Objectives : This study was designed to establish a characteristic discrimination of internal and external morphological standard of original plants and herbal states in Pogostemonis and Agastachis Herba. Methods : In this studies, the external-internal morphological standards were determined by using stereoscope and butanol series. Results : 1. The external characteristics: Pogostemon cablin has hairs and brown-like in stem, elliptical fruit. On the other hand, Agastache rugosa has no hairs and red-like in stem, obovatic trigone fruit. 2. The physical characteristics: Pogostemon cablin is gray in whole, has hairs in stem and numerous hairs of ash in leaf. On the other hand, Agastache rugosa is yellow-green in whole, has no hairs in stem. Specially the latter has deep-green colour and numerous hairs presenting mostly at lower epidermis in leaf. 3. The physical characteristics in currents: Pogostemon cablin is brown, has hairs and round-like stem. On the other hand, Agastache rugosa is green or yellow-green, has no hairs and tetragon in stem. 4. The internal characteristics: Pogostemon cablin has progressed spongy tissue in epidermal cell of leaf and many rank of epidermal cell in stem. On other hand, Agastache rugosa has I rank palisade tissue in leaf and few rank of epidermal cell in stem. In the external shape, it was possible that herbs were distinguished according to artificial cIassification and that same genus-degree of relatedness among herbs could be distinguished by more precise and active observation. In the shape of real herbs, I compared current herbs in market with original herbs which were just collected or were on the course of drying. In addition, it was possible that the internal shape could be identified by using microscope after butanol series. Conclusion : Though it was impossible to make distinction of herbs which are not current in my search contents, this search contents will be a standard for applying herbs in the future. An Additional standard establishment including physiochemical reaction and gene research is required in order to supplement the fault of this search.

The finance of the National Health Insurance(NHI) in nearly every Nation in the world has been traditionally based on premiums of the workers and employers. But in Korea, the government has been guaranteeing financial supports to regional health corporations. After the unification of the different corporations in the NHIC, the government will not have to give financial support to the NHIC. Then this will be a serious financial challenge to NHIC, which has usually had financial deficit. The purpose of this paper is to review the problems of the premium based financing of the NHI and to exam whether such problems will be solved through the financial support from the state to the NHI. The analysis in this paper focused on five viewpoints; 1) work relatedness 2) redistribution effect 3) financial burden of business firms through the premium 4) risk pooling 5) management hegemony of the NHI. As a result, it was found that there are many problems in every five aspects and these problems could be solve through the financial aid from the state. But, it does not without any restriction mean to suggest that the financing mode of the korean NHI should be wholly transformed to a tax based financing mode. Because there are many things to be considered in oder to alter the financing mode of the NHI. Nevertheless, this paper would give a logical background to enlarge the financial aid form the state to NHI, or at least, to maintain it at a present level.

Infectious hematopoietic necrosis virus (IHNV) is the causative agent of IHN, one of the most serious viral diseases of salmonid fish. In this study, glycoprotein (G) gene nucleotide sequence of isolated IHNV RtWanju09 from Jeollabuk-do province was analyzed to evaluate their genetic relatedness to worldwide isolates. As the result, it was revealed that IHNV RtWanju09 isolate belongs to JRt Shizuoka lineage with IHNV RtPy91 and RtJe00. The genetic diversity of G gene between RtWanju09 isolate and RtPy91 isolate from Gangwon-do province was 1.77% and maximum nucleotide diversity among the JRt Shizuoka lineage in Korea was 3.03% during the past 20 years, supporting that the continuous evolution has been occurred among JRt Shizuoka isolates. It was believed that IHNV RtWanju09 isolate has been introduced by the movement of contaminated eggs with IHNV from Gangwon-do to Jeollabuk-do by the reason that the eyed eggs in Jeollabuk-do province used to be obtained from Gangwon-do province. In this study, the domestic transfer of IHNV was firstly investigated by the transfer history of eggs and the phylogenetic analysis using IHNV glycoprotein gene sequence.

