The purpose of this study was to compare the ability of Northeast Asians to discriminate the salinity in salt solution and foods, and to compare their preference of salinity. Panels of Korean, Japanese and Chinese evaluated three kinds of samples that contained different level of salt such as salt solutions, julienned radish salad, Bulgogi. The salt levels had been manipulated to produce five samples of each one. The salt solutions were prepared by adding 0.3%, 0.7%, 1.1%, 1.5%, 1.9% salt into water. Different levels of salt in Julienned radish salad and Bulgogi were prepared by adding 0.5%, 1.5%, 2.5%, 3.5%, 4.5% salt to the recipe. The results of this study showed that the three ethnic groups had significant differences in their ability to distinguish the intensity of salinity in solutions containing a high contents of salt(1.5~1.9%). According to the regression analysis, Koreans(a=1.050) turned out to be the most able to detect the intensity of salinity, compared to the Japanese (a=0.988) and Chinese (a=0.807). All ethnic groups preferred a salt concentration of 0.3%, and the preference for this concentration was lower in Japanese than in Koreans and Chinese. There were significant differences in the perception of salinity in the julienned radish salad containing more than 3.5% salt between Koreans and Chinese. Koreans (a=1.168) appeared to be the most able to detect the intensity of salinity, compared to the Japanese (a=0.908) and Chinese (a=0.793). Both Koreans and Japanese had the strongest preference for the julienned radish salad containing a 1.5% salt concentration, while the Chinese preferred a salt concentraion of 2.5%. The ability of ethnic groups to detect the salinity in Bulgogi were significantly different at high salt -concentrations (more than 3.5%), and the awareness of salinity was as fallows : Koreans(a=0.161) > Japanese (a=0.896) > Chinese (a= 0.845). Koreans and Japanese had a higher preference or the Bulgogi containing a salt concentration of 1.5%, and the Chinese had higher preference at a salt concentration of 2.5%.

Objective : Migration can be a stressful process to people because they have to adjust a lot of things including habits, routine and cultural behavior. Also, Migrant can negatively impact on participation in daily meaningful occupations. Thus, the purpose of this research is to investigate whether participation in meaningful occupations after immigration and environmental factors impact the QOL in migrant women. Method : Migrant females who live in Australia were invited to participate in the study (n= 9). In this study, participation, environmental factors and QOL were measured using the questionnaire, which was developed by researchers. Purposive sampling was used to select the participants who were then asked to fill out a survey. Both quantitative data and qualitative data were collected. The SPSS program was used to process the quantitative data that was transcribed and coded. Result : Spearman's rank correlation coefficient shows that the total scale of QOL and the total scale of occupational engagement were significantly correlated at the 0.05 level. Conclusion : There was a significant relationship between quality of life and occupational engagements. Migrant women tend to have a lack of participation in meaning occupations thus, it seems to impact on their quality of life.

This article aims to reveal the ways in which a "space of difference" is produced and interpret the space as a heterotopic space, drawing the case of Filipino elderly care-givers in Israel. The in-betweens and temporariness of the migrants'experiences in the Israeli society lead to the creation of a heterotopic space. Paying attention to their particular life rhythm as live-in care-givers, namely weekdays-workplace and weekend-flat, this article explores how the migrant care-givers build their own society through a variety of spatial practices and multiple social relations based on the flat. In making the flat a perfect form of a lifestyle for their own, the migrants inscribe their presence in the flat in unique ways for different purposes, in a way different to that which surrounds it. However, the structure of flat not only signifies the migrants' marginality but also reflects the challenging position. The flat has functions in relation to all other space that remains, even if such connection often creates effects of contrast and difference. In this light, the flat is not merely an alienated and circumscibed exotic migrant enclave but a heterotopic space which is dynamically constructed in relation to other sites in the wider societal order.

