In this paper, we analyze the quality of life of children and adolescents with cancer. Separated children and adolescents to treat more than 293 patients myeongreul quit two years to analyze the quality of life. In most previous studies it was to compare the quality of life of the patient to feel the parent to evaluate the quality of life in children and adolescents with cancer. Or It was common practice to evaluate Pediatrics as a group. However, to evaluate a wide range of ages of children and adolescents cancer patients as a basis, there is a problem. Therefore, in the paper according to the degree language understanding and 10 to 12 years old and 13-20 years old classified as two groups. In addition, we use KMMQL-AF questionnaires written in korean. Accurate across the 10 local hospital the experts have described the extraction accompanied by an in-depth interview research surveys for data collection (15.07.2011 - 01.31.2012).

A edible mushroom, Hypsizygus marmoreus is commercially cultivated. However, the researches of cultivation and physiological characteristics were not conducted in Korea. In this study, we conducted on artificial cultivation of H. marmoreus and elucidated the effect of light on the mycelial growth and fruit body development using LED light sources with different wavelength; blue (peak wave length 460nm), green(peak wave length 530nm), yellow(peak wave length 590nm), red(peak wave length 630nm), and white as positive control. Mycelial growth of H. marmoreus strains were inhibited about 30~40% in inhibition ratio under the illumination with blue, green, yellow LED light. However, red LED light was not inhibited. Elongation of stipe was effective under the long wave length such as yellow and red light. Abnormal fruit body was produced under the long wavelength and dark. However, development of pileus was effective under the short wavelength such as green and blue light. Also, as a result of cultivation with mixed light for high quality and harvest, many effective numbers and yields of fruiting bodies were obtained in the mixed treatment of blue and white light, and pileus developed well.

Chlorothalonil is continuously introduced into the marine environment and has significant toxic effects on various marine organisms, however, research on its effect on seaweed is limited. Therefore, we analyzed the impact of chlorothalonil on the early life stages of major aquaculture species in Korea, Undaria pinnatifida. U. pinnatifida female gametophytes were exposed to different concentrations of chlorothalonil (0, 0.03, 0.05, 0.10, 0.20, and 0.40 mg L^-1), and their survival rate and relative growth rate were analyzed. The no observed effect concentration (NOEC), lowest observed effect concentration (LOEC), and median lethal concentration (LC50) for female gametophyte survival were determined as 0.05, 0.10, and 0.141(0.121-0.166)mg L^-1. NOEC, LOEC, and median effective concentration (EC50) for relative growth rate were 0.10, 0.20, and 0.124 (0.119-0.131) mg L^-1. Therefore, female gametophytes of U. pinnatifida are expected to experience toxic effects at concentrations above 0.05-0.10 mg L^-1 of chlorothalonil. These research findings are anticipated to serve as crucial reference data for evaluating the effects of chlorothalonil on the health of U. pinnatifida in the early life stages.

Advanced age in Esophagectomy increases the risk of postoperative morbidity and mortality. However, the recent development of operative technique and perioperative care might have decreased the postoperative morbidity and mortality after esophagectomy. Material and Method: From March 2001 to July 2004, 174 patients underwent esophageal resection for esophageal cancer in the Center for Lung Cancer, National Cancer Center. The patients were divided into two groups : group 1 consisted of 27 patients aged 70 years or more, and group 2 consisted of 147 patients under 70 years of age. The two groups were compared according to preoperative risk factors, postoperative morbidity, operative mortality and survival. Result: The mean age was 63_4. There were 159 men. On histopathological examination, $93.1\%$ had squamous cell carcinoma. On the locations, $78.7\%$ were in mid and lower esophagus. Curative resections for esophageal cancer were possible in $162(93.1\%)$ patients. Mean hospital stay was 19.4 days with out difference between the groups. The overall postoperative morbidity were occurred in 61 patients $(35.1\%)$. The most frequent morbidity was pulmonary complication in $30(17.2\%)$. Preoperative incidence of hypertension, cardiac and pulmonary dysfunction were more common in Group I. However, there was no difference in overall postoperative morbidity, operative mortality and survival rate between the two groups. Conclusion: Esophagectomy for esophageal cancer could be carried out safely in patients over 70 years of age with satisfactory short-term results. Advanced age is no longer a risk factor for esophagectomy.

