This study was carried out to investigate the effects of tangerine (Citrus unshiu) peel on the physicochemical properties and sensory score of pork patties. Four types of pork patties were evaluated: T0 without tangerine peel, T1 with 0.3% tangerine peel, T2 with 0.7% tangerine peel, and T3 with 1.0% tangerine peel. The pH level changed based on the storage period. The pH levels of T2 and T3 were lower than those of T0 and T1 during storage. The L-value (lightness) of samples did not significantly change, and showed no significant difference during storage. The a-value (redness) decreased during storage, and that of T0 was lowest among the samples. The b-values of samples did not significantly change, whereas that of pork patties with tangerine peel was higher than that of pork patty without tangerine peel. The TBARS increased with a longer storage period, and the values for T0, T1, T2 and T3 were 0.82, 0.32, 0.26 and 0.26 mg/kg, respectively, after 10 days of storage. DPPH radical scavenging activity decreased with a longer storage period, and those of T2 and T3 were significantly higher than those of T0 and T1. The VBN contents of T0 and T1 increased with a longer storage period, and that of T0 was highest among the samples. Water holding capacity decreased, and cooking loss increased, whereas those of samples did not significantly change during storage. Hardness and chewiness increased while springiness and cohesiveness decreased during storage. The results of this study show that tangerine peel is a natural antioxidant, due to its antioxidative activity and does not affect physical characteristics. Therefore, addition of 0.7% tangerine peel may be suitable for manufacture of patties.

The effects of dippin treatments using Glycyrrhiza uralensis extract (0.5%, 1.0%, 2.0%) and calcium chloride (0.5%, 1.0%, 2.0%) on the quality of peeled chestnuts were investigated. Following dipping treatment, peeled chestnuts were vacuum-packed using a 75-㎛ polyethylene PE and nylon film, and stored in a 0 ℃ incubator for six weeks. The dipping treatments of the peeled chestnuts successfully achieved browning inhibition. The browning degree following 2.0% calcium chloride treatment was the lowest at 0.68 OD. The color change (ΔE) of the peeled chestnuts was the highest (6.0) in the control, and the lowest (3.5) for the 1.0% and 2.0% calcium chloride-treated samples. G. uralensis extract and calcium chloride treatments did not impact weight, moisture loss rate, firmness, or the soluble solid content of the peeled chestnuts following storage. The decay rate was 12.0% in the control group, and 11.0%, 11.5%, and 11.0% for G. uralensis treatment at 0.5%, 1.0%, and 2.0% calcium chloride treatment, respectively, and 13.0%, 9.5%, and 9.0% at 0.5%, 1.0%, and 2.0% calcium chloride treatment, respectively. Sensory evaluation (palatability, off-odor) showed that a 2.0% G. uralensis extract treatment presented excellent results during the storage period. Texture and color indicated no differences as a result of the browning inhibition treatments. Therefore, when considered comprehensively, a 2.0% G. uralensis extract treatment was shown to be effective for maintaining the quality and providing browning inhibition of peeled chestnuts. This result isexpected to solve the problem of quality deterioration in the form of sour taste, which is a problem in chemical processing.

As a serial study to investigate optimum storing temperature of fresh ginseng (Panax ginseng C. A. Meyer), the respiration rate and internal quality of the ginseng was compared during storage for 16 weeks at $-3^{\circ}C$, $-1.5^{\circ}C$ and $0^{\circ}C$. At initial storage period, respiration rate of fresh ginseng was lower at lower temperature, but thereafter it was negligible. Changes in the firmness of fresh ginseng were not significantly different by the storage temperature. The soluble solids content in fresh ginseng was rapidly increased in the early part of storage, and fresh ginseng stored at a lower temperature had a lower content of soluble solids. The iodine-stained color for starch of the main root was rapidly changed for 4 weeks, and L value of the color was the highest in the center, followed by the cambium and the cortex. pH were a little change depending upon the storage temperature, and as a whole, pH was the lowest at $-3^{\circ}C$, followed by $-1.5^{\circ}C$ and $0^{\circ}C$. Although the content of crude saponin tended to somewhat increased as the storage period passed, the effect of storage temperature on changes in the content was not clear. In the sensory evaluation of 'unique flavor' of fresh ginseng using 5 point scale, higher than 3 point was marked for 8 weeks at $-3^{\circ}C$, 14 weeks at $-1.5^{\circ}C$ and 16 weeks at $-0^{\circ}C$ during storage (p < 0.05).

