Korean Landscape Garden may be described according to its stage of development. In the primitive agricultural era, the garden was preceded by vegetable yards and at this time rock arranging (Soo-Sok garden) was initiated together with the megalithis culture of dolmens, heavenly altars and tumuli. In the early Three Kingdom period palace gardens were built on a grand scale and toward the end of fourth century temple garden were introduced along with Buddhism. These gardens evolved to the flourishment of "HWAGE"(terraced gardens) rock arrangements of ZEN, early KOR-YO period. Especially since the middle of KOR-Yo period the "IM-CHUN"(forest and pond) garden became popular, while during Cho-Son period "HWAGE" in the back yard, pond and pool garden and "IM-CHUN" style country villa became fashionable. The Korea traditional Landscape garde may be characterized that first it is a nature Landscape style, which makes the maximum accomodation with the surrounding nature. Secondly, the Korean garden is built creatively by utilizing the elements of its climate and topography, Kogu-Ryo, Paik-Je great-Kaya and Sil-Ra had developed original a castle town plans and beautiful gardens rock arrangements which precede the equivalent style of China and set the prototype for Japan. The Landscape art of waterfalls and rock arrangements at An-Ap-Chi garden of 7th century has no equals in China and set the origin of pond style of Japanese garden.

By the progress of genome sequencing, infrastructures for marker-assisted breeding (MAB) of rice came to be established. Fine mapping and gene isolation have been conducted using the breeding materials derived from natural variations and artificial mutants. Such genetic analysis by the genome-wide dense markers provided us the knowledge about the many genes controlling important traits. We identified several genes or quantitative trait loci (QTL) for heading date, blast resistance, eating quality, high-temperature stress tolerance, and so on. NILs of each gene controlling heading date contribute to elongate the rice harvest period. Determination of precise gene location of blast resistance gene pi21, allowed us to overcome linkage drag, co-introduction of undesirable eating quality. We could also breed the first practical rice cultivar in Japan with a brown planthopper resistance gene bph11 in the genetic back-ground of an elite cultivar. Discovery of major and minor QTLs for good eating quality allowed us to fine-tune of eating quality according to the rice planting area or usage of rice grain. Many rice cultivars have bred efficiently by MAB for several traits, or by marker-assisted backcross breeding through chromosome segment substitution lines (CSSLs) using genetically diverse accessions. We are also systematically supporting the crop breeding of other sectors by MAB or by providing resources such as CSSLs. It is possible to pyramid many genes for important traits by using MAB, but is still difficult to improve the yielding ability. We are performing a Genomic Selection (GS) for improvement of rice biomass and grain yield. We are also trying to apply the genome editing technology for high yield rice breeding.

Aerosol measurements were carried out at Kosan, Cheju Island, Korea for the period from July 20 to August 10, 1994. Total suspended particles were collected by high volume samplers and PM 2.5 particles with gaseous volatile species were collected by a filter pack sampler and their ionic composition are analyzed. The average mass concentration of PM 2.5 particles was comparable to that of PM 3 particles collected during March, 1994 at the same site but the average non sea-salt sulfate concentration was higher that that of PM 3 particles, implying the fraction of anthropogenic air apllutants during this period is higher than that during March, 1994. During the measurement period, two distincitive patterns were observed, high concentrations of mass and water soluble ions were observed between July 20 and August 1 while those during after August 2 were low. Back trajectory analysis results show that air masses arriving at Kosan during the earlier period were mainly from Korea and Japan while those during the later period were from the North Pacific Ocean. It is suggested that the particle ion concentrations during the later period are marine background concentrations at Kosan during the summertime.

It has passed 20 years since the first conference of the Korean Psychosomatic Society(KPMS) had been held. Therefore, it seems that it is the appropriate time to evaluate the current status and to look back the history of the Korean psychosomatic medicine in three aspects, clinical treatment, education, and research, and to make a plan for the future. Of the three areas, the clinical practice of Korean psychosomatic medicine will be discussed. As the past, I reviewed the historical background and development of KPMS, and the proposals presented at the first conference of KPMS in 1992. As the present, I presented the short stories about the psychosomatic clinic in Japan, Germany, and USA, to compare it with the present status of Korean one. And finally I made careful proposals for the future of the Korean psychosomatic medicine.

This study aimed to provide data for establishment of resource management system of Iriomote Island in Okinawa Japan. Nature resource management system of Iriomote Island can be categorized into eight stages which are equivalent to regional development stages. 1) Networking among local people, tourists, researchers, tour operators and government authorities enhanced collection of resource data. 2) On the early stage, resource data were available only to researchers and government authorities. From the third stage of this system, however, local people were also involved in resource investigation, so they became to well recognize the values of their local resources. 3) On the sixth stage, data on unfamiliar local resources and attractions became to be known to people by real-time data collection and data provision services. The tourist number gradually increased and their visitation patterns were dispersed into different sites and seasons. In addition, some tourists also participated in resource investigation and they were likely to visit the place again. 4) To achieve successful ecotourism development, it is necessary to establish a management system with a feed-back process to identify, evaluate, use and protect the resources.