The Neolithic relics containing sedimentary deposits have been found in the Moonamni coastal zone of the East Sea, Korea. The purpose of this research is to establish the late Quaternary stratigraphy of the coastal dune deposit and to elucidate its depositional environment of the Neolithic-site sediments on the basis of analytical properties of grain size population and mineralogy of the sediments. As a result, the vertical sections of the sediments from three trenches are characterized by three major stratigraphic depositional units of Unit 3, Unit 2 and Unit 1 in ascending order. Unit 3 and 2 can be further divided into tow sub-units. Unit 3 is composed of massive sands in the lower part and muddy sand in the upper part. It is considered that the Unit 3 is a typical dune deposit showing well-sorted sands. Unit 2 is characterized by the cross-bedding, and include archaeological remains such as pottery shards. This unit can be further divided into two sub-units of muddy sand in the lower part and sand in the upper part. Unit 1 occupies the top section and consists of modem dune sediment. The Neolithic cultural remains would be accumulated in the coastal dune area in relation to dynamic condition of beach system under the high stand of Holocene sea-level at about 7,800∼6,500 yr B.P. or so.

A new gerbera cultivar 'Paspin' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2009. A cross was made between 'Lilabella' and 'Mephisto' with purple and semi-double in 2005. After investigation of the characteristics for five years (from 2005 to 2009), it was selected specially as a cut flower. The 'Paspin' cultivar has a pastel pink flower color (RHS R52B) with green disc center and semi-double flower. It has large-sized flowers which average flower diameter is about 12.8 cm. And inner ray floret and disc diameters are 7.87 cm and 2.57 cm, respectively. It has an adequate peduncle height of 48.6 cm, and a longer vase life of 10.8 days. It is vigorous in growth and also adaptable to the local cultural environments of Korea. It is expected that if the 'Paspin' cultivar will be planted, the royalty fees to be paid to other countries can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.

Objectives: This study aimed to investigate stages of safety and health culture change through a reflection on 40 years of hearing conservation history at a multinational company. Methods: The target workplaces were multinational companies with more than 1,000 employees. The research used the clinical case study and system analysis methods based on direct observation of the research from 1994 to 2009. The latter method performed an analysis of the equilibrium state of the cross-section in the given period and the longitudinal profile of the change during the given period. Results: The stages of cultural change are divided into five stages and summarized as follows. In the first stage, workplace noise was not widely recognized as a hazard, while in the second stage, the measurement of noise levels and audiometric testing were conducted under the Korean Occupational Safety and Health Act (KOSHA). The driving force for change in the second stage was the amendment of the KOSHA. In the third stage, noise came to be recognized as a hazard factor through awareness training. The driving force of change during the third stage was the strong executive power exerted by the audit of the industrial hygiene program from the US head office. In the fourth step, there was a change to actually reduce noise. The driving force in this stage was a change in company executives' risk perception resulting from lawsuits over noise-induced hearing loss and the task force team activities for culture change based on the action learning protocol. At the fifth stage, a 'buy quiet policy' was institutionalized. The management's experience that noise reduction was difficult was the motivation to manage noise from the time of purchase of equipment. Conclusions: The activities of a hearing conservation program are determined by the improvement of the legal system and by the way it is enforced. Noise control activities to reduce noise areas may be possible through the shared risk perception of noise-induced hearing loss and by a change agent role as a facilitator to implement noise control.

Owing to the saturation of ground spaces in downtown areas, underground spaces are being developed increasingly. Underground spaces are utilized for transportation, water supply and sewerage, communication zones, electric power zones, and various cultural complexes. In Korea, for excavating underground spaces, blasting methods using gunpowder such as the New Austrian Tunneling Method (NATM) are mainly used. However, the blasting method causes vibration and noise during tunnel excavation, generating many complaints from residents in the vicinity of the excavation site. To address this problem, various methods have been developed, and recently, vibration and noise have been reduced using deep excavation. This study predicts blast vibration changes according to the depth, under the same blasting and tunnel conditions, using numerical analysis based on the blast vibration measurement data of the GTX-A route, the tunnel cross-section drawings, and ground investigation reports. Furthermore, the necessary separation distance from densely populated areas such as residential areas is suggested by analyzing the trend of decreasing blast vibration according to the distance from ground surface directly above the blasting location.