To achieve the purpose of this study, the subjects of this study are 110 male or female gastro intestinal tract patients who are older than twenty, are hospitalized in Pusan University Hospital from 1995. 5. 28 to 1995. 9. 25 and have had medical treatment. The modified pain assessment of cancer patients of Cornne, H. Rosermary, M. was used as the tool of study with 16 questionaries. The pain score consists of sensory intensity score and distress score. The data was analyzed by the SPSS statistical program number, percentage, mean, standard deviation, t-test, One Way Anova and Duncan's Multiple Range Test were utilized for analysis. The results were summarized as follows : 1. In population-sociological characteristics : in the age-range of subject, the sixties are most as 32.7% and the subjects after the forties are 89.5%, in sex of subjects, male patients are 66.4% and female 33.6%, in the number of family, the subjects who has 4 or above families are 70% and the subjects who live with their spouse, sons and daughters are 54.5% 2. In the disease characteristics : stomach cancer patients were most as 39.1%. And the most of patient who had never been operated before. In time of pain, the most of subjects were intermittent. In the type of pain, the most of subjects were 'dully pain' as 31.8%. Metastatic subjects were 30.0%. In the origin of pain, nervous pressure was 50.8%. The number of complication was 46 and most of complication are obstruction as 6%. 3. In the pain level, 91subjects complained pain. And mean pain score was $287.1{\pm}116.1$ The mean pain score of female subjects was higher than that of male subjects. 4. In the pain characteristics, the pain began usually at meal time as 40.7%. The duration of pain was mostly from 1 month to 3 months as 57.1%. The appetite was mainly concerned with the pain as 31.8%. The etiology of pain was usually tumor as 69.3%. The meaning of pain was incurable disease as 14.5%, anxiety, death and suffering. 5. The 56(61%) of 91subjects were treated with Analgesic pain management. The kinds of Analgesic is usually valentac as 46.4%. The medication was usually intramuscle as 66.1% at whenever necessary, Response of Analgesic after Medication was usually 'moderate release'. The side effects of medication were nausea as 26.8%. The average amount of morphine dosage hospitalized to cancer patients with pain was 80mg in a day and metastatic cancer patients with pain was 101.9mg in a day. 6. In the relation between the disease characteristics and pain level, there is a significant statistical difference : whether subjects had been operated or not : (t=2.88, p=0.005), time of pain is(t=3.34, p=0.005), stage of metastatic(F=9.323, P=0.0002), and type of pain(F=4.013, p=0.0008).

