하면 확실한 검증 방법이 된다. 유역면적 930.0km², 총저수량 8억1,500만m³인 용담댐과 유역면적 218.80km², 유효저수량 3,498만m³인 탑정지를 대상으로 60단위의 장기간 연속 홍수모의 결과를 제시한다. 첫째, 용담댐에 대해 2020년 3월1일부터 6월30일까지 연속유입량을 모의한 결과(ONE모형 매개변수 α=3.18), 면적우량은 최대 12.5mm, 총 371.2mm(3억4,522만m³)였고, 유입량은 최대 1,363.0m³/s, 총 1억8,326만m³로 유출률 53.1%였다, 관측 유입량은 최대 766.1m³/s, 총 2억9,152만m³로 유출률 84.4%로 나타났다. 관측 유입량이 높은 것으로 평가했는데 그 이유는 산정된 유입량이 넓은 수면적에서 오는 음유입량이 발생하는데 이를 0으로 처리하고, 음의 누적 값이 전체유량에 더해지는 계산의 한계에서 비롯한다. 이는 현실적 제한이며, 개선이 필요하다. 댐 수위로 검증한 결과는 관측수위는 EL.257.97~262.92m, 평균 EL.260.40m, 모의수위는 EL.257.22~262.88m, 평균 EL.260.02m로 나타났고, RMSE는 0.174, NSE는 0.959, R²는 0.968로 만족한 결과를 얻었다. 둘째, 탑정지에 대해 2020년 3월1일부터 6월30일까지 연속유입량을 모의한 결과(ONE모형 매개변수 α=3.18), 면적우량은 최대 18.5mm, 총 311.4mm(6,813만m³)였고, 유입량은 최대 187.8m³/s, 총 3,691만m³로 유출률 54.2%였다. 저수지 수위로 검증한 결과 관측수위는 EL.26.55~29.79m, 평균 EL.29.01m, 모의수위는 EL.26.16~29.92m, 평균 EL.29.07m로 나타났고, RMSE는 0.563, NSE는 0.877, R²는 0.943로 만족한 결과를 얻었다. 정리하면 2020년 4개월의 장기간 용담댐과 탑정지에 대한 1시간 간격의 연속 홍수모의의 결과는 그 활용 가능성이 충분하다고 말하고 있다. 이 결과로부터 평상시 댐과 저수지의 실시간 운영자료 검증 및 생산체제의 수문관측업무에 활용 가능한 것으로 평가했다.

Using the dynamic panel model, this study investigates rent determinants for small and medium-sized office buildings in Korea's CBD and Gangnam areas, key business districts. The results reveal that rents for small and medium-sized office buildings in CBD and Gangnam areas are influenced by macroeconomic fluctuations and characteristics of buildings and locations, suggesting a market with both spatial consumer and investment goods attributes. There are several investment implications as follows. First, even if the location in the CBD area is advantageous, the practical limitations in renovating aging small and medium-sized office buildings must be taken into account when investing. Second, parking conditions are a key factor influencing rent prices in CBD areas, so evaluating the parking facilities and improvement potential of small and medium-sized office buildings is essential for investors. Finally, due to the high sensitivity of Gangnam's small and medium-sized office market to macroeconomic trends, it's vital to prioritize monetary policy shifts as a key factor in investment decisions.

The study aims to synthesize the discussion of the innovation district and suggest an alternative to the governance system of the innovation district. Cluster policies that focus on industrial specialization, networking, value chains, and industrial ecosystems have shown some problems and limits in advanced industrial economies. The innovation district, suitable for the era of urban innovation, convergence of industry, housing, leisure, and related variety, emphasizes cooperation through the convergence of various innovations, workshops and industries, and communities. It is important to build a quintuple helix based on cooperative governance through public-private partnerships, integrate the physical and cultural atmosphere, and service industries that strengthen the place prestige. Beyond the industrial aspect, innovation districts can facilitate changes in urban amenities and lifestyles and creative atmosphere, such as diversity, lifestyle, charms, and openness, and promote social vitality and economic interactions. The governance of innovative districts can promote inter-organizational exchanges, and combinations. When knowledge is created through exchanges between companies, it also affects changes in the governance system, evolving from a rigid and centralized system to an open, dynamic, and organic system. Through the innovation policy, the existing Central Business Districts (CBD) can be able to be transformed into a Central Lifestyle Districts (CLD).

Understanding accurate traffic performance is crucial for ensuring efficient highway operation and providing a sustainable mobility environment. On the other hand, an immediate and precise estimation of highway traffic performance faces challenges because of infrastructure and technological constraints, data processing complexities, and limitations in using integrated big data. This paper introduces a framework for estimating traffic performance by analyzing real-time data sourced from toll collection systems and dedicated short-range communications used on highways. In particular, this study addresses the data errors arising from segmented information in data, influencing the individual travel trajectories of vehicles and establishing a more reliable Origin-Destination (OD) framework. The study revealed the necessity of trip linkage for accurate estimations when consecutive segments of individual vehicle travel within the OD occur within a 20-minute window. By linking these trip ODs, the daily average highway traffic performance for South Korea was estimated to be248,624 thousand vehicle kilometers per day. This value shows an increase of approximately 458 thousand vehicle kilometers per day compared to the 248,166 thousand vehicle kilometers per day reported in the highway operations manual. This outcome highlights the potential for supplementing previously omitted traffic performance data through the methodology proposed in this study.

The timeliness and accuracy of test results are crucial factors for clinicians to decide and promptly administer effective and targeted antimicrobial therapy, especially in life-threatening infections or when vital organs and functions, such as sight, are at risk. Further research is needed to refine and optimize matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS)-based assays to obtain accurate and reliable results in the shortest time possible. MALDI-TOF MS-based bacterial identification focuses primarily on techniques for isolating and purifying pathogens from clinical samples, the expansion of spectral libraries, and the upgrading of software. As technology advances, many MALDI-based microbial identification databases and systems have been licensed and put into clinical use. Nevertheless, it is still necessary to develop MALDI-TOF MS-based antimicrobial-resistance analysis for comprehensive clinical microbiology characterization. The important applications of MALDI-TOF MS in clinical research include specific application categories, common analytes, main methods, limitations, and solutions. In order to utilize clinical microbiology laboratories, it is essential to secure expertise through education and training of clinical laboratory scientists, and database construction and experience must be maximized. In the future, MALDI-TOF mass spectrometry is expected to be applied in various fields through the use of more powerful databases.
