The purpose of this study is to clarify motives, itinerary and general patterns associated with the traveling of the upper class in the Chosun Dynasty based on twenty travel accounts of Mt. Chungryang. In addition, previous studies were referred to in order to compare these trips to Mt. Chungryang with those which were undertaken to Mt. Kumgang so as to identify the unique characteristics of those involved with the trips to Mt. Chungryang and of these trips in themselves. Through this process, unique characteristics, such as the travelers' academic backgrounds and place of origin, as well as how these travelers' relationship with their teachers influenced the motivation for these trips were uncovered, as were the processes through which travel schedules and companions were selected. Moreover, the researcher identified similarities and differences between the travel of Mt. Chungryang and Mt. Kumgang in terms of the travelers' motivation for the trip, the transportation methods they employed, and the kind of accommodation they sought. Moreover while similarities were also uncovered with regards to the travel practices of the literati class during this time, differences emerged in terms of their travel dates and schedules.

This research was focused on observing the effect of Makgeolli's selection attributes on customer satisfaction, recommendation intention, and repurchase intention. The purpose of this study was to examine to present a marketing-related suggestion by finding the components that needs to be discussed in order to satisfy the customer and lead to positive word of mouth and repurchasing in the perspective of a corporation. The evidence to achieve the research purpose can be summarized as below. To begin with, the causes of Makgeolli's selection attributes were classified into 9 types, which are design and ad image, expertise and tradition, drinking experience and in harmony with food, taste and freshness, materials and origin, brand image, flavor and color, alcoholic and nutrition, and finally price and recommendation. And it showed up that the average importance of the taste and freshness is the highest. Moreover, the study on the Makgeolli's state of being potable showed up that the drinking number was no more than once a month, and one drink was almost all less than a bottle. The drinking place was usually tavern, and word of mouth was the most often used information medium that contacted Makgeolli. The potential of the Makgeolli's globalization is 80.6% which added positive and very positive, that enables us to infer that the Makgeolli's global dependency is very high. Third, from the 9 types of classification mentioned before, taste and freshness, and price and recommendation were proved to be influential in satisfaction, and recommendation is affecting the repurchase intention and the recommendation intention.

The purpose of this study was to investigate the relationships among recognition, preference, and purchasing characteristics for Changnyeong onions and garlic as well as festival satisfaction among participants at agricultural product festivals in the Changnyeong region. Results showed that festival satisfaction of 'place of festival' was highest while 'convenience facility & event contents' earned the lowest scores. Most subjects (90.5%) had purchased Changnyeong agricultural and processed products. A major purchasing type was fresh agricultural products (66.7%). The pathways to recognize Changnyeong agricultural products were mostly 'promotion by related institutions' (22.0%), 'family relatives' (20.8%), 'mass media' (16.6%), and 'festivals and events' (16.1%). The most considered factors for purchasing regional products were 'geographical origin' and 'ingredients'. Changnyeong onion showed higher scores for recognition and preference and rate of purchase experience and intention than for garlic. The correlation coefficients of recognition and preference for onion and galic were 0.603 (p<0.001) and 0.598 (p<0.001), respectively. The explanation power ($R^2$) of related variables for purchase of Changnyeong onions was 0.258. The regression coefficients (${\beta}$) for 'recognition', 'preference' and 'convenient facility & event contents' were positive, whereas the regression coefficient for 'price' was negative. Recognition, preference, and convenient facility & event contents with garlic purchase showed a positive relationship ($R^2$=0.253). The most effective promotion method to increase sales of Changnyeong agricultural products was 'local festivals and events' (27.8%).

The causes of the fire casualties were the heat burns, contacted by flame, before the period of industrialization. According to the economic has been developed drastically since 1990, residing space has been become bigger and sophistication and interior finishing materials have been diversified. Therefore, the suffocation casualties, caused by inspiration of toxic combustion gases, have been more increased than the flame casualties in recently. Also, the arson casualties have been increasing with the increasing of insurance crime to take the Insurance money. According to National Emergency Management Agency announcement, 31,778 fires was occurred nationwide in 2006 and the total casualties were 2,180 occurred. 446 persons were died among them. Because the exact investigation of fire, occurred the death, is very especially important that civil and criminal cases will be happened. Therefore, we studied about the cause of fire, the place of origin, and the group of casualties age on the axies of fires, which were occurred recently. And the identification method of fire casualties, the human behavior characteristic, the flame casualties and the suffocation casualties at fire scene.

