  • This experiment was carried out to improve on the simple and conventional processing method by studying the characteristics of poultry meat. For the experiment, 20 hens culled and 20 broilers were slaughtered and divided into the following five groups; whole carcass, skinned carcass, debonned carcass, thigh muscle and breast muscle. Each group was ground by the super grinding machine. The results tobtained are summarized as follows; (1) The percentage of the ready-to-cook of cull hens and broilers was $64.32{\pm}2.11,\;67.96{\pm}1.16$, and of the water uptake, $105.43{\pm}1.9,\;104.13{\pm}0.2$, respectively. (2) In the chemical composition, broiler meat showed high moisture content and a little low fat content, as compared with cull hen meat. By groups, whole carcass ground meat contained lower maisture content, and higher fat and ash content than thigh muscle and breast muscle. (3) Thigh muscle and breast muscle group was higher than the other and whole carcass group was lower for the relative WHC and water retention.(4) The higher temperature the higher cooking loss percentage in all groups, and whole carcass group was the highest cooking loss percentage among the all groups.(5) The significant difference was little observed for the relative WHC, water retention and cooking loss percentage by groups between cull hen and Broiler.

  • This study was performed to get the basic information on nitric acid pulping of beech wood. In order to reduce the consumption of nitric acid, alkali pretreated woods were applied to a nitric acid pulping process. It consisted of nitric acid treatment to a high residual lignin content and the subsequent delignification with alkali, required far less chemical than the single stage method. At the first stage of nitric pulping, pulp yield descreased with increasing cooking time and 3 percent of nitric acid was more effective on the delignification of wood than 1 or 2 percent. Alkali pretreatment of wood improved significantly the rate of delignification, and 79 percent of the pretreated yield was good enough for excellent delignification. The dissolution of carbohydrate (mainly xylose) was increased with increasing cooking time, especially at the second stage. It would be considered that carbonyl groups introduced to polysaccharides in wood by nitric acid oxidation caused the degradation of carbohydrates.

  • Maillard reaction products (MRPs) were produced from aqueous solution of various sugars with defatted hydrolyzed soybean protein (DFHSP) with different temperatures and pressures. Physicochemical properties of MRPs were investigated; also, DPPH and hydroxyl radical scavenging activity and sensory properties were evaluated. MRPs from ribose and DFHSP had the highest reactivity with larger pH reduce, higher browning index increase and higher antioxidant activity than other MRPs from other sugars. The antioxidant activities were increased with increasing temperatures and pressures of reaction. The highest antioxidant activity and sensory preference were obtained from MRPs with ribose at $140^{\circ}C$ with 2.8 kg/$cm^2$ for 30 mins.

  • There are three types of benefits in the National Health Insurance Act of Korea. Those are the treatment benefit, statutory uninsured medical benefits and arbitrary uninsured medical benefits. Recently the Korea Supreme Court changed its past legal theory and permitted the arbitrary uninsured medical benefits under the strictly exceptional conditions. According to the Supreme Court's decision, the existence of procedural difficulty, the medical necessity and the patient's consent are necessarily required in order to allow the legal exceptions in arbitrary uninsured medical benefits. Among the three requirements, the doctor's explanation and the patient's fully informed consent are the most important essentials in this legal conflict. The requirement concerning the doctor's explanation and the patient's consent roles like a hole in the ice as a breathing hole in the arbitrary uninsured medical benefits. The most cases dismissed after Supreme Court Decision 2010DU27639, 27646 Decided June 18, 2012. were due to the defect of three requirements.

  • The war simulation systems in Republic of Korea Army have been getting more and more important because soldiers can effectively and efficiently learn and share their war-related knowledge based on the interactions through the systems. But, up to now, the access to the war simulation systems has been limited to only soldiers. So, little research on them has been conducted. This study explores the effects of the antecedents to the flow experience and the characteristics of the systems on soldiers' intentions to use them. Based on the 118 samples collected from officers in Republic of Korea Army, this study empirically shows the logical reality of the war simulation systems and the flow experience positively influence soldiers' intentions to use the systems and the clarified goals, feedbacks, and the levels of the missions in the systems are significant antecedents to the flow experience. Useful implications are presented and discussed based on the new findings.

