The supply of high quality filling materials for pavement base course or reclamation is getting harder. So, there is an attempt to use soft mudstones as an earth filling material in Pohang area. But the engineering properties of the soil deposit placed with soft mudstones have not been clearly evaluated yet. We investigated the water absorption and softening, the slaking behavior and the geological mechanism in order to obtain an effective way of estimating the magnitude of land subsidence and the reduction of soil strength. The applicability of soft mudstones is examined by a variety of laboratory tests and pilot-scale field tests. In addition, it is necessary to consider the environmental characteristics of soft mudstones as a reclaiming material, Consequently, the results from the current study can be used to prevent any construction defects due to the careless use of soft mudstones for the pavement base course or reclamation.

Jo Jeongsan's religious activity undertaken to benefit society can be organized into two categories. First, attention can be paid to Jo Jeongsan's religious activity of establishing religious order by enshrining Kang Jeungsan as the God of Ninth Heaven and making the Great Dao of Heaven and Earth the basic idea inspiring the social activity of his order. This was completed through the 50 years of propagation work carried out by Jo Joengsan in accordance with Kang Jeungsa's purpose of saving the world and its inhabitants. Second, his practice of social work in the field of people's lives based on the idea of the Dao can also be observed. This religious activity of Jo Jeongsan which began in 1909 was the sacred manifestation of his will to realize Kang Jeungsan's purpose of saving the world and people, and it was also a practice of spreading virtue throughout the world. In addition, Park Wudang carried out Sihak and Sibeop Gongbu (two varieties of holy work) for the cultivation of Dao trainees, and those methods came from the systematic cultivation practice established by Jo Jeongsan. Regarding this, we can refer to Kang Jeungsan's saying, "As the Dao shall dwell in the 12,000 peaks of Geumgang Mountain, the same number of sages who were enlightened to the Dao will be born into the world." The perfected state of human maturity or the emergence of people who are enlightened to the Dao would be the completion of the idea of saving the world and its inhabitants. Therefore, the holy works of Sihak and Sibeop that are now being carried out can be seen as the continuance of the pursuit of saving the world and humankind, as it was continually upheld by Park Wudang's predecessors, Jo Jeongsan and Kang Jeungsan.

Zou Si Cong is a very significant female artist from the period when China was forming its modern arts and culture. Zou Si Cong, who was influenced by China's political and social upheaval, was born in 1939 and died in 1996. Her actual work period was after China's 'Cultural Revolution' and lasted only 13 years, from 1978 to 1990. Her passion for art never stopped, even when she was suffering from severe arthritis with its torturing pain. There were big changes that occurred in her work; 'Early Work', 'Realistic Work', 'Mine Worker Painting', 'Yi Tribe' Painting', 'Lotus Paintings'. 'Mine Worker Painting', which represented a new figure by abandoning traditional techniques, dividing picture space, and changing and distorting forms, was the one that had the greatest impact of all on a lot of people and strongly influenced modern Chinese figurative painting. The characteristics of Zou Si Cong's work are in its 'Traditionalism', 'Realism, and 'Historical' aspects. Zou Si Cong developed her uniqueness, along with Western expressions, based on traditional Chinese painting techniques. Realism, through realistic rendering, appeared in her figurative paintings during the Cultural Revolution Period. 'Yi Tribe' paintings lively illustrated their lives. She creatively reinterpreted history in the composition of Mine Workers, which is based on the historical record of Chinese barbarity.

The zinc-lead deposits at the Yeonhwa I mine were investigated in terms of ore-forming geologic setting, structural style of ore control, geometry of individual orebodies, zoning, paragenesis and chemical composition of skarn minerals, as well as metal grades and ratios of selected orebodies. The Yeonhwa I mine is characterized by a large swarm of chimney type massive orebodies with thin skarn envelopes, boldly developed through a thick sequence of Pungchon Limestone, the overlying Hwajeol Formation, and the underlying Myobong Slate of Cambrian age. Nearly 20 orebodies of similar shape, but of varying size are arranged in a V-shaped pattern with northwest and northeast trends, clearly indicating an outstanding ore control by a conjugate system of fractures with these trends. Important orebodies are the Wolam 1, 2, 3, and 5 orebodies in the west, and the Namsan 1, 2, 3. and 5 orebodies in the east, among others. The Wolam 1 orebody, which was observed from the -360 level through the -240, -120, and 0 levels to the surface outcrops (totaling a vertical height of about 500m), shows a vertical variation in skarn mineralogy, ranging from pyroxene-garnet zone on the lower levels. through pyroxene (without garnet) zone on the intermediate levels, and finally to rhodochrosite vein on the upper levels and surface. Microprobe analyses of pyroxene and garnet on a total of 14 mineral grains revealed that pyroxenes are manganoan salitic in most samples, with downward increase of Fe and Mn, whereas garnets are highly andraditic, containing fractions of subordinate grossular with downward decrease of Fe. This indicates a reverse relationship of Fe-contents between pyroxene and garnet with depth. Ore minerals are major sphalerite, subordinate galena, and minor chalcopyrite. Sulfide gangue minerals include major pyrrhotite, and minor pyrite and marcasite of later age. Two types of variational trends in metal grades and ratios with depth are present on the plots of assay data from the Wolam orebodies: one is a steady upward increase in Pb, Zn, and Pb:Zn ratios, with a terminal decline at the top of orebody: the other is an irregular or sinusoidal change. The former is characteristic of chimney-type orebodies, whereas the latter is of vein· shaped orebodies. The Pb grades show large variations among orebodies and from level to level, whereas the Zn grades are relatively constand or less variable.

