Chloral hydrate is one of the most widely used sedative agents to control the difficult-to-treat young age group in the dental clinic. We are often frustrated to see the patient still awake and cry with agitation even after far more than the normal onset time of Chloral hydrate. In such a case, the patient has to be rescheduled for another sedation visit with different agents and/or routes which greatly disappoints the guardians. This study was designed to test the efficacy of one sedative regimen that can possibly help the clinician complete scheduled treatment without postponement. We have tried sleep induction with mixed gas of Enflurane(2vol%) and $N_2O(50%)-O_2(50%)$ for $60\sim120$ seconds to 35 patients of those who failed to respond properly to the dose(70mg/kg)of oral Chloral hydrate. The Result of this regimen was compare to those of two oral regimen of Chloral hydrate/Hydroxyzine and Chloral hydrate only Analyses of result on vital signs and behavior pattern were performed. The outcome of the study suggest that sleep induction by a short inhalation of low dose of $Enflurane/N_2O-O_2$ provide dentist with suitable condition for the completion of scheduled treatment in the patient who failed to oral Chloral hydrate. Evidence of adverse effect was not detected or reported during and/or after the procedures.

This research was to examine the effects of downsizing kitchen employees in a hotel on their job efficiency and to verify differences in the individuals' behavior characteristics according to DISC behavior types in this causal relationship. Through SPSS 17.0 program, factor analysis, reliability analysis, correlation analysis, and multiple regression analysis were conducted on 200 samples secured for an empirical research. Two factors for the downsizing items and two factors for the items related to job attitude were extracted. Hypothesis 1 was that the downsizing within a hotel has significant negative (-) effects on job attitude. As a result of the verification, it was found that downsizing had significantly negative effects on the job attitude of cooking employees as factors for organizational commitment in employment circumstances (${\beta}$=-.256), and employment anxiety (${\beta}$=-.258), and as factors for job satisfaction in employment circumstances (${\beta}$=-.319), and employment anxiety (${\beta}$=-.174). Hypothesis 2 was that the downsizing according to DISC behavior types has significant negative (-) effects on job attitude. As a result of the verification, it was found that in the organizational commitment factors, the dominance type (D) was more influenced by employment anxiety (${\beta}$=-.435) than by any other types, and the conscientiousness type (C) was not influenced by organizational commitment. In the job satisfaction factors, the steadiness type (S) was more influenced by the changes in employment circumstances (${\beta}$=-.414) than by other types, and the dominance type (D) was not influenced. Based on the results of this research, it can be said that hotel's downsizing strategies influence job attitude such as organizational commitment and job satisfaction of cooking employees, and that there are differences in the influences according to the individuals' behavior types of kitchen employees.

An arboretum is defined as a collection of facilities that conserve plant species by surveying, collecting, and proliferating and preserving the plants in nature, perform diverse researches on plants and display the plants in exhibition spaces or outdoors as well as provide the public with educational programs and refreshment spaces according to the laws concerned. The public, however, recognizes the exhibition and education functions on plants of arboretum more importantly compared with the roles to survey, collect, and proliferate plants as regulated by the laws. In particular, arboretum plays a role to offer a pivotal educational place in urban area where the public can obtain an hands-on experience and understanding on a wide range of plant species and natural environment. The study aims to estimate the non market environmental values of Daegu Arboretum operated by Daegu Metropolitan City government by using the Contingent Valuation Methods (CVM), which yields the current monetary estimates for the arboretum. The value estimation was undertaken by using the Double-Bound Dichotomous Choice (DBDC) method, and each estimated value was derived from respective functions based on a logit distribution known to include relatively stable estimates according to the shape of the distribution. Considering the statistical fitness test results, the author estimated the amounts of the Willingness To Pay (WTP) such as mean WTP of 12,718 KRW, median WTP of 11,033 KRW, and truncated mean WTP of 11,468 KRW, which represented the annual recreational values per a person visiting Daegu Arboretum respectively. The analysis showed that Daegu Arboretum created the annual environmental values which were estimated to be approximately 16 to 19 billion KRW. The study also has an implication that the valuation method for the environment of Daegu Arboretum may be effectively applied for estimating the values of other types of environmental goods by altering the locations or goods to be analyzed.