The objective of this study is to examine the prevalence of musculoskeletal disorders(MSDs) among nursing personnels. A self-reporting survey adapted from Nordic questionnaires was used as diagnostic tool, and conducted for 162 nurses working for a general hospital. The survey was performed five times every three months during a year. The MSDs were defined by using three criteria, depending upon the frequency, duration and pain intensity of the symptoms. The results showed that the 12-month prevalences of MSDs at any body site by criterion 1, 2, 3 were 56.8%, 53.7%, 45.7%, respectively, and that the shoulder was the most susceptible to MSDs, followed by knee/lower leg, lower back, hand/wrist, neck, ankle/feet, finger, etc. Only one statistically significant risk factor of departments or units was identified through the Chi-square test. The prevalence of MSDs was the highest in intensive care unit, second in surgical ward, while the prevalence was the lowest in emergency room. The MSDs prevalence of Korea at any body part or by body part was much lower than that of foreign countries such as Japan, USA, Sweden, etc. This implies that when considering poor working conditions and load in Korea, the incidence rate of MSDs may rapidly increase in Korea in the future.

We have been developing a method to build models for time series using Genetic Programming. The proposed method has been applied to various kinds of time series e.g. computer-generated chaos, natural phenomena, and financial market indices etc. Now we apply the prediction method to time histories of seismic ground motion i.e. one-step-ahead prediction of seismographic amplitude. Waves of earthquakes are composed of P-waves and S-waves. They propagate in different speeds and have different characteristics. It is believed that P-waves arrive firstly and S-waves arrive secondly. Simulations were performed based on real data of Hyuganada earthquake which broke out at southern part of Kyushuu Island in Japan. To our surprise, prediction model built using the earthquake waves in early time can enough precisely predict main huge waves in later time. Lots of experiments lead us to conclude that every slice of data involves P-wave and S-wave. The simulation results suggest the GP-based prediction method can be utilized in alarm systems or dispatch systems in an emergency.

While human error happens repeatedly in the semiconductor industry in Korea, which has brought a tremendous loss from manpower, welfare etc., there are limitations to human error prevention activities. When a semiconductor company introduces new machines and facilities from Japan or Germany, the companies often do not consider human factors in the design. Also, semiconductor companies are so occupied with promoting increased productivity, their attention to human errors has been pushed aside. Negative aspects of technical exchange associated with safety management are one aspect of the industry's nature. A semiconductor company recently began acknowledging on the back of TQM(Total Quality Management) that human error has a decisive effect on the safety. There are a number of uncontrollable and hard to handle event sets because the nature of these events with a human error may often be threatened or very intensive. It is strongly required that systemic studies should be performed to grasp the whole picture of a current situation for hazard factors. This study aims to examine the human error approach through the case of human error prevention field activities in a semiconductor industry compared with the activities and experience in nuclear power plants.

A series of thermotropic Polyurethanes mesogenic unit were synthesized by polyaddition of a para-type diisocyanate such as 2,5-tolylene diisocyanate(2,5-TDI) with 4-4'-bis($\omega$-hydroxyalkoxy) biphenls(BPm: $HOCmH_{2m}OC_{6}H_{4}OC_{m}H_{2m}OH$ : m is the carbon number of the hydroxyalkoxy group) in DMF. Intrinsic viscosities of the polymers were in the range of 0.41~0.99dL/g DSC thermograms for these polymers exhibited two endothermic peaks corresponding to phase transitions of melting and isotropization. For examplem polyurethane 2,5-TDI/BPll with [η]=0.99 prepared from 2.5-TDI and 4,4'-bis[11-hydroxyundecaoxy biphenyl(BP11) a liquid crystalline phase from 156 to 173$^{\circ}C$. The thermotropic properites of liquid crystalline polyurethanes have been investigated by wide-angle X-ray scatter(WAXS), infrared (IR) spectroscopy, and differential scanning calorimetry (DSC). The mesomorphic behavior of the polyurethanes was concluded to be greatly dependent on the intermolecular hydrogen bonds through the urethane.

In the 1960s of Korea, the normalization of diplomatic relations between Korea and Japan led to a sense of a vigorous anxiety and fear that "Japan will once again come to the Korean peninsula". As a reaction to this, the discourse on the criticism of 'Japanese Style' strongly emerged. If the prior discourse of criticism was to express the national antipathy toward the colonial remnants that had not yet been disposed of, the critical discourse of the 1960s was the wariness of the newly created 'Japanese Style' in popular culture, and to grasp it as a symptomatic phenomenon that 'evil-minded Japan' was revealed. Thus, this new logic of criticism of the 'Japanese Style' had a qualitative difference from the existing ones. It was accompanied by a willingness to inspect and censor the 'masses' that grew up as consumers of transnational 'mass culture' that flowed and chained in the geopolitical order under the Cold War system. Therefore, the topology of 'popular things=Japanese things=consuming things' reveals the paradox of moral demands that existed within Korean society in the 1960s. This was to solidify the divisive circulation structure that caused them to avoid direct contact with the other called 'Japan', but at the same time, get as close to it as ever. It is a repetitive obsession that pushes the other to another side through the moral segregation that strictly draws a line of demarcation between oneself and the other, but on the other hand is attracted to the object and pulls it back to its side. This paper intends to listen to the different voices that have arisen in the repetitive obsession to understand the significance of the dissonance that has been repeated in the contemporary era. This will be an examination of the paradoxical object of Japan that has been repeatedly asked to build the internal control principle of Korean society, or to hide the oppressive and violent side of the power, and that can neither be accepted nor destroyed completely as part of oneself.
