  • Looking at the dietary patterns of women in their 20s and 30s as well as postmenopausal women, the intake of most nutrients was lower than the recommended levels. Shrimp is a low-calorie, high-protein food, and contains abundant minerals, and it is expected to help prevent osteoporosis. In this study, jinmal dasik was prepared by varying the shrimp content at 0, 1, 5, and 7%, and the quality characteristics were measured. Hardness, adhesion, chewiness, and cohesiveness of physical properties increased significantly as the amount added increased (p<0.001). The springiness decreased significantly as the amount of addition increased in the addition group (p<0.001). In the calcium, there was a significant increase as the amount added increased (p<0.001). In the potassium, there was a significant increase as the amount added increased (p=0.049). This study intends to highlight the benefits and possible uses of shrimp.

  • 상황인식컴퓨팅은 환경에 대한 시의적절한 반응을 위해 필요한 정보를 자동적이고 효율적으로 인식하기 위한 연구 분야로서 안전, 상거래, 의사결정지원시스템 등 다양한 영역에서 응용되고 있다. 이러한 응용분야 중 상당수는 개인 차원뿐 아니라 집단 수준의 상호작용도 지원해야 한다. 효과적인 집단 상호작용을 위해서는 집단 역학과 같은 특수 현상을 고려해야 하며 이를 위해서는 역할, 갈등, 권력, 규범 등과 같은 집단의 속성을 정확하게 파악해야 한다. 그러나 지금까지의 상황인식컴퓨팅은 개인 상황에 집중되어 있고, 집단만이 가지는 고유한 상황 정보에 대한 인식 연구는 그 필요성에도 불구하고 많이 않다. 따라서 본 연구의 목적은 집단 상황(group context)을 자동으로 인식하는 방법을 새롭게 제안하는 것이다. 특히 본 논문에서는 집단 응집성의 인식에 집중하고자 한다. 이를 위해 물리적 센서(physical sensors) 또는 논리적 센서(logical sensors) 로 측정 가능한 요소를 활용한 사례기반 추론 방법을 제안하였다. 본 논문의 방법론의 적용 가능성을 보이기 위해 실험을 실시하여 기존의 집단 응집성 측정 방법과 비교하여 성능을 검증하였다.

  • We studied the antioxidant activities and quality characteristics of gelatin jelly prepared with different amounts (0%, 0.25%, 0.50%, and 0.75%) of Rehmannia Radix Preparata (RRP) concentrate. The moisture content of the control group was 61.62%, and the acidity and pH were 3.68 and 1.96%, respectively. The reducing sugar content of the jellies ranged from 10.83% to 13.1% (from 35.0 $^{\circ}Brix$ to 37.0 $^{\circ}Brix$). The acidity of the control group was the lowest, followed in order by the 0.25% RRP, 0.50% RRP, and 0.75% RRP groups. The lightness, redness, and yellowness of the Hunter color system decreased with increasing RRP concentrate, whereas the hardness, cohesiveness, and springiness increased with increasing concentrate. The total phenol content was the highest in 0.75%. Antioxidant activities such as DPPH radical scavenging and hydroxyl radical scavenging were the highest with the 0.75% group ($IC_{50}$ value of DPPH radical scavenging activity: 85.42 mg/mL for 0.75%, 484.25 mg/mL for control; $IC_{50}$ value of hydroxyl radical scavenging activity: 54.42 mg/mL for 0.75%, 135.54 mg/mL for control). The sensory evaluation results showed that overall preference and texture were the highest in the 5% addition group. From these results, it was suggested that the optimum amount of RRP concentrate to add to jelly is 0.50%.

