For a measure against late transplanting, this experiment was conducted to investigate a reasonable seeding rate in nursery bed and a proper nursery size. The treatments applied to this experiment are as follows a) seeding rates: 0.2ι, 0.4ι and 0.6ι per 3.3$m^2$ b) nursery sizes. for 10a-field area: 39.6$m^2$, 49.5$m^2$ and 59.4$m^2$ c) transplanting dates: June 5, June 25 and July 15. The seeding date was April 26 and planting density was determined by the number of sound seedlings based on the combination of seeding rate and nursery size. The results may be summarized as follows: 1. In seedlings both increased nursery period and decreased seeding rate showed a remarkable-increase in plant height, number of leaves, dry matter weight and the ratio of dry weight to plant height. But their number of tillers and live leaves did not show such tendency. 2. Delayed transplanting date shortened culm length and panicle length as well as number of days from transplating to heading and it also delayed heading date. On the other hand the transplanting of 80-day seedlings resulted in premature heading. 3. As a result late transplanting reduced number of spikelets per panicle, maturing rate and 1000-grain weight. In the last analysis it linearly reduced grain yield. The decreasing rate of yield by late transplanting was 15.6% in June 25 plot and 41. 3% in July 15 plot, compared with the yield in June 5 plot. Such a remarkable decrease in yield of the extremely late transplanted plot was mainly due to markedly decreasing number of spikelets per panicle and 1000-grain weight. 4. Both increased seeding rate and nursery size gave a rise in number of tillers per unit area as well as number of transplanting hills but gave a fall in culm length and panicle length. 5. Accordingly, though thick seeded - dense planted plot increased number of panicles per unit area, decrease in number of spikelets per panicle and 1000-grain weight made no differences in yield between thick seeded - dense planted plot and thin seeded - sparse planted one. However, the yield in the thick seeded - dense planted plot transplanted on July 15 was reduced owing to the remarkable decrease in maturing rate and 1000-grain weight. 6. We came to the conclusion that as a measure against the extremely late transplanting the suitable seeding rate was 0.4ι per 3.3$m^2$ and the proper nursery size was 59.4$m^2$ for 10a-field area.
This paper aims to identify the characteristics and the current situation of the architectural characteristics, children's characters using facilities, and status of management and utilization by surveying 'Day Service for Children' in Tokyo-do. First, About the status of management and utilization, 'Day Service for Children' is operated by a local government, NPO corporate group and social welfare corporate. There are not big differences of the care program or running hours depending on operating principals but there are differences depending on staff organization, number of children and space constitution. Also, infants ratio at 'Day Service for Children' is high for the purpose of detecting disability early and supporting their development early. They have diverse disabilities but developmental disabilities' ratios high and most children are using both this facility and normal nursery centers together. Samples for proper child care based on status of space constitutions were installing lock, raising door knobs and using softer floor materials which are for children's safety. For the problem of space utilization, most comments were about lack of space which is not enough for teaching and training materials. Therefore, as an example, observation rooms for parents and teachers were sometimes used as storages and it changes teachers' moving direction, staying area and behavior zone. The programs of 'Day Service for Children' are divided to group teaching and private one. It will be the best if they have separate spaces such as group class room, private class room and play room. When they were operated by NPO corporate group or Social welfare corporate, there are many cases that their space was not properly zoned for each activity.

