The purpose of this study was to examine the effects of a healing garden program based on internal factors of vocational adaptation on career attitude for college students with developmental disabilities. First, healing garden program was defined by a group of experts related to education for developmental disabilities in the industry and academia through the focus group interview. Second, the healing garden program for college students with developmental disabilities was carried out for 15 weeks. Third, this study examined the effects of healing garden program based on internal factors of vocational adaptation on career attitude for college students with developmental disabilities. The participants of this study were 55 college students with developmental disabilities in N University, with 25 students placed in the experimental group and the other 30 in the control group. As a result of examination, the difference between before and after the program, it was found that factors of career attitude were improved significantly after the program in the experimental group, with Factor 1 (determination) increased from 2.08 to 3.39, Factor 2 (finality) from 2.28 to 3.19, Factor 3 (confidence) from 2.20 to 3.69, Factor 4 (preparation) from 2.12 to 3.79, and Factor 5 (independence) from 1.88 to 3.63. But the control group did not show a significant improvement after 15 weeks of the program except Factor 3 (confidence) and Factor 5 (independence). It was found that the healing garden program based on internal factors of vocational adaptation had effects on career attitude for college students with developmental disabilities. Finally, the program will contribute to vocational rehabilitation for college students with disabilities. The findings further suggest that healing gardening programs that facilitate career attitudes must be continuously developed and applied in order to establish effective transition from school to the world of vocational adaptation.

Carthamus tinctorius L. (known as safflower) is a valuable oil plant whose importance is increasing rapidly in the world due to its high adaptation to arid regions. The seeds of this unique plant are especially used in edible oil, soap, paint, varnish and lacquer production. Its flowers are used in vegetable dye production and medicinal purposes beside its features as a coloring and flavoring in food. After the oil is removed, the remaining pulp and plant parts are used as animal feed, and dry straw residues are used as fuel. Beside all these features, its usage as a herbal medicinal plants for various diseases has gained importance on recent years. In this study, it was designed a plant metabolomic approach which transfers all the recent data processing strategies of untargeted metabolomics in clinical applications to the present study. Q-TOF LC/MS-based analysis of the extracts (70% ethanol, hexane, and chloroform) for both seed and flowers was performed using a C18 column (Agilent Zorbax 1.8 µM, 100 × 2.1 mm). Differences were observed in seed and fruit extracts and these differences were visualized using principal component analysis (PCA) plots. The total number and intersections of the peaks in the extracts were visualized using peak count comparison graph. Based on the experimental results, the number of the detected peaks for seeds was higher than the ones for the flowers for all solvent systems to extract the samples.

Background: Nivolumab and pembrolizumab are antagonists of the programmed death-ligand 1 (PD-L1) receptor that function as immuno-oncological agents. This study aimed to evaluate the safety and efficacy of nivolumab and pembrolizumab in elderly patients in outpatient settings. Methods: The safety and efficacy of nivolumab and pembrolizumab were compared retrospectively among patients at the Veterans Health Service (VHS) Medical Center in Seoul, South Korea, from September 1, 2017 to August 25, 2018. Results: Eighty-seven patients were selected for the study. The median progression-free survival was 63 days for nivolumab (95% confidence interval (CI), [14 to 282]) vs. 243 days for pembrolizumab (95% CI, [22 to 348]) (p =0.04). The objective response rate (ORR) was 0% in the nivolumab group vs 5.6% in the pembrolizumab group (p =0.310). All the patients exhibited treatment-related adverse effects. More than 89% of the patients exhibited diseases of the gastrointestinal (GI) tract. Pneumonia, of grades three or higher, was the most common adverse effect, followed by weakness and anorexia. Conclusions: There was no statistically significant difference between the nivolumab group and the pembrolizumab group with respect to the ORR. The incidence and severity of the adverse effects in this study were higher than those of previous studies; however, these adverse effects are generally manageable in a real-world clinical setting. Further randomized controlled studies will be necessary to confirm these results in elderly patients.

Individual values exert strong influence on attitudes, behaviors and lifestyles of a person. Furthermore, Individual values predict personal world views and can predict behavior and behavioral predispositions in the organization. So, individual values influence the organization strongly. And, organizational culture in police is affected by the values of police officers. The aim of this study is to make use of the theory of human values developed by Rokeach as a theoretical framework to evaluate value preferences among police officers in Korea and have a thorough grasp of the point of sameness and difference with two studies. In this study, I analyze data and make a comparative study of values with preceding studies I find that police officers regard personal values as more important than social values. A noticeable finding of this study is the middle ranking of the value of equality among police officers. It's different result with other studies. And, the value of national security is the low ranking among police officers. It's the same result with preceding studies.

