Regional production structres are investigated through an estimation of three-input(labor, capital and material) translog cost function. The estimation uses the pooled data in which time series data of 1970-1990 are combined with cross-sectional data corresponding to firm sizes. The empirical finding are the following: (1) the factors are Allen substitutes each otner in general except Pusan and a couple of regionss, and (2) estimates are very small in its absolute value irrespective of the regions. The low elasticity estimates of this study implies that substitytability among the three inputs are very weak in the regional manufacturing production compared to that in the national production. Seoul-Kyungki metropolitan area produces not only the smallest elasticities but relatively stable estimates without much fluctuation between the sub-regions of the area.

In this paper we consider a polling system with two classes of stations; high priority and low priority. High priority stations are polled more frequently than low priority stations. We derive an exact and explicit formula for computing the mean waiting times for a message when the arrival processes are batch Poisson. In general the formula requires to solve two sets of simultaneous equations By specializing them to the case of two priority classes we greatly reduce the number equations and provide a simple formula for mean waiting times. We apply the results to a data communication processing system and show that the overall mean waiting time can be reduced by using priority polling.

Objectives: This study examined demographic factors hampering access to healthcare at hospitals and suggests policy approaches to improve healthcare management in Thailand. Methods: The data for the study were drawn from a health and welfare survey conducted by the National Statistical Office of Thailand in 2017. The population-based health and welfare survey was systematically carried out by skilled interviewers, who polled 21 519 384 individuals. The independent variables related to demographic data (age, sex, religion, marital status, education, occupation, and area of residence), chronic diseases, and health insurance coverage. The dependent variable was the degree of access to healthcare. Multiple logistic regression analysis was subsequently performed on the variables found to be significant in the univariate analysis. Results: Only 2.5% of the population did not visit a hospital when necessary for outpatient-department treatment, hospitalization, or the provision of oral care. The primary reasons people gave for not availing themselves of the services offered by government hospitals when they were ill were-in descending order of frequency-insufficient time to seek care, long hospital queues, travel inconvenience, a lack of hospital beds, unavailability of a dentist, not having someone to accompany them, and being unable to pay for the transportation costs. Multiple logistic regression analysis showed that failure to access the health services provided at hospitals was associated with demographic, educational, occupational, health welfare, and geographic factors. Conclusions: Accessibility depends not only on health and welfare benefit coverage, but also on socioeconomic factors and the degree of convenience associated with visiting a hospital.

This study has investigated the stream of consciousness and the actual conditions of tattoo. A survey of 466 people has found that female prefer tattoo, and a group of age between 21 and 41 and professionals are more interested in it. Both past and present of attitude consciousness about tattoo understand it dynamic and severe. However, it is considered as a feminine these days, whereas it had been understood as a masculine image in the past, which means a decrease of symbolism by gender. Also, in comparison with the past, the current thoughts on tattoo are getting hopeful and affirmative that we could know the attitude about tattoo changes. A survey of 106 tattooists shows that most people get a temporary tattoo, and permanent, semi-permanent tattoo came next. The most preferred area were eyebrows, are, shoulder, forearm, back of hand and waist, and a main reason of getting tattoo were for beauty and ostentation. For the level of satisfaction, 70.7% of the people polled said they were satisfied with it, and male preferred a pattern of animal, geometric and plant while female preferred a pattern of plant, animal, and geometric in order. So far, by the lack of basic information and data, efficiency value of tattoo is in negative view. Thus, it would be required to enhance a level of understanding tattoo focusing on the positive side like a new life style, sense of value, sensation and emotion of contemporary people, and generalize it by providing various technical information and knowledge of beauty image effect accompanied with tattoo.

This study, to investigate the state of PVW among the clinical dental hygienists and its determinants, has polled 322 clinical dental hygienists working in Daegu, Kyung buk province, and Ulsan. Data were collected by self-administrated questionnaire. A SPSS 12.0 for Windows was used for statistical analysis. The obtained results were as follows: 1. The average of PVW among the respondents was 3.43. 2. The area average of PVW determinants was as follows; job significance, 3.31, process efficiency, 3.42, product usefulness, 3.32, vision realizability, 3.53, social recognition, 3.23 and the total average, 3.36. 3. The married have higher PVW than the unmarried in all areas(p=.012, p=.008, p=.036, p=.007). 4. As for working experience, in the case of perceived self value, those having 1~2 years experience have the highest PVW(p=.000), apart from perceived self value, those having over 6 years experience have the highest PVW in all areas(p=.015, p=.001, p=.002). Relating to the task, those working in the patient consulting and managing part have the highest PVW, relating to the annual salary, those having over 25 million won have the highest PVW(p=.000, p=.000, p=.001, p=.000). 5. The relationship between PVW and PVW determinants, in all respects, is meaningful, so it was found that the higher determinants are, the higher PVW is. 6. The whole explanation variate of PVW determinants was meaningful in PVW, perceived self value, value fulfillment emotion, respectively representing 38.8%, 55.6%, 61.5%(pE.001). PVW of clinical dental hygienists should be considered as a significant criterion of indivisual and organizational effectiveness. To improve effectually PVW of the clinical dental hygienists, there is need to establish culture in a system of hospital that redound to their social recognition.

Korean ginseng (Panax ginseng) is a dicotyledonous, medicinal, perennial plant belonging to the genus Panax of the family Araliaceae. We investigated the occurrence and incidence of plant viruses in Panax ginseng in Korea. A total of 656 leaf samples were combined into one and total RNA was extracted from the polled sample, using RNA sequencing (RNA-Seq), a metatranscriptome analysis of the plant virome was conducted. The virus present in Panax ginseng was confirmed by reverse transcription polymerase chain reaction (RT-PCR) assay using virus-specific primers. In RNA-Seq data analysis, the multiplication protein of four viral contigs including Aristotelia chilensis virus 1 (AcV1), Turnip mosaic virus (TuMV), Watermelon mosaic virus (WMV), and Tobamovirus multiplication protein were discovered. From our metatranscriptome analysis and RT-PCR assay, TuMV and WMV were detected, whereas the three viruses reported in China such as tomato yellow leaf curl China virus; panax notoginseng virus A; and panax virus Y were not found in this study. The distribution of domestic ginseng viruses seems different from that recorded in China. Overall, this is the first plant virome analysis of Panax ginseng in Korea.