To investigate the effects of seeding date, nursery days and plug cell size on seedling growth and quality of waxy corn. This study was carried out in the field of the National Institute of Crop Science in 2007. Varieties used were two waxy corn hybrids cvs. Chalok# 1 and Chalok# 4. The plant height, number of leaves and dry weight of waxy corn seedlings were significantly affected by seeding dates and plug cell size, while no differences between varieties. The growth of seedlings was faster in March 14 seeding than in May 8 and July 4 seedings. Based on plant height, March 14 seeding, May 8 seeding and July 3 seeding reached suitable size for transplanting after 30 days (21.6cm), 15 days (25.5~26.9cm) and 10 days (21.6~24.0cm) in the nursery, respectively. Seedlings of March 14 seedling and May 8 and July 3 seeding reached suitable number of leaves i,e. 2~3 leaves, 15~20 days after seeding on March 14 and 10 days after seeding on May 8 and July 3. Dry weights of 30 days seedling for March 14 seeding, 20 days seedling for May 8 seeding and 15 days seedling for July 3 seeding were 0.43g, 0.57~0.67g and 0.53g, respectively, and the dry weight of seedlings increased by 2~3 folds at the later nursery days. The suitable nursery days of waxy corn were 20 days on March 14 seeding and 10~15 days on May 8 or July 3 seeding.
Comprehensive studies on seedling production and transplanting cultivation of waxy corn are necessary to fulfill the comsumer's preference for the high quality whole ear waxy corn and its year-round supply for higher price, and to escape marketing in a short period at harvest season. Two waxy corn hybrids (cv. Chalok# 1 and Chalok# 4) were used to study the effects of seeding date, nursery days and plug cell size on growth and yield of waxy corn, and to clarify the reliable transplanting date at the Experimental Field of the National Institute of Crop Science in 2007. The number of days from seeding to silking was increased as nursery days were extended, but the number of days from transplanting to silking was shortened comparing to the direct seeding. Number of days from seeding to silking was shorter by 9~12 days for Chalok# 1 than for Chalok# 4, while the number of days from seeding to silking was shorter by 12~15 days in the second cropping than in the first cropping. Culm length of transplanted waxy corns was decreased as the nursery days were extended. Culm length of seeded Chaok# 1 and Chaok# 4 were decreased by 17% and 24%, respectively, in the second cropping compared to those in the first cropping. Ear length was somewhat decreased as the nursery days were extended. Chalok# 1 in the second cropping the degree of decrease was much higher in second cropping than in first cropping of Chalok# 1. Comparing to the first cropping, number of marketable ears per 10a of Chalok# 1 decreased as high as 64%, while that of seeded Chalok# 4 decreased mere 12% in the second cropping.
Purpose: This study was conducted to verify model for predicting health promotion behavior and the health status of child care teachers based on Pender's health promotion model and Dahlgren and Whitehead's health determinants model. Methods: The data was collected from January to February 2018 from 205 child care teachers in day care centers in Seoul. Results: This model was suitable to explain the health status and health promotion behavior of child care teachers. In this study, health promotion behavior had the most direct affect on the health status of child care teachers. Health promotion behavior was directly affected by social support, self-efficacy, and depression. Job stress had an indirect affect on health promotion behavior. Conclusion: Considering the factors identified in this study that influence the health promotion behavior of child care teachers, we propose the development of interventions to improve the health status of child care teachers.
The common squid $Todarodes$$pacificus$ is a dominant species in Korean waters, where it is captured preponderantly by the angling fishery. The spawning and nursery grounds of $T.$$pacificus$ extend from the southern East Sea to the northern East China Sea. Consequently, the environmental conditions in this area during the spawning and nursery seasons might affect the abundance of $T.$$pacificus$. This study, analyzed the relationship between the distribution of zooplankton and the abundance of $T.$$pacificus$ and variation in the squid angling fishing grounds in Korean waters. There was a positive relationship between the fluctuations in zooplankton and the catch per unit effort (CPUE; $kg{\cdot}day^{-1}{\cdot}person^{-1}$) of the angling fishery in the East Sea of Korea. The main fishing season is from July to December and the CPUE was closely related to the zooplankton biomass in April in the East Sea. Recently, the center of the squid jigging ground has moved drastically from the area around Ulleung Island to the northern East Sea. We postulate that the fishing grounds of the squid angling fishery will move farther north with climate change.