  • To evaluate the effect of Ulmus davidiana powder on rice dasik, Ulmus davidiana dasik was made after supplementation with Ulmus davidiana powder(0, 3, 6, 9 and 12%(all w/w)). The proximate component of Ulmus davidiana powder was 7.49% moisture content, 2.33% crude protein, 0.84% crude fat, 14.09% crude fiber and 8.50% crude ash. The moisture content of samples were significantly(p<0.05) lower than that of dasiks with Ulmus davidiana powder. The pH values were significantly decreased with increased Ulmus davidiana powder(p<0.05). The lightness(L-value) was significantly decreased as Ulmus davidiana powder increased(p<0.05). Redness(a-value) of dasik with Ulmus davidiana powder was significantly higher than that of the control group. However redness was decreased with the amount of increased Ulmus davidiana powder. The yellowness(b-value) decreased significantly as Ulmus davidiana powder increased(p<0.05). In the mechanical evaluation, hardness in the groups with Ulmus davidiana powder increased significantly(p<0.05). Adhesiveness of the control group was lower than that of the groups with Ulmus davidiana powder. Springness in the control group was lower than that in the groups with Ulmus davidiana powder. But no significant difference in cohesiveness, gumminess and chewiness among groups was found. The intensity of color, odor and astringency of dasik with Ulmus davidiana powder significantly increased as the amount of supplementation increased(p<0.05). And the preference of flavor with 12% Ulmus davidiana powder was significantly lower than that of the control group. In conclusion, rice dasik with less than 9% of Ulmus davidiana powder would be most proper in taste and overall acceptability.

  • DPPH radical scavenging activities were 66.80% by hot water extract and 41.86% by 80% methanol extract. Inhibitions of angiotensin I-converting enzyme (ACE) were 91.09% by hot water extract and 75.20% by 80% methanol extract. In this study, Sulgidduk samples were prepared with 1, 3, 5, and 7% concentrated sweet pumpkin powder (CSPP), and a control were examined for quality characteristics such as moisture content, water activity, color, textural characteristics, and sensory qualities, in order to determine the optimal ratio of CSPP in the formulation. The samples containing CSPP exhibited significantly higher moisture content than the control group. Water activity was not significantly different among the Sulgidduk samples. For the color, the control group presented significantly higher lightness as compared to the samples containing CSPP. The samples containing 1 and 3% CSPP had significantly higher greenness than the samples containing 5 and 7% CSPP. Yellowness increased as the level of CSPP content increased. In terms of textural characteristics, hardness, gumminess, and chewiness were highest at the 1% substitution level, while lowest at the 3% level. The CSPP samples presented significantly higher adhesiveness, springiness, and cohesiveness than the control group. In the consumer acceptance and characteristic intensity rating test, the control group showed significantly higher color and flavor as compared to the CSPP samples. Pumpkin flavor, delicious taste, and off-flavor increased with increasing amounts of CSPP. Softness, overall acceptability, and gumminess were not significantly different among the various samples tested. Sweetness was highest at the 5% substitution level, while lowest at the 1% level. In conclusion, the results indicate that substituting $3{\sim}5%$ CSPP to Sulgidduk is optimal, providing good DPPH radical scavenging activity and inhibition of ACE as well as reasonably high overall acceptability.

  • This study was carried out to investigate the physico-chemical and storage characteristics of sausages added mugwort powder at $4^{\circ}C$ during 13 days. The composition of fresh sausages was as the following : meat 60 % (w/w), lard 20 %, ice 20 %, salt 1.5 %, sugar 0.5 %, phosphate 0.25 %, mugwort 2 % or 5 %. Sausages were divided into three groups; control group mugwort 0 %, Treatment I mugwort 2 % and Treatment II mugwort 5 %. The pH, TBA(thiobarbituric aid) value, VBN(volatile basic nitrogen), rheology, and sensory evaluation were measured. The changes of pH of all groups were slightly decreased with increasing storage days. But, the significant difference of pH changes were not shown between mugwort 2 % (Treatment I) and mugwort 5 % (Treatment II) groups. The changes of TBA values of all treatments increased during storage periods. TBA values of Treatment I and Treatment II groups were significantly (p<0.05) higher than that of the control group. The change of VBN showed trends to increase during storage periods. The change of VBN of Treatment I was significantly (p<0.05) lower than those of the control and Treatment II. Hardness and brittleness of 2 % and mugwort 5 % groups were significantly (p<0.05) higher than that of the control group. Elasticity and cohesiveness of 2 % and Treatment II were significantly (p<0.05) lower than that of the control group. Also, Treatment I was superior to the other groups by the results of sensory evaluation. Therefore, these results suggest that it may be possible to manufacture sausages added 2 % mugwort powder which can help to increase storage periods, and improve quality of sausage.