In this paper, we examine how secondary school mathematics textbooks on calculus introduce the history of calculus. In order to identify the problem, we consider the Babylonian integration by trapezoidal rule, which was made to calculate the location of Jupiter in 350-50 B.C., and the integration by the method of the rotating plate of ibn al-Haytham in Egypt, about 1000 years. In conclusion, our secondary school mathematics textbooks describe Newton and Leibniz as inventing calculus and place their roots in ancient Greece. The origin of the calculus is in Babylonia and the Faṭimah Dynasty (909-1171) (Egypt) and it is desirable that the calculus is developed in Europe after the development of the power series in India, and that the value of Asia Africa is introduced in the textbooks.

We have investigated the prevalence of canine heartworm (Dirofilaria immitis) infection among 100 mixed-breed dogs raised in Chonnam Province (Koheung, Posung, Changheung, and Hwasoon) and 100 dogs randomly selected from visiting dogs to the College of Veterinary Medicine, Chonnam National University for routine physical examination. Blood samples taken from dogs were examined for the presence of Dirofilaria immitis microfilaria by the modified Knott's test, and an antigen test which was based on the sandwich ELISA(DiroCHEK(equation omitted), Synbiotics, Inc., San Diego, California, USA) was used to detect the adult heartworm-specific antigen from serum samples. The results were then compared with those of the modified Knott's test. Five(2.5%) of the 200 examined dogs were microfilaria-positive, while 8 dogs(4%) were anti-gen-positive, which suggested that the antigen test was more sensitive than the microfilarial test in detecting heartworm infection. All dogs that were microfilaria-positive were also antigen-positive. The place of origin of the heartworm-positive dogs were of Naju (4/26, 15.4%), Koheung(3/32, 9.4%), and Hwasoon (1/19, 5.3%), while none of dogs raised in Kwangju, Posung, and Changheung areas were infected with the parasite. Although not significant, more infected dogs were observed in older ages, while the difference in infection rate between male (4/98, 4.1%) and female (4/102, 3.9%) was not recognized. Our results indicated that a relatively low infection rate was observed in dogs raised in Kwangju and Chonnam area compared to the infection rate reported previously in other areas of South Korea.

Ameloblastoma is a rare epithelial tumor of the jaw, comprising approximately $1\%$ of all tumors and cysts of odontogenic origin. The tumor has been the subject of much controversy and cliscussion. Amelobiastoma is slow growing, locally invasive, and has a high rate of total recurrence, but rarely metastasizes. This neoplasm has been considered radioresistant, so it has been treated with surgery primarily except some cases. Recently it is suggested that ameloblastoma is radiosensitive, so radiation therapy (RT) would be used in addition to or, in certain cases, in place of surgery. We report these two cases which were referred to the Department of Therapeutic Radiology for deciding tile need of postoperative RT, because amelobiastoma is rare and has been known tot be radioresistant. Postoperative RT was given to one of these two Patients.

Near-infrared imaging photometry supplemented by optical spectroscopy and narrow-band imaging of the H II region Sh 2-128 and its environment are presented. This region contains a developed H II region and the neighboring compact H II region S 128N associated with a pair of water maser sources. Midway between these, the core of a CO cloud is located. The principal ionizing source of Sh 2-128 is an 07 star close to its center. A new spectroscopic distance of 9.4 kpc is derived, very similar to the kinematic distance to the nebula. This implies a galactocentric distance of 13.5 kpc and z = 550 pc. The region is optically thin with abundances close to those predicted by galactocentric gradients. The $JHK_s$ images show that S 128N contains several infrared point sources and nebular emission knots with large near-infrared excesses. One of the three red Ks knots coincides with the compact H II region. A few of the infrared-excess objects are close to known mid- and far-infrared emission peaks. Star counts in J and $K_s$ show the presence of a small cluster of B-type stars, mainly associated with S 128N. The $JHK_s$ photometric properties together with the characteristics of the other objects in the vicinity suggest that Sh 2-128 and S 128N constitute a single complex formed from the same molecular cloud, with ages ${\~}10^6$ and < $3 {\times} 10^5$ years respectively. No molecular hydrogen emission was detected at 2.12 ${\mu}m$. The origin of this remote star forming region is an open problem.
