C. neoformans-associated cryptococcosis is primarily a disease of immunocompromised persons, has a world-wide distribution, and is often spread by pigeons in the urban environment. In contrast, C. gattii causes infection in normal hosts, has only been described in tropical and semi-tropical areas of the world, and has a unique niche in river gum Eucalyptus trees. Cryptococcosis is acquired through inhalation of the yeast propagules from the environment. C. gattii has been identified as the cause of an emerging infectious disease centered on Vancouver Island, British Columbia, Canada. No cases of C. gattii-disease were diagnosed prior to 1999; the current incidence rate is 36 cases per million population. A search was initiated in 2001 to find the ecological niche of this basidiomycetous yeast. C. gattii was found in the environment in treed areas of Vancouver Island. The highest percentage of colonized-tree clusters were found around central Vancouver Island, with decreasing rates of colonization to the north and south. Climate, soil and vegetation cover of this area, called the Coastal Douglas fir biogeoclimatic zone, is unique to British Columbia and Canada. The concentration of airborne C. gattii was highest in the dry summer months, and lowest during late fall, winter, and early spring, months which have heavy rainfall. The study of the emerging colonization of this organism and subsequent cases of environmentally acquired disease will be informative in planning public health management of new routes of exposure to exotic agents in areas impacted by changing climate and land use patterns.

The purpose of this study is to examine the motive of participating in the care work, the overall cognition survey for the care work and the infant care practice areas required in the care work for the child care helpers who activate in the care work, and search for methods of specializing infant care and care experiences on the results. Results of study showed that firstly, middle- or the late middle-age women participated in the care worker recognized care work as productive labor to create economic value and that secondly, the child care helpers' recognition degree of self-development and job satisfaction through performance of care work was wholly high level and that there was will of participation in training for self-development but actual participation rate was low due to restrictions by general conditions. Thirdly, the infant care practice areas and their particular contents that the child care helpers recognized in the care work necessary were highly shown in the whole. The requested level of education for safety management, play guidance, humanity guidance for infant and child was high. Point to discuss is that occupation stability and occupation image must be raised through the public job-hunting system for the child care helpers. In addition, a tailor-made education support suitable for the child care helpers' career stage is needed. Education support by the performance of infant care practice area and the educational requirements must be provided to major rearers to ensure that they can function as behavioral and emotional supporters. Finally, a support system for continuous self-management.

Background: In South Korea, African swine fever virus (ASFV) has spread among wild boars through Gangwon-do to Dangyang-gun, Chungcheongbuk-do on the southern border of Gangwon-do. To prevent the spread of ASFV to African swine fever (ASF)-free areas, it is necessary to identify areas with a high probability of finding ASFV-infected carcasses and to reduce the density of wild boars in those areas. In this study, we described the propagation trend of ASFV among wild boars, constructed the habitat suitability maps for ASFV-infected carcasses, and suggested areas with a high probability of finding ASFV-infected carcasses and an important route of ASFV transmission. Results: Despite the active quarantine policies in Korea to prevent the spread of ASFV through wild boars, there was no significant difference in the monthly average of number of ASFV-infected carcasses observed between 2020 and 2021. The ASFV-infected carcasses were found more in winter and spring (January to April). Since the first ASF outbreak in wild boars on October 2, 2019, the maximum width of ASFV-infected carcass distribution area was 222.7 km for about 26 months till November 20, 2021. The habitat suitability map, based on GPS coordinates of ASFV-infected wild boar carcasses, shows that highly detectable areas of ASFV-infected carcasses were sporadically dispersed in western and southwestern parts of Gangwon-do, and ranged from north to south of the province along the Baekdudaegan Mountains, whereas poorly detectable areas ranged along the north to the south in the middle parts of the province. Conclusions: Our suitability model, based on the GPS coordinates of ASFV-infected carcasses, identifies potential habitats where ASFV-infected carcasses are likely to be found and ponential routes where ASFV is likely to spread. Among ASF-free areas, the areas with high suitability predicted in this study should be given priority as survey areas to find ASFV-infected carcasses and hunting areas to reduce wild boar populations.