Objective：This study is designed to get clinical guidelines for management of children with TBI by examining neuropsychiatric sequelae of TBI, determining whether the severity of TBI, type of treatment, and enviornmental factors are related to those sequelae, and defining the adequacy of public psychological tests as evaluating tools for them. Method：This is chart review of 47 children, aged 5 to 14 years, referred to a psychiatric outpatient clinic for neuropsychiatric evaluation at least 6 months after TBI. Data on the initial GCS score, associated injury, treatment type, and duration of hospital stay are obtained from medical records. EEG, MRI, intelligent test, and several psychological tests are administrated at the point of assessment. Results：1) Cognitive symptoms outnumber externalizing behavioral, emotional, and somatic symptoms, with no significant differences of frequencies of those 4 categorical symptoms between mild injury group and moderate to severe group. 2) Children treated with non-surgical method(p<0.01) complain more cognitive symptoms than the others. 3) Behavioral symptoms are related to younger age(p<0.05), and to anticonvulsant medication(p<0.05). 4) Children with associated injury complain emotional symptoms more frequently(p<0.05). 5) More somatic symptoms are presented by children with no medication(p<0.05), and with higher I.Q(p<0.05). 6) Low I.Q is correlated to low GCS score (p<0.05). Cognitive impairment is confirmed in 25 in 42 children complaining cognitive symptoms though I.Q test and BGT, whose hospital stay is longer than the others(p<0.05). 7) emotional disturbance is confirmed in 22 in 25 children showing emotional problems through psychological tests, who complain cognitive symptoms more frequently(p<0.05). Conclusion：This findings suggest that even mild TBI children need to be followed-up and treated as complaining neuropsychiatric symptoms over 6 months after injury, and shorter hospital stay is recommended for cognitive and emotional status of children, and for better evaluation of neuropsychiatric sequelae of TBI, more specific tests should be included in neuropsychological test tools.

Rice quality should be considered as a primary consumer requirement. Regarding marketing, characteristics such as appearance, physicochemical properties, and palatability of brand rice are of high economic importance. Therefore, this study was conducted to select the optimal rice cultivars representing the commercial rice brands of Gyeongsangbuk-do province in Korea. Various rice grain quality components, grain appearance, several physicochemical properties of rice grain, and texture or palatability of cooked rice grains of ten cultivars (namely 'top quality rice') cultivated at three different locations, such as inland mountainous and southern plain areas of Gyeongsangbuk-do province in 2013~2014, were evaluated, and the obtained data was analyzed. 'Hiami' showed slightly higher protein contents and lower palatability of cooked rice than the other rice cultivars. Rice production and head rice yield produced at Gumi were the highest. The protein content of milled rice produced at Andong, an inland mountainous region, was approximately 0.3% point lower than that from other locations, whereas the amylose content of milled rice was approximately 1% point higher than those from the other plain regions, Daegu and Gumi. We evaluated the texture, Glossiness value determined using a Toyo teste meter and palatability of cooked rice of ten cultivars. The hardness of cooked rice produced in Andong was slightly lower than that produced in Daegu and Gumi, and additionally, the palatability of cooked rice produced in Andong was the best, followed by that producted in Gumi and Daegu. Considering rice yield and grain quality in the major rice cultivation areas of Gyeongsangbuk-do province, the rice cultivars that may be suitable for each region could be recommended mid-late maturation: 'Younghojinmi' and 'Mipum' in Daegu, 'Daebo', 'Samgwang', Chilbo' and 'Younghojinmi' in Gumi, 'Samgwang', 'Jinsumi' and 'Sukwang' in Andong. These results obtained in this study imply that the selected cultivars with high yield and quality could be recommended with high priority to rice farmers in the regions.

The 「Act on Remedies for Injuries from Medical Malpractice and Mediation of Medical Disputes」(hereinafter referred to as 'the Act on Mediation of Medical Disputes') provides that the state should compensate the victims of medical accidents occurred irresistibly in childbirth despite that health and medical service personnel fulfilled their duty of care for their damage within the range of its budget(Article 46 of the Act on Mediation of Medical Disputes). Given that victims of medical accidents could expect demage recovery only through lawsuits thus far, this act can be said to be a groundbreaking act. However, However, as 30% of the costs for such medical accident compensation projects are borne by those who have records of childbirth among the founders of health and medical institutions (Article 21 of the Act on Mediation of Medical Disputes), there has been a question about whether doctors are held responsible despite that the accidents such as the deaths of mothers and newborn babies occurred irresistibly without doctors' fault. However, recently, the Constitutional Court ruled that 'the range of founders of health and medical institutions' and 'share ratios of finances for compensation' in Article 46 (3) of the Act on Mediation of Medical Disputes' related to the imposition of the share of costs are institutional (Constitutional Court ruling dated April 26, 2018, 2015Heonga13, hereinafter referred to as 'the ruling in the case'). Although the ruling in the case was made based on only the principle of statutory reservation and the principle of ban on comprehensive authorization, this paper added a practical judgment. This paper proved that the share of costs in this case has the nature of burden charges in pursuit of study and does not infringe on the property rights of the founders of health medical institutions even in light of the principle of proportionality because there is a legitimate reason for imposing the burden charge. The imposition of the share of costs in the system for compensation for medical accidents occurred irresistibly is against the principle of liability with fault in part. However, the medical accident compensation projects are rational a national policy for the victims of medical accidents and the medical world clearly gains some benefits from the effect to terminate medical disputes. The expansion of finances for compensation through the payments of the share of costs will reduce the suffering and misunderstanding of victims of medical accidents occurred in the process of childbirth and will be very helpful to the construction of stable treatment environments of medical workers by quickly establishing the medical accident compensation projects as such.

