Antigenic components reacting with IgE and IgG antibodies were localized in muscular layer of adult and of larva, sparganum. But the antigenic components inducing IgG were localized at tegument and parenchyma in addition to muscular layer in adult and sparganum. Also in sparganum, the surface of calcareous corpuscles of parenchyma showed immunoreactivity to IgG antibody. However antigenic components inducing IgE antibody were not localized in tegument and parenchyma, but in adult worm, we observed the immunopositive reaction at the lining of vitelline follicles in mature proglottis and on surface of egg shell within uterus of graved proglottis. By the method of immunogold-labelling, we observed the location of antigenic particles in tegument of sparganum. The density of antigenic particles inducing IgG was higher than that of antigen particles inducing IgE in syncytial tegument, tegument cells. A total of 43 and 36 protein bands were resolved from crude extracts of adult and sparganum, respectively, by SDS-PAGE. 34 bands from crude extracts of adult and larva were migrated to same positions. By EITB, 21 bands of 44 bands in adult were recognized with IgG antibody, and also 21 bands of 36 bands in sparganum. 13 bands of them were common antigenic components both in the adult worm and sparganum. Because 19 bands of 44 bands in adult worm were reacted with IgE antibody, they were IgE antigenic component. In sparganum, 13 bands were IgE antigenic components. 9 bands of them were common antigenic component inducing IgE antibody in both a-dult and sparganum. 3 bands of antigenic component recognized by IgE and IgG antibody were nonspecific antigen in both adult and sparganum of Spirometra erinacei.

Purpose: A new health policy, referred to as the National Health Screening Program for Infants and Children, was launched in November 2007 by the Ministry of Health and Welfare and National Health Insurance Corporation in Korea. We have developed a nutrition-counseling program that was incorporated into this project. Methods: We reviewed the nutritional guidelines published by The Korean Pediatric Society and internationally well-known screening programs such as Bright Future in the United States. We also reviewed the recent Korean national surveys on nutritional issues, including the Korea National Health and Nutrition Examination Survey (KNHANES) and the 2005 National Survey of Physical Body and Blood Pressure in Children and Adolescents. The development of questions, pamphlets, computer programs, and manuals for doctors was carried out after several meetings of researchers and governmental officers. Results: We summarized the key nutritional issues according to age, including breastfeeding in infants, healthier complementary feeding, and prevention of iron deficiency anemia, establishment of healthier diets, as well as dietary prevention of overweight children with an emphasis on physical exercise. We have constructed a new Korean nutrition questionnaire and an anticipatory guidance program based on the primary care schedule of visits at 4, 9, 18, 30, and 60 months of age. Five to eight questions were asked at each visit and age-matched pamphlets for parents and guidelines for doctors were provided. Conclusion: We developed a nutrition-counseling program based on recent scientific evidence for Korean infants and children. Further research on this national program for screening the nutritional problems in detail and setting the therapeutic approaches may help identify areas of success as well as those that need further attention.

Efficacy of surface sterilization and physicochemical properties of electrolyzed water manufactured depending on electrolyte, materials, and type of electrolytic diaphragm used were investigated. Physical properties of electrolyzed water manufactured from diaphragm system showed the highest effectiveness under at distance between diaphragms of 1.0 mm and 20% NaCl supplying rate of 6 mL/min. ORP, HClO (should defined) content, and pH at above conditions were 1,170 mV, 100 ppm, and 2.5, respectively. Two-stage electrolyzed system was more effective than one-stage one. Electrolyzed water manufactured from non-diaphragm system at 4 mL/min supplying rate of 20% NaCl was similar to the most effective diaphragm system, whereas ORP, HClO content, and pH were 800 mV, 200 ppm, and 9, respectively. Sealed electrolyzed water could be preserved more than one month at room temperature with ORPs of 750 and 1,150 mV in non-diaphragm and diaphragm systems, respectively, and at HClO content of 100 ppm. Physicochemical properties of electrolyzed water manufactured from electrolytic diaphragm of $IrO_{2}$ and Pt+Ir were more effective than that of Pt. ORP and HClO contents of electrolyzed water manufactured from various electrolytes were high in order of NaCl>KCl>$CaCl_{2}$, whereas no differences were observed among electrolytes in sterilization efficacy. Twelve kinds of microorganisms tested (initial total count, $10^{5}-10^{6}CFU/mL$) were sterilized within 1-2 min by electrolyzed water.

