This study is to organize the frame of measuring inventory for housing quality related to mental health in foreign literature reviews. In the first step, many housing quality contents or items are extracted from empirical studies, including housing environment quality and mental health. In the next step, extracted contents and items are classified by space scope (house and neighborhood unit) and WHO housing properties (safety & security, health & sanitation, efficiency/convenience, comfort/amenity). Almost all housing properties follow the WHO standard, but some properties, sustainability and economic characteristics, do not follow the standard. These reflect on current Korean housing environment. They are energy saving and environment friendly effort, property value and economic burden, identity expression, and school district. So they need to be added to the Korean housing quality measurement related to mental health.

베트남은 화력발전을 중심으로 한 발전용량 확보 계획을 추진 중이며, 석탄화력발전소로부터 배출되는 석탄재의 대량처리 방안 확보가 시급한 실정이다. 이 연구는 베트남에서 발생하는 석탄재 중 미연탄소 함량이 높아 재활용이 어려운 저품위 비산재의 미연탄소 함량을 국제 비산재 활용기준인 6% 미만으로 낮추는 것을 목표로 하였다. 저품위 비산재를 배출하는 발전소의 비산재 품질을 조사한 결과, 비산재의 미연탄소 함량은 5.3~23.6%로 미연탄소 함량이 높고 불규칙하였다. 공기분급과 정전선별을 적용하여 비산재를 처리한 결과, 미연탄소 함량 9.8%까지는 분급 단일공정으로, 23.6%까지의 비산재는 분급과 정전선별로 구성된 복합공정으로 미연탄소 함량을 6% 미만으로 감소시킬 수 있었다.

The production and authoring of digital multimedia contents are most important fields in multimedia technology. Nowadays web-based technology and related multimedia software technology are growing in the IT industry and these technologies are evolving most rapidly in our life. The technology of digital audio and video processing is utilizing rapidly to improve quality of our life, Also we are more interested in high sense and artistic feeling in the music and entertainment areas by use of three dimensional (3D) digital sound technology continuously as well as 3D digital video technology. The service field of digital audio contents is increasing rapidly through the Internet. And the society of Internet users wants the audio contents service with better quality. Recently Internet users are not satisfying the sound quality with 2 channels stereo but seeking the high quality of sound with 5,] channels such as 3D audio of the movie films. But it might be needed proper hardware equipments for the service of 3D sound to satisfy this demand. In this paper, we expand the simple 3D audio generator developed and propose a web-based music bank by the software development of 3D audio generation player in 3D sound environment with two speakers minimizing hardware equipments, Also we believe that this study would contribute greatly to digital 3D sound service of high quality for music and entertainment mania.

In order to study the general characteristics of reservoir and stream sediments, various analysis tests were conducted. Water contents and ignition loss were measured to know the primary sediment characteristics. The COD, total phosphorus and nitrogen were contained for the determination of organic substance content. For the purpose of establishing the contamination degree of heavy metals, some heavy metal contents were investigated. In heavy metal contents, reservoir sediments showed somewhat higer value than stream sediments. As a result, the reservoir sediment content of all analysis items were higher than stream sediment.

Demand for organic agriculture has greatly increased in the past decade. The objective of this study was to evaluate quality the characteristics and antioxidant activities of organically and conventionally grown carrots. Organically and conventionally grown carrots were harvested in Jeju Island, Korea. Carrot extracts were investigated for their antioxidative components (total phenolic and flavonoid contents) and their antioxidant activities (DPPH and ABTS radical scavenging activities). The quality characteristics of carrots were estimated in terms of hardness, length, weight, moisture contents, and soluble solid content (SSC). Conventionally grown carrots showed higher values than organic carrot in terms of hardness (p<0.05), but there was no significant difference in moisture contents or SSC. In the case of antioxidant activity, organic carrots showed a higher value for DPPH radical scavenging activity (p<0.05). However, there was no significant difference in other antioxidants. Consequently, quality characteristics and antioxidant activities were different between organically and conventionally grown carrots.

