  • We have investigated intensively an optical telescope with 76cm diameter and CCD camera system in astronomical observatory of Kyung Hee university, in order to maximize instrumental functions of our observational equipments and to construct a more reliable photometric system. And computer softwares AUTO DOME, KH CCD and KH PHO for astronomical image observations and their automatic photometries with high accuracy have been made for observers w use our observational system conveniently and efficiently. Throughout careful examinations of these programs, it has been proved that the observing time by our program is shorter than that by manual operations, so that, fast and accurate observations can be executed with ease. For open cluster NGC 7063 observed with S/N value of 350 or more by KH PHO, we have found the magnitude measurements of 11 object stars would show 0.007 magnitude difference, comparing with magnitude data from IRAF/APPHOT. From automatic photometry of eclipsing binary, AB And observed by our software, total 220 data points with good quality have been acquired during 8 hours and so we could make a better light curve than that obtained from any observational results by domestic photoelectric photometry system.

  • The expression of Bacillus subtilis $\alpha$-amylase from the phoA-amyE fusion gene in recombinant E. coli was investigated under various environmental conditions. The overexpression of cloned $\alpha$-amylase caused retardations in cell growth and synthesis of alkaline phosphatase (AP) from the chromosomal phoA gene. The change of culture temperature from $37^\circ{C}$ to $30^\circ{C}$ increased the specific activities of both $\alpha$-amylase and $\beta$-lactamase by six and two times, respectively, whereas the AP activity remained unchanged. The experiments with chlorampenicol (a translation inhibitor) suggested the enhancement of $\alpha$-amylase activity at $30^\circ{C}$, and this was partly due to the stability of $\alpha$-amylase itself. The further decrease of the temperature to $25^\circ{C}$ slowed down both the cell growth and cloned-gene expression rate. The $\alpha$-amylase activity showed a maximum at pH of 7.4 while alkaline phosphatase was most effectively produced at pH of 8.3.

  • While the women of the Korea Dynasty wore hat(笠子) and Mongsu(蒙首) on top of it when going out, the Yi Dynasty, due to more strict Contucian ethics and isolated way of life, had seen the development of the covering clothes, rather veil, for avoiding the opposite sex with diversity and both men and women began wearing PHO(coat), a Korean topcoat over the head and thurs called Changots, but originally PHO for men was named Changyi a men's outer coat. Neuwul(羅兀), like Mongsu(蒙首) of Korea Dynasty was a thin black hood worn on top of the Wowllip or a kind of skirt draped over the head and the latter was called Changots, very similar to Sgaechima, a kind of long hood formally worn by women. Meanwhile, local women wore a long veil with no arm sleeves dubbed Cheunyi(薦衣) But since western civilization and culture landed on Korea around the end of the 19th century, the women's social status has been raised to almost the same level with men and the way of life has changed towards openness, in which men and women have almost daily contact with one another, so these days we can hardly find such veil style covering clothes around us.

  • Objectives : The purpose of this study is to report the treatment of the Tinea corporis treated by Korean medicine. Methods : The skin lesion with keratin were scraped and placed on a slide glass, and the KOH solution was dropped and observed under a microscope. After the hyphae was confirmed, a ChoPho-bang was prescribed and applied twice a day. Results : In the KOH test performed again 3 weeks after treatment, no hyphae was found and the skin lesion was completely disappeared. Conclusions : For Tinea Corporis, the KOH test is recommended to distinguish it from other skin diseases, and application of ChoPho-bang is effective for treatment.

  • There is a lot of evidence of early port cities and small habitation sites along the Thai-Malay Peninsula's coastlines. These sites appeared on the trans-peninsular routes during the Maritime Silk Roads period, from 2,000 to 1,500 BP. The Thai-Malay Peninsula was mentioned in many documents as Suvarnabhumi (India), Aurea Chersonese (Greek), and Jin Lin (Chinese), meaning the Golden Land. Ptolemy's map displays that there were many port cities along this peninsula. It corresponds to the Milinda-panha, which depicts many port cities in Suvarnabhumi. Foreign documents primarily documented the presence of major port cities, while inland habitation sites received less recognition. This paper aims to reconstruct the trans-peninsular routes in order to understand their networks, connections, and roles. The second aim is to understand the hierarchy of each site. This paper will focus on two important settlements and high-value artifacts along three routes: the Kra Isthmus Route, the Pho Khao Thong and Tha Chana Route, and the Krabi to Surat Thani Route. I conducted an archaeological survey of these three routes and others during 2021-2023 under the Suvarnabhumi Studies Center, TASSHA Institute, and the Ministry of Higher Education, Science, Research, and Innovation.

  • RbsC of Escherichia coli is the integral membrane component of the high-affinity ribose transport system classified as the AraH family. To understand the function and structure of RbsC, the topology of RbsC was investigated by alkaline phosphatase fusion. Characterization of a total of 64 RbsC-PhoA fusions revealed that RbsC is composed of six transmembrane helixes and has three periplasmic and two cytoplasmic loops.(omitted)

  • The mating type a of yeast, Saccharomyces cerevisiae mutant with hmla2-102 and sir3-8ts was changed to type alpha by changing the growth temperature from 25C to 35C. A temperature-sensitive expression vector system was constructed using mating factor alpha1 (Mfalpha1) gene encoding alpha factor which is expressed in the type alpha cells. Vectors with different copy numbers were constructed by joining the promoter and pre or prepro-secretion single sequence of Mfalpha1 to promoterless PHO5' gene as a reporter gene.

  • Garlic (Allium sativum) has been used as a general food and a remedy in Oriental for a long time. Since garlic compounds have been also shown to inhibit growth of tumors and to modulate the activity of carcinogenesis, the effects of allicin on growth and survival in human gastric epithelial cells were evaluated by cell viability, cell cycle analysis and DNA fragmentation. Protein levels of cytochrome C, Bcl-xL, Bax and AIF were detected by Western blotting. Effects of recombinant VacA on caspase proteases activity were also determined. (omitted)

  • This study was conducted to redesign hotel robes based on Korean images. Hotel robes are furnished at many Korean hotels to increase the level of their guests' satisfaction toward their hotel services. The current hotel robe has several flaws in utility and design. Also, the robes register a low level on guests' satisfaction while generating high cleaning cost. Consequently, improvements in the hotel robes' material, motifs, style, and color were needed. The current one-piece, cotton towel weave robes used in hotels are white and pale. Half of the hotel guests never wear the hotel robes during their stay, because they are unattractive and most Korean hotels provide a robe similar in design. Furthermore, these robes are undistinguishable from those found at other countries. Nevertheless, Korean hotel managers feel that the hotel robe is an important tool to express its hotel image and to increase guests' satisfaction of their services. Most hotel managers and consumers agreed that it is necessary to design hotel robes based on Korean images. They believe that redesigning the hotel robes based on Korean images would induce hotel guests to wear them and at the same time feel part of the Korean traditional culture. The Korean traditional motifs of Taegug, Un (cloud), JuJag (phoenix), and Kumkwan (gold crown) were used in the new design of the hotel robes. The style of new hotel robes is the Korean traditional Pho of the Three Kingdoms. The colors of new hotel robes are white and pink. Forty-three examiners evaluated the newly designed robes for their aesthetic, symbolic and distinctional values. They concurred that the new robes were much better than the current ones.