National park is one of the important types of protected area management systems established by IUCN and a management model for effective conservation and sustainable use of natural and cultural heritage in countries around the world, and it assumes important roles in conservation, scientific research, education, recreation and driving community development. This study takes Liaohe National Park in China, a typical representative of global coastal wetlands, as a case study, and uses python technology to collect travelogues and reviews of visitors from Mafengwo.com, Ctrip.com, Go.com, Meituan.com and Dianping.com as a source, and the text spans from 2015 to 2022. The results show that wildlife resources, natural landscape with river and sea, wetland ecology and fishing and hunting culture of northern China are fully reflected in the perceptions of visitors to Liaohe National Park. However, there is still much room for improvement in terms of supporting services and facilities, public education and tourists' experience and participation in Liaohe National Park. In this paper, we use python data visualization technology to study the public perception of wetland wildlife as the theme, and grasp the satisfaction, spatial distribution, activity content and emotional tendency of the public in the process of wetland wildlife as the theme, so as to better promote the Liaohe National Park to better carry out the public experience while strictly adhering to ecological protection, and to provide the Liaohe National Park with a better opportunity to This will provide scientific basis for the Liaohe National Park to play a better role in ecological civilization construction and education of ecological civilization awareness.

There have been groves, in many cases, along with hedgerows and remnant forests around a traditional Korean village. A village grove is very closely connected to the life of residents. Sometimes it was a holy place where important village festivals were held, and became a resting place for farmers, especially in sunny summer. As a matter of fact, it is noted that traditional Korean village groves had been fostered for many purpose as religion, Confucianism, scenery, sanitation, traffic guard, public security, agriculture, hunting, and military and public uses were included in Chosun Govemor General(1938). Village groves were usually located at the outlet of watershed inside which a village was built. In addition, village groves used to be established along part of mountain ranges, streams and streets. A unique type of village grove, called bibosoop was fostered especially where the outlet of watershed was largely opened. In other cases, it was placed where a part of mountain range was relatively low, or where village residents were likely to see ugly objects such as a huge cliff, stony upland with an unvegetated area and the like(Kim and Jang 1994). In a sense, a sheltebelt is a sort of bibosoop as it is a landscape element to complement places that are exposed to strong winds. However, it is comparable to other typical bibosoop that is situated at a topographically very specific zone of watershed. In this paper, we will address potential functions of Korean village groves from a perspective of modern landscape ecology and show current status of some remnants, based on preliminary surveys. A village grove functions as barrier or filter of objects such as water, nutrients, and other elements and habitat of wildlife (park et al. 2003, Lee 2004). The village grove slows down the flow of water and air, maintains soil moisture an hinders soil erosion, enabling cultivation of crops and bringing up creatures nearby. It contributes to enhancing biodiversity. Birds rest on shrubby and woody trees of the element. Presumably, other organisms may also inhabit the village groves and take advantage of it when those move from a forest patch to others. Emerging insects acclimate themselves in the shade of the green space before they fly to sunny air. Besides the village grove acts as a component of agroforestry system as leaf litter is shed from a grove to an asjacent agricultural area, and transformed into green manure(Lee 2004). By the way, many of the landscape elements were destroyed or declined in Koea during the past several decades. The losses have been parallel or linked to environmental degradation. Unfortunately, we have a little reliable data as for how many groves have disappeared in Korea until now. There has been no complete census on the village groves in Korea, and the viewpoints of survey were to a degree different depending on surveyors. So, it is difficult to analyze the temporal and spatial change of village groves. Currently, national inventory data of Korean village groves are available in three reports. We reviewed the locations of village groves and arranged those according to the present administrative units, DONG. With the limited data, we found that at least 484 of village groves were recorded in South Korea. Among all provinces, village groves were most in Gyeongsanbuk-Do Province and least in Chungcheongbuk-Do Province(Table 1). This is a preliminary report prepared while some quantitative data regarding functions and lossers of the village groves are being collected. More detailed data will be introduced in the near future.