This study was conducted to develop a salad dressing using Prunella vulgaris L. (PV) extracts. In addition, the study was also aimed at evaluating the quality characteristics of the salad dressing containing various amounts of PV extracts. Salad dressing was prepared by adding 0% (PD-0), 9.4% (PD-20), 18.8% (PD-40), 28.2% (PD-60), 37.6% (PD-80), 47.0% (PD-100) of PV extract. The quality characteristics (sugar contents, salinity, color value, total phenol contents, total flavonoid contents, DPPH, ABTS+ radical scavenging activities, and sensory acceptability) of the dressing were analyzed. According to the results of the study, the sugar contents and salinity of salad dressing increased according to the added amount of PV extract (p<0.001). The color values of lightness and yellowness of salad dressing increased according to the added amount of PV extract, whereas color value of redness decreased (p<0.001). Antioxidant activities were improved depending on the amount of PV extracts (p<0.001). The sensory acceptability (flavor, medicinal flavor, saltiness, sourness, bitterness and viscosity) were significantly higher in the dressing added with 18.8% PV extracts than in the other samples. Based on this result, a storage experiment was conducted by comparing PD-40 and PD-C. After 4 weeks of storage at $4^{\circ}C$ and $24^{\circ}C$, the quality characteristics were observed and the pH was increased in the later stages of storage (p<0.05). The depicted that, viscosity increased with storage time at $4^{\circ}C$ (p<0.001). General bacteria and coliform were not detected during storage. These results indicated that salad dressing with the addition of 18.8% PV extracts has the best quality.

지방자치제도가 활성화되고 있는 시점에서 지역주민은 지방자치단체 행정의 집행에 있어서 수동적인 객체가 아니라 행정서비스를 평가하고 능동적으로 구매하는 고객으로 인식되고 있다. 본 연구에서는 지역주민을 대상으로 하여 복지정책, 산업정책, 교육문화정책, 생활환경정책 등 다양한 분야별 정책콘텐츠에 대한 만족도를 측정하여 분석하고자 한다. 분석결과 보건복지정책, 교육문화정책콘텐츠를 제외한 나머지 분야에 대해서는 만족도가 낮은 것으로 나타났다. 이러한 결과를 바탕으로 정책적 제언을 제시하고 있다.

본 연구는 디지털 매체를 통한 고전문학의 원소스 멀티유즈(One Source Multi Use)의 활성화를 위해 매체품질에 대해 고찰하였다. 한국향토문화전자대전(www.grandculture.net)(향토DB)는 전국 234개 시 군 구의 향토문화 자료와 함께 설화, 민요 등이 구축되어 있어 고전문학의 OSMU가 가능한 매체이다. 이에 IS 성공모형을 적용하여 향토DB의 매체품질이 학습만족을 매개로 지속이용의도에 미치는 영향을 고찰하고자 고전문학수업을 받은 418명의 고등학생을 대상으로 설문조사를 실시하고 구조방정식을 사용해 분석하였다. 그 결과, 향토DB의 콘텐츠품질과 서비스품질은 학습만족을 매개로 지속이용의도에 영향을 미쳤으나 시스템품질의 학습만족에 대한 영향은 나타나지 않았다. 탐색적 다중회귀분석 결과, 시스템품질을 높게 인식하는 집단에서는 시스템품질의 학습만족에 대한 영향이 통계적으로 유의미하였으나 시스템품질을 낮게 인식하는 집단에서는 시스템품질의 학습만족에 대한 영향이 나타나지 않았다. 이러한 결과는 향토DB의 시스템품질이 향상되면 학습만족은 조금 강화되는 반면 콘텐츠품질과 서비스품질이 향상되면 학습만족은 상당히 활성화될 것임을 의미한다.

This study was investigated that quality inspection of distributed Scutellariae Radix in Korea. To evaluate the quality of these herbal medicines, we carried out TLC pattern, foreign matter in purity, loss on drying, ash, acid-insoluble ash, oil content, dilute ethanol-soluble, water-soluble, ether-soluble extracts contents, quantitative analyses, residual $SO_2$, individual heavy metals and organochlorine pesticides. To measure contents of baicalin, baicalein and wogonin, we were quantitative analyzed using HPLC. The average contents of baicalin, baicalein and wogonin were detected by 13.28 (${\pm}$0.43)%, 1.17 (${\pm}$0.04)% and 0.40 (${\pm}$0.02)%, respectively. Each average contents As, Cd, Hg and Pb was 0.059 (${\pm}$0.054) mg ${\cdot}$ $kg^{-1}$, 0.019 (${\pm}$0.010) mg ${\cdot}$ $kg^{-1}$, 0.017 (${\pm}$0.057) ppm and 0.242 (${\pm}$0.084) mg ${\cdot}$ $kg^{-1}$, respectively.
