Gallbladder stones in children are not common without underlying hemolytic diseases or other risk factors like obesity. Ceftriaxone, a third generation cephalosporin, is known to make biliary precipitations that can be mistaken for biliary stones. We here report two children with biliary pseudolithiasis with different treatment modalities. One child was mistaken for symptomatic gallbladder stones and underwent elective laparoscopic cholecystectomy, while the other child, after thorough history taking on the ceftriaxone medication, was suspected of biliary pseudolithiasis and was treated conservatively. Both children had the history of usage of ceftriaxone in previous hospitals for infectious diseases. The ceftriaxone history of the first child was missed before the surgery. When gallbladder stones are found in children without any underlying diseases, specific history taking of the usage of ceftriaxone seems to be absolutely required. In this case, immediate interruption of the antibiotic could resolve the episode and avoid unnecessary surgical procedure.

Purpose: To provide baseline data for prevention and education of diabetic foot in Korea. Materials and Methods: 216 diabetic patients are included in this survey. The average age is 58.64 year old with average 9.92 years of diabetes mellitus periods. Among them, 41% used insulin injection, 42% oral medication, 14% both and 3% diet were used for their blood sugar control. The diabetic foot survey was done. Results: The survey of patients symptom and disease of their feet results: 49% had sensory decrease in their feet. Associated disease in foot were callus(15%), heel pain(10%), bunion(4%), toe deformity(2%), Tinea pedis were 9%, tingle sensation were 17%, and swelling on feet were 2%, The survey of patients privious history of foot problems are: 8% had previous operation history on their feet and 17% had history of infection on their feet, 23% had bullae history, The survey of patients prevention and education are: Those who have had more than one diabetic foot education were 45.7%, and among them 24% had routine regular foot check up. Only 5% wear special diabetic shoe and 3% had custom orthotics. Conclusion: Interests to diabetic foot care is increasing in diabetic patients in Korea. However still we need more education, and efforts for prevention. Special education and diabetic shoe is still low, The survey data could be good baseline for diabetic prevention and education.

Takji-oryego (A Review of the Five manners related to the Ministry of Finance) is a book organized by Hojo (Joseon's Ministry of Finance) and the cost and details of royal events held according to five manners. This book contained a lot of information on medicine-related rituals in the late Joseon Dynasty. Thus, it was found that the royal rituals related to medicine include not only childbirth and fertility, but also Heuljeon and Sangjeon. Through this study, the following facts were newly discovered: 1) The time of transcription was between October 1840 and October 1841. 2) Huljeon (Privilege given to save) is also related to the rise of the status of medical officials after King Sukjong. 3) According to Heuljeon, medical bureaucrats in the late Joseon Dynasty had a higher position than other technical officials. 4) The contents of reward were complementary to the existing literature. The date of death of a medical official, which was unknown in previous studies, is documented. In a case like Sansilcheong, there are contents that are unknown through other sources.

The positions of galaxies in comoving Cartesian space varies under different cosmological parameter choices, inducing a redshift-dependent scaling in the galaxy distribution. The shape of the two-point correlation of galaxies exhibits a significant redshift evolution when the galaxy sample is analyzed under a cosmology differing from the true, simulated one. In our previous works, we can made use of this geometrical distortion to constrain the values of cosmological parameters governing the expansion history of the universe. This current work is a continuation of our previous works as a strategy to constrain cosmological parameters using redshift-invariant physical quantities. We now aim to understand the redshift evolution of the full shape of the small scale, anisotropic galaxy clustering and give a firmer theoretical footing to our previous works.

Purpose: The aim of this study was to investigate the independent factors associated with the registration rate for the community-based post suicidal care program in the emergency department (ED). Methods: This prospective observational study was conducted between March and December 2013 at the academic ED at the tertiary urban hospital. During the study period, the pre-designed registry was recorded. The variables examined included the following: patients' demographic data (Sex, age, address, type of insurance, marital status, level of education, and history of previous psychiatric disease), suicide-related data (suicidal methods, combined drink of alcohol and number of previous attempts), and management-related data (disposition at ED, physician's training level, etc.). Univariated and multivariated logistic regression analyses were performed for identification of factors affecting the registration rate for the community-based post suicidal care program. Results: A total of 163 suicides were included during the study period. Of these, 33 (20.2%) patients were registered in the post-suicide care program. Factors including a patient's address (OR: 14.92, 95% CI: 3.606-61.711), immediate intervention by psychiatric healthcare center (OR: 5.05, CI: 1.688-15.134), admissions in hospital (OR: 3.69, CI: 1.286-10.605), and history of previous psychiatric disease (OR: 3.52, CI: 1.216-10.201) showed significant association with registration for the program. Conclusion: The community-based post-suicidal care program, which is available 24 hours a day, should be operated in each district in order to increase the registration rate. Emergency physicians should actively consider the inpatient treatment program for suicidal patients and strongly recommend registration to the program, particularly for patients without previous history of psychiatric disease.

