In this study, a Yanggaeng with added loquat fruits puree was developed and studied on quality characteristics. The mixed ratio were 0%, 20%, 40%, 60%, 80%, 100% of loquat fruits puree. Loquat fruits puree have 83.49% of water, 0.36% of crude protein, 0.04% of crude fat, 0.46% of crude ash, $14.3^{\circ}Brix$ of sweetness, 75.10(mg/kg) of polyphenol and 4.01 of pH. The water contents of Yanggaeng were 41.78~53.37%, and showed significant increase (p<0.001). The sugar contents of Yanggaeng were increased from $28.7^{\circ}Brix$ at control group to $36.0^{\circ}Brix$ at 100% mixing group (p<0.001), while pH were decreased from 6.4 at control group to 4.26 to 6.4 at 100% mixing group. In color, the brightness (L-value) gradually decreased from 72.69 at control group to 43.64 at 100% mixing group (p<0.001), the redness (a-value) of control group was the lowest by -1.72 while 100% mixing group was the highest by 8.64 (p<0.001). The yellowness (b-value) of control group was 15.91 while that of 100% mixing group was 21.98 (p<0.001). The DPPH radical scavenging activity of control group was the lowest by 9.24% while that of the group 100% mixing was the highest by 46.17%. Total polyphenol was not detected from control group and 20% mixing groups, and 100% mixing group was The highest by 16.69 mg/100 g (p<0.001). Preference test showed the groups with mixing loquat fruits puree 60% or more were preferred (p<0.001) in color. There were no significant difference from sweet taste but sour taste of 100% mixing group was The highest by 4.85 (p<0.01). For texture and overall preference the most preferred groups were the groups of mixing of 60% and 80% of loquat fruits puree.
Researches on mineral nutrition, physiology and phyrsiological diseases, . cultivaction methods. brceding. pest control quality management and extension during 1976-1995 in Korea were reviewed Review in brceding and pest control was restricted to the researches directely related to cultivaction. Mineral nulrient up take. partion and varicos factors such as top dreasing. Light intersity etc. and interrelationship between minerals were investigated. Top dressing was not effective due to low minera1 requorement Physiological characteristics on tempelature light and water were well elucidated and applied to assess traditional cultivation method and its inovation. Photosyrnthetic pigments. light harvest proteins and activity of related enzymes were studied. In nitrogen metabolism arginine, praline, ammonium, threonine appeared to have important role in re growth of shoot Saponin metabolism was studied in relation to growth and new ginsenosides were found but physiological role of saponin was not clearly elucidated yet Endogenous growth regulators were reported and various erogenous growth regulators were studied for growth stimulation. short stem and seed pruning etc. Various physiological diseases were investigated for cause and control measures were established. Water culture was little studied Forest culture was studied but not retched the recommendable stage Drip irrigation straw mulching. seasonal shading and soil preparation method including soil fertility adjustment were established for practical application. Shading materials completely changed to polyethylene net and materials of polymers The research on ginseng cultivation in paddy field opened the way to establish the permanent ginseng cultivation plantation Ginseng harvester and seeder were developed in the late 1950s. Transplanted and many other machines were developed in the early 1990s. In ginseng breeding only pure line selection was of practical significance several verities were at the stage of seed propagation at ginseng plantations. Mutation breeding (${\gamma}$-ray. X-ray chemicals) was not successful. The research on plantlet formation through tissue culture was a little progressed but still far behind to vegetative propagation. Disease control research was concentrated in the isolation and identification of pathogans. their ecological charactelistics and biological control and soil humigation. Potato root rot nematodes was found and control method was established. Insect and small animal control research was greatly progresses in identification, ecological investigation, and ecological and physical control. Weed control was less important due to the development of mulching method of ridge and ditch. Quality factors of raw ginseng in relation to red ginseng process were extensively studied. Traditional quality measures were elucidated in accordance with modern analytical chemistry resulting in the importance of peptides in the centrat part rather than ginsenosides For large root production growth promoting rootzone micrcorganisms (PGPRM) were isolated and active compounds were identified. Field test on PGPRM was on going. Varictus methods formality improvement through cultivation were developed. Management research of ginseng production was rare Extension was active throuch official and private organizations and through workshop for the extension specialists, and direct lectures to grower's. Extension services made the researcher to understand the existing problems at grower's fields. Research environment for ginseng production was in prime time only for three years when Korea Ginseng Research Institute was established then gradually aggravated.
