The forest canopy gap has been well known as a substantial process of forest cyclic regeneration and important role in stand structure, dynamics, and biodiversity of the forest ecosystem. Based on 3,600 $5m{\times}5m$ square grids in a 9ha permanent experimental plot, the study was conducted to evaluate the regeneration pattern of woody species by developmental stage {seedlings (<1 m of height), saplingI (>1 m of height, <2 cm of DBH), and saplingII (2 cm$<200m^2$), $201-400m^2$, $400-600m^2$, $601-800m^2$, and $>800m^2$) in the mixed broadleaved-Korean pine forest. The results indicated that the regenerating trees of Populus ussuriensis occurred only in the canopy gap area, considered to be a typical gap-dependent species. The regeneration of Ulmus japonica, Ulmus laciniata, and Maackia amurensis could be generally satisfied with the gap size of $201-600m^2$, Betula costata and Prunus padus with gap size of $401-800m^2$, Picea koraiensis with gap size of $201-800m^2$, Fraxinus mandshurica and Syringa reticulata var. mandshurica with smaller than $800m^2$, respectively. Acer ukurunduense and Acer tegmentosum were likely to have no problem with the gap size to make gap regeneration. Acer mono and Tilia amurensis looked more capable of regenerating in the closed canopy disregarding the upper crown condition. The regeneration of Pinus koraiensis and Abies nephrolepis had no trouble under the canopy condition in less than $800m^2$of gap size. The density of regenerating shrubs was rather high, especially under the closed canopy, considered to be associated with great amount of regeneration production in such shade tolerant species as Lonicera maackii, Corylus mandshurica, Euonymus pauciflorus, and Philadelphus schrenkii under the closed canopy. Pearson correlation coefficient was computed to compare the similarity among non-gap area and five gap size classes by developmental stages for trees and shrubs. The similarity coefficients among closed canopy and the gap size classes were mostly significantly correlated to each other with a few exceptions.

This study is made on the royal lady's dress In late Joseon dynasty according to the King Heon-jong and Lady Kyung-bin's Wedding Diary in the year of Jung-mi(1847) and summarised as follows: Girls' full dress was a set of a red skirt, a violet undo. jacket, and a light yellow jacket and a green Gyeon-ma-gi(a kind of top jacket) with he. hair Saeng-meo-ri hanging Do-tu-rak-daeng-gi(a kind of hair ribbon). At the big ceremony, girls wore a green Dang-ui instead of Gyeon-ma-gi. A girl picked up as a royal concubine wore a green Won-sam, which was decorated with gilt letters meaning longevity, patched emblems of gilt letter meaning longevity on the breast and on the back, belted with Bong-dae(a red sash with gilt phoenexes), like a princess's full dress. At the Kyung-bin's installation of Crown Princess and her first greeting ceremony with royal elders, she wore a green Won-sam as a formal dress, which had an embroidered emblem of phoenix, the belt with crystal ornaments, Pae-ok(佩玉), Kyu(圭) of blue jade, Shou(綬) with an phoenix. At a Dong-wrae-yun(drinking ceremony after bride and bridegroom's bowing to each other), she wore the embroidered red Jang-sam as a formal dress. Kyung-bin wore a purple Won-sam with Bong-dae as a full dress for a royal feast. According to the occasions, the same dress was differentiated with ornaments and rotors. Ji-keum-bal was an attire for ordinary ceremony. The attire was equipped with a woven gold green Dang-ui with an emblem of phoenix, a blue gilt underskirt and a red gilt overskirt. No-ui was worn as outdoor clothes. Jang-sam was worn by various classes, so it was differentiated with materials and names according to her class.

Yuan Shi Kai, the first President of the Republic of China, established a ceremonial uniform system based on ancient styles in 1914 just before the national polity was changed to the Empire of China in 1915. This system is Jisiguanfuzhi (a system on costumes for memorial services), and figures included in the system are Jisiguanfutu (figures showing costumes for memorial services). This study is the first to examine Jisiguanfuzhi and Jisiguanfutu and to approach the background idea of the establishment of the system with a focus on the meaning of 'unity.' Jisiguanfuzhi regulates the ceremonial uniform system of all classes from the President along with the 1st-class to the 5th-class people. The uniform consists of a crown, robe, belt, the mid-section cloth, and boots. In addition, the uniforms of ritual musicians and dancers are included. The basic principles in establishing the system were the restoration of ancient systems, the adoption of convenience, the acceptance of current practices, and the implication of symbolism. Jisiguanfuzhi clarifies that the pattern of the ceremonial uniforms was modeled on Juebianfu, for religious services. The reason for choosing Juebianfu for religious services was to achieve 'unity' and Juebianfu was associated with 'unity' because it was common to all, from the emperor to the gentlemen class, in ancient times. Yuan Shi Kai tried to show flexibility to the gentlemen class who represented the intellectuals at that time by adopting Juebianfu for religious services, fearing that the gentlemen class might oppose the attempt to restore the imperial system. Therefore, although Jisiguanfuzhi adopted mostly Mianfu and royal sacrificial robes, it also emphasized 'unity' by professing that the uniforms were based on Juebianfu for religious services.