White blood cells (WBCs) are present in most human ejaculates, but abnormally high concentration of seminal leukocytes may reflect an underlying pathological condition. The World Health Organization (WHO) has defined leukocytospermia as status of more than $10^6$ WBC/mL of semen. The purpose of this study was firstly, to compare the outcomes between conventional IVF and ICSI in leukocytospermia, and secondly, to investigate whether ICSI may be an alternative treatment for patients with leukocytospermia. Total 121 cycles of conventional IVF and ICSI candidates underwent IVF cycles at PL Infertility Clinic. Semen Parameters including concentration, motility, morphology of spermatozoa and concentration of leukocytes were assessed from the raw ejaculates. There was no difference in sperm concentration, motility and morphology. The rates of fertilization and good embryo development from ICSI were significantly higher than those from conventional IVF in leukocytospermia (63.9% & 48.6%, respectively for ICSI group and 33.4% & 24.1%, respectively for IVF group, p<0.001). The pregnancy rate after ICSI was also higher than that from conventional IVF (34.3% vs 21.6%, p<0.05). These results indicate that the presence of seminal leukocytes ($>1\times10^6$ WBC/mL of semen) is adversely related with fertilization, embryo development and pregnancy rate. Therefore the measurement of seminal leukocytes in routine semen analysis appears to be of prognostic value with regard to male fertilizing potential. In conclusion, it is suggested that ICSI is an alternative choice of treatment for patients with leukocytospermia.

This paper describes the performance assessment test and analysis of test results on a Korean speech recognizer which recognizes Lombard effect received speech in noisy environment, as a basic performance assessment research. In the assessement test, standard speech data were first manipulated close to speech uttered in a noisy environment, and then performance assessment tests were carried out along with the assessment items (the type of noise, SNR) in two ways-one with Lombard effect received speech(LES), the other with not received(NLES). As a result, when 90% of recognition rate is set to be a recognition limit, it was achieved at 10dB SNR point with LES, while at 30dB with NLES. This 20dB of SNR difference indicates Lombard effect should be considered in real world assessment test. The type of noises didn't affect performance of recognizers in out tests. ANOVA analysis, in evaluating several kinds of recognizers, showed every assessment item affecting the recognition performance could be quantified.

The advent of high resolution products of surface wind and temperature derived by satellite data has permitted us to investigate ocean and atmosphere interaction studies in detail. Especially the Kuroshio extension region of the western North Pacific is considered to be a key area for such studies. We have constructed gridded products of surface wind/wind stress over the world ocean using satellite scatterometer (Qscat/SeaWinds), available as the Japanese Ocean Flux data sets with Use of Remote sensing Observation (J-OFURO). Using new data based on improved algorithm which have been recently delivered, we are reconstructing gridded product with higher spatial resolution. Intercomparison of this product with the previous one reveals that there are some discrepancies between them in short-period and high wind-speed ranges especially in the westerly wind region. The products are validated by not only comparisons with in-situ measurement data by mooring buoys such as TAO/TRITON in the tropical Pacific and the Kuroshio Extension Observation (KEO) buoys, but also intercomparison with numerical weather prediction model (NWPM) products (the NRA-1 and 2). Our products have much smaller mean difference in the study areas than the NWPM ones, meaning higher reliability compared with the NWPM products. Using the high resolution products together with sea surface temperature (SST) data, we examine a new type of relationship between the lower atmosphere and upper ocean in the Kuroshio Extension region. It is suggested that the spatial relation between the wind speed and SST depends upon, more or less, the surrounding oceanic condition.

This study systematically compared two hybrid deterministic/Monte Carlo transport codes, ADVANTG/MCNP and MAVRIC, in solving a difficult shielding problem for a real-world spent fuel storage cask. Both hybrid codes were developed based on the consistent adjoint driven importance sampling (CADIS) methodology but with different implementations. The dose rate distributions on the cask surface were of primary interest and their predicted results were compared with each other and with a straightforward MCNP calculation as a baseline case. Forward-Weighted CADIS was applied for optimization toward uniform statistical uncertainties for all tallies on the cask surface. Both ADVANTG/MCNP and MAVRIC achieved substantial improvements in overall computational efficiencies, especially for gamma-ray transport. Compared with the continuous-energy ADVANTG/MCNP calculations, the coarse-group MAVRIC calculations underestimated the neutron dose rates on the cask's side surface by an approximate factor of two and slightly overestimated the dose rates on the cask's top and side surfaces for fuel gamma and hardware gamma sources because of the impact of multigroup approximation. The fine-group MAVRIC calculations improved to a certain extent and the addition of continuous-energy treatment to the Monte Carlo code in the latest MAVRIC sequence greatly reduced these discrepancies. For the two continuous-energy calculations of ADVANTG/MCNP and MAVRIC, a remaining difference of approximately 30% between the neutron dose rates on the cask's side surface resulted from inconsistent use of thermal scattering treatment of hydrogen in concrete.

Nearly every country in the world now has the education of its own history in school curriculum. Although there is a difference in the nationality of each country, each has a common perception that history education is important. This is because everyone agrees that the nation's national identity is the core of its identity, and that it forms the backbone of national unity. In Korea, history textbooks were temporarily organized in selective courses and until recently were chosen as subjects of choice in the CSAT. However, despite the repeated neglect of national history education, the national sentiment should not always be neglected, and the formation of the national consensus will eventually prove to be a necessity for the Korean National University's CSAT. Despite the need for the education of Korean history, education has always been mentioned in conjunction with the word "crisis" and "stalemate". This article looks at the key issues in the history of the curriculum and the contents of history textbooks.