To examine the EC model in a culture medium, basic culture medium of Rush (2005) and EC model of Robinson and Strokes (1959) were applied analyzing the equivalence ion total amount, the EC variable of cation and anion. Following the experiential translation by Steiner (1980), 130 optimized domestic and foreign culture media for crop growth were utilized, and estimated EC model was also demonstrated. Results from basic culture medium of Rush (2005) suggests an estimated EC by equivalence ion total amount and high reliable regressive model with 0.96 y = 1.33x - 0.23 of 0.96 as value $R^2$. It was found out that the change in concentration of positive ion and anion did not differ significantly with the increase and decrease of EC, however, there occurred a slight variable range. The change brings about a bigger anion influence than the previously reported positive ion, seemingly like those based on nitride ion and sulfur ion. The above EC estimated models confirmed that with optimized 130 domestic and foreign culture media for crop growth, the value derived will be as follows: $R^2$ = 0.98 with y = 1.23x - 0.02. In addition, the contour analysis of positive ion and anion for EC, with popularly known concentration range of EC $1.5-2.5dS{\cdot}m^{-1}$ reveals an equivalent of more than $11meq{\cdot}L^{-1}$ for positive ion and $15meq{\cdot}L^{-1}$ for anion. On the other hand, the left bottom, low concentration $1.5dS{\cdot}m^{-1}$ and the right above, high concentration $2.5dS{\cdot}m^{-1}$, for both positive ion and anion existed differently in a proper culture medium concentration. This study adapted variables of both positive ion and anion of EC simultaneously, unlike in the previous culture medium by ion ratio in mutual ratio of Steiner (1980), and offers an EC model that can estimate levels or positive ion and anion in proper concentration, EC $1.5-2.5dS{\cdot}m^{-1}$, with distributed features of ions.

This study suggests a spiritual education for the Christian family as a strategy to cope with the risky situation of the Korean Church during the Covid-19 pandemic. Today, we live in a chaotic epoch since the rapid development of the science caused the Fourth Industrial Revolution and the Covid-19 pandemic gave rise to a wide array of changes throughout the society. Korean Church in these circumstances is required to have relevant responses to the kaleidoscopic changes. Especially, not to mention the face-to-face public worship service, in the situation where the congregation members even find it difficult to meet one another in a small group, it becomes a crucial issue how Christians maintain their faith and community in the healthy spirituality. As such, viewing that Christian education within the family will become much more important, this study conducts research for familial-spiritual education. For the research, this paper, first of all, attempts to understand the era of Covid-19. It is to see what the Novel Corona Virus is and what the feature of the epoch of Covid-19 might be. Based upon the understanding, this research discusses what Christian spirituality is asked for and the orientation towards which Christian education should go on. It is particularly to say that a spiritual education for the family becomes integral. The education for the family might be possible through Bibliodrama so that this study establishes a specific model of Christian education employing Bibliodrama. The discussion above shows three academic significances. First, this paper, within the domain of Christian education, suggests an alternative research which is to solve Korean Church's diverse problems caused by Covid-19. Second, this research attempts an analytical understanding of the Covid-19 period within the Christian education area. Finally, when specific and practical research for the field of Christian education during the Covid-19 pandemic is required, this study considers that Christian education within the family is overarching, thus proposing a specific model for familial-spiritual education hiring Bibliodrama.

This study was conducted to investigate factors related to experience rate of low back pain(LBP) in the high school students, a questionnaire survey was carried out for 778 high school students in Andong city Kyungsang Pook province from 28th June to 10th July, 1993. The results were as follows: The experience rate of LBP for 778 high school students who were interviewed was 27.1 %. Unknown(47.4 %) was the highest in the cause of LBP. The experience rate of a academical high school students (57.8 %) was higher than the technical high school students(42.7 %) in association according to LBP and school division(P = 0. 001). The experience rate of 18 years old above students (60.2 %) was higher than 17 years old below school students(39.8 %%) in association between LBP and age(P = 0.031). The experience rate of students who go to bed at the hot floored bed (80.1 %) was higher than students who go to bed at the bed room (11.8 %) in association between LBP and room type(P = 0.012). The statisticaly significant variables related to LBP were school division, age and stress. It was revealed by this survey that independent variables related to LBP experience rate of high school students were important health problem. So the prospective research is need by those variables.