This study evaluated the quality characteristics of mungbean starch gel prepared with different amounts of Salicornia herbacea L. powder. In order to determine the optimal addition level of Salicornia herbacea L. powder, samples of mungbean starch with 0, 2, 4, 6 and 8% of Salicornia herbacea L. powder substitute were prepared, after which physicochemical, textural and sensory quality characteristics were measured. Upon increasing Salicornia herbacea L. powder levels in the formulation, moisture contents of samples decreased, except the 6% addition sample, and salinity levels increased. Total phenolic contents and DPPH radical scavenging activities also increased significantly upon addtion of Salicornia herbacea L. powder. According to the texture analysis, hardness and gumminess decreased with increasing amounts of added Salicornia herbacea L. powder. From the sensory tests, 4% Salicornia herbacea L. powder sample received the highest overall acceptability score with proper levels of flavor, saltiness and texture. As a result, to increase usage of Salicornia herbacea L., the optimal formulation consisted of 4% Salicornia herbacea L. powder substitute for mungbean starch.
In fostering dynamic, innovative SMEs, hidden champion companies can be an appropriate model for SMEs to learn the success factors. On the other hand, the need for intellectual property management is becoming important as the value of a company is changing from a financial asset to an intellectual property. Therefore, in this study, the patent portfolio analysis of the hidden champion companies mentioned in Herman Simmon's book "Hidden Champion" was performed. As a result of the analysis, it was confirmed that patents are not possessed or patent activities are actively carried out and a differentiated intellectual property management strategy is implemented to improve patent quality depending on the characteristics of the technology possessed. The results of these studies can be used as basic data to prepare an intellectual property management strategy for companies that want to create opportunities to acquire monopoly rights and reduce patent maintenance and management costs. In addition, in this study, the patent IPC analysis verified that Herman Simmon's claim that "Hidden champions have the ability to focus on core competencies and focus on one technology" is valid.
This study was carried out to review the guidelines being used by law and national policy concerned on river environments management and suggest the applicability of newly developed river environment assessment system. In the current legal system, the national river environment management system is insufficient in securing an independent status in the legal institutional system which is separated to the Ministry of Land, Transport and Infrastructure and the Ministry of Environment. And the river environment assessment system of the national standard, which is a core matter, has not been established yet. In particular, there is a lack of integrated approach between the upper and lower plan or related plans on water resources, water quality, river environment and aquatic ecosystem management. In addition, the consistency and effectiveness as the process of planning and design according to the current status and comprehensive analysis and evaluation of the river environment were not secured either. To integrate national river environment management system and improve efficiency, I proposed the establishment of hierarchy and connection between national river plans, and the adoption and application of developed assessment system based on characteristics of river environment in Korea. Finally, I proposed the separated application with dividing the developed assessment system including the naturalness of river environment and suitability of water friendly activity into both assessment method for management plan of water resources of river basins & basic river plan respectively.
The trends of green growth and eco-friendliness came to be the core development indicator for the sustainable global environment. Korean government reflected these trends in the main flows of the national development index, and suggested diverse directions for green construction technologies and high quality construction environment through Third master plan for construction environment. However, the efforts to follow these trends during the construction process as a step for production phrase are not being considered enough yet. In this study, we identified the basic environmental management factors in order to enhance the eco-friendliness of public housing construction sites, and suggested the reasonable conducting parties and process for those respective factors. The results of this study are expected to be the valuable reference in defining the required activities and participants' responsibilities, and improving the work process for systematic on-site environmental management. In applying those results, the discussion should be followed on the executing party of each unit activity and the responsibility assignment for each process. At the same time, the legislation and standard related to environment need to be essentially amended. In the future, the method of evaluating the environmental management activities, and the technical solution to environmental problems are to be reviewed as a further research for successful environmental management.

Consumer needs becomes various in a mature mobile telecommunication market, while service differentiation is hard to achieve. Because of the introduction of number portability, switching barrier becomes lower and the competition among telecommunication service providers is getting fierce in order to maintain and obtain customers. Moreover, HSDPA, which is a new telecommunication service, caused the intense marketing activity for the move to the next generation customers. Under these circumstances, brand equity can be a key to a long-term competitive edge for mobile phone service providers. However, there were few researches reporting the mobile telecommunication brand equity, and none of them analyzed if customer equity which particularly is developed at the CDMA market has an effect on HSDPA service. In this study, we identified the determinants of mobile telecommunication brand equity, which is focused on brand image, customer benefit, price, service quality, and marketing activity, and its influence on the HSDPA service subscription behavior. Finally, we suggested the strategic implication of brand management strategies for mobile phone service providers.
