The Act on Special Cases Concerning the Punishment, etc. of Child Abuse Crimes intends to encourage reporting and punishment of child abuse by using the concept of 'crime' in child abuse cases. Article 10 of the Act imposes duty to report child abuse on a number of different professions, including medical professionals. Currently, more than 80% of child abuse cases occur among family members and the detection rate of child abuse is as low as 0.5% in Korea. On the other hand, medical professionals can identify child abuse relatively clearly with specific medical opinions. Therefore, it is necessary that medical professions are informed of this duty and does not bear disincentive from reporting. This paper makes policy suggestions in this regard. First, it is necessary that medical students and medical professionals receive regular education about the obligation to report child abuse. Education should include details of the reporting duty, as well as the fact that there is legal obligation to report even if the child abuse is "suspicious", not certain. Second, it is imperative to establish and implement protective programs for medical professionals who report child abuse. The current law provides a rough framework for protection of people who report child abuse, but it is necessary to produce detailed guidelines that are applicable in the context of medical setting. Education for medical students and medical professionals should include the contents of these guidelines, so that they do not hesitate reporting because they fear the aftermath of reporting. Third, it is highly recommended that physicians use the national Baby/Infant Health Checkup Program as an opportunity to detect child abuse. In Korea, the Baby/Infant Health Checkup Program provides physicians to periodically monitor health condition of all babies and children until the age of 71 months. In order to utilize this program for early detection of child abuse, it is imperative that the bBaby/Infant Health Checkup Program is modified to involve child abuse experts and medical professionals who participate in the program are educated about child abuse.

Background: Retrograde cerebral perfusion(RCP) is currently used for brain protection during aorta surgery, however, for the safety of it, various data published so far are insufficient. We performed RCP using pig and investiaged various parameters of cerebral metabolism and brain injury after RCP under deep hypothermia. Material and Method: We used two experimental groups: in group I(7 pigs, 20 kg), we performed RCP for 120 minutes and in group II (5 pigs, 20 kg), we did it for 90 minutes. Nasopharyngeal temperature, jugular venous oxygen saturation, electroencephalogram were continuously monitored, and we checked the parameters of cerebral metabolism, histological changes and serum levels of neuron-specific enolose(NSE) and lactic dehydrogenase(LDH). Central venous pressure during RCP was mainained in the range of 25 to 30 mmHg. Result: Perfusion flow rates(ml/min) during RCP were 130$\pm$57.7(30 minutes), 108.6$\pm$55.2(60 minutes), 107.1$\pm$58.8(90 minutes), 98.6$\pm$58.7(120 minutes) in group I and 72$\pm$11.0(30 minutes), 72$\pm$11.0(60 minutes), 74$\pm$11.4(90 minutes) in group II. The ratios of drain flow to perfusion flow were 0.18(30 minutes), 0.19(60 minutes), 0.17(90 minutes), 0.16(120 minutes) in group I and 0.21, 0.20, 0.17 in group II. Oxygen consumptions(ml/min) during RCP were 1.80$\pm$1.37(30 minutes), 1.72$\pm$1.23(60 minutes), 1.38$\pm$0.82(90 minutes), 1.18$\pm$0.67(120 minutes) in group I and 1.56$\pm$0.28(30 minutes), 1.25$\pm$0.28(60 minutes), 1.13$\pm$0.26(90 minutes). We could observe an decreasing tendency of oxygen consumption after 90 minutes of RCP in group I. Cerebrovascular resistance(dynes.sec.cm-5) during RCP in group I incrased from 71370.9$\pm$369145.5 to 83920.9$\pm$49949.0 after the time frame of 90 minutes(p<0.05). Lactate(mg/min) appeared after 30 minutes of RCP and the levels were 0.15$\pm$0.07(30 minutes), 0.18$\pm$0.10(60 minutes), 0.19$\pm$0.19(90 minutes), 0.18$\pm$0.10(120 minutes) in group I and 0.13$\pm$0.09(30 minutes), 0.19$\pm$0.03(60 minutes), 0.29$\pm$0.11(90 minutes) in group II. Glucose utilization, exudation of carbon dioxide, differences of cerebral tissue acidosis between perfusion blood and drain blood were maintained constantly during RCP. Oxygen saturation levels(%) in drain blood during RCP were 22.9$\pm$4.4(30 minutes), 19.2$\pm$4.5(60 minutes), 17.7$\pm$2.8(90 minutes), 14.9$\pm$2.8(120 minutes) in group I and 21.3$\pm$8.6(30 minutes), 20.8$\pm$17.6(60 minutes), 21.1$\pm$12.1(90 minutes) in group II. There were no significant changes in cerebral metabolic parameters between two groups. Differences in serum levels of NSE and LDH between perfusion blood and drain blood during RCP showed no statistical significance. Serum levels of NSE and LDH after resuming of cardipulmonary bypass decreased to the level before RCP. Brain water contents were 0.73$\pm$0.03 in group I and 0.69$\pm$0.06 in group II and were higher than those of the controls(p<0.05). The light microscopic findings of cerebral neocortex, basal ganglia, hippocampus(CA1 region) and cerebellum showed no evidence of cerebral injury in two groups and there were no different electron microscopy in both groups(neocortex, basal ganglia and hippocampus), but they were thought to be reversible findings. Conclusion: Although we did not proceed this study after survival of pigs, we could perform the RCP successfully for 120 minutes with minimal cerebral metabolism and no evidence of irreversible brain damage. The results of NSE and LDH during and after RCP should be reevaluated with survival data.