  • In spite of the world-wide increase of incidence of pesticide poisoning due to greater use of pesticides, the epidemiological study of pesticide poisoning in Korea has been grossly neglected. The author gained access to the medical records for two year period (1981 through 1982) from local clinics, hospitals and health centers of Kyungpook area to investigate the status of the pesticide poisoning. During these two years, there were 1,618 cases of documented pesticide poisoning, of which in 1981 were 765 and in 1982 were 853. Those in the twenties decade of age was the most frequent and the male(70%) was more liable than the female (30%). In view of manner of poisoning, occupational poisoning was 27.8%, accidental 5.6%, and suicidal 66.6%. There are three distinct groups which make up the large majority of both fatal and nonfatal cases; young children who accidentally ingest pesticides, young to middle age adult who are occupationally poisoned, and middle age to older adults who suicidally ingest pesticides. The seasonal distribution of these poisonings disclosed the peak month to be July, with August next, followed by June and September. Only 11% of cases occurred during the three-month winter season of December to February. Thus pesticide caused poison- ing was primarily a summer and early fall occurrence. During these two years, average of 67 cases of poisoning was observed monthly. Of the pesticide poisoning documented, 49% were treated with poisoning patients from local clinic and 43% from hospital. The case fatality rate of occupational poisoning was 0.9%, accidental 5.6% and suicidal 20.3%. The mean overall case fatality rate was 14.1%. Annual incidence of pesticide poisoning was 25.4 per 100,000 population in the study area. There is a nationwide need for more reliable date on pesticide poisoning. This need can only grow more acute with the passage of time because of the increasing importance of pesticides as a cause of morbidity and mortality.

  • In this paper, we design and implement location information system and user mapping system using DSDV(Destination Sequenced Distance Vector) routing algorithm in ad-hoc network environment to efficient manage a number of mobile devices. The software part in proposed system construct ad-hoc network using DSDV routing algorithm and it activate alarm system, such as vibration, when one of devices disappears in the network. The hardware system, called u_LIN (User Location Information Node) construct ad-hoc network and it helps to find a disappeared device by using warning system. When we evaluate the performance of our prototype system, we have checked a correct operation, within the range of 250m in case of 1:1 communication and within the range of 100m in case of 1:N communication. The implemented system in this paper is highly expected to flexibly use in juvenile protection system, stray-child protection system, tourist guide system and so on.

  • The effect of heat or chemotherapeutant treatment on the mosaic virus infected garlic(Allium sativum L.) scales and that of chemotherapeutant added to the culture medium were summarized as following. The treatment of the virus infected garlic scales at $37\~57^{\circ}C$ for 35 days to one hour in water or in air shelved no effort of inactivating the virus. Although treatment of the garlic scales at $62\~72^{\circ}C$ for 90 to five minutes reduced the mosaic symptom on the leaves of the garlic plants grown after the heat treatment, it reduced the growth vigor of the plants so greatly that complete inactivation of the virus in garlics was not feasible. The mosaic symptom on the leaves of garlic plant was reduced when the infected garlic scales were grown after 24 hours soaking in $10\~50\;ppm$ Malachite Green, 2,4-Dichlorophnoxy Acetic Acid, or in $20\~100\;ppm$ Quinhydron. These chemotherapeutants, however, inhibited the growth of garlic plant at the high concentration. Garlic scales soaked in $10\~50\;ppm$ Naphthyl Acetic Acid showed the least mosaic symptom without its complete extiction on the garlic leaves. When incorporated into the modified Murashige-Skoog's medium, $0.5\~l.5\;ppm$ Naphthyl Acetic Acid could inactivate the mosaic virus in newy developed garlic plants showing no mosaic symptom on the leaves, no inclusion bodies and intact nuclei in the leaf tissue cells.

  • This study investigated heat generation characteristics of knitted and woven intelligent garments made of ZrC imbedded yarns through thermal manikin measurement. These emotional and intelligent thermal characteristics by thermal manikin measurement were analysed and compared with light/thermal radiation experimental results. Surface temperature of ZrC imbedded woven and knitted fabrics by light/thermal radiation measurement was $4^{\circ}C$ and $2^{\circ}C$ higher than that of regular PET control fabrics, respectively. Clo value as heat generation characteristics of ZrC imbedded woven and knitted garments with light exposure was 0.14 and 0.08 higher than that of regular PET control garments, respectively. These results were attributed to the far-infrared thermal radiation from ZrC imbedded in the core part of the intelligent bi-component filament, which was verified by far-infrared emissive power ranged between $6{\mu}m$ and $20{\mu}m$ through FT-IR experiment and by inclusion of Zr through EDS ingredient analysis. However, compressibility of ZrC imbedded woven fabric was lower than that of regular PET one, and bending rigidity was higher than that of regular one, which resulted in a little stiff tactile hand property of ZrC imbedded fabric. We found that ZrC imbedded intelligent woven and knitted fabrics were applicable to the intelligent garment as a heat generation textile material by thermal manikin measurement.