Objectives: In this study, we assessed respiratory hazards in the working environment as the work-relatedness of occupational diseases were examined. Methods: The subjects of the study were three Korean meat roasting restaurants, one Chinese restaurant, and two cafeterias. Measurement items were total dust, respirable dust, fine dust (PM_2.5), PAHs, TVOCs, temperature, humidity, carbon monoxide, carbon dioxide, and nitrogen dioxide. Results: The concentration of total dust and respiratory dust in the restaurant was low. Most PAHs were undetectable, but some Napthalene and Acenaphthylene was detected. Thirteen kinds of PAHs were detected in one sample of roasted meat, and Benzo(a)pyrene was 1.496 ㎍/㎥. PM_2.5, TVOCs, CO, and CO₂ were instantaneously high, but the average concentration was low. NO₂ was not detected. Conclusions: The results show that harmful substances such as PM_2.5, PAHs, CO, and TVOCs were generated in the air in the catering industry. When roasting meat, Benzo(a)pyrene, a carcinogen related to lung cancer, was generated among PAHs. Lung cancer can occur when working for a long time in such a working environment. Therefore, it is necessary to improve the working environment for the health of restaurant workers, and it is necessary to evaluate the concentration of harmful substances by cooking method through further research.

To determine phylogenetic relatedness of four silk-producing silkmoths (B. mori, B. mandarina, A. yamamai and A. pernyi), internal coding region of arylphorin which is a storage protein in hemolymph protein of insects were amplified by polymerase chain reaction and then sequenced and compared each other. The nucleotide composition was biased toward adenine and thymine(59% A+T) and a strong bias for use of C in the third position of codons was found for Phe and Tyr. Together TTC(Phe) and TAC(Tyr) account for about 16.8% (10 for TTC and 8 for TAC) of all codon usage. The nucleotide similarity of arylphorin gene from B. mori showed 99%, 98% and 97% homology with those of B. mandarina, A. yamamai and A. pernyi, respectively. Also, the nucleotide sequence of arylphorin gene from B. mandarina showed 98% and 97% homology with those of A. yamamai and A.pernyi, respectively. Between A. yamamai and A. pernyi, the sequence homology was 97%. The deduced amino acid sequences in B. mori, B. mandarina and A. yamamai showed almost 99% homology. Although the aryphorin gene provided insufficient variability among the four insect species, A UPGMA tree is generated that supported the monophyly of silk-producing insects, with M. sexta placed basal to it. It is suggest that silk-producing insects have a close relationship and a homogeneous genetic background from comparison with those of other insects.

Local governments' spatial information policies are very important in that it can increase the relatedness to upper policy regarding the share, openness and converged utilization of spatial information and contribute to voluntary participation and creative uses linked to big data. However, local governments' spatial information policies require enhancement since it need to update framework spatial data, to derive spatial information service and to share the data. In this research, we compared the spatial information policies and related systems of central and local governments, and analyzed the local governments' spatial information policy enforcement plans and the Seoul metropolitan government's utilization survey on 32 spatial information systems. In the result, for the improvement of local governments' spatial policies, on-demand updating of base map using the as built drawings linked to field work departments, securing up-to-date public domain spatial information through the NSDI system, sharing of spatial information based on the spatial information platform and benchmarking of best practices related to the spatial information based policy participation are suggested.

Purpose: This study examined the impact of a drinking reduction program on drinking motivation, drinking refusal self-efficacy, and problematic drinking behaviors in college students with problematic drinking habits. Methods: This study incorporated a non-equivalent control group prepost-test design. Study participants included 58 college students who scored 12 or more in the AUDIT-K test (Alcohol Use Disorders Identification Test-Korean version) (experimental group: 30; control group: 28). The intervention consisted of eight sessions and was conducted once a week. It was designed to promote autonomy, competence, and relatedness-the three elements of basic psychological needs in self-determination theory. The participants were assessed before the intervention, immediately after, and four weeks post intervention. Data were collected from October 12 to December 31, 2017. The analysis employed the chi-square test, Fisher's exact test, independent t-test, and repeated measures ANOVA using SPSS/WIN 22.0. Results: The mean age of participants was 21.8 years. There were 30 men (51.7%) and 28 women (48.3%). The differences in drinking motivation, drinking refusal self-efficacy, and problematic drinking behaviors were statistically significant for the group by time interaction (F = 42.56, p < .001; F = 54.96, p < .001; F = 39.90, p < .001, respectively). Conclusion: The findings indicate that the intervention effectively decreases drinking motivation, increases drinking refusal self-efficacy, and decreases problematic drinking behaviors. It can be an efficient strategy for college students with problematic drinking habits to enhance their self-determination ability.

