This study investigated factors affecting care for elderly patients, management of systemic disease, infection management, improvement of medical care quality, and educational requirements, and provide basic data for quality care for elderly patients with systemic diseases. An online survey was conducted among dental hygienists working at dental institutions and data of 172 individuals were analyzed using the SPSS 21.0 program. Descriptive statistics was performed for general characteristics. For factor analysis by general characteristics, t-test and ANOVA were performed. For differences between groups Scheffe verification was performed. A correlation analysis between factors was performed using Pearson's correlation analysis, and a factor analysis affecting the improvement of healthcare quality was performed using multiple linear regression analysis. Care for elderly patients was 52.33/75, management of systemic disease was 12.65/17, and infection management was 96.92/130. Improvement of medical quality (institutional effort) was 22.87/35, and improvement of medical quality (personal effort) was 22.72/35. The most common educational needs were "necessary". Analysis revealed a positive correlation between factors.. Factors affecting improvement of medical quality (personal effort) were age, final academic background, place of work, and the presence or absence of annual medical examinations. The findings of this study indicate that there is a significant correlation between factors. For the qualitative care of elderly patients, education programs related to elderly characteristics, systemic diseases, and infection management should be actively conducted by dental hygienists, and interest and research on geriatric dental hygiene is needed, centering on associations and educational institutions.

This study was carried out to increase the efficiency of site investigation through the evaluation of the applicable methods of investigation for cutting slope design. In an effort to find out the applicability of the method employed during the slope investigation, some tests were carried out on 6 subjects i.e location of weak zones, characteristics of discontinuities, distribution of strata, in situ tests for geo-technical properties, laboratory test and estimation of weathering. The method was highly applicable and produced expected results during the test of weak zones, discontinuities and distribution of strata. In order to apply the method to in- situ test for geo-technical properties and laboratory test on soil and rock slope, a statistic analysis of the existing data were required in advance. However its design applicability on rock slope was good although actual cases of application were not many due to limitation of the cases for investigation. The method was frequently referenced but not actually applied for anti seismic design test and estimation of weathering.

This paper describes the verification test on Electromagnetic Environmental Effects(E3), which conducted on ground as a final step to confirm the normal operation of ELINT pod and Safety-of-Flight of KF-16C/D mounted with ELINT pod prior to the initial flight. Based on MIL-STD-464A, indispensable 7 requirements among 14 detailed requirements total were carried out in the test. Considering the Safety-of-Flight(SOF), we invest a great deal of time and effort on Hazards of Electromagnetic Radiation to Ordnance(HERO) and Intra-system EMC test. E3 test and evaluation were performed on 62 equipments of KF-16C/D, respectively. As a result, we verify that KF-16C/D mounted with ELINT pod(hereafter "system") are electromagnetically compatible among all subsystems and equipment within the system and with environments caused by electromagnetic effects external to the system.

Recently, a software program has been used in nuclear power plants (NPPs) to digitalize many instrumentation and control systems. To guarantee NPP safety, the reliability of the software used in safetycritical instrumentation and control systems must be quantified and verified with proper test cases and test environment. In this study, a software testing method using a simulation-based software test bed is proposed. The test bed is developed by emulating the microprocessor architecture of the programmable logic controller used in NPP safety-critical applications and capturing its behavior at each machine instruction. The effectiveness of the proposed method is demonstrated via a case study. To represent the possible states of software input and the internal variables that contribute to generating a dedicated safety signal, the software test cases are developed in consideration of the digital characteristics of the target system and the plant dynamics. The method provides a practical way to conduct exhaustive software testing, which can prove the software to be error free and minimize the uncertainty in software reliability quantification. Compared with existing testing methods, it can effectively reduce the software testing effort by emulating the programmable logic controller behavior at the machine level.

AUTOSAR, a standard software platform for automotive, has been developed to manage software complexity and improve software reuseability. However reuse of test system is difficult because it is dependant on implementation language and test phase. In this paper, we suggest a test system generation method for AUTOSAR software component using TTCN-3, a standardized testing language. TTCN-3 test system is generated automatically from AUTOSAR XML containing software design information. The test system consists of TTCN-3 tester and target system and tests functionality and worst case response time of software under simulation environment. With the proposed testing techniques we can reduce time and effort to build the testing system and reuse testing environment.

Rapid loss in viability of neem (Azadirachta indica A. Juss.) seed is a major problem. Present effort was undertaken for developing a set pattern for assessing of viability and vigour in seed of various mother tree age of neem (Age I-06 years, Age II-15 years, Age III-25 years and Age IV->30 years old). Various viability test viz. triphenyle tetrazolium chloride test, electrical conductivity, excised embryo test, and germination test have been performed on seeds obtained from mother tree age classes. Inconsistency was observed with the TTC and EC test in germination of seed in laboratory as well as nursery. While various vigour tests viz. cold test, chemical stress test (methanol stress test), and accelerated ageing test alongwith ageing index, germination test (G%, MGT and GV) and various seedling growth parameters like seedling length (cm), number of leaves, collar diameter (cm), total biomass (g) alongwith mathematical indices i.e. vigour index, sturdiness quotient, volume index, quality index, root shoot ratio in nursery as well have been taken for study and showed better consistency. On the basis present study results of various viability and vigour test indicated that mother tree age class II performed better in comparison to others and it can be recommended for seed collection. Further it is also recommended that viability of neem seed may be assessed using various laboratory tests like excise embryo test and germination test (G%, MGT and GV) and vigour test may be taken preferably by cold germination test, chemical (methanol) stress test, accelerated ageing test in laboratory and germination alongwith various seedling growth parameters seedling length (cm), number of leaves, collar diameter (cm), total biomass (g) alongwith mathematical indices like Vigour Index, Sturdiness quotient, Volume Index, Quality index, root shoot ratio in nursery as discussed in this study.