During the middle age of a woman's life cycle. several health changes and problems occur. Therefore. middle aged women must manage their health and maintain quality life by coping with bodily changes. However. today there is not enough research and health programs for middle aged women. Data from the study will be used for health promotion program development of middle aged women. Data was collected from January 21 to 24. 1995 by telephone interview. Four hundred middle aged women between 40 and 59 years old and living in Chon Ju City were interviewed. The results of this study were as follow: 1. Frequency rate of menopausal symptoms was 38.4%. The most serious menopausal symptom was psychosomatic symptom. Mean score orders of experienced symptoms were back pain, joint pain(1.80). nervousness(1.80). general weakness(1.67). 2. The most important problems as perceived by the clients were children(45.8%), health (24.0%) and economics(7.8%). The most serious health problems were concerning the muscle-skeletal system(45%) such as arthritis. spinal disk problems and osteoporosis. Adult diseases04.S%) such .as hypertension and diabetes were also health concerns. Health management activities reported were exercise(22.5%), social activity02%) and inactivity(53%)' 33% of clients were interested in health groups and they wanted a program of health education, exercise and social activity to be provided. 3. General characteristic variables were significantly related to the level of menopausal symptoms as follows: age(t=-2.06, p=0.040), status of marriage(t=-3.56, p=0.000), educational level (F=4.35. p=0.05) and menopausal status(t=4.37, p=0.000).

The purpose of this study was to investigate the effect of a pillow simulated with cranial sacral therapy (CST) on sleep induction using electroencephalography (EEG). This study included 12 voluntary participants divided into experimental group (CST group) and control group (Non-CST group) to observe EEG changes. The position of the electrode for EEG measurement consists of 8 channels electrodes (Fp1, Fp2, F3, F4, T3, T4, P3 and P4). In this study, we measured the fall asleep time, change of brain activity and sleep wave ratio using EEG wave (${\delta}$, ${\theta}$, ${\alpha}$, ${\beta}$ and ${\gamma}$). As a result, the mean fall asleep time of the experimental group was shorter than that of the control group significantly (p < 0.001). Also in comparison with the control group, both the delta (d) and theta (q) wave corresponding to the slow waves showed a larger increase and the alpha (a) wave showed a larger decrease significantly. The slow waves of experimental group showed a higher rate of significant increase than the control group (p < 0.001). Therefore this study showed that pillow based on CST had an effective in improving sleep induction and quality.
The cyclic alternating pattern (CAP) is a periodic EEG activity in NREM sleep, characterized by sequences of transient electrocortical events that are distinct from background EEG activities. A CAP cycle consists of two periodic EEG features, phase A and subsequent phase B whose durations are 2-60 s. At least two consecutive CAP cycles are required to define a CAP sequence. The CAP phase A is a phasic EEG event, such as delta bursts, vertex sharp transients, K-complex sequences, polyphasic bursts, K-alpha, intermittent alpha, and arousals. Phase B is repetitive periods of background EEG activity. The absence of CAP more than 60 seconds or an isolated phase A is classified as non-CAP. Phase A activities can be classified into three subtypes (A1, A2, and A3), based on the amounts of high-voltage slow waves (EEG synchrony) and low-amplitude fast rhythms (EEG desynchrony). CAP rate, the percentage of CAP durations in NREM sleep is considered to be a physiologic marker of the NREM sleep instability. In insomnia, the frequent discrepancy between self-reports and polysomnographic findings could be attributed to subtle abnormalities in the sleep tracing, which are overlooked by the conventional scoring methods. The conventional scoring scheme has superiority in analysis of macrostructure of sleep but shows limited power in finding arousals and transient EEG events that are major component of microstructure of sleep. But, it has recently been found that a significant correlation exists between CAP rate and the subjective estimates of the sleep quality in insomniacs and sleep-improving treatments often reduce the amount of CAP. Thus, the extension of conventional sleep measures with the new CAP variables, which appear to be the more sensitive to sleep disturbance, may improve our knowledge on the diagnosis and management of insomnia.