In light of the development of modern high-tech industries, where human sustainability is becoming increasingly important, anorthosite needs to be reevaluated not only for its potential as a new source of aluminum, but also as a primary resource with a wide range of industrial applications. In particular, a relatively simple chemical composition with a high CaO content and Al₂O₃/SiO₂ ratio, along with its relatively low impurity levels and chemically stable nature offers significant advantages in industrial processes. Thus, anorthosite is considered as an important industrial resource in the age of energy transition. In this review, we examine the mineralogical and geochemical characteristics of anorthosite that determines their stability and reactivity. Based on their characteristics, we propose the potential use of utilizing the anorthosite as an alternative to the Bayer process which has the limitations. We also explore its application as the eco-friendly geo-synthetic materials, and as the new materials for carbon dioxide storage and utilization. As the demand for aluminum applications accelerates, anorthosite is gaining their importance in the geological industry and clean energy field. Therefore, advanced and extensive research on anorthosite complex occurring in the Hadong and Sancheong regions of Korea is critical to obtain opportunities to enhance economic advantages through efficient utilization of national resources and to lead to sustainable development.

Purpose: The purpose of this study was to investigate the effects of a structured preoperative PCA education on the knowledge and attitude regarding PCA usage, level of pain, and the consumption of analgesics after operation for colorectal surgery patients. Methods: This study was conducted from 18 Feb to 2 May, 2008. Participants were 80 colorectal cancer patients who would use the IV-PCA after colorectal surgery in a cancer hospital in Gyeonggi-do, Korea. Two groups, experimental and control were consisted of 40 patients each. The 20-minute structured education regarding PCA usage was applied to each patient individually in the experimental group but only the routine anesthetic consultation was given to each patient in the control group the day before the surgery. The SPSS/PC 10.0 program was introduced to analyze the collected data on frequency, percentage, mean, standard deviation, $x^2$-test, t-test and paired t-test. Results: The experimental group with the structured preoperative PCA education showed higher knowledge and more positive attitudes regarding the PCA usage than the control group. Also the experimental group showed better pain control and lower consumption of analgesics at 4, 8 and 24 hours after than the control group. Conclusion: The structured preoperative PCA education is an effective nursing intervention for improving the knowledge and attitude of the colorectal surgery patients on the PCA usage, and enabling the patient to take the analgesic more effectively with lower consumption, while reducing the patients' pain after operation.

The aim of this study was to construct and test a structural equation model for the risk factors of metabolic syndrome in Korean adults. The structural equation model hypothesizes that eating alone and feeling depressed is a risk factor for metabolic syndrome. The data of this study were obtained from the Sixth Korea National Health and Nutrition Examination Survey which was cross-sectional data from the representative national survey. A total of 4,013 subjects replied to the survey item of lifestyle and completed the physical examinations among adults aged 19 years or older in South Korea was in 2015. The structural model in this study was composed of four latent variables: eating alone, depression, negative health behavior, and metabolic syndrome. Two variables, the rate of eating alone and depression, were exogenous variables. Negative health behavior was both a mediating variable and endogenous variable, and metabolic syndrome was the final endogenous variable. The data were analyzed using the Maximum Likelihood method and bootstrapping. The structural model was appropriate for the data based on the model fit indices. The results of this study can be summarized as follows: Eating alone is a direct risk factor of metabolic syndrome in Korean women. Depression can mediate metabolic syndrome through negative health behaviors. Negative health behavior had a direct impact on metabolic syndrome in both men and women. This study may be a guideline for interventions and strategies to reduce the incidence of metabolic syndrome in Korean adults.

Diagnosis using voice is non-invasive and can be implemented through various voice recording devices; therefore, it can be used as a screening or diagnostic assistant tool for laryngeal voice disease to help clinicians. The development of artificial intelligence algorithms, such as machine learning, led by the latest deep learning technology, began with a binary classification that distinguishes normal and pathological voices; consequently, it has contributed in improving the accuracy of multi-classification to classify various types of pathological voices. However, no conclusions that can be applied in the clinical field have yet been achieved. Most studies on pathological speech classification using speech have used the continuous short vowel /ah/, which is relatively easier than using continuous or running speech. However, continuous speech has the potential to derive more accurate results as additional information can be obtained from the change in the voice signal over time. In this review, explanations of terms related to artificial intelligence research, and the latest trends in machine learning and deep learning algorithms are reviewed; furthermore, the latest research results and limitations are introduced to provide future directions for researchers.

In regard to media contents of digital heritage reconstruction, they are actively produced in museums, art galleries and special exhibitions. However, there is no concrete guideline for the productions and the pipelines are not systematic either. This makes the process ineffective regarding time and cost. Media contents production of digital heritage reconstruction might seem similar to film or documentary production, but it is important to construct its specific pipeline based on its specific purpose. The digital Heritage group in research center for culture technology of KAIST produced media contents which digitally reconstructed various heritages such as Persepolis, Iranian remains, with National museum of Korea, Sukgulam, and Hue, an ancient city in Vietnam, with Cultural heritage administration of Korea. From these experiences and case studies, this paper will present a pipeline model for efficient production.