The origin of Korean mime is traceable to sacred actions of prehistoric age. There are materials about mime of this age in the archeological materials of this age, oral literature/myth, and written literature about this age. There were traces of the most original form of mime in primitive ritual of tribal nation age. The mimes of Samkooksidae/Tree Nation Age of Korea were presented to forms of Kamoobekhee(歌舞百戱)/Sanakbekhee(散樂百戱). We can discover traces of mime of this age in Hosunmoo(胡旋舞), Gwangsumoo(廣袖舞), Kweraehee(傀儡戱), Keeak(伎樂), Kummoo(劍舞) Muaemoo(無㝵舞), and so forth. Especially, Keeak in Beckjae was mask mime of Buddhistic contents. We can recognize that secular theatres were more diversified and strengthened than sacred thaetres in Nambukgooksidae/South-north Nation Age. According to these changes, there were many changes in the mime of this age. We can concretely find traditions of mime of this age in Cheryongkamoo(處容歌舞), Hwangchanmoo(黃倡舞), Taemyun(大面), Wuljen(月顚), Sodok(束毒)', Sanyae (狻猊), and so forth. Mimes of Koreasidae/Korea Age take diverse forms of puppet play, mask play, dance play. Established traditional mimes as Cheryongkamoo(處容歌舞) were widely disseminated in society. And dance plays of mime form as Hunsundo(獻仙桃), Pokurak(抛毬樂), Yunhwadae(蓮花臺)' were imported from Song Nation of China. Mime of Chosundidae/Chosun Age were developed with changes of theatre that were divided into Kyusickjeehee[規式之戲] as Kwangdae(廣大), Ser-in(西人), Joojil(注叱), Rongryung(弄鈴), Kendoo(斤頭) and Sohakjihee[笑謔之戱] as Soochuk(水尺) Sengkwangdae(僧廣大). Styles of theatre in this age were specialized into mudangkuk, Pungmoolkut, Inhyunguk/Puppet play, Talnoree/Mask paly, Pansori, Kungjoong Kamuakguk. According to this changes, mime of this age were specialized into diverse aspects. Korean mime were specialized into Kutnorum-formed mime, Inhyungnorum-formed mime, Jabsaeknorum-formed mime, Talnorum-formed mime, Kungjoongmuyong-formed mime, Pansori-formed mime, and so forth.

Algal blooms not only destroy fish habitats but also diminish biological diversity of ecosystem which results into water quality deterioration of 4 major rivers in South Korea. The relationship between algal bloom and environmental factors had been analyzed through the cross-correlation function between concentration of chlorophyll a and other environmental factors. However, time series of cross-correlations can be affected by the stochastic structure such auto-correlated feature of other controllers. In order to remove external effect in the correlation analysis, the pre-whitening procedure was implemented into the cross correlation analysis. The modeling process is consisted of a series of procedure (e.g., model identification, parameter estimation, and diagnostic checking of selected models). This study provides the exclusive correlation relationship between algae concentration and other environmental factors. The difference between the conventional correlation using raw data and that of pre-whitened series was discussed. The process implemented in this paper is useful not only to identify exclusive environmental variables to model Chl-a concentration but also in further extensive application to configure causality in the environment.

Packaging bags and corrugated boxes prepared from newly developed antimicrobial packaging paper had greater ability to prolong freshness of packed fruits, and lower weight loss of fruits and microbial growth than non-treated bags and boxes. Addition of zeolite to paper greatly increased absorbance of aging hormone, $C_{2}H_{4}$, emitted from stored fruits, and contributed to decrease in putrefied fruits during storage. Water repellent agent such as alkyl ketone dimer played significant role in preventing functional paper from absorbing water from stored fruits, leading to preservation of fresh weight in stored fruits. Because rise in production cost of functional packaging paper could be offset by reduction of fruit and vegetable wastes, storing fruits and vegetables in functional paper containers was more economical than storing in non-treated containers.

We have recently experienced a case of decannulation difficulty resulted from head and thoracic injury. The patient was 21-year-old male who undergone craniectomy and tracheotomy at other hospital about 7 months ago prior to admission On admission, there was swelling in glottic and subglottic region in indirect laryngoscopy and bronchoscopy with fixation of vocal cords in paramedian position. We tried to reestablish an adequate air way with bougination using Jackson esophageal bougie but there was no effect with it. So we performed vertical incision through cricoid cartilage and tracheal rings and insertion of Teflon tube in stenotic lesion for 9 months and removed it. At present time, the patient has been satisfactory corking training course.

Recently, the depth of tunnel constructed is getting deeper, which increases difficulty in construction works. Deliberate tunneling techniques are needed as the span and length of tunnels are increased. As one of the technical developments for tunnel, U-shaped and reinforced spider lattice girders are developed by optimizing the spider used in 95mm lattice girder as tunnel steel ribs. In order to evaluate the load bearing capacity of the lattice girder, the 4-point flexural tests are carried out. For the laboratory tests, straight specimens are made for the existing lattice girder and the new lattice girder. The results of the flexural tests showed that the maximum load bearing capacity of the new lattice girders was higher than the traditional one. The load-displacement behavior of the test specimens showed the elasto-plastic behavior in the existing lattice girder and the stress softening behavior in the new lattice girder. It was found that the load bearing capacities are changed depending on the location of the loading points.