We investigated environmental problems related to clothing, and attempted their practical solutions using Future Problem Solving Program in order to cultivate the creative character in teenagers. We applied "teaching and learning plans" to seventy-seven the first graders of high school students in 2 classes in Gyeonggi-do, one hour per day for 3 weeks, from August 23 to September 8 2011. Statistical analyses were performed using the SPSS for Windows software(version 17.0). Mean differences in results between pretest and posttest were evaluated using Student's t-test. We selected 'production of fabrics, production of clothing, disposal and recycling of clothing and washing of clothing' as the learning theme in educational content factors of 'clothing culture in consideration of environment'. And we developed thirteenth teaching and learning plans and educational materials including 4 problems, 2 worksheets, 10 team worksheets, 7 video materials and 7 Power Point materials using Future Problem Solving Program(FPSP). The measurements of fluency, flexibility, originality and problem-solving ability are significantly improved. The level of creativity in the items of fluency, flexibility and originality, in particular, exhibited marked improvement, 'below-average' to 'above-average', regardless of academic records and gender. Problem-solving ability in female students was more effective than that of male, but it showed no significant correlation with academic records. The analysis of character-change showed the highest improvement in the awareness on the protection of environment, the character factor in the educational contents. Personalities, confidence, consideration and cooperation in learning method of FPSP also exhibited a significant improvement. But character-change did not correlate with academic records or gender. In the present study, we found that home economics has a positive effect on cultivating creative character. When we selectively and properly apply a course of creative problem-solving of FPSP and a course of creative output to students, we can increase their ability to solve problems, cultivate their creative character and further enhance their interest on home economics.

Caesium radioisotopes, ¹³⁴Cs and ¹³⁷Cs which come from the atmospheric nuclear tests and discharges from nuclear power plants, are very important to study artificial radioactivity. In this work, in order to lower the minimum detection activity (MDA) we investigated environmental radioactivity according to the Environment Measurement Laboratory procedure by ¹³⁷Cs and ¹³⁴Cs which is similar to chemical and environmental behaviors of ¹³⁷Cs. The environmental soils in high mountain areas near nuclear power plant were collected, and an Ammonium Molybdophosphate (AMP) precipitation method, which showed high selectivity toward Cs⁺ ions, was applied to chemically extract and concentrate Caesium radioisotopes. Radioactivity was estimated by a gamma-ray spectrometry. In gamma energy spectrum, with an increasing of ⁴⁰K radioactivity, it increased the MDA of ¹³⁴Cs and ¹³⁷Cs. Therefore, if the natural radionuclides were removed from the soil samples, the MDA of Caesium may be reduced, and the contents of ¹³⁷Cs of in the environmental soils can effectively be estimated. In the standard soil sample of Korea Institute of Nuclear Safety, radioactivity of ⁴⁰K was removed more than 84% on average, and the MDA of ¹³⁴Cs was reduced 2 times. The content of ¹³⁷Cs was recovered over 84%. On the other hand, in environmental soils, AMP precipitation method showed removal ratio of ⁴⁰K up to 180 times, which reduced the MDA about 5 times smaller than those of Direct method. ¹³⁷Cs recovery ratio showed from 54.54% to 70.06%. When considering the MDA and recovery ratio, AMP precipitation method is effective for detection of Caesium radioisotopes in low concentration.

