최근, 산업부산물의 재활용과 이산화탄소 저감은 사회적으로 매우 중요한 이슈이다. 이러한 측면에서 화력발전소에서 발생되는 석탄회는 콘크리트의 혼합재로 사용되는 것이 재활용 방안 중 최선으로 알려져 있다. 석탄회를 콘크리트에 사용하기 위하여 KS에서는 $SiO_2$, 분말도, 비중, 강열감량 및 활성도 지수 등의 품질 항목을 선정하여 관리하고 있다. 특히, 활성도 지수의 경우는 석탄회가 콘크리트에 사용될 때의 강도 발현성을 판정할 수 있는 가장 주요한 판정기준인데 반해서 실험소요 기간이 최소 28일 혹은 91일이 요구되는 단점을 가지고 있다. 이러한 문제점에 착안하여 본 연구에서는 기존 활성도 지수를 대체하여 석탄회의 포졸란 반응성을 신속하게 측정할 수 있는 API 시험법을 적용하여, API 시험결과와 활성도지수 및 K-value와의 비교 분석을 통하여 API 시험법의 적용 가능성을 검토하고, 신속 측정방법인 API 시험법에 의한 국내 석탄회의 품질을 평가하고자 하였다. 실험 결과, 국내 석탄회는 수분 및 비중을 제외하고는 KS 품질기준을 대부분 만족하지 못하는 것으로 나타났으며, 특히 유동층 보일러 애시는 고유의 특성을 가지는 것으로 나타났다. API와 활성도지수 및 K-value의 경우, 각각의 상관성이 상당히 좋은 것으로 나타났다. 특히, 재령이 증가할수록 API와의 상관성은 점점 증가하는 것으로 나타나 장기 재령의 실험을 요구하는 활성도 지수 대신에 2일 내에 결과를 알 수 있는 API시험이 석탄회의 포졸란 반응성 평가에 매우 유용한 시험방법인 것으로 판단된다.

본 연구는 제주특별자치도 내 실적공사비가 적용된 도로현장을 중심으로 물가변동에 따른 실적공사비 등락률 산정의 문제점을 분석하기 위하여 실시되었다. 본 연구를 위하여 제주특별자치도 내 9개 도로공사 현장을 중심으로 실적공사비방식, 표준품셈방식, 건설공사비지수방식에 따른 등락률을 비교 분석하였다. 분석결과 9개 현장 중 약 56%인 5개 현장에서 실적공사비의 지수조정률이 표준품셈과 건설공사비지수의 지수조정률에 비해 낮게 산정되었다. 이는 실적공사비가 적용됨에 따라 물가변동으로 인한 계약금액 조정 성립요건이 지연되고 있다는 것을 알 수 있으며, 이에 따라 공사 준공 전 물가변동으로 인한 계약금액 조정횟수의 감소와 함께 물가변동금액 역시 차이를 보일 수 있음을 의미한다. 또한, 건설공사비지수 사례분석 결과, 도로부문에 대한 지수를 적용하여 지수조정률을 산출하였으나 지수조정률이 2.0%~9.4%까지 산정되어 이는 공사금액 및 물가변동 적용시기에 따라 상당한 영향을 미치는 문제점이 나타났다.

Biodiversity refers to the diversity of organisms originating from all sources, including terrestrial ecosystems, aquatic ecosystems, and complex ecosystems and it is considered to be the standard of the area to be preserved and protected. So The Importance of environmental assessment for biodiversity conservation is increasing and International efforts to quantify biodiversity and to develop indices have been made, but there are insufficient researches on the use of biomass databases and their quantification in Korea. In this study, the biodiversity map was constructed using the 3rd National Ecosystem Survey Mammal Data with three spatial units(Administrative Area, 1:5,000 index map, hexagonal lattice). and the difference of map constructed by spatial unit was suggested to help research on quantification and evaluation of biodiversity in the future. As a result of the study, biodiversity index for the same area varied according to the spatial unit and overall average and standard deviation were different too. Therefore it is necessary to utilize appropriate spatial unit considering the suitability and purpose of quantification rather than using specific unit. It also showed the necessity of establishing a standard for biodiversity index as a result of comparative analysis with ecosystem and nature map. Based on this research, comprehensive efforts should be made for the sustainable development of the country through further research and institutional improvement for quantification and evaluation of biodiversity, set standards.