Koh(袴) was a type of dress worn on the lower part of the body which was commonly used in the Northeast Asia. It was originally used by the Northern race for the need of nomadism or hunting. The origin of the Koh which appeared in the area would be found from the trousers of the Huns who influenced in the Northeast Asia, and became in the part of the Scythian culture. The Scythians are the nomadizing race inhabited in the Northern Caucasas on the wast of the Black Sea and influenced on the inland Eurasian steppe as the first typical horse-riding race. The objectives of Koh which had been worn in the Scythian, Mongolia, Korea as well as Japan as a part of Dongho dress and ornaments and to contemplate the transmission process by cultural exchange among different races for the period from 4th century to 7th century. 1. The Origination of the Koh The Koh was originated by the environmental factor to protect the cold in the North but also from the heat in the South, and was changed and developed as gradually satisfying to the needs of the times. In the Northeast Asia the Koh was in the class of the Northern Chinese garment, and was used widely by the horse riding Scythians who moved widely from the Eurasian inland to Japan. The oldest original which could reflect the type of the Northern clothes was a pair of trousers discovered in the Huns remains of Noin Ula. This showed the exact form of hunting clothes and had a similar form with the Korean female tro-users. Since the same form of trousers drawn on the wall painting of which was excavated 4-5th century ancient Koguryo(高句麗) tomb was the same form the trousers of Noin Ula seemed to be the original form of Koh in the Northeast Asia. 2. The Chinese Trousers It was the time of the King Mooryung(武靈王) in the Cho(趙) Dynasty B.C. 3th century that the trousers used regularly in China. However, the Koh had been used as undergarment which functioned for the protection of the cold not the horseriding garment. The trousers seemed to be not very obviously shown off since the Poh (袍) was long, but mainly used by the people from lower class. As people learned the adapted the trousers. It was essential for the times of war and quarrel. The king himself started wearing the Koh. The Chinese trousers were influenced by the Huns, the Northern clothes of the Scythian culture, and similar to the Korean clothes. 3. The Korean Trousers Korean was a race bared from the Eastern foreign group. It was obvious that the clothes was Baji-Jeogori(바지 저고리), the garment of the Northern people. This had the same form of the Scythian dress and ornaments which was excavated from the Mongolian Noin Ula. The Scythian dress and ornaments were influenced from the Ancient West Asia Empire and transmitted to the Northeast Koguryu by the horseriding Scythian. The trousers were kept in the traditional style by the common people in Korea were transmitted to Japan which were for behind in cultural aspect, as well as got used to the Chinese as the efficient clothes though active cultural exchange. 4. The Japanese Trousers The ancient Japanese clothes were influenced by the Southern factor but not the form of the Koh. As the Korean people group was moving towards Japan and conquer the Japanese in the 4-5th century, however, North Altaic culture was formed and at the same time the clothes were also developed. The most influenced clothes at this time were those of Baekge(百濟) and the trousers form called Euigon became the main form. Because of the climatic regional factor, it was tied not at the ankle but under the knee. From the view the ancient Japanese clothes disappeard about that time, it could be due to the conquest of the culturally superior race but not the transmission of the culture. In the latest 7th century both the Chinese and Japanese dress forms were present, but the Dongho(東胡) dress and its ornament from Korea was still the basic of the Japanese dress form.

This study is based on the official Chinese history of the ancient Korean(中國正史朝鮮傳) clothing and ornaments, and also tries to discover, study, and adjust the system of the ancient Korean clothing and ornaments. Ancient Korea has very poor official records of its clothing and ornaments. Therefore, this study had no choice but to rely on the official Chinese history to cover for the lack of resources. The official Chinese history documents are not only important for studying ancient Korean history, but also important for studying about the ancient Korean clothing and ornaments. This research selected historical documents about the ancient Korean clothing and ornaments from fifteen different Chinese dynasties' official documents, and then systematically classified the documents in order to compare them. All these processes confirmed the following subjects. In regards to the Kwan(冠: general hat), the hat types included Check, Byun(弁), Jeol-poong(折風), Jowoo-Kwan(鳥羽冠), So-gol(蘇骨), and Na-kwan(羅冠). These Kwan(冠) were influenced from Chinese clothing and ornaments. Gold and silver decorations on the Kwan(冠) were influenced from the Scythai culture. The feather decorations on the hat were residual of the bird worshiping culture or the hunting lifestyle. These things show that the ancient Korean clothing and ornaments originated the clothing and ornaments from the North. But the use of Jo-woo(bird feather) was common around the globe in many ways during the ancient times, regardless of area and period. The official Chinese history describes men's hair style as Choo-gyul (椎結) or sometimes pronounced, Choo-gyul(椎結). These seem to describe the topknot. Women had various types of hair styles such as Yu-byun-bal-su-hu (wear women's hair in a braid). The official Chinese history show that the ancient Korean clothing and ornaments originated the clothing and ornaments from the north. The ancient Korean clothing and ornaments influenced and were influenced by its neighboring countries.