In this study, the progress of domestic cultural properties designation, the changes and problems in classification were examined, and the relationship among Traditional Pal-kyung, Dongcheon-gukok, and Modern Pal-kyung were investigated targeting total of 68 cases of state-designated cultural properties of scenic sites in order to show that the traditional significance and value are being inherited today. The major results of this study are as follows. First, increase in scenic site designations with historical, cultural, and scenic characteristics can be viewed as an active intent to embrace the concepts such as cultural utilities, historical characteristics, literary value, and ideological backgrounds, which were specified as the basis for designation in the early Cultural Property Protection Law. Accordingly, it is very encouraging that the concept of cultural attractions such as traditional gardens and observatory points are regarded as an important standard for designation of scenic sites. Second, as for the classification of scenic sites per type, it was found that 'places with excellent natural scenery' were 44.16%(30 cases), followed by 'famous buildings or gardens and places with important legend' occupying 30.9%(21 cases), 'places with famous scenery' occupying 13.2%(9 cases), 'places with outstanding historical cultural and scenic value' that occupying 10.3%(7 cases), and 'animal and vegetation habitat with beautiful scenery' (1 case). Third, according to the current classification standards for scenic sites, there were only 7 cases which could be classified into Pal-kyungs(Famous 8 Sceneries) and 3 cases classified into Dongcheon(beautiful scenery surrounded by mountains and rivers), but there was no Gugok(beautiful valleys). Consequently, in terms of external appearance, the scenic sites among the total scenic sites that could be classified into Palkyung and Gugok were only 14.7%(10 cases). Fourth, the traditional scenic sites based on literal references and Internet analysis occupied 67.7%(46 cases), which were found to be scenic sites related to the traditional Pal-kyung among which 38 cases(55.9% of 46 cases) were included based on the scenery and 8 cases(11.8% of 46 cases) were included due to the scenery at the time. Fifth, there were 8(11.8%) scenic sites which were related to Dongcheon, and 4 cases(5.9%) related to Gugok. Also, it was found that total of 40(48.9%) scenic sites designated as modern scenic sites were playing the role of local scenic sites, and they were used as the tourism advertising contents. Sixth, it was identified that there were 62 cases(91.2%) of scenic sites in total related to traditional and modern Pal-kyung or Dongcheon-gugok, and unlike explicit classifications, most of the designated scenic sites were found to be deeply connected with the historical and cultural significance contained in the scenaries.

This study attempted to investigate the effects of natural henna-treated permanent wave on degree of damage and morphological changes of hair. For this, amino acid was analyzed, and hair thickness and surface were observed through SEM. In addition, hair curl formation & retention, methylene blue coloring, tensile strength and elongation were measured. The results found the followings: Total amino acid contents rose as the number of natural henna treatment increased, hair protection effects are expected. In terms of curl formation, in an experimental group hair became more elastic as the number of natural henna treatment increased, compared to a control group. In both control and experimental groups, hair retention decreased as shampooing frequency increased because of extension of (C) and (C)', According to analysis of hair thickness using SEM, hair became thick in an experimental group after natural henna treatment, compared to a control group. In morphological observation of hair surface, it was mostly clean, and cuticle was tidy and healthy. In methylene blue coloring, as the number of natural henna treatment increased, absorbance went up. In addition, tensile strength declined in an experimental group, compared to a control group. As the number of natural henna treatment increased, elongation in an experimental group increased, compared to a control group. The above results show that as the number of natural henna treatment increased, hair became thicker, and curl formation and retention improved. In addition, hair elasticity and flexibility were enhanced, reducing a risk of hair damage. Therefore, the study results would be available as basic data in reducing scalp and hair damage, proposing the natural henna treatment as a method to reduce hair damage from chemical perm in cosmetology industry.
