This study aims to review the use of graph databases in construction research. Based on the diagnosis of the current research status, a future research direction is proposed. The use of graph databases in construction research has been increasing because of the efficiency in expressing complex relations between entities in construction big data. However, no study has been conducted to review systematically the status quo of graph databases. This study analyzes 42 papers in total that deployed a graph model and graph database in construction research, both quantitatively and qualitatively. A keyword analysis, topic modeling, and qualitative content analysis were conducted. The review identified the research topics, types of data sources that compose a graph, and the graph database application methods and algorithms. Although the current research is still in a nascent stage, the graph database research has great potential to develop into an advanced stage, fused with artificial intelligence (AI) in the future, based on the active usage trends this study revealed.

Purpose - This study compares the management efficiency of retailers in China, Korea and other global countries. China's retail industry is experiencing a recession. In order to strengthen the competitiveness of retailers, it is necessary to manage the efficiency. Therefore, we analyzed the management efficiency of Chinese retailers as well as Korea and global retailers who are competing with Chinese retailers. Research design, data, and methodology - The DEA(Data Envelopment Analysis) carried out for evaluating the relative efficiency of multiple DMUs (decision making units) with homogeneity. Data were collected from the American Retail Trade Association (2017). In those distributors' data, 5 of China and 5 of Korea and 10 of other global countries' analyzed. CCR and BCC analysis were performed to determine the cause of the inefficiency of DMUs by measuring the technical efficiency, pure technology efficiency and scale efficiency. Result - Among the 20 retail distributors, Costco, Kroger (Global), Eland World, BGF(Korea) are operating efficiently. Chinese retailers are operating inefficiently. Retailers' CRS status means the growth rate of input is equal to the growth rate of output. In the case of DRS status, the ratio of output to input variable is much smaller. In order to improve inefficiency, reducing input variables can be a solution. For the firms in IRS status, the rate of increase in output is relative greater than the input. That means efficiency is good condition. The analysis result shows that most retailers are showing DRS status especially Chinese retailers. Scale efficiency is a major cause of inefficiency rather than pure technology efficiency. It is recommended for ineffective retailers to reduce inputs to become efficient retailers. Otherwise, retrain existing employees or introducing advanced technologies to increase the output. Conclusions - Most of Chinese retailers are operating inefficiently which caused by the excessive investment in the inputs. On the other hand, Other global retailers are analyzed to be efficient by DEA. In this study, benchmarking targets of some retailers' suggested to improve the management efficiency especially in inputs.

We investigated the effect of paternal folate status on folate content and expression of the folate transporter folate receptor ${\alpha}$ ($FR{\alpha}$) in rat placental tissues. Rats were mated after males were fed a diet containing 0 mg of folic acid/kg of diet (paternal folate-deficient, PD) or 8 mg folic acid/kg of diet (paternal folate-supplemented, PS) for 4 weeks. At 20 days of gestation, the litter size, placental weight, and fetal weight were measured, and placental folate content (n=8/group) and expression of $FR{\alpha}$ (n=10/group) were analyzed by microbiological assay and Western blot analysis, respectively. Although there was no difference observed in litter size or fetal weight, but significant reduction (10%) in the weight of the placenta was observed in the PD group compared to that in the PS group. In the PD group, placental folate content was significantly lower (by 35%), whereas $FR{\alpha}$ expression was higher (by 130%) compared to the PS group. Our results suggest that paternal folate status plays a critical role in regulating placental folate metabolism and transport.

'ISO 37001 - Anti-bribery Management Systems, one of the Business Ethics of Global Standards, is a new standard to help organizations fight bribery and promote an ethical business culture which was developed in 2016. ISO 37001 can provide the tools and systems to greatly reduce the risk and help organizations deal with it effectively if it does arise. After enforcing the Improper Solicitation and Graft Act, Korean government standardized ISO 37001 harmonizing International Standards into Korean Industrial Standards (KS) in 2017. It is meaningful in that Korean companies have localized regulation which applies to global standard anti-bribery management systems. About 100 organizations have adopted ISO 37001 as in the first half of 2019. So far many side effects of other ISO certifications have been recognized. Therefore, it is necessary to investigate the current status of ISO 37001 in Korea for effective operation and management. The primary purpose of this paper is to investigate the current status and problems of ISO 37001 in Korea. It can provide useful guidelines for improving ISO 37001 to manage bribe and corruption effectively.

This study was conducted to examine the relationship between socio-familial characteristics and health status in early stage of elderly life. In this study, a total of 252 Korean males and females aged 55 to 74 were interviewed to obtain information on various socio-familial characteristics such as age, gender, residence, marital status, education, religion, distance with children, household size, and living arrangements. They were also examined for self-perceived depression and diagnosed health problems. The analysis of the results show that marital status, gender, and living arrangement were major characteristics differentiating health status; widowed women living apart from their children are at lower level for most items of hea1th status such as emotional, circulatory, respiratory, digestive, and muscle and skeletal function. Based on this analysis, suggestions are made for efficient health management. First, widowed females living without children are encouraged to participate in regular health promotion programs in self-organized groups. Second, usual welfare service programs need to be segregated for each age group, so that relatively young elderly are not frustrated from being treated together with extremely frail older elderly. Third, low education group living in rural area are offered preventive medical services for muscular and skeletal related health problems.
