  • 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 purpose of the study was to investigate the effects of the characteristics of dietitians, the characteristics of school food services, equipment ratio of HACCP facility/equipment and perception of barriers to HACCP implementation on external and internal audit of food safety/sanitation management performance in school food service. An e-mail survey was conducted with 144 dietitians in Gyeongbuk Province. A response rate was 57.6% (N = 83) and data was analyzed using SPSS windows (ver. 12.0). Dietitian perceived facilities/equipment-related and stakeholder-related as the big barriers in implementing a HACCP system. Total scores of sanitation/safety management performance for external and internal audit were similar at 92 and 91 out of 100, respectively. 'Facilities/equipment' and 'HACCP system' categories in both external and internal audit were rated the lowest. As dietitian perceived facilities/equipment-related (p < 0.001) and stakeholder-related (p < 0.05) barriers to HACCP implementation were greater, the scores of the external and internal audits were significantly lower. As dietitian perceived barriers for all categories were greater, the scores of internal audits were significantly lower (p <0.05). As a result of multiple regression analyses, the scores of the external audit was positively associated with career as a school food service dietitian, but was negatively associated with barriers related to facility/equipment, while the scores of the internal audit was negatively associated with barriers related to facility/equipment and employees. This study suggests that supporting programs on securing the facilities/equipment and employee training are needed for successful HACCP implementation in school food service.

  • This study aimed to propose a fashion design development method using the external and internal characteristics of the flower and bird paintings in traditional Korean folk paintings. As a research method, external and internal characteristics of folk paintings were examined through previous studies and literature research, and folk painting patterns were developed into digital textile designs. Five 3D digital fashion designs were proposed using the CLO 3D program. The external characteristics of folk paintings were as follows: simplification and planarization of object representation, diversification of viewpoints, ignorance of perspective and symmetrical enumeration, strong colors and contrast effects, and the simultaneous representation of time. The internal characteristics of folk paintings were as follows: symbolic meaning, the beauty of free humor, modest aesthetics, complexity of reality and fantasy, and desire of shamanism. The results are as follows. Firstly, the flower and bird painting was a decorative painting style that emphasized decorative beauty and was suitable for developing fashion designs with Korean originality because of the symbolic and internal meanings. Simple layouts and bold free-spirited representations were effective ways to fill the screen with objects and gave the pattern a decorative effect. Secondly, developing a virtual clothing prototype based on digital design method using the external and internal characteristics of folk paintings and producing realistic fashion designs suggest the integrated use of science and technology, embodying modern fashion through the combination of digital fashion content and traditional cultural content. Thirdly, as a result of the development of 3D digital fashion designs, an eco-friendly and sustainable fashion design methods with virtual clothing can suggest a design development method that saves time and cost in the fashion design process while considering the environment.

  • Purpose - This study empirically analyzes the impact of the internal and external network embeddedness of foreign subsidiaries and local market characteristics of the host country on the CEO selection whether or not to appoint an expatriate as the CEO of a foreign subsidiary. Design/methodology - To conduct an empirical analysis, we obtained a list of the headquarters of Korean MNCs from the Korea Chamber of Commerce and Industry. Based on the list of HQs, we identified a final list of overseas subsidiaries of Korean MNCs that have entered the world from KOTRA (Trade-Investment Promotion Agency for Korea). Then we conducted an empirical analysis based on the results of 391 questionnaires by employing logistic regression analysis. Findings - The results of empirical analysis are as follows. First, the higher the subsidiary's internal network embeddedness, the higher the tendency appoint an expatriate as the CEO. Second, the higher the volatility of the local market, the higher the tendency to appoint an expatriate as the CEO. Third, the stronger the competition in the local market, the lower the tendency to appoint a PCN. Originality/value - This study has significant theoretical implications in that it examines the link between the internal and external embeddedness of overseas subsidiaries and the appointment of parent country nationals (PCNs) as the CEO that prior research has not examined.

  • The $Na^+-and\;K^+-induced\;Ca^{++}$ release was measured isotopically by millipore filter technique in pig heart mitochondria. With EGTA-quenching technique, the characteristics of mitochondrial $Ca^{++}-pool$ and the sources of $Ca^{++}$ released from mitochondria by $Na^+\;or\;K^+$ were analyzed. The mitochondrial $Ca^{++}-pool$ could be distinctly divided into two components: internal and external ones which were represented either by uptake through inner membrane, or by energy independent passive binding to external surface of mitochondria, respectively. In energized mitochondria, a large portion of $Ca^{++}$was transported into internal pool with little external binding, while in de-enerigzed state, a large portion of transported $Ca^{++}$ existed in the external pool with limited amount of $Ca^{++}$ in the internal pool which was possibly transported through the $Ca^{++}-carrier$ present in the inner membrane. $Na^+$ induced the $Ca^{++}$ release from both internal pool and external pool and external binding pool of mitochondria. In contrast, $K^+$ did not affect $Ca^{++}$ of the internal pool, but, displaced $Ca^{++}$ bound to external surface of the mitochondria. When the $Ca^{++}-reuptake$ was blocked by EGTA, the $Ca^{++}$ release from the internal pool by $Na^+$ was rapid; the rate of $Ca^{++}-efflux$ appeared to be a function of $[Na^+]^2$ and about 8mM $Na^+$ was required to elicit half-maximal velocity of $Ca^{++}-efflux$. So it was revealed that $Ca^{++}-efflux$ velocity was particulary sensitive to small changes of the $Na^+$ concentration in physiological range. Energy independent $Ca^{++}-binding$ sites of mitochondrial external surface showed unique characteristics. The total number of external $Ca^{++}-binding$ sites of pig heart mitochondria was 29 nmoles per mg protein and the dissociation constant(Kd) was $34{\mu}M$. The $Ca^{++}-binding$ to the external sites seemed to be competitively inhibited by $Na^+\;and\;K^+$; the inhibition constant(Ki) were 9.7 mM and 7.1 mM respectively. Considering the intracellular ion concentrations and large proportion of $Ca^{++}$ uptake in energized mitochondria, the external $Ca^{++}-binding$ pool of the mitochondria did not seem to play a significant role on the regulation of intracellular free $Ca^{++}$ concentration. From this experiment, it was suggested that a small change of intracellular free $Na^+$ concentration might play a role on regulation of free $Ca^{++}$ concentration in cardiac cell by influencing $Ca^{++}-efflux$ from the internal pool of mitochondria.