  • To find the optimum proportion of Hydrangea serrata Seringe(HSS) powder, rice cakes were prepared with different quantities of Hydrangea serrata Seringe powder instead of sugar. Technical and sensory examinations were then conducted. The proximate components of the HSS leaves were 3.48% crude protein, 6.45% crude lipid, 7.98% crude fiber and 9.32% crude ash. The pH values of samples which replaced 25%, 50%, 75% and 100% of sugar with the HSS powder were significantly decreased(p<0.05). The groups with HSS powder showed a lower L value(lightness) and a value(redness) than that of the control group. The B value(yellowness) of the Sulgidduk containing the HSS powder was higher than that of the control group. The hardness of HS2 and HS3 was increased by the addition of the HSS powder. The adhesiveness of Sulgidduk groups with the HSS powder was higher than that of the control group. Springiness was not changed by adding the HSS powder. The cohesiveness of the Sulgidduk was significantly reduced by adding the HSS powder(p<0.001). The groups with no sugar showed the highest gumminess and chewiness. The added HSS powder caused both a darker color and a stronger odor, but the sweetness of the Sulgidduk which replaced the sugar with the HSS powder was decreased compared to the control group. The moisture content and the hardness was not affected by the addition of the HSS powder. The preference of color and taste was not changed by adding the HSS powder. The preference of flavor of the Sulgidduk with the HSS powder showed higher than that of the control. Overall acceptability of the Sulgidduk did not show any significant differences. As a result, Sulgidduk can be replaced 25% and 50% of sugar with the Hydrangea serrata Seringe powder.

  • The environment of the modern library is changing rapidly with advancements in information technology, massive increse in information, and with the changing needs of users for information in order to keep up with developments in science and technology. The library should also be in a constant state of change in accordance with the changing environment. But the current situation is that library organizations in Korea do not show any change. Here arises the need to diagnose the health of these organization. Organizational innovations can be achieved either by change in the organizational structure or administrative methods or in personal attitudes. In making organizational innovations, however, it is not sufficient only to change the organizational structure or the administrative methods without changing personal attitudes. The purpose of this thesis is to diagnose the health of university library organizations in Korea and to suggest prescriptions based on the results of this diagnosis, by means of organization development theory. In this study, the action research model and the diagnostic model were developed for the health of university library organization in Korea. The action research model consisted of 3 steps: diagnosis, intervention and evaluation. The diagnostic model comprised diagnostic criterion and diagnostic indicators. The health of an organization was selected as the diagnostic criterion. Diagnostic indicators were divided into 3 levels: personal job-satisfaction at the individual level, cohesiveness at the group level, and the organizational climate at the organizational level. Both the interview and the questionaire were used as diagnostic methods. The questionaire form was designed according to the Likert typle 5-point scale. For the investigation, 10 university libraries were selected from the private universities in Seoul, and questionaire sheets were sent to their 156 librarians and responses were received from 116 persons. An interview was carried out with a selected chief of departments of the library concerned. The results of the diagnosis show that the average personal job­satisfaction was 3.57, the group cohesiveness was 3.15 and organizational climate was 2.93, and accordingly the comprehensive health indicator was 3.22. The health of university library organizations in Korea was generally on the decline at all 3 levels. In particular, the organizational climate was in a very weak state. Most problems concern dissatisfaction with personnel policy, communications and non-professionally qualified directors. As the prescriptions, the following was suggested: institutionalization of the staff meeting for resolving problems with communication, appointement of professional directors, performance appraisal, conferring faculty status for librarians, and a suggest system. And for the improvement of the organizational climate, managerial grid training was suggested as one of the educational strategies for organizational development.
