  • This paper comprised a review of published literature dealing with the evaluation of tobacco quality and usability. Evaluation of tobacco quality and usability seems to be difficult not only due to our inability to define them in simple and easily measurable term but also due to their relations to the profitability of tobacco companies and safety of comsumers. Chemical constituents and smoking taste and aroma of the tobacco represent the underlying basis for tobacco quality: however, tobacco is still purchased upon its physical appearance. Grade and value system is very convenient for evaluating the tobacco quality, if the system is based on the triangular relationship of physical appearance, chemical and smoking properties of tobacco, and also based on intrinsic quality of the tobacco independent of external influences. Grade and value system for tobacco in Korea is thought to be influenced by external factors besides intrinsic quality. Therefore, we have to concern new systems that could be supplement to, or replacement for currently available grade and value system.

  • As accidents with thermal runaway (TR) of lithium-ion batteries occur sporadically, the safety concern is the main obstacle that hinders the large-scale applications of lithium ion batteries. In most accidents, the TR of a single cell occurred first, and then dissipated the heat to the surroundings and triggered the TR of adjacent cells, resulting in TR propagation. Therefore, it is important to understand the mechanism of TR propagation and determine the key parameters during TR propagation in a battery pack. In this study, we performed a numerical analysis on the thermal runaway phenomenon by cathode active materials and appearance sizes in cylindrical lithium-ion batteries using a two-dimensional analysis model. The model results showed that the TR propagation of 21700 type cells (21 mm diameter, 70 mm height) occurs more rapidly than 46800 type cells (46 mm diameter, 80 mm height) and the LFP cell has higher thermal safety than the NCM cell. Especially, we found that the effect of the separator on the occurrence of TR is negligible.

  • We performed this study to understand the health status and food intake of North Koreans. Information was collected by individual closed in-depth interviews of 11 escapers from North Korea as well as books, newspapers and North Korean movies. Interviews were done from October, 1996 to May, 1997, covering their heights and weights, their appearance and disease, food system and intake of various main/side foods, concern about health and hygiene. North Korean's height and BMI were lower than those of South Koreans. Difference of BMIs between North and South Koreans was profound in middle aged women than in other age groups. Childrem showed many malnutrition appearances of moon face, large abdomem, arrow-like legs, flaky skin, decolored hair, etc.. Main foods in North Korea were rice-shaped corn, corn flour, wheat flour and wet noodle, and side foods were kimchi and/or soups and steamed soy paste. Food supply system there seemed not to work normally for many years, so foods, especially in cities, has been extremely short in government-operating shops, but some in private market. Many housewives were eager to make and sell simple snack food products, We noticed that North korea schools didn't check students' health even though their medical policy was based on preventive medicine. Their living environmental hygiene was shown to be oyt of control.

  • In the past year, the increasing concern about the biometric recognition makes the great activities on the security fields, such as the entrance control or user authentication. In particular, although the features of face recognition, such as user friendly and non-contact made it to be used widely, unhappily it has some disadvantages of low accuracy or low Re-attempts Rates. For this reason, I suggest the new approach to re-classify the classified data of recognition result data to solve the problems. For this study, I will use the typical appearance-based, PCA(Principal Component Analysis) algorithm and verify the performance improvement by adopting the re-classification approach using 200 peoples (10 pictures per one person).

  • The appearance regulations of many middle and high schools have received attention as the social concern over infringement of students' human right is heightened. This study aimed at examining students' perception of and attitude toward appearance-related regulations enforced by high schools in Seoul. For this purpose, a survey was conducted with 866 freshmen and sophomore students from six Co-Ed high schools located in Seoul. Students evaluated each of the 50 appearance-related regulations in terms of how strong they perceive the regulation is enforced in their school, how important they believe the regulation is, and finally, how much they actually observe it. The results indicated that regulations related to school uniforms are perceived important, and also were well-observed. Students, however, showed low levels of observance toward some regulations--i.e., regulations of hair styles or garments worn with school uniforms(coats, scarves, or turtlenecks). Students' personal characteristics were also found to influence their perception and observance of the regulations. This study has an implication for teachers and administers. For these regulations to be more effective, it was suggested that schools communicate the importance of appearance-related regulations to students and convince them, or consider revising their policies to reflect students' perspectives.

  • The concept of 'Picturing' is beyond the 'Illusion' of traditional art in the Digital Media era. It is a 'Suffering' of the 'Re-appearance' that is masquerade the 'Actual' as a 'Digital Apparition.' This study aims to concern the point of view on the above subject; the 'Picturing' through the analysis of communication problems in the digital era. To begin with, need to define the concept of 'Picturing' and how it is expected to have a role through the accessibility of medium use, intervention by body and images. Also, I suggest a new approach to 'Picturing' as a new mutual communication method. Body, Digital media, and Image. These three principles of 'Picturing' create huge benefits to our world/nature whether we want it or not. It seems to become more and more of powerful self-replicating organism. We have to be aware what sort of images are surrounding us and how transmitting it to where in/on our body via newest sophisticated media we use. 'Picturing' is an invasion of ordinary, no longer exists pleasure for body, no longer speaks intension of its next destination. It strongly self-grows and also controls us in the name of Digital media era. However, 'Picturing' is a mode of re-imaging activity and also suggestion of re-appearance practice.

  • The object of this study lies in reviewing of the western costume history in the light of the negative regulations concerning costumes and adornments. Readings related with the subject lead to the following findings; 1. the principal purpose of the sumptuary laws has relationship with the social stratification of the feudalism and the frequency of their occurrence is related with the formation of feudal system, its decline, the appearance of imperial regimes and the start of civil revolutions. 2. Sumptuary regulations spread westward with the flow of civilization, eg., in the sequence of Italy, swiss, France, Britain and new world. 3. Sumptuary laws are also found in abundance in the english colonies of America, and their object seems to be rather of the moral concern than class distinction of economical restriction.4. The reviewed sumptuary regulations are concerned with : A. Material gold or silver clothes, silks, ermine, marten or miniver furs, velvets, laces and embroies. B. Colors-Purple, scarlet and red. Other colors do not show consistent pattern of color-status symbol; C. Form-Length and width of headdresses, shoes, collars, trains or hoops. E. numbers of dresses allowed to be worn.

  • The propose of this study investigated the reproduction of color image displayed on a CRT monitor, for a range of different values of monitor gamma. We have used the GOG(gain-offset-gamma) model of the behavior of the CRT. Color difference have been computed in a color space, based on the CIELAB color appearance model. The 133 patch defined linearly color sample and 24 patch defined printing color target were used, and were subjected to the influence of nine different gamma value. The result show that neutral color is increasing the decrease range of luminance black color than white color. These results are of concern in the context of the "correct" display of color reproduction.