The purpose of this study is to evaluate the risk of cropland and man-made infrastructures in a landslide-prone area using a GIS-based method. To achieve this goal, a landslide inventory map was prepared based on aerial photograph analysis as well as field observations. A total of 550 landslides have been counted in the entire study area. For model analysis and validation, extracted landslides were randomly selected and divided into two groups. The landslide causative factors such as slope, aspect, curvature, topographic wetness index, elevation, forest type, forest crown density, geology, land-use, soil drainage, and soil texture were used in the analysis. Moreover, to identify the correlation between landslides and causative factors, pixels were divided into several classes and frequency ratio was also extracted. A landslide susceptibility map was constructed using a bayesian predictive model (BPM) based on the entire events. In the cross validation process, the landslide susceptibility map as well as observation data were plotted with a receiver operating characteristic (ROC) curve then the area under the curve (AUC) was calculated and tried to extract a success rate curve. The results showed that, the BPM produced 85.8% accuracy. We believed that the model was acceptable for the landslide susceptibility analysis of the study area. In addition, for risk assessment, monetary value (local) and vulnerability scale were added for each social thematic data layers, which were then converted into US dollar considering landslide occurrence time. Moreover, the total number of the study area pixels and predictive landslide affected pixels were considered for making a probability table. Matching with the affected number, 5,000 landslide pixels were assumed to run for final calculation. Based on the result, cropland showed the estimated total risk as US $ 35.4 million and man-made infrastructure risk amounted to US $ 39.3 million.

The purpose of this study is to identify the quality of landslide susceptibility in a landslide-prone area (Jinbu-myeon, Gangwon-do, South Korea) by spatial prediction modeling approach and compare the results obtained. For this goal, a landslide inventory map was prepared mainly based on past historical information and aerial photographs analysis (Daum Map, 2008), as well as some field observation. Altogether, 550 landslides were counted at the whole study area. Among them, 182 landslides are debris flow and each group of landslides was constructed in the inventory map separately. Then, the landslide inventory was randomly selected through Excel; 50% landslide was used for model analysis and the remaining 50% was used for validation purpose. Total 12 contributing factors, such as slope, aspect, curvature, topographic wetness index (TWI), elevation, forest type, forest timber diameter, forest crown density, geology, landuse, soil depth, and soil drainage were used in the analysis. Moreover, to find out the co-relation between landslide causative factors and incidents landslide, pixels were divided into several classes and frequency ratio for individual class was extracted. Eventually, six landslide susceptibility maps were constructed using the Bayesian Predictive Discriminant (BPD), Empirical Likelihood Ratio (ELR), and Linear Regression Method (LRM) models based on different category dada. Finally, in the cross validation process, landslide susceptibility map was plotted with a receiver operating characteristic (ROC) curve and calculated the area under the curve (AUC) and tried to extract success rate curve. The result showed that Bayesian, likelihood and linear models were of 85.52%, 85.23%, and 83.49% accuracy respectively for total data. Subsequently, in the category of debris flow landslide, results are little better compare with total data and its contained 86.33%, 85.53% and 84.17% accuracy. It means all three models were reasonable methods for landslide susceptibility analysis. The models have proved to produce reliable predictions for regional spatial planning or land-use planning.

