AAALAC International is a private, nonprofit organization that promotes humane treatment of animals in science through a voluntary international accreditation program. AAALAC International accreditation is recognized around the world as a symbol of high quality animal care and use for research, teaching and testing, as well as promoting animal welfare. Animals owned by the institution that are used for research, teaching and testing are included as part of an accredited program. More than 990 animal care and use institutions in 42 countries around the world (more than 170 programs in 13 countries in the Pacific Rim region) have earned AAALAC International accreditation. The AAALAC International Council on Accreditation evaluates overall performance and all aspects of an animal care and use program, involving an in-depth, multilayered, confidential peer-review process. The evaluators (site visitors) consider compliance with applicable local animal legislation of the host country, institutional policies, and employ a customized approach for evaluating overall program performance using a series of primary standards that include the Guide for the Care and Use of Laboratory Animals, the Guide for the Care and Use of Agricultural Animals in Research and Teaching, or the European Convention for the Protection of Vertebrate Animals Used for Experimental and Other Purposes, Council of Europe (ETS 123), and supplemental Reference Resources, as applicable.

This study compared the disasters in construction field under construction amount of 300,000,000 won and the whole construction fields in order to improve the efficacy of various industrial safety and health policies and services and examined the characteristics of disasters in construction field under 300,000,000 won. It also examined, compared and analyzed the characteristics of disaster in construction field under construction amount of 300,000,000 won that disaster prevention technical experts saw. The subjects of comparison were selected with statistical data of disaster for 2011 and those of disaster in construction field under construction amount of 300,000,000 won from January to August of 2012. And questionnaire was conducted with technical instruction experts of small-sized construction field and priority was drawn, compared and analyzed with AHP. Consequently, the results of different views between actual disaster data and experts' views were obtained. Therefore, this study suggested the characteristics of disaster in construction field under construction amount of 300,000,000 won and presented the methods for improving disaster prevention technical experts.

The purposes of this study were to promote the consumer's recognition on the internet purchase of fashion products and to provide useful information which would help web-site plan design, product composition, and service of internet shopping mall. The subjects were consisted of 693 students who had experiences of the accesses to internet fashion shopping mills or experiences of purchasing through internet in Cheongju and Daejeon region. Data were analyzed by factor analysis, frequency, percentage, mean, standard deviation, t-test, ANOVA, and LSD. The Results were as follows: 1. Merit factors of the internet shopping were found to be shopping convenience and pursuit of product information. Whereas, demerit factors of the internet shopping to be complexity of order, delivery, functional and economic riskiness, and services. 2. Gender was the only factor differentiating the level of recognition toward the internet fashion shopping mall. And the level of recognition also showed significant differences according to period, time, purpose of access, type of shopping mall, purchase experience, and average purchase price.

Sensors collect information for Internet of Things (IoT)-based services. However, indoor construction sites have a poor communication environment and many interfering elements that make it difficult to collect sensor information. In this study, a network was constructed between a Bluetooth Low Energy (BLE)-based IoT device based on a serverless IoT framework and a router. This experimental environment was applied to large- and small-scale indoor construction sites. Experiments were performed to test the communication performance of BLE-based IoT devices and routers at indoor construction sites. An analysis of the received signal strength indication (RSSI) graph patterns collected from the communication between the BLE-based IoT devices and routers for different testbed site situation revealed areas with good communication performance and poor communication performance due to interfering factors. The results confirmed that structural components of the building as well as the materials, equipment, and temporary facilities used in indoor construction interfere with the communication performance. Construction project managers will require improved technical knowledge of IoT, such as optimizing the router placement and matching communication between the router and workers, to improve the communication performance for large-scale indoor construction.

The study presents work information classification system of apartment house which can organize all construction management services throughout the planning and management of a construction such as the decomposition of the design process, the assembly of construction process and cost estimating, etc. In addition, the study suggested a way to connect work information classification system based on a relational database in working order and built a conceptual model for automated cost estimating by utilizing established data base. A conceptual model for automated cost estimating will resolve the fundamental problems of the existing cost estimating system and will be able to take advantage of scientific cost estimating system at the construction site of apartment house.

Objective: Suicide has recently become an important social problem. Thus, we analyzed prescription drugs that cause suicidal ideation. Methods: Of 156 drugs on the the Minister of Food and Drug Safty (MFDS) EZ-Drug site that had "suicide" listed as a side effect, 78 had "suicide" listed as a warning or contraindication; those 78 drugs were analyzed using data from the 2016 Health Insurance and Review and Assessment Services National Patient Sample (HIRA-NPS). Results: 51 "suicide risk" drugs was identified. Of all patients, 5.2% had received such drugs. The prescription rate was 0.8% of all prescriptions, accounting for 1.6% of all prescription days. From logistic regression analysis, the prescription rate for the drugs was approximately 1.1 times higher for women than for men. With regard to age, the prescription rate for patients 66 years and older was 15.5 times higher than those for patients 25-years and lower. With regard to medical departments, the prescription rates in psychiatry and dermatology departments were 8.1 times higher and 0.6 times lower than those in internal medicine departments, respectively. With regard to region, the prescription rates in Daegu and Jeju were 1.3 times higher and 0.79 times lower than those in Seoul, respectively. Conclusion: Drug-induced suicidal behavior is possible, and therefore efforts are needed to prevent it.

While medical services are recognized to be crucial in a process of disease treatment, the research has been done with the service space and waiting time in a medical institution. This paper's objective is to evaluate the waiting areas of lobby, outpatient clinic, operating room in a general hospital and to draw factors of architecture design for further improvement, identifying strengths and weaknesses to be analyzed in terms of medical service. Research method is to define concepts of waiting time through literature review and advanced researches, analyze characteristics of architectural plan through drawing analysis and site survey. This research will contribute to the improvements of the planning methods which will reduce the waiting time and increase the quality of medical service.

In a manufacturing fields, an abnormality or breakdown of equipment is a factor that causes product defects. Recently, with the spread of smart factory services, a lot of research to predict and prevent machine's failures is actively ongoing. However, there is a big difficulty in developing a classification model because the number of abnormal or failure data of the machine is severely smaller than normal data. In this paper, we present an algorithm for detecting abnormalities in an MCT at manufacturing work site depending on the differences between inputs and outputs of Autoencoder model and analyze its performance. The algorithm detects abnormalities using only features of normal data from manufacturing data of the MCT in which abnormal data does not exist.