Three kinds of natural pesticides extracted from plants which are being sold in the Korean markets, were estimated effects on materials of art of museum. Tested samples were 1) silk fabrics : undyed, dyed(amur cork tree, gallut, gallut(alum post mordancy), gallut(copperas post mordancy), gardenia, turmeric, acorn, acorn(copperas post mordancy), gromwell, madder, madder(alum post mordancy), safflower, sappanwood, sappanwood(alum pre mordancy, post mordancy), indigo, indigo+amur cork tree, indigo+sappanwood) 2) cotton fabrics : undyed, dyed(amur cork tree, gallut, gallut(alum post mordancy), gardenia, acorn, acorn(copperas post mordancy), gromwell, madder, madder(alum post mordancy), safflower, sappanwood, sappanwood(alum pre mordancy, post mordancy), indigo, indigo+sappanwood) 3) undyed ramie fabric 4) Korean papers : undyed, dyed(sappanwood, indigo, gardenia, amur cork tree, safflower) 5) pigments : azurite, malachite, red lead, litharge, orpiment, hematite, iron oxide, cinnabar, vermilion, indigo, lake indigo, kaolin, lead white, oyster shell white 6) painted plates : azurite, malachite, red lead, litharge, orpiment, hematite, iron oxide, cinnabar, vermilion, indigo, lake indigo, kaolin, lead white, oyster shell white. Conditions of tests were that after samples were exposed to 10 times of promoted concentration for 9 months in relative humidity $55{\pm}1%$ and temperature $20{\pm}2^{\circ}C$, they were compared with standards. Items of estimation were color difference(${\Delta}E^*$) and tenacity. After exposure to pesticides, undyed silk cotton ramie fabrics and Korean papers were not nearly changed in their colors, but colors of most of dyed samples were clearly changed by pesticides except for partial samples(acorn- and madder-dyed fabrics etc, gardenia-dyed samples). Especially changes of colors of turmeric-dyed silk fabrics were most distinct. And colors of pigments and painted plates containing lead, copper, arsenic, mercury and vegetable pigments, were clearly changed. Tenacities of yams of undyed silk fabrics were not nearly changed and undyed cotton fabrics were a little reduced as compared with standards. But tenacities of yams of dyed silk and cotton fabrics were clearly reduced or increased as compared with standards. Especially, madder-dyed silk fabrics were increased 10% or more and indigo-dyed silk fabrics were reduced 10% or less in all pesticides. Also madder- and sappanwood(alum post mordancy)-dyed cotton fabrics were increased 10% or more in all pesticides.

The 'Wat Phou and Associated Ancient Settlements within the Champasak Cultural Landscape' of Laos was designated as a UNESCO World Cultural Heritage in 2001. The uppermost structure of the Sanctuary in Wat Phou has been destroyed and being variably damaged, maintenance is required through scientific and systematic diagnosis. The Sanctuary of Wat Phou was constructed mainly using sandstones and bricks. There are physical damages including fracture, break out, exfoliation and interval as well as biological damages by lichen, mosses and weeds. According to the ultrasonic velocity measurement and property evaluation of the sandstones of the Sanctuary in Wat Phou, weathering index of the eastern side sandstones is 0.10 to 0.74 (mean 0.36), showing MW grade. Southern and northern side sandstones have relatively higher properties with average weathering indices of 0.30 and 0.32. The results of slope analysis of the Sanctuary, indicated that the 4th spot in the southern side has the largest slope of $5^{\circ}W$, seemingly due to the unstable ground around the Sanctuary. Based on the relative level measurement and past drawings, the Sanctuary is verified to have been located on ground with a certain slope rather than flatland. The ground of the southern side is inclined $1.51^{\circ}$ more than that of the northern side, which will affect the structural stability of the temple. The interval width of the selected southern spot is the largest with an average width of 159.5 mm, and the largest width is 328.3 mm at the top, since the width increases above rather than below, seemingly due to the unequal subsidence of the ground. Constant maintenance for conservation is required for the structural stability of the Sanctuary in Wat Phou, which was partly collapsed and has also suffered physical damage.

HDBPDA ion exchange resin, {(4, 5) : (13, 14)-Dibenzo-6, 9, 12-trioxa-3, 15, 21, -triazabicyclo [15. 3. 1]heneicosa-(1, 17, 19)(18, 20, 21) triene ion exchange resin : HDBPDA ion exchange resin} had a capacity of 3.8meq/g dry resin. The distribution coefficients of alkali and alkaline earth metal ions on HDBPDA and strongly acidic cation exchange resin, Dowex 50W-X8(200-400mesh) in water, and the various concentrations of hydrochloric acid were determined. Concentration of hydrochloric acid have almost not influenced on the distribution coefficients of alkali and alkaline earth metal ions for the HDBPDA ion exchange resin, but generally the distribution coefficient slightly increased with decreasing concentration of hydrochloric acid. The distribution coefficients of metal ions in water are larger than those in various hydrochloric acid concentration. The distribution coefficients of alkali and alkaline earth metal ions for the Dowex 50W-X8 ion exchange resin increased with decreasing hydrochloric acid concentration. Especially, the distribution coefficients of alkaline earth metal ions increased rapidly compared to those for alkali metal ions. The distribution coefficients of alkali and alkaline earth metal ions on HDBPDA ion exchange resin increased in a linear manner with decreasing acid concentration, and the slope, d log Kd/d log $M_{HCl}$ is about -0.2. Of the distribution cofficients of alkali metal ions on Dowex 50W-X8, at range of moderate hydrochloric acid concentration, the slope is about -1, while the slope for alkaline earth metal ions is about -2. However, at very low hydrochloric acid concentration, the linear variation between distribution coefficient and acid concentration was not occurred, but the slope was deviated from above values at low acid concentration.