Objective: To carry out a comprehensive production planning of the existing Rongchang pig population from both environmental and genetic aspects, and to establish a closed population with stable genetic diversity and strict pathogen control, it is necessary to fully understand the genetic background of the population. Methods: We genotyped 54 specific pathogen free (SPF) Rongchang pigs using the Zhongxin-1 Porcine Breeding Array PLUS, calculated their genetic diversity parameters and constructed their families. In addition, we also counted the runs of homozygosity (ROH) of each individual and calculated the value of inbreeding coefficient based on ROH for each individual. Results: Firstly, the results of genetic diversity analysis showed that the effective population size (N_e) of this population was 3.2, proportion of polymorphic markers (P_N) was 0.515, desired heterozygosity (H_e) and observed heterozygosity (H_o) were 0.315 and 0.335. H_o was higher than H_e, indicating that the heterozygosity of all the selected loci was high. Secondly, combining the results of genomic relatedness analysis and cluster analysis, it was found that the existing Rongchang pig population could be divided into four families. Finally, we also counted the ROH of each individual and calculated the inbreeding coefficient value accordingly, whose mean value was 0.09. Conclusion: Due to the limitation of population size and other factors, the genetic diversity of this Rongchang pig population is low. The results of this study can provide basic data to support the development of Rongchang pig breeding program, the establishment of SPF Rongchang pig closed herd and its experimental utilization.

The purpose of this study was to introduce the differential standard of Mok-Hyaeng Radix species. We established the classificatory standard according to the external and internal morphology and the pattern in 4 kinds of Mok-Hyaeng Radix. The results follow: 1. On the external morphology, Radix of Vladimiria souliei had a sticky material in the head of roots and it was yellowish white in the cut surface. It attached to teeth during chewing. Radix of Aucklandia lappa (=Saussurea lappa) was dark grayish brown and was grayish brown in the cut surface. It had special odor and was not attache to teeth chewing it. On the other hand, Radix of Inula helenium was dark brown. In the cut surface, cortical layer was different from wood layer. Radix of Aristolochia contorta was yellowish brown. In the cut surface, it was not smooth and cortical layer was different from wood layer. 2. On the internal morphology, Radix of Vladimiria souliei had many fascicular fibers and scattered large oil chambers in the bast ray, xylem ray, and parenchyma. On Radix of Aucklandia lappa (=Saussurea lappa), it was difficult to find out the trace when the cork layer was exfoliated. The cambium formed circle and the large oil chambers were scattered in the phloem and xylem. On the other hand, external cortical layer of Radix of Inula helenium was detached and cambium was formed to indistinct circle and large oil chambers were scattered in the phloem and xylem. On Radix of Arustolochia contorta, the large oil chambers were scattered in the surface later, bast part was relatively broad and cambium formed circle. 3. On the TLC pattern, Radix of Aristolochia contorta, Inula helenium, Aucklandia lappa, and Vladimiria souliei were chromogenic to violet and purple according to sulfuric acid colour pattern, especially faint on Aristolochia contorta. 4. On the pattern analysis of HPLC, we compared the content and the pattern of constunolide and dehydrocostus lactone, Radix of Aucklandia lappa was similar to Radix of Vladimiria souliei and Radix of Aristolochia contorta was similar to Radix of Inula helenium. On the total HPLC component pattern, constunolide and dehydrocostus lactone were similar in all four types, but it showed the Rf 5-6 peak was only in Radix of Aristolochia contorta, not in Radix of Inula helenium, Aucklandia lappa, and Vladimiria souliei. It is considered the results of this study will be furnished the basis to succeeding studies and it is needed to extensive comparative study for the same genus-degree of relatedness.