This paper deals with risk assessment of life in a landslide-prone area by a GIS-based modeling method. Landslide susceptibility maps can provide a probability of landslide prone areas to mitigate or proper control this problems and to take any development plan and disaster management. A landslide inventory map of the study area was prepared based on past historical information and aerial photography analysis. A total of 550 landslides have been counted at the whole study area. The extracted landslides were randomly selected and divided into two different groups, 50% of the landslides were used for model calibration and the other were used for validation purpose. Eleven causative factors (continuous and thematic) such as slope, aspect, curvature, topographic wetness index, elevation, forest type, forest crown density, geology, land-use, soil drainage, and soil texture were used in hazard analysis. The correlation between landslides and these factors, pixels were divided into several classes and frequency ratio was also extracted. Eventually, a landslide susceptibility map was constructed using a logistic regression model based on entire events. Moreover, the landslide susceptibility map was plotted with a receiver operating characteristic (ROC) curve and calculated the area under the curve (AUC) and tried to extract a success rate curve. Based on the results, logistic regression produced an 85.18% accuracy, so we believed that the model was reliable and acceptable for the landslide susceptibility analysis on the study area. In addition, for risk assessment, vulnerability scale were added for social thematic data layer. The study area predictive landslide affected pixels 2,000 and 5,000 were also calculated for making a probability table. In final calculation, the 2,000 predictive landslide affected pixels were assumed to run. The total population causalities were estimated as 7.75 person that was relatively close to the actual number published in Korean Annual Disaster Report, 2006.

1. After the Chu Dynasty(周代), we can confirm the fish shape mark made of stones as the relics of the Chunkuk dynasty(戰國時代). In the Shu Dynasty(隋代), the system of bamboo and the rabbit shape mark made of silver into the fish shape mark. As it were, made of bamboo or siltier changed into the fish shape mark made of jade, gold, silver or wood. 2. In the Dang Dynasty(唐代), the used the fish shape credit mark made of jade, gold, silver, copper or textile, according to their classes. According to one's posit the man who wore purple, red coat, credit mark made a gold and silver. attached with putting them in fish bags. 3. In the Ryo Dynasty(遼代), there was also a system of attaching marks. The emperor was hanging the fish shape and the officials attached the double fish shape to the common dress. fish shape of jade. gold, amber, agate, silver or copper. without any fish bag. 4. The Song Dynasty(宋代) followed the system of the Dang Dynasty they used only the fish shape bags without marks in them. Hanging the fish shape bags made of gold and silver at the back side of the belt. 5. The Gin Dynasty(金代) carried out the system of made jade, gold or silver like the Dang, Song and Ryo Dynasty. In the Sejong Kingdom a system of paper card was carried out as the credit mark of the eighth and the ninth grade. 6. In the Ming Dynasty(明代), the military official general attached the golden, silver, ivory of jade, wood and copper cards with their positions and names. 7. Following the Dang Dynasty, Japan made of fish shape bags to their clothes. Colors of their fish shape marks were same as their clothes. They made the marks, such as crystal, cow's horn, lead and nickel and plated them with gold or silver. 8. In Korea, Pohai(발해) established the fish shape credit mark differed in material. gold, silver or copper according to their positions. We can confirm the Unified Silla(南國;統一新羅), carried out the system of attaching the fish shape in Chonma Chong(천마총), Golden Crown Chong(金冠塚), the King's 13-17 belt ring unearthed at the north part of Court South threat Chong(황남대총), the fish shape golden or silver, to their purple or red ceremonial coats. In the Koryo Dynasty(高麗), like the Dang, Song and Pohai, they attached the fish shape golden or silver marks, to their purple or red ceremonial coats.

치내치는 치아 조직이 석회화되기 전에 법랑기가 치유두 내로 함입되어 형성된 발육성 기형이다. 가장 널리 통용되는 치내치의 분류법은 방사선 사진 상에서 함입(invagination)이 얼마나 치관에서 치근 쪽으로 연장되어 있는지에 따라 분류하는 Oehler's classification system이다. 그 중 Oehler's classification type III는 함입이 치근까지 연장되어 치주인대와 직접적으로 'pseudo foramen'을 통해 교통하는 경우를 말하며 대체로 치수와는 독립적으로 존재한다. Type III 함입을 통한 감염은 언제나 치주조직의 염증성 반응을 야기할 가능성이 있으며, 이처럼 'pseudo foramen' 주위로 염증성 병변이 발생한 경우 이를 'peri-invagination periodontitis'라 한다. 본 증례는 Oehler's type III 치내치를 갖는 상악 측절치의 'peri-invagination periodontitis'을 주소로 내원한 두 환자에게 각각 다른 치료적 접근을 통하여 양호한 결과를 얻었다. 치내치에 대한 처치 시 조기 진단과 예방적 치료를 통한 치수의 건강 유지가 매우 중요하나, 이미 치수까지 질환에 이환 되었을 경우 환아의 나이, 치근 성숙도, 함입의 종류, 염증의 치수 이환 여부 등을 고려하여 치료계획을 수립해야 한다.
