A. oryzae 코오지로 담근 간장(SAO), M. pilosus-1 코오지 담근 간장(SMP) 및 이들 코오지를 50%씩 혼합하여 담근 간장(SAM)의 숙성 중 품질을 평가하였다. 90일간 숙성시킨 간장의 품질을 조사한 결과는 다음과 같다. pH는 SAO>SAM>SMP 순서로 SMP에서 가장 낮았다. SAO, SMP 및 SAM의 총 질소함량은 각각 1.15, 1.22 및 1.36%로 SAM에서 가장 높았다. SAM의 아미노태 질소함량은 0.78%로 SAO 및 SMP보다 높았다. 총 유리아미노산 함량은 SAO, SMP 및 SAM에서 각각 533.8, 732.4 및 807.3 ㎎/100 mL 이였다. SAO에서는 glutamic acid(65.20 ㎎/100 mL), SMP에서는 alanine(101.42 ㎎/100 mL), SAM에서는 glutamic acid(130.52 ㎎/100 mL)의 함량이 가장 높았다. 간장 숙성 중 protease와 β-amylase의 활성은 SAM에서 가장 높았으며, α-amylase활성은 SAO에서, glucoamylase의 활성은 SMP에서 가장 낮았다. Hue angle 값은 SAO 56.3, SMP 29.0, SAM 32.2 이였다. SMP 및 SAM의 monocolin K의 함량은 각각 6.21 및 3.10 ㎍/mL을 함유하였으며 HMG-CoA reductase에 대한 저해활성은 각각 21.5 및 10.2.%를 나타내었다. 색상, 냄새, 맛난 맛 및 종합적인 맛은 SAM에서 비교적 양호하였다. This study was conducted to evaluate the quality characteristics of different soy sauces. The soybean sauces brewed by the A. oryzae koji(SAO), M. pilosus-1 koji(SMP) and the mixture of 50% A. oryzae koji and 50% M. pilosus-1 koji(SAM) during 90 dyas fermentation. Total nitrogen contents of the SAM, SAP and SMP were 1.36%, 1.15% and 1.22%, respectively. Content of amino type nitrogen in SAM was 0.78%, and the content was higher than those of SAO and SMP. Total free amino acid contents of SAO, SMP and SAM were 533.8, 732.4 and 807.3 ㎎/100 mL. The highest contents of free amino acids were glutamic acid(65.20 ㎎/100 mL) in SAO, alanine(101.42 ㎎/100mL) in SMP, glutamic acid(130.52 ㎎/100 mL) in SAM. The highest activities of protease and β-amylase showed in SAM, and the lowest activities of α-amylase and glucoamylase were in SAO and SMP, respectively. Hue angle values showed 56.3 in SAO, 29.0 in SMP and 32.2 in SAM. Monacolin K contents, as inhibitor of cholesterol bio-synthesis were 6.21 ㎍/mL for SMP and 3.10 ㎍/mL for SAM, and the inhibitory activities of SMP and SAM against HMG-CoA reductase were 21.5 and 10.2%, respectiviely. Sensory scores for color, flavor, savory taste and overall taste of SAM was higher than those of SAO and SMP.

Four kinds of clays from Sinyewon mine which is located in Chungchoungnam-Do district and two kinds of Japanese clays (Gairome, Kibushi) were selected and studied on the fundamental properties of these clays and those which are refined by the elutriation method. Chemical analysis, grading analysis such as refractoriness, specific gravity, color, fired color and plasticity, particle size distribution, various thermal tests, X-ray diffraction analysis and electron microscopic survey were carried out on these clays. The comparison of domestic clays with Japanese clays was made. 1. In chemical composition and physical properties, these four kinds of Sinyewon clays are almost similar to each other and also to Gairome and Kibushi clays. In refractoriness, Gairome and Kibushi clays have relatively high value such as SK 34 and 35, while Sinyewon clays have the value of about SK 32. Especially Sinyewon clay B has the low refractoriness (SK 18) and plasticity. Refined clays have the tendency of somewhat higher value than crude ones in refractoriness. 2. When burnt up to $900^{\circ}C$, the coefficients of contraction of Sinyewon clays were under 1.5%, Gairome under 1.3%, Kibushi under 3.0%. Only Sinyewon clay B showed expansion (1.0%) instead of contraction. 3. X-ray diffraction analysis and electron micrography showed that all of four Sinyewon clays and two Japanese clays are mainly composed of poorly crystallized kaolin, containing small amount of halloysite, sericite and considerable amount of quartz and feldspar. Sinyewon clay B contains especially large amount of quartz and feldspar. In general, it has been found out that the refined clays were free from large amount of iron oxide, quartz and feldspar.

Program evaluation with validity is known to be a difficult task even for experienced researchers. This paper is prepared by a staff and students of public health evaluation course offered to doctorate students as a part of practice in evaluative research. In order to practice the principles of evaluative research, and to assess current Korean status of this area, eighteen papers dealt with public health concerned program evaluation in three different subjects, i.e., demonstration program of Korea Health Development Institute(KHDI), community health demonstration programs of universities and family planning program of Korean government, were reviewed. Suchman's principles of evaluative research were applied mainly as a standard reference; formulation of objectives by level, validity of underlying assumptions for each objective, suitability of research design, use of evaluation categories with correct concept, verification of data in terms of its valitidity and reliability, and utility of evaluation results. Most of these evaluative researches were formative evaluations but one summative evaluation, the KHDI health program, and the type of evaluation was all goal-oriented approach. Generally evaluation principles have been applied poorly in most cases applying only a part; mostly effort, and some parts of performance and process. In some papers, these were no statements on evaluation objectives. Also underlying assumption in formulating objectives have rarely been stated, verification of data were very poor, and only few papers have dealt with all five categories of evaluation including adequacy of performance and efficiency of the program subjected to evaluation. Thus it was concluded that further effort should be given to the training public health personnel on evaluative research methodology with emphasis on practical and correct application of the evaluation principles.