Background: During movement the major inputs to nervous system come from firstly the muscle and joint to maintain posture and motion and secondly the chemoreceptors and baroreceptors to adjust the cardiovascular and respiratory function. Their complex relationships are generally studied for many years but the direct relation between the joint and respiratory system is not studied thoroughly until now. So this experiment was performed to determine whether the natural movement of knee joint can cause the enhancement of respiratory function by observation of the changes of respiratory rate, phrenic nerve activity and inspiratory neuron activity during the stimulation of knee joint in cat anesthetized with $\alpha$-chloralose. Method: Twenty six male adult cats were used and the extracelluar recording using bipolar platinum electrode and carbon filament electrode was done to record the changes in the activities of phrenic nerve and inspiratory neuron movement of knee joint, injection of chemicals into the joint cavity and electrical stimulation of articular nerve were done. Results: The 60 Hz. could not but 120 Hz. flexion-extension movement of knee joint increased respiratory rate(R.R.), tidal neural activity(TNA) and minute neural activity(MNA). Intra-articular injection of lactate could not increase R.R. but significantly increase TNA and MNA which represented the enhanced respiratory function. Injection of potassium chloride showed similar effects with the case of lactate but the duration of effect was shorter. The electrical stimulation of medial articular nerve with IV strength which could activate only group I and II afferents showed increased TNA and MNA during stimulation but 20 V stimulation which could activate all the afferents increased all the respiratory parameters. The changes of inspiratory neuron activity by knee joint stimulation was similar to that of phrenic nerve. Conclusion: The respiratory center could be directly stimulated by the activation of group I and II articular afferents and it seemed that the magnitude of the respiratory center enhancement is proportional to the amount of sensory information from the knee joint. These facts might suggest that the respiratory function could be enhanced even by the normal movement of knee joint.

We investigated the prolongation of freshness and quality during storage of muskmelons harvested at different times and treated with 1-MCP. The weight loss rate increased in all samples as the storage period was extended, although the weight loss of 1-MCP-treated samples was lower than that of controls, regardless of the degree of maturation. Additionally, the hardness of 1-MCP-treated samples was higher than that of controls, again independent of maturation stage. Specifically, 1-MCP treatment delayed softening of muskmelons, as 1-MCP- treated samples showed a high hardness value after 22 days of storage, whereas hardness of control samples decreased rapidly after 10 days. The soluble solid level in muskmelons harvested 92 days after planting was $14.3^{\circ}$ Brix, whereas that of fruit harvested after 90 days was $12.7^{\circ}$ Brix. There was no significant difference in the acidity of 1-MCP-treated samples and controls after 7 days of storage, although the acidity of 1-MCP-treated fruit was greater than that of controls after 13 days, regardless of the degree of maturation. The L-values (lightness) of 1-MCP treated samples were higher than those of controls for the first 10 days of storage, but the reverse was true after 13 days of storage. The b-values (yellowness) were high in control fruits during the initial period of storage, but greater in 1-MCP treated samples after 19 days of storage. The respiration rate of 1-MCP treated samples was lower than that of controls, regardless of the degree of maturation. Sensory evaluation revealed that the texture of control fruit decreased as storage time rose, whereas that of 1-MCP-treated samples did not fall until 28 or 34 days of storage (p<0.05). Overall acceptability based on a marketable score of 5 points showed that 1-MCP-treated muskmelons scored higher than controls, and remained fresher on storage.

This study was carried out to investigate the effectiveness of Leuconostoc mesenteroides isolated from octopus baechu kimchi as a potential starter for seafood kimchi. L. mesenteroides is lactic acid bacterium currently used as a starter for kimchi production. We selected the most effective L. mesenteroides strain from the 7 strains isolated from octopus baechu kimchi and, based on biochemical properties and 16S rRNA sequencing, identified the selected strain as L. mesenteroides SK-1. The SK-1 strain exhibited acid-tolerance, good survival capacity, and excellent dextran productivity. We investigated the effects the SK-1 of starter on seafood kimchi fermentation. Octopus baechu kimchi was fermented with L. mesenteroides SK-1 at $4^{\circ}C$ for 35 d. The decrease in pH and increase in acidity in octopus baechu kimchi fermented with the SK-1 starter occurred more quickly than that in the control kimchi indicating that. Octopus baechu kimchi with SK-1 starter has a relatively slow rate of increase in lactic acid production. As a result, octopus baechu kimchi prepared with L. mesenteroides SK-1 can be maintained at a suitable ripening degree over an extended period of time compared to that of the control kimchi, Moreover, the octopus baechu kimchi started with L. mesenteroides SK-1 has excellent sensory properties, including a refreshing taste, and a weak sour odor.
