Objectives: The purpose of this study is to analyze the effectiveness of Guibi-tang that are used for postpartum depression. Methods: We searched on five databases [Korean studies Information Service (KISS), Oriental medicine advanced searching integrated system (OASIS), The Cochrane Library, PubMed, and China national knowledge infrastructure (CNKI)] with keywords for Postpartum depression (English, Korean, and Chinese) and evaluated the risk of bias. Meta-analysis was performed on the selected studies. Results: 8 potentially relevant articles were retrieved for further evaluation. There was evidence that Guibi-tang compared with Western medicine was significantly higher rate in total effect rate (RR 1.20, 95% CI 1.04, 1.39, p=0.01). Also, the combined therapeutic effects of Guibi-tang and Psychological intervention compared with Psychological intervention were statistically significant in total effect rate (RR 1.14, 95% CI 1.05, 1.24, p=0.002). And they showed improvement on scores of HAMD (Hamilton depression scale, HAMD) and SF-36 (36-Item short form health survey, SF-36). Conclusion: Guibi-tang appears to be more effective compared to Western medicine in the treatment of postpartum depression. The combination Guibi-tang and Psychological intervention was more effective than psychological intervention alone treated for postpartum depression. However, since unclear risk of bias, the result of this study should be considered carefully. Further clinical trials should be carried out in order to academical clinical progress regarding treatment of Postpartum Depression.

Background: Occipital neuralgia (ON) is an established risk factor for headaches in the posterior cervical region. Several conservative treatments by nerve decompression and pain relief are available for ON, but these treatments have limitations. Acupuncture treatment, which is known to demonstrate analgesic effects, involves various stimulation methods, and several studies have reported their clinical benefit. No recent systematic review (SR) has compared each acupuncture type for ON treatment. Thus, this SR aims to investigate the clinical effectiveness of each acupuncture type for treating ON. Methods: We will identify relevant studies using electronic databases, including EMBASE, MEDLINE, Cochrane Library, China National Knowledge Infrastructure (CNKI), Korean Studies Information Service System (KISS), Korean Medical Database, KoreaMed, and National Digital Science Library (NDSL) from the inception until August 2023. The primary outcome will include the numerical change of pain symptoms (visual analog scale and numerical rating scale) and effective rate. Safety and secondary outcomes will include adverse events and quality of life. We will compare the conservative treatment with the acupuncture treatment using network meta-analysis. The Cochrane Collaboration "risk of bias" tools will be used to assess the quality of included trials. The Grades of Recommendation, Assessment, Development, and Evaluation will be used to examine the evidence level. Conclusion: This study will provide clinical evidence of several acupuncture types for ON and help clinicians decide on the best.

Objectives: The purpose of this study is to review the research trends of infertile women with uterine myoma in Korean medicine and to recognize the efficacy of Korean medicine intervention. Methods: A search was conducted on November 18, 2022, using six databases, including Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Cochrane Library Central, Pubmed, China National Knowledge Infrastructure (CNKI) and WangFang Med Online. We analyzed the studies using Korean medicine on women with uterine myoma preparing for pregnancy or complaining infertility. Results: Total 4 studies were selected and all of which were case reports. Among 6 cases, Korean medicine treatment including herbal medicine, acupuncture, electroacupuncture, moxibustion was used alone. Ikgibohyeol-tang-gami-bang, Gyejibokryeong-hwan, Saenghwa-tang-gami-bang were prescribed in 2 cases each. Angelicae Gigantis Radix and CV4 were most frequently used herb and acupoint. All subjects were successful in becoming pregnant. Conclusion: This review shows that Korean medicine treatment can be effective in infertile women with uterine myoma. However, the number of included studies is small, so the level of evidence needs to be raised through more clinical studies in the future.

This study raises the need to establish a 'Presidential Digital Archive Platform' that actively shares and opens related information and data by linking and integrating the presidential knowledge infrastructure. The Presidential Digital Archive Platform can promote the quality and value of presidential records as a "Governance Platform" where "Presidential Archives", "Presidential Archives-related Institutions" and "users" can interact through presidential records. And it will provide an opportunity to create a new paradigm. For this purpose, 'Presidential archives portal analysis' and 'Presidential Archives-related Institutions analysis' will be conducted to identify improvements and requirements when establishing the Presidential Digital Archive Platform. In addition to deriving implications through 'Digital Archive Platform case analysis' at home and abroad, measures to strengthen presidential archival reference services were discussed. Finally, based on the results, a step-by-step implementation strategy for platform construction was presented.