The Kunang cave paleolithic site is located at Tanyang [$N37^{\circ}2'$, $128^{\circ}21'E$], Chungbuk Province, which is in the Central part of the Korean peninsula. The cave is developed at 312 amsl in a karstic mountainous area. The South Han River flows across this region and other caves can also be found near the river. The site was discovered in 1986 and excavated 3 times by the Chungbuk National University Museum until now. The cave was wellpreserved from modem human activities until the first discovery. The full length of the cave is estimated to be ca. 140 m. However, a spacious part up to 11 m from the entrance has been excavated. Eight lithological units are divided over the vertical profile at a depth of 5 m. Each unit is deposited in ascending order as follow: mud layer (Unit 9), lower complex (Unit 8) which is composed of angular blocks and fragments with a muddy matrix, lower travertine layer (Unit 7； flowstone), middle complex (Unit 6; cultural layer) which is composed of fragments with a muddy matrix, middle travertine layer (Unit 5； flowstone), yellowish muddy layer (Unit 4), upper complex (Unit 3； cultural layer) which has a similar composition to Unit 8. the upper travertine layer (Unit 2； flowstone), and finally surface soil layer (Unit 1). The most abundant vestiges in the cultural layers are the animal bones. They are small fractured pieces and mostly less than 3 cm in length. About 3,800 bone pieces from 25 animal species have been collected so far, 90 percent of them belonging to young deers. Previous archaeological study of these bone pieces shows thatprehistoric people occupied the cavenot for permanent dwelling but for temporary shelter during their seasonal hunting activity. More extensive studies of these bones together with pollen analysis are in progress to reconstruct the paleoenvironment of this cave. Only a single date (12,500 BP) obtained from a U-Th measurement of the upper travertine layer was previously available. In spite of the importance of the cave stratigraphy, there was no detail chronological investigation to establish the depositional process of the cultural layers and to understand the periodic structure of the cave strata, alternating travertine floor and complex layers. We have measured five 14C age dating (38900+/-1000, 36400+/-900, 40600+/-1600, more than 51000 and 52000 14C BP) using Seoul National University 14C AMS facility, conducted systematic process of the collagen extraction from bone fragments samples. From the result, we estimate that sedimentation rate of the cave earth is constant, and that the travertine layers, Unit 2 and Unit 3, was formed during MIS 5a(ca. 80 kBP) and MIS 5c (ca. 100 kBP) respectively. The Kunang Cave site is located at Yochonli of the region of Danyang in the mid-eastern part of Korea. This region is compased of limestones in which many caves were found and the Nam-han river flows meanderingly. The excavations were carried out three times in 1986, 1988, and 1998.

최근 국내 멧돼지 문제는 농작물 피해 및 도심 출몰로 인하여 사회적으로 심각한 상황에 직면해 있다. 본 연구는 경남 거창군의 멧돼지에 의한 농작물 피해사례를 바탕으로 피해에 영향을 끼치는 환경 요인들에 대하여 파악하고자 2012년 5월부터 10월까지 수행 되었다. 농작물 피해 분석 결과 주로 8월과 9월 사이 피해가 가장 많이 발생하였고, 벼의 빈도가 가장 높았으며 피해 강도는 고구마가 가장 높은 것으로 나타났다. 이는 멧돼지의 농작물 선호성과 특정시기에 대한 가용성과 관련이 있는 것으로 판단된다. 또한 농작물 피해에 경사, 지형기복, 산림과의 거리, 수계로부터의 거리, 도로로부터의 거리, 주거지로부터의 거리의 요인들이 영향을 미치는 것으로 나타났다. 피해 강도에 따른 환경요인의 차이는 나타지 않아 멧돼지는 한번 피해를 끼친 농경지를 지속적으로 방문하여 피해를 누적 시키는 것으로 파악된다. 따라서 멧돼지에 의한 농작물 피해를 저감시키기 위해서는 피해가 발생할 수 있는 곳에 멧돼지가 비선호하는 작물로 대체 재배하며 전기펜스 설치, 엽사와 포획틀을 이용한 멧돼지 개체수 조절이 필요할 것으로 판단된다.
