Objectives: Much scientific evidence indicate a positive association between moldy environments and respiratory illnesses and/or symptoms. However, few comprehensive assessments of mold have been performed for such settings. Spore counts or microscopic enumeration only may not be sufficient for evaluating fungal exposure. Recently, Mold Specific QPCR technology developed by the US EPA (Environmental Relative Moldiness Index, ERMI) has been widely used worldwide and great performance for assessing fungal exposure has been shown. Methods: We aimed to develop a Korean version of ERMI suitable for the distribution of fungal flora in Korea. Thirty dwellings in the Seoul and Incheon area were selected for sampling, and each was classified as 'Flooded, 'Water-damaged' or 'Non-water-damaged'. Results: Dust on the floor and airborne sampling were collected using an MAS100 and a 'Dustream' collector. Samples were analyzed by quantitative polymerase chain reaction(QPCR) for the 36 molds belonging to ERMI. Student t-test and ANOVA tests were carried out using SAS software. The median ERMI values of flooded, water damaged, and non-water damaged dwellings were 8.24(range: -5.6 to 27.9), 5.47(-25. 4 to 32.7), and -15.30(-24.6 to 14.8), respectively. Significant differences were observed between flooded and non-water damaged dwellings (P=0.001) and between water-damaged and non-water damaged dwellings (P=0.032). Conclusion: Our findings indicate that ERMI values attributed to dust samples in Korea could be applicable for the identification of flooded or water damaged buildings. However, much data is needed for continuously developing the Korean version of ERMI values.

As advances in computer technology, dissemination of smartphones and tablet PCs has increased and digital media has become easily accessible. The performance of computer hardware is improved and the form of hardware is changed, but basically the change in mechanism was not occurred. Typically, the data used in the program is resident in memory during the operation because of the operating system efficiency. So, these data in memory is accessible through the memory dumps or real-time memory analysis. The user's personal information or confidential data may be leaked by exploiting data; thus, the countermeasures should be provided. In this paper, we proposed the method that minimizes user's data leakage through finding the physical memory address of the process using virtual memory address, and initializing memory data of the process.

Purpose: The present study was conducted to develop the Life Respect Enhancement Program and test its effectiveness on suicide knowledge, suicide intervention skills, self-efficacy in suicide prevention, and gatekeeper behaviors among nursing officers. Methods: The program was developed according to the ADDIE model and finalized after practical need analysis, expert verification, and a preliminary study. The present study used a concurrent embedded mixed-method research design. To compare the effects of the Program and the control group on the outcome variables, a quantitative study was conducted using a nonequivalent control group with a pretest-posttest design. Quantitative data were analyzed using χ²-tests, t-tests, and RM-ANOVA. A qualitative study was conducted using FGI with six members of the experimental group 3 months after intervention completion. Results: In total, 56 nursing officers participated in the 3-month follow-up test. Compared to the control group, the experimental group showed significant improvements in suicide knowledge, suicide intervention skills, and self-efficacy in suicide prevention scores at post-test. The significant group differences in suicide knowledge and suicide intervention skills were maintained at 3 months. The gatekeeper behavior scores of the experimental group were also significantly higher than those of the control group at 3 months. Qualitative analysis of the participants' experiences with the Program yielded two themes and seven sub-themes. Conclusion: The newly developed Life Respect Enhancement Program demonstrates significant effects on suicide knowledge, suicide intervention skills, and gatekeeper behaviors. Thus, this program is recommended to promote suicide prevention competencies among nursing officers in military clinical settings.

Poly-Si is an essential material for floating gate in NAND Flash memory. To fabricate this material within region of floating gate, chemical mechanical polishing (CMP) is commonly used process for manufacturing NAND flash memory. We use colloidal silica abrasive with alkaline agent, polymeric additive and organic surfactant to obtain high Poly-Si to SiO2 film selectivity and reduce surface defect in Poly-Si CMP. We already studied about the effects of alkaline agent and polymeric additive. But the effect of organic surfactant in Poly-Si CMP is not clearly defined. So we will examine the function of organic surfactant in Poly-Si CMP with concentration separation test. We expect that surface roughness will be improved with the addition of organic surfactant as the case of wafering CMP. Poly-Si wafer are deposited by low pressure chemical vapor deposition (LPCVD) and oxide film are prepared by the method of plasma-enhanced tetra ethyl ortho silicate (PETEOS). The polishing test will be performed by a Strasbaugh 6EC polisher with an IC1000/Suba IV stacked pad and the pad will be conditioned by ex situ diamond disk. And the thickness difference of wafer between before and after polishing test will be measured by Ellipsometer and Nanospec. The roughness of Poly-Si film will be analyzed by atomic force microscope.

The study has piloted to find the Pattern of species distribution along environmental variables and disturbance in Raghunandan Reserve Forest. Shaltila and Shahapur beat of Raghunandan Hill Reserve Forest are situated in Chunarughat sub-district of Habiganj district between $24^{\circ}5^{\prime}-24^{\circ}10^{\prime}N$ and $91^{\circ}25^{\prime}-91^{\circ}30^{\prime}E$ under the Sylhet Forest Division. The Environmental variable and vegetation data were collected from 30 sample plots from each forest beat by using arbitrary sampling without preconceived bias. 51 species were found from Shaltila and 34 species found in Shahapur forest beat. Thus the dataset continued with total 85 species in 60 samples. To determine the relationships between tree species distribution and environmental variables, Canonical Correspondence Analysis (CCA) ordination method were performed separately for two forest beat. In CCA ordination, tree species showed significant variation along environmental gradients in terms of soil organic matter and disturbances (p<0.05) in the case of Shaltila forest. Potassium has a significant relationship with axis 1 and axis 2 in this forest. But Shahapur forest showed no significant relationship between species and environmental variables. Phosphorus has a significantly negative relationship with axis 2 in this forest. Disturbance played as a critical role of this forest thus influencing the distribution of species. The study showed that the distributions of tree species are strongly influenced by disturbance and organic matter in Shaltila and Shahapur forest beat showed no significant relationship between species and environmental variables. Future research should be included more environmental variables with larger study area that identify the most important environmental forces which will drive by species distribution findings in this forest.

Currently many people are concerned about 'Amusement With Prize(AWP)', together with the starting of Game Rating and Administration Committee (hereafter 'GRAC'). The mature-rated arcade games reproduced in reel game like the sea story in addition to main game and sub-game, causing social confusion in 2006, are waited for the reviewing of 'GRAC'. Although the game is reproduced in poker style as game system, in reel method as game graphic like 'AWP', the Supreme Court's decision is considered as a poker game May 23, 2013 in the past. Moreover, the Supreme Court said that it is not illegal because they decide that game users do not make a great loss in their possessions, without money change. The research tries to find the direction of the reviewing the mature-rated arcade game for guarantee of objectivity and reliability.
