We report the distance modulus of nearby dwarf elliptical galaxy NGC 147 estimated from the Tip of Red-giant Branch (TRGB) method applying to the color-magnitude diagrams and luminosity functions in the near-infrared JHK bands. Apparent magnitudes of TRGBs in each band are obtained by applying Savitzky-Golay filter to the luminosity functions, and the theoretical absolute magnitudes are estimated from Yonsei-Yale isochrones. The derived values of distance modulus to NGC 147 are $(m-M)=23.69{\pm}0.12,\;23.78{\pm}0.17,\;and\;23.85{\pm}0.22\;for\;J,\;H,\;and\;K$ bands, respectively. Distance modulus in bolometric magnitude is also derived as $(m-M)=23.87{\pm}0.11$. We compare the derived values of the TRGB distance modulus to NGC 147 in the near-infrared bands with the previous results in other bands.

The influence of lysophosphatidylethanolamine (LPE) on anti-senescence of melon leaves and the change in fruit quality during the storage at low temperature were studied. In most of the crops, freshness of leaves is important factor for characteristics of fruits, such as sugar contents, color, and firmness. Melon ($Cucumis$ $melo$ L. cv. Prince) plants were sprayed with LPE at 5 and 3 weeks before commercial harvest. In upper part, LPE treatment showed slight high number of fresh leaf compared to no treatment (None). However, in lower part, LPE resulted in apparent inhibition effect on senescence, showing that lower side of melon plant kept fresh upon LPE application up to about 30%. The SSC of melon treated with LPE was similar to that of fruit from None at harvest. There was no change in soluble solids content (SSC) for all treatment during the storage at $7^{\circ}C$. There were no significant differences in firmness of mesocarp from melons given different treatments at harvest. The firmness of mesocarp from melon treated with LPE was higher than none after 2 weeks storage. The electrolyte leakage means for melon treated with LPE did not differ significantly from the means at initial storage after 2 weeks storage among the treatments. None increased 57% from its initial electrolyte leakage during storage. These results suggest that the application of LPE may have potential to inhibit senescence of leaves and maintain fruit quality during the storage in melon.

신문고지에 볏짚펄프를 혼합하였을 때 그 혼합비율이 포장 트레이의 물성에 미치는 영향을 조사하였다. 포장 트레이의 밀도는 볏짚펄프의 혼합비율이 증가됨에 따라 전반적으로 증가하는 경향을 보였다. 파열강도는 볏짚펄프의 혼합비율이 40%에 달할 때까지는 약간 감소하다가 그 이상의 혼합비율에서 점차 증가하는 경향을 보였으며 특히 볏짚펄프 단독으로 제조할 경우 트레이의 파열강도는 급격히 증가하였다. 포장 트레이의 압축강도는 볏짚펄프의 혼합비율이 40-80%되는 구간에서 비교적 낮게 나타난 반면 20%와 100% 수준에서는 비교적 높게 나타났다. 볏짚펄프의 혼합이 이루어진 처음 20% 수준에서 투기 시간은 급격히 감소하여 80%에 이를 때까지 약간 감소하다가 100% 수준에서 투기 시간이 증가하는 현상을 나타내었다. 볏짚펄프의 혼합에 따라 트레이 표면의 L값은 약간 낮아지고 b값은 뚜렷하게 증가하여 황색으로 변화함을 알 수 있었다.

Traditional costumes have evolved while reflecting the social, cultural and psychological values of the era. Costumes gain meaning by being worn that also allows their various symbolic meanings to be derived. Costumes worn in festivals by specific societies and organizations have especially apparent symbolism pertaining to their purpose. Most countries have traditional festivals that embody the country's distinct culture, history and traditions. These festivals are acts of consciousness expressing a special meaning of the community. Costumes represent a glimpse of life and culture during a festival period; in addition, the costume's style, color elements and decorations are expressions of community values and a distinct symbolic mechanism. Totemism (a significant element of these festivals) has been passed down for many generations. The current costumes for Totemism are distinct (compared to normal festival costumes) and embody a more symbolic meaning. This study deduces the exaggerated style, the concealment and disguise of the human body, and the pursuit of pleasure expressed in the Totemism costumes of regional European festivals. The symbolization theories of C. G. Jung and an analysis of Totemism costumes allow an understanding of their existential significance, their role as the medium between consciousness and unconsciousness, their meaning of symbolic transcendental unity, and their meaning of giving consciousness to the mind.

The aims of this study were to investigate the feasivility of analyzing a few sorting factors such as size, coloration and defect of apples with a monochrome image processing system and to find apparent properties which could be effectively used for apple sorting. The results are summarized as follows. 1. A computer program was made to analyze the projection area, coloration and defect of an apple with a monochrome image processing system. 2. The algorithm developed to compute the projedtion area of an apple was between on the proportional relation between a given reference area and the corresponding number of pixels, and the computing time was 0.74 to 0.82 second depending on the size of apple. 3. The coloration of an apple was expressed as the ratio of the gray value of a reference color to that of a given bounded area of the stem end surface (defined as coloration index), and the computing time was about 3.0 seconds with this algorithm. 4. Defect of an apple could be isolated by lowpass filtering and image subtraction but it took about 20 seconds in computing time. 5. The coloration of the Fuji apple could be classified into 3 to 4 groups by the coloration index and also, it was found that the correlation coefficient between the indices and sugar contents was 0.74. 6. The coloration index obtained from a given bounded area of the stem end side of the Fuji apple could represent the coloration of total surface with a correlation coefficient of 0.922.

This research investigated the difference in fabric preference over formal wear attire of 1999 Spring/Summer season between Korean and American female consumers. 25 Korean and 25 U.S.A. fabrics were used as fabric samples, and the respondents for the survey included 50 Koreans and 50 Americans in the 20s and 40s age groups. All six population groups showed similar dislike rankings toward the total fabrics (n=50). When the Korean fabrics and the U.S.A. fabrics were considered separately, the 20s and 40s age groups, especially between Korean 20s and Korean 40s, showed significant similarities in the dislike rankings. When the dislike preferences between Korean fabrics and U.S.A. fabrics were examined for different population groups, all the groups showed somewhat similar dislike rankings and in all cases U.S.A. fabrics were disliked more than the Korean fabrics. The most apparent difference in the physical characteristics of disliked fabrics was observed in jabric color. The Americans, especially the 40s age group, disliked fabrics with dark compound colors, whereas the Koreans in all age groups dislike fabrics close to bright pure colors.

A 1-year-old castrated male Schnauzer dog was presented with heart murmur. Auscultation revealed systolic murmur located at the left heart base (grade 5/6). There were no remarkable findings on thoracic radiographs. Two-dimensional echocardiography revealed subaortic tunnel-like obstruction at the entrance to the left ventricular outflow tract. Anterior mitral valve leaflet appeared to be tethered to septum with minimal motion. Chordae tendineae was abnormally thickened. Color Doppler analysis revealed turbulent flow starting below the aortic valve. Mitral regurgitation was presented during systole. Spectral Doppler recordings revealed high velocity flow through the aorta and mitral regurgitation. Based on echocardiographic examination, the dog was diagnosed with subaortic stenosis concurrent with mitral dysplasia. The patient was medicated with ${\beta}-blocker$ and diuretics. It has been doing well without apparent clinical signs at 2 year after the diagnosis.
