  • The effect of frozen storage on some physicochemical and sensory quality of salted Chinese cabbage and Kimchi were investigated. The texture of the fresh Chinese cabbage was preserved better by emersion quirk freezing or predrying than by air slow freezing or no predrying while no effect was measured on the salted Chinese cabbage. The salted cabbage had less frozen damages than the fresh one and had the similar texture characteristics of the fermented Kimchi. The frozen Kimchi had the similar overall quality to the unfrozen fermented Kimchi in spite of a little higher chewness values. The color of the salted Chinese cabbage was a little changed to pinkish after 3 months frozen storage but Kimchi was maintained the good quality after 6 months.

  • The oil immersion method can be used to create objective lenses with long working distances without sacrificing the focusing resolution for laser processing. In this study, a space in which air or oil can be filled was formed in the middle of a lens for analyzing the optical properties of a liquid-oil immersion lens. As the refractive media, air and oils of different refractive index values (1.2 and 1.5, respectively) were used. A simulation was conducted in the ZEMAX software environment using the ray-tracing technique, and the performance of the oil immersion lens was verified by determining its image distortion and focal length (FL) in each medium. In the case of air, the calculated FL was 0.813 mm, whereas the imaged FLs were 1.594 mm and 8.126 mm when the refraction indices were 1.2 and 1.5, respectively. The FL of an oil immersion lens could be increased considerably. In terms of image distortion, the oil immersion lens exhibited little distortion at the center in all cases, but different degrees of image distortion were observed at different points away from the center depending on the refraction index degree.

  • In this present study, we determined whether or not there is an immunoadjuvant effect of ochnaflavone, a biflavone isolated from Lonicera japonica. As an antigenic source, the cell wall (CACW) of Candida albicans, a fungal pathogen, was used. CACW consists of 95% carbohydrate (mannan). In the experiments, BALB/c mice were immunized with emersion forms of CACW combined with or without ochnaflavone (Och) in the presence of IFA containing mineral oil or CACW alone. Then, the amounts of antisera collected from these mice groups were measured by the ELISA method. Data from these experiments showed that CACW combined with Och (CACW/Och/IFA) provoked the production of antisera app. 2.2 or 5 times more than the corresponding CACW/IFA or CACW alone (CACW/DPBS), respectively, in mice (P<0.05). We further examined the immune response type induced by Och. Analysis of the values of the IgG1/IgG2a ratios obtained from IgG isotyping revealed that Och induced Th2-immunity more dominantly than Th1. This finding was confirmed by cytokine profile. CACW/Och/IFA formulation induced IL-4 (Th2-type cytokine) more than IFN${\gamma}$ (Th1-type cytokine) as compared with CACW/IFA and CACW/DPBS formulations (P<0.05). All data combined, Och appears to have an immunoadjuvant activity that may convert Th1 immunity into Th2 immunity.

  • Variation in triacylglycerols(TGs) and fatty acids in Fucus serratus was analyzed for a period of one year. TGs were more concentrated during the summer(2.8mg/g dw)and autumn(2.6mg/g dw) than during the spring (0,7mg/g dw)and winter (0.5mg/g dw). The dominant fatty acides in total liqid were palmitic acid ($C_{16:0}$, 24.1%), oleic acid (($C_{18:1}$, 22.4%) and arachidonic acid (($C_{20:4}$, 14.4%) but the dominant ones in TG were $C_{16:0}$(22.8%), $C_{18:1}$(36.4%) and $C_{18:2}$(linoleic acid, 16.4%). The levels of $C_16$ fatty acids were high in winter while $C_18$ in summer and autumn. The polyunsaturated fatty acids (UFAs) were more abundant in the $C_20$ series, while the UFAs of the $C_16$ were low. Especially, the amount of arachidonic acid ($C_{20:4}$, 14.4% of total fatty acids (TFA) was more abundant than that of eicosapentaenoic acid ($C_{20:5}$, 10.4% of TFA). The amount of $C_{20:4}$ and $C_{20:5}$,in TG was 9.2% and 4.8%, respectively. These UFAs in total lipid were thus higher than TG. Therefore, the synthesis of TG and fatty acid was stimulated by the alternation of emersion and submersion of thalli from sea water and eco-physiological conditions during summer: high temperature and light, and low concentration of nitrogen.

  • In this study, ASTM C 1202 which is most commonly used for evaluating the penetration resistance into the concrete is reviewed. The test results by ASTM C 1202 showed that the passed charge could be underestimated as the $OH^-$ ion concentration in the concrete is lowered when the concrete is mixed with the admixtures. Therefore, the modified method using the distilled water was proposed in the paper. According to the test results, the modified method is not susceptible to $OH^-$ ion and temperature rise. In addition, the long term emersion test for the concrete mixed with the admixtures in the NaCl solution showed that the chloride diffusion coefficient tested by the modified method have higher correlation compared to the conventional ASTM method.