The objective of this study was to determine the effect of bacterial inoculation (Lactobacillus plantarum or combo inoculant mixed with Lactobacillus plantarum and Lactobacillus buchneri) and addition of fibrolytic enzyme on chemical compositions and fermentation characteristics of whole crop barley (WCB) and triticale (TRT) silage, their ruminal in vitro fermentation, and digestibility. In TRT silage, enzyme addition significantly (p<0.01) decreased NDF content compared to no enzyme addition treatment. Organic acids such as lactate and acetate contents in WCB and TRT silages were significantly (p<0.01) higher compared to those in the control. Particularly, lactate content was the highest in L. plantarum treatment. Fibrolytic enzyme treatment on both silages had relatively higher lactic acid bacteria content, while mold content was lower in both treatments compared to that in the control. In vitro dry matter digestibility was generally improved in WCB silages. It was higher (p<0.01) in TRT with mixed treatment of L. plantarum, L. buchneri, and enzyme compared to others. In vitro ruminal acetate production was relatively higher in treatments with both enzyme and inoculant additions compared to that in the control. Therefore, the quality of silage and rumen fermentation could be improved by inoculants (L. plantarum and L. buchneri) regardless whether whole crop barley (WCB) or triticale (TRT) silage was used. Although it was found that fibrolytic enzyme addition to both silages had various quality and rumen fermentation values, further study is needed.

To obtain the basic data for commercial 10% salted egg yolk for mayonnaise preparation, 3 types of egg yolks [pasteurized egg yolk (Yolk A)-not salted, pasteurized before salting (Yolk B)-salted, and pasteurized after salting (Yolk C)-salted] were prepared, and the changes in quality characteristics of these egg yolks with frozen storage were tested. The results obtained were as follows; Yolk A gelatinized during frozen storage, thus could not used for mayonnaise preparation. The viscosity of the egg yolk increased $3{\sim}5$ times after salting. Viscosity of the salted egg yolk increased with frozen storage time. Viscosity of Yolk B was higher at $-20^{\circ}C$ than $-15^{\circ}C$. Viscosity of Yolk C, however, was higher at $-15^{\circ}C$ than $-20^{\circ}C$. Frozen storage of pasteurized salted egg yolk showed some effects on the emulsification capacity. The effect, however, was smaller than that of unpasteurized salted egg yolk. Microbes of salted egg yolk were decreased with frozen storage, but there was no difference between Yolk B and Yolk C. It was suggested that commercially pasteurized 10% salted egg yolk for mayonnaise preparation can be successfully stored for 12 months at the temperature of $-15{\sim}-20^{\circ}C$.

This study investigated the antioxidant and nitric oxide (NO) inhibition effects of three domestic and seven foreign fermented black tea 70% ethanol extracts. Bosung showed the highest total polyphenol and tannin contents. Jeju showed the highest total flavonoid contents. The theanine content was higher in Hadong (651.50 mg%) than in foreign fermented black tea. At 25 ㎍/mL, the domestic fermented black tea extract showed the highest DPPH and ABTS racial-scavenging activities, reducing power assays. Domestic fermented black tea showed higher NO inhibitor activity than foreign black tea at 50 ㎍/mL. Bosung black tea extract showed an increase in SOD-1 level (1.39-fold) compared to the LPS-only group. Bosung and Jeju decreased the GST protein by 1.52- and 1.46-folds, respectively, compared to the LPS-only group. Thus our results suggest that domestic fermented black tea (Bosung, Jeju, and Hadong) are effective antioxidants in RAW 264.7 cells.