This report is the second study to develop the standard tables of body measurements to be used for improving the fit of garments and patterns for women aged 60 and older. The purpose of this study is to suggest the new sizing system proper to the women aged 60 and older by classifying their somatotype and developing the standard tables of body measurements for each somatotype. The data are the anthropometric measurements of 329 women aged 60 and older measured in 2001 and the 1997 National Somatometry Survey data. The major contents of this study are as follows. The applicability of KS K 0051 and ISO 3637 sizing systems to the women aged 60 and older was investigated by analyzing the distribution of height and drop index the difference of hipgirth and bustgirth. In this result, we certified the two sizing systems were not so proper to elderly women and the new sizing system proper to them was required. So, we classified the somatotype of the women aged 60 and older to 3 groups, 135cm$\leq$H(height)＜145cm, 145cm$\leq$H＜155cm, 155cm$\leq$H＜165cm by height and classified to 3 groups, -4cm$\leq$D(drop)＜16cm, -4cm$\leq$D＜4cm, -l6cm$\leq$D＜-4cm by drop index, and we suggested more proper sizing system for women aged 60 and older by compounding height and drop groups. We also developed the standard tables of body measurements every bustgirth groups of 9 somatotypes. We expect the standard tables of body measurements to applicate to manufacture clothing for elderly women.

Purpose: Despite the high success rates of endosseous dental implants, their placement is restricted according to the height and volume of bone available. The use of short or mini dental implants could be one way to overcome this limitation. Thus, this study aimed to compare standard, short, and mini dental implants with regard to associated clinical parameters and peri-implant crevicular fluid (PICF) levels of cathepsin-K (CTSK), RANK ligand (RANKL), and osteoprotegerin (OPG), after prosthodontic loading. Methods: A total of 78 non-submerged implants (Euroteknika, $Aesthetica^{+2}$, Sallanches, France) were installed in 30 subjects (13 male, 17 female; range, 26-62 years) who visited the clinic of the Periodontology Department, Faculty of Dentistry, Selcuk University. Sampling and measurements were performed on the loading date (baseline) and 2, 14, and 90 days after loading. Assessment of the peri-implant status for the implant sites was performed using the pocket probing depth (PPD), modified plaque index, modified gingival index, modified sulcular bleeding index, and radiographic signs of bone loss. PICF samples collected from each implant were evaluated for CTSK, RANKL, and OPG levels using the ELISA method. Keratinized tissue and marginal bone loss (MBL) were also noted. Results: Clinical parameters statistically significantly increased in each group but did not show statistical differences between groups without PPD. Although implant groups showed a higher MBL in the upper jaw, only the standard dental group demonstrated a statistically significant difference. At 90 days, the OPG:sRANKL ratio and total amounts of CTSK for each group did not differ from baseline. Conclusions: Within the limitations of this study, both short and mini dental implants were achieving the same outcomes as the standard dental implants in the early period after loading.

This study evaluates the effectiveness of the "Seoul Sanitation Grading System Evaluation Index" developed earlier and to analyze sanitation management practices in restaurants in Seoul, Korea. The categories evaluated were the food management standard, facilities/equipment standard, and essential checking items specified in the law. These items were graded and classified into A ($100{\sim}90$), B ($89{\sim}80$), C ($79{\sim}70$) and Score (less than 69) based on the criteria set by the present researchers. We randomly selected 56 restaurants in five local cities (Jung-gu, Seocho-gu, Jongno-gu, Songpa-gu and Yeongdeungpo-gu) and investigated each by actually visiting the site of business. The achievement rate for food management standard was 80.8%; as for the specific items in the category, it was the highest in food ingredients at 77.1% and the lowest in food storage at 62.1%. For the facilities/equipment standard, the achievement rate was 77.8%; as for the specific items in the category, it was the highest for vermin at 88.1% and the lowest for operation at 70.8%. The achievement rate for overall individual sanitary management was 70.7% and in the category, the lowest score was seen in hand washing at 57.1%. The overall average score of sanitation management practices using the Seoul Sanitation Grading System Evaluation Index in restaurants in Seoul was 73.7, which fell into the C category. As for the number of restaurants in each grade category, there were 10 (17.9%) in each category of A ($100{\sim}90$), B ($89{\sim}80$) and C ($79{\sim}70$) with 30 (53.6%) scoring higher than 70, whereas those scoring less than 69 included 26 (46.4%). The average scores for those restaurants designated by local governments (exemplary restaurants, general restaurants, best Korean restaurants in Seoul) were not significantly different; however, they were higher in franchises than those small restaurants ran by individuals.