  • Due to the emersion of J2EE (Java 2, Enterprise Edition), many enterprises inside and outside of the country have been developing the enterprise applications appropriate to the J2EE model. With the help of the component model of Enterprise JavaBeans (EJB) which is the J2EE core technology, we can develop the distributed object applications quite simple. EJB application can be implemented by using the component-oriented object transaction middleware and the most applications utilize the distributed transaction. Due to these characteristics, EJB technology became popular and then the study for EJB based application has been done quite actively. However, the research of techniques for the performance monitoring during run-time of the EJB applications has not been done enough. In this paper, we propose the techniques for monitoring the performance of EJB Application on the run time. First, we explore the workflow for the EJB application service and classily the internal operation into several elements. The proposed techniques provide monitoring the performance elements between the classified elements. We can also monitor by extracting the performance information like state transition and process time of the bean which is related to the lifetime occurred during one workflow, and the resource utilization rate.

  • This study was conducted to determine the cause of the occurence of marginal leaf chlorosis in ginseng plants (Panax ginseng C.A. Meyer), and to determine its emersion in fields (practically) and in pots (experimentally). The following results were obtained. In the Present investigation, ginseng plants raised in acidic soil containing a high a moue t of Mn showed marginal leaf chlorosis. Henre it Ivas suggested that the shoot growth and root weights became grad gractually lower. The leaves having marginal leaf chlorosis contained low amounts of N, P,. Ca, Mg, and Na and the Fe/Mn ratios were low. There was a corresponding increase in Mn uptake. It was founrl that in soils where marginal leaf chlorisis occured the pH urar brlolv 4.2 to 4.9 and the Ca, Mg and Na content was decreased thus effectively increasing the available manganese in the soil. The Mn/Fe ratios in the yellow leaf margins of ginseng Plants affected by the Mn toxicity was over 2.0 compared to the general Mn/Fe ratio of 0.50 for healthily leaves, stems and roots. Typically when ginseng plants grow fields having soil with a pH below about 5.0, there tenor to be an uptake of excess Mn. When ginseng plants are grown in a nutrient sand culture solution It with an increased Mn concentration, they accumulate large amounts of Mn in the roots and in the shoots. In both casts marginal leaf chlorosis appeared in the emersions. In the Present investigation, ginseng plants raised in acidic soil and containing a high amount of Mn showed marginal leaf chlorosis.

  • Indonesia has a wealth of traditional textiles that are spread in every corner of its region, each of them has its own characteristics and uniquennes. Among the diversity of decorative and techniques used, there are also peculiarities arising from the coloring techniques, that is staining with natural dyes. The existence and the authenticity of the coloring techniques are still retained in some places in Indonesia until today. Generally, these societies make the fabric-making process as part of the ritual beliefs. One of which are the societies in Tenganan, Bali, an area in Bali which always use fabric as an important part in every traditional ceremony. The fabrics is known by the name Geringsing. The typically color which shown and also the sacred values that accompany make Geringsing a very special woven fabric and cannot be found in other areas. This is one of the local geniuses that need to be preserved. In addition to its unique techniques and special materials, Geringsing woven also keeps its myth and its philosophy. The emersion of Geringsing woven closely related to the community trust in God Indra as the main protector deity. The necessary initial process of making Geringsing is holding special ceremony attended by various circles of Tenganan village society. People in Tenganan believe that Geringsing is a precious heritage avoiding all diseases and disorders of evil spirits.

  • This work represents results of analysis of tidal observations at twelve major ports(Inchon, Kunsan, Mokpo, Daeheuksando, Jeju, Yeosu, Jinhae, Busan, Pohang, Ulsan, Mugho, Sogcho) around Korean coast for the years up to 1979. The reduction of hourly tide gauge sea level records provided by Korean Hydrographic Office was performed in systematic manner resulting digitised hourly observed series, predicted series and residual series. As a first step the application of an extended harmonic method of analyzing the tidal observations leads to the identification of 42 new constituents including 60 orthodox Doodson's constituents at major ports. The sea level statistics including sea level frequency distribution are presented and the tidal emersion curves showing the percentage of time for which different levels are covered by water and exposed are also presented to provide useful design input for coastal development. This study has teen undertaken in association with the programme of sea level research at Korean Hydrographic Office and the programme of adjustment of first order levelling network at National Geographic Institute.
