통제된 실험실에서 자연스런 정서음성을 수집하기 위하여 자전적 회상 방법이 시용되었다. 16명의 대학생에게 행복, 화, 슬픔, 두려움을 가장 강하게 경험한 과거 사진을 회상하도록 하였고, 비교집단으로서 4명의 연극배우에게는 스스로 감정 상태에 몰입하게 하였다. 3명의 독립적 평정자들이 피험자들의 얼굴 표정과 음성 특징을 평가하였다. 대학생들의 유도된 음성과 배우들의 음성을 비교한 결과, 자전적 회상 방법은 미묘한 감정적 단서를 전달하는데 효과적으로 평가되었으며 배우들이 모사한 음성은 더 극단적인 정서를 표출하는 것으로 평가되었다. 정서음성 수집에 있어서 자전적 회상 방법이 가지는 함의와 이 방법의 잠재적인 문제점도 논의되었다. In order to obtain natural emotional voice in laboratory, an autobiographical recall method was used and happy, angry, sad and afraid feelings were induced in 16 college students. Three independent judges rated the subject's facial expressions and vocal characteristics. The mood induction results were compared with those from the actor-initiated method. Data analysis showed that recall-induced voices successfully conveyed subtle emotional cues, while actor-induced voices signaled more extreme emotioms. Implications of the autobiographical recall method in emotional voice research and potential problems are discussed.

Objective: This study aimed to compare the characteristics of humidifier disinfectant-like products (HD-like products) and humidifier disinfectant products (HD products) and introduce actual cases of the usage of HD-like products in hospitals based on an on-site investigation. Methods: The characteristics, chemical components, and usage of HD-like products (Hichlor or Biospot) and HD products (N-with) containing NaDCC (sodium dichloroisocyanurate) were compared. In the process of conducting the on-site investigation, four hospitals were identified as previously using HD-like products. Each on-site investigation to identify the use of HD-like products was composed of four parts: 1) hospital infection control guidelines, 2) manual for humidifiers in patient’s rooms, 3) interviews with nursing staff, infection managers, and purchase managers, 4) searching on the product purchase system. Results: Although HD-like products (Hichlor and Biospot) and HD products (N-with) were sold for different usage purposes, they were all white-colored and coin-shaped foaming tablets with the same chemical component, NaDCC. The manual for using HD-like products and HD products was similar (inserting the tablet in a humidifier container with water). Among the four hospitals, one had used Hichlor in the same manner as HD (N-with) by inserting a tablet in 1L of water in a filled humidifier container and Biospot as a kind of detergent for humidifier container cleaning. Another two hospitals had used Biospot and/or Aniosyme as a kind of detergent for humidifier container cleaning. The other hospital had used unknown product in the same manner as N-with, so we thus assumed it was either an HD products (N-with) or HD-like products (Hichlor, Biospot). Conclusion: This study raises the possibility of the development of adverse health effects similar to exposure to an HD-products when exposed to an HD-like products and the possibility of further use in other medical institutions or multi-use facilities. Therefore, an expansion of the investigation is needed in order to confirm whether there have been similar cases in the past.

Background: This study purposed to analyze the relationship between spatial distribution of Diabetes prevalence rates and regional variables. Methods: The unit of analysis was administrative districts of city·gun·gu. Dependent variable was the age- and sex- adjusted diabetes prevalence rates and regional variables were selected to represent three aspects: demographic and socioeconomic factor, health and medical factor, and physical environment factor. Along with the traditional ordinary least square (OLS) regression analysis, geographically weighted regression (GWR) was applied for the spatial analysis. Results: Analysis results showed that age- and sex-adjusted diabetes prevalence rates were varied depending on regions. OLS regression showed that diabetes prevalence rates had significant relationships with percent of population over age 65 and financial independence rate. In GWR, the effects of regional variables were not consistent. These results provide information to health policy makers. Conclusion: Regional characteristics should be considered in allocating health resources and developing health related programs for the regional disease management.

This study examined Korean juvenile offenders’ experience of police investigative interviewing as suspects and their level of Miranda warnings. Questionnaire survey was conducted for 102 juvenile offenders at a local juvenile detention facility. Most juvenile offenders(93.1%) reported that they confessed during police investigative interview interviewing but far less of them had enough opportunity to speak for themselves. Juvenile offenders expected that investigators would think they were guilty or uncooperative if they did not waive their right to silence. The average comprehension level of Miranda warnings as measured in sentence recognition tests was 66.9%. Implication of these findings and limitations of this study are discussed.