The purpose of this study is to empirically analyze the rational decision-making process and perception differences of housing transactions in the market environment. It was designed through an analysis of the factors influencing housing sales based on the rational behavior theory model. Objective evidence was provided for the impact factors affecting the attitude towards housing sales, with the spouse and children being identified as significant influencers. Additionally, children and friends were found to have an impact on subjective norms related to housing sales, especially for unmarried individuals under 40 years of age and those with low income, who were found to be more influenced by their parents. It was also discovered that the influence of these factors varied based on age and income levels. Younger individuals tended to rely more on their parents or friends, while those with high incomes showed stronger willingness to purchase homes. The presence of beneficial infrastructure for children was found to directly influence the decision to purchase a home. The study also provided objective evidence that the decision to purchase a home is influenced not only by economic factors but also by continuous encouragement and information from those around the buyer. These findings demonstrate the importance of the influence of close acquaintances in the rational decision-making process of home buyers. However, this study only investigated a limited portion of the factors influencing housing sales, as the market is affected by a variety of financial and governmental policies. Therefore, future research should consider various complex factors simultaneously when analyzing the influence of housing sales.

The number of old buildings in Korea is increasing. According to a report from the Ministry of Land, Infrastructure and Transport, the proportion of old buildings increased from 29.0% in 2005 to 37.8% in 2009. However, the ratio of repairs to improve usability and improve the environment through problem improvement The proportion of old buildings was 72% in 2010, but decreased to 38% in 2020 and does not exceed 40%. The reason is that the difficulty of remodeling old buildings is more difficult than repairing new ones, and business estimates are difficult to predict. Accurately reflecting the current condition of a building in a repair project has a huge impact on time and budget. Accurate and detailed measurements are essential. Current repair methodologies require a lot of manpower, time and money to remodel an old building. Therefore, it is necessary to improve the remodeling methodology applied in the field. In this study proposed a Digital-Twin-based remodeling process that introduced various digital technologies such as 3D Scanning, BIM, Reverse Engineering, and Digital Fabrictation in consideration of the latest technologies used in recent construction projects. In addition, the process proposed in this study was applied to an actual small-scale building remodeling project and the results were analyzed. In addition, useful basic data were provided for the establishment of plans related to the repair process of buildings in the future.

Korea is facing a number difficulties arising from rising housing prices. As 'housing' takes the lion's share in personal assets, many difficulties are expected to arise from fluctuating housing prices. The purpose of this study is creating housing price prediction model to prevent such risks and induce reasonable real estate purchases. This study made many attempts for understanding real estate instability and creating appropriate housing price prediction model. This study predicted and validated housing prices by using the LSTM technique - a type of Artificial Intelligence deep learning technology. LSTM is a network in which cell state and hidden state are recursively calculated in a structure which added cell state, which is conveyor belt role, to the existing RNN's hidden state. The real sale prices of apartments in autonomous districts ranging from January 2006 to December 2019 were collected through the Ministry of Land, Infrastructure, and Transport's real sale price open system and basic apartment and commercial district information were collected through the Public Data Portal and the Seoul Metropolitan City Data. The collected real sale price data were scaled based on monthly average sale price and a total of 168 data were organized by preprocessing respective data based on address. In order to predict prices, the LSTM implementation process was conducted by setting training period as 29 months (April 2015 to August 2017), validation period as 13 months (September 2017 to September 2018), and test period as 13 months (December 2018 to December 2019) according to time series data set. As a result of this study for predicting 'prices', there have been the following results. Firstly, this study obtained 76 percent of prediction similarity. We tried to design a prediction model of real estate transaction price with the LSTM Model based on AI and Bigdata. The final prediction model was created by collecting time series data, which identified the fact that 76 percent model can be made. This validated that predicting rate of return through the LSTM method can gain reliability.