The objective of this study was to evaluate Solpro500 (a wheat hydrolysate containing a high level of glutamine) as a replacement for spray dried porcine plasma (SDPP) in diets fed to nursery pigs. One hundred and eight pigs (Dalland, $5.39{\pm}0.80$ kg BW) weaned at 21 days were assigned to one of three treatment groups for a 28 day feeding trial. The experimental diets were based on corn and soybean meal and were supplemented with either 8% SDPP, 4% SDPP plus 4% Solpro500 or 8% Solpro500. Each treatment was fed to six pens with six pigs per pen (4 barrows and 2 gilts). The experimental results indicated no significant difference (p>0.05) in daily gain, feed intake or feed efficiency for pigs fed the three experimental diets. However, the diarrhea index for pigs fed either 4% SDPP and 4% Solpro500 or 8% Solpro500 was lower (p<0.05) than that for pigs fed 8% SDPP. No differences (p>0.05) were found in the apparent fecal digestibility of dry matter, organic matter or crude protein between pigs fed the three diets. The intestinal morphology (villous height, villous width and crypt depth) was not affected by diet treatments (p>0.05). In conclusion, Solpro500 SDPP can replace SDPP without any negative effects on nursery pig performance.
The purpose of this study was to suggest the justification for social recognition of childcare staff through a review of Axel Honneth's recognition theory of childcare staff's caring work, the Constitution, the Infant Care Act, and the National Human Rights Commission Act. As a result of the study, first, the poor working environment of childcare staff was confirmed. Despite the continuous intervention of childcare policies to improve the working environment of childcare teachers, poor working conditions such as annual/monthly vacation and rest time guarantee were confirmed. Second, the human rights violations of childcare staff were confirmed. The installation of CCTV installed to prevent child abuse in childcare institutions confirmed not only the human rights violations of childcare staff but also the psychological pressure of childcare staff who are monitored 24 hours a day. Third, this study has significance in that it suggests the justification for social recognition of childcare staff through revision and supplementation of the current law for appropriate performance evaluation of childcare.

This study was conducted to evaluate the effects of brown rice (Japonica) on growth performance, nutrient digestibility, and blood parameters of weanling pigs. A total of 60 weanling pigs (28-day-old, 30 barrows and 30 gilts, 6.73 ± 0.77 kg body weight [BW]) were randomly allotted to 2 dietary treatments (6 pigs per pen; 5 replicates per treatment) in a randomized complete block design with the initial BW and sex as blocks. The dietary treatments were a typical nursery diet based on corn and soybean meal (CON) and the CON replaced 50% of corn with brown rice (BR). Pigs were fed respective dietary treatments for 5 weeks. For the last week of experiment period, pigs were fed respective dietary treatments containing 0.2% chromic oxide as an indigestible marker. Fecal samples were collected from randomly selected 1 pig in each pen daily for the last 3 d after the 4-d adjustment period. Blood was collected from randomly selected 1 pig in each pen on d 0, 3, 7, and 14 after weaning. Compared with pig fed CON diet, pigs fed the BR diet were found to have higher (p < 0.05) final BW, overall average daily gain, and apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of dry matter and energy. However, there were no significant differences between the groups with respect to average daily feed intake, gain to feed ratio, frequency of diarrhea, and the AID and ATTD of crude protein during overall experimental period. Similarly, there were no significant differences on blood parameters between the groups. Thus, the findings of this study indicate that brown rice (Japonica) can be used to replace 50% of corn in the diet of pigs during the nursery period without negatively affecting growth performance, nutrient digestibility, or blood parameters.
Child abuse is defined as any type of maltreatment and neglect by an adult, which is violent or threatening for a child, including physical violence directed to the child. Children could be abused not only by a parent or caregiver, but also by other adults on whom they are dependent, such as day nursery workers, teachers, and sports coaches. While doctors are the most responsible people for reporting any type of child abuse, their care and awareness seem to be very poor and weak. We reviewed 30 autopsy cases of child abuse, in particular during the past 20 years in Jeju Island. We expect that doctors will report any child abuse more actively after reading this review article.