Statistical process control techniques have been greatly implemented in industries for improving product quality and saving production costs. As a primary tool among these techniques, control charts are widely used to detect the occurrence of assignable causes. In most works on the control charts it considered the problem of monitoring the mean and variance, and the quality characteristic of interest is normally distributed. In some situations monitoring of the minimum and maximum values is more important and the quality characteristic of interest is the Weibull distribution rather than a normal distribution. In this paper, we consider the statistical design of minimum and maximum control charts when the distribution of the quality characteristic of interest is Weibull. The proposed minimum and maximum control charts are applied to the wind data. The results of the application show that the proposed method is more effective than traditional methods.

본 논문에서는 ZrO₂에 Y₂O₃을 도핑하여 유전 상수를 향상시키는 방법을 제안한다. Yttrium-doped Zirconium 박막은 고농도로 도핑된 p형 실리콘 위에 spin coating 방식으로 제작되었다. ZrO₂에 Y₂O₃의 도핑 농도를 1:8, 1:4, 1:2로 변경하여 전기적 특성을 분석하였다. 그 결과, 도핑 농도가 증가할수록 유전 상수는 증가하였고, 누설 전류는 0.25 MV/cm 기준 ZrO₂에 Y₂O₃의 도핑 농도가 증가할수록 감소하였다. 그리고, 주파수에 따른 capacitance를 분석한 결과, Y₂O₃을 도핑하기 전과 후 전반적으로 주파수에 따른 capacitance 변화가 작은 특성을 가져 안정적임을 확인하였다. 따라서, Yttrium-doped Zirconium이 SiO₂를 대체할 차세대 게이트 산화막의 유망한 후보임을 보인다.

어성초(H. cordata Thunb) 건조 분말(0.05 g)을10 mL의 증류수와 함께 스테인리스 용기에 넣고 밀봉한 후 여러 온도(50, 100, 200, 300℃)에서 10, 30, 60분간 추출하였다. 추출온도와 시간은 어성초 추출물의 중요성분, 항산화 활성, acetylcholinesterase 저해 활성에 크게 영향을 미쳤다. 300℃에서 30분간 처리한 어성초 추출물에서 가장 높은 페놀함량(33.34±0.96 μg gallic acid equivalents/mL), quercetin 함량(15.75±0.20 μg/mL), DPPH 라디칼 소거능(44.07±2.65%), acetylcholinesterase 저해 활성(36.53±1.14%)이 나타났다. 플라보노이드 함량은 100℃ 10분 추출물에서 2.55 μg quercetin equivalents/mL로 가장 높게 측정되었다. 100℃ 이상의 고온에서 밀폐된 증류수는 높은 압력에서 아임계수 형태로 존재하는데 이러한 아임계수는 고품질의 어성초 추출물을 제조하는데 매우 유용하였다. Houttuynia cordata Thunb powder (0.05 g) was placed in a stainless vessel containing 10 mL of water, and subcritical water (SCW) extraction was carried out at various temperatures (50, 100, 200, and 300℃) for 10, 30, and 60 min. SCW treatment significantly affected physiologically important compounds, antioxidant activity, and acetylcholinesterase inhibitory activity of H. cordata Thunb extracts. H. cordata Thunb extracted at 300℃ for 30 min had the highest quercetin content, DPPH radical scavenging activity, total phenolic content, and acetylcholinesterase inhibitory activity, whereas the extract at 100℃ for 10 min possessed the highest flavonoid content. The highest ABTS radical scavenging activity was found in H. cordata Thunb extracted at 200 and 300℃ for 60 min. These results indicate that SCW extraction might be a useful processing method for obtaining valuable materials from H. cordata Thunb.

In general, the vibration problems for strength of members and serviceability of building structures are not considered in structural design process, but the prediction of the vibration is very important and essential to structural design process. Especially, it is necessary to design the structure with precise machinery such as wafer, electronic microscope. To predict the vibration response of the floor, it is necessary to know various excitation forces and dynamic characteristics of the floors. This study aims to predict the dynamic forces and vibration responses of the floor in terms of the transfer function method on the rahmen building structures. In order to know the dynamic forces and vibration responses, the modal test and the impact(impact hammer) excitation experiments were conducted several times on the floor. The results from the experiments are analyzed and compared with the measured excitation forces and vibration results. The results of this study suggest that the predicting the dynamic forces and vibration levels using transfer function method is possible to the extent of it.
