In this Paper, there have been brief review about the important consideration in laboratory planning and designing the dielectric testing facilities for heavy electric apparatus up to 800kV-class in the high voltage testing fields. To improve and reinforce the existing dielectric test facilities in the way of econo-mical and optimal condition, wide investigation and an analysis for a solution, especially overshoot compensation method. have been suggested. With the brief description about those matters in constructing and improving the test facilities, the specification of each facility has been shown in the paper.

To verify the performance of roadside safety facilities, strength and occupant protection test are performed by evaluation criteria. Strength test use a truck and occupant protection test use a sedan. Strength perfomance is analyzed pass rate by post lateral resistance of the safety barrier. Occupant protection performance is analyzed from THIV(Theoretical Head Impact Velocity) and PHD(Post-impact Head Deceleration) by crash cushion test.

This study evaluated the effectiveness of a visiting inspection and knowledge-based food safety education program for cooks in child care facilities provided by the Center for Children's Foodservice Management (CCFSM). The research was conducted among cooks at 91 child care facilities; 56 existing facilities had been enrolled since 2011 and provided with the inspection and education program for 2 years and 35 new facilities were enrolled in 2012 and provided with the program for 1 year. The food safety knowledge of the cooks of the two groups were compared by the presence and duration of inspection and education programs provided by the CCFSM. The total mean score for food safety knowledge was $18.48{\pm}3.09$, with a group score of $19.34{\pm}2.68$ for the existing facilities and $17.11{\pm}3.25$ for the new facilities (P<0.001). There was no significant difference between groups in the knowledge of the personal sanitation. According to a post-test for food safety knowledge in the two groups after the completion of a one-year program on food safety by CCFSM, the mean score of food safety knowledge increased by 2.92 to 20.03 for cooks of the new facilities and both groups had significantly higher mean scores than pre-test (P<0.001). There was no significant difference in the mean score of each group by post-test. Thus, the one-year continuous program by CCFSM was effective in improving food safety knowledge of the cooks of the child care facilities.

As increasing underground facilities, more effective management is needed nowadays. It is important to get an accurate information of underground facilities to manage that, so some methods of detecting location - electromagnetic induction method, ground penetration radar method, sonic method - are used to obtain the information of underground facilities. In this study, a magnetic method to detect underground facilities was developed. In the magnetic method, underground facilities are detected by a detector and the magnetic marker which is a permanent magnet and used to marking the location by attaching underground facilities. A proper characteristic of the magnetic marker was optimized by maxwell 20 magnetic field analysis tool, a test field was constructed with the magnetic marker, PVC pipe, and steel pipe under ground 1.5m, and the detector was made by modifying a common ferromagnetic detector. Magnetic strengths of the magnetic marker were measured by the detector at each location in the test field, and analyzed by magnetic field analysis tool in the same condition. In the result, the underground pipes were detectable within the deviation ${\pm}20cm$ at PVC pipe and ${\pm}10cm$ at steel pipe respectively. The steel pipe was more detectable by ferromagnetism. The developed magnetic method can be applied to maintain and manage underground facilities.

Cervical cancer, the second most common malignancy all over the world, is associated with HPV infection. In a developing country like India, lack of early detection and treatment facilities is the main cause for its high burden. Therefore, through our study we e tried to present the current scenario of existing facilities for the detection and treatment of cervical cancer in hospitals and primary health centers (PHCs) of Delhi-NCR region. Data were collected from 312 healthcare facilities including public and private hospitals and PHCs of all nine districts from Delhi-NCR region. Healthcare providers including gynecologists, medical officers, women health care providers and paramedical staff were interviewed, using a questionnaire; the facilities for screening, diagnosing, and treating cervical cancer in each institution were recorded, using a previously designed checklist. Our study has shown that the basic facilities for the detection and treatment of cervical cancer are abhorrently lacking in Public hospitals and PHCs as compared to the Private hospitals in Delhi-NCR region. This study demonstrates that there is an urgent need for more investment in the diagnosis and treatment of cervical cancer facilities in public and rural healthcare facilities of Delhi-NCR region.

The Propulsion Test Facilities for the development of Korea Space Launch Vehicle-II are being built, some test facilities are completed and various combustion tests are running. The Propulsion Test Facilities consists test-stand, which carries out tests for engine development model, and various sub-systems and vessels containing LOX and Jet A-1 as propellant. There are always risks of fire and explosion at the test-stand since engine development model is conducted at test-stand with real combustion test with very high pressure, mixed propellant and high energy. In this paper, in order to establish the consequence analysis and risk reduction measures in the Propulsion Test Facilities, followings are considered. 1) a propellant leak accident scenario is assumed in test-stand. 2) TNT equivalent model equation based on blast wave of the explosion was used to analyze blast overpressure and impacts. Also, technical, systematic and managemental measure is described to ensure risk reduction for propulsion test facility.

This paper deals with the technical problems for the protection devices, by simulating test facilities of protection coordination for Photovoltaic systems. In order to analyze the operation characteristics for the protection devices in the case that the Photovoltaic systems with bi-directional power supply are located in the feeder, this paper proposes the test facilities composed of model distribution system, protection device and model Photovoltaic systems. By performing the simulation for operation characteristics for the protection devices based on the test facilities, this paper presents the malfunction mechanism for the protection devices. The test results show that this paper is practical and effective for the technical guideline for the Photovoltaic systems.

In distribution system about 5% of total outage is due to the lightning stroke. In order to reduce the rate of outage occurrence, distribution lightning protection equipments such as a secondary arrester, arching horn and various ground electrodes are developed and installed in the inside and outside of the county. Therefore it is needed to construct the test facilities to analyze the effect of these equipments. In this paper we describe the main content of the test facilities of lightning protection equipments. We have completed the field test of distribution lightning protection equipments for example lightning arrester, secondary arrester and arching horn etc.