Ayurveda is one of the most historic and comprehensive medical system in the world. It was passed down as Buddhist medicine with Buddhism to influence enormously to East Asian medicine. Therefore, researches on Ayurveda is important in studying East Asian medicine as well as in studying Indian traditional medicine and althernative medicine. However, in previous studies, the term, 'Ayurveda', was mistaken and misused frequently. Clarifying the relations between the definition of Ayurveda and Indian traditional medicine is essential in preventing future controversy. Therefore, such relations were studied to draw following conclusions. 1. 'Ayurveda' is the term determining the oldest medicine system in the world that originated in India. Reportedly, the first book about Ayurveda is "Agnivesha samhita", and the oldest existing book is "Charaka Samhita". No records were found on medine books named Ayurveda, and interpreting Ayurveda to be a name of a book is explicitly misunderstanding. 2. There are various divisions of Indian traditional medicine in previous studies. However, divisions in 6 types of Ayurveda, Siddha, Unani, Yoga, Naturopathy and Homoeopathy is the most proper. 3. Ayurveda gained some similarities as it exchanged with other medicine systems. However, since each medicine system has unique characteristics, they must be separately studied. Especially, current Indian traditional medicine system has many divisions. Terms of 'Indian traditional medicine' and 'Ayurveda' must be separately used.

This paper proposes a filter-based algorithm to adaptively adjust the contention window in IEEE 802.11 DCF. The proposed mechanism is focused on the general and realistic environments that have various conditions regarding to noise, media types and network load. For this flexible adaptation, Filter-based DCF(FDCF) takes a more realistic policy such as median filter concept in the image processing technologies. We can handle these various environments by adjusting the contention window size according to the result of filtering based on history-buffer. We can ignore temporarily and randomly occurred transmission failures due to noise errors and collisions in noisy environments. In addition, by changing the reference number and history-buffer size, FDCF can be extended as a general solution including previous proposed mechanism. We have confirmed that the proposed mechanism can achieve the better performance than those of previous researches in aspects of the throughput and the delay in the realistic environments.

Objectives : The aim of this study was to examine associations between quality of life in patients with schizophrenia and their family relationships. Methods : A total of 68 patients with schizophrenia participated in the study. Socio-demographic and clinical data were collected, as well as results from the Subjective Well-being under Neuroleptic Treatment Scale-Short Form(SWN-K), Family Emotional Involvement and Criticism Scale(FEICS), a visual analogue scale for evaluating the degree of perceived criticism(VAS), the Family Adaptability and Cohesion Evaluation Scale(FACES), Beck Cognitive Insight Scale(BCIS), and Rosenberg Self Esteem Scale(R-SES). Psychiatrists administered the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia(CDSS), and collected a history of previous suicide attempts. Results : The SWN-K total scores showed significant negative correlations with scores on the FEICS perceived criticism, CDSS, and VAS measures and significant positive correlations with scores on the R-SES, FACES, and BCIS. Multiple regression analysis revealed that FEICS perceived criticism, FACES, and BCIS scores were significantly associated with SWN-K scores. The FACES total score was significantly lower in patients with a history of previous suicide attempt. Conclusion : The quality of life of patients with schizophrenia was negatively associated with greater perceived familial criticism and positively associated with better family cohesion and higher patient insight. In patients with a history of suicide attempts, family adaptability and cohesion were significantly low.

Most of researches in Korea by far on Sekino Tadashi were mainly focused on his historical view only. The main observations of this study, instead, are that; (1) his methodology of studying architectural history was closely related to his previous experiences with the conservation of the architectural heritages in Japan, and (2) his earlier activities in Korea made a significant Influence on the conservation of the architectural heritages in Korea. Sekino started his carrier after the graduation from the university by participating in the restoration sites of the architectural heritages in Japan, and his experiences at that time had founded the basis of his methodology of studying architectural history. Later, his on-site experiences were also adapted into the conservation of the architectural heritages in Korea when Korea was about to be colonized by Japan. In other words, Sekino's study on the Korean traditional architectures started from 1902 had a meaning of not only the starting point of the study on the Korean architectural history but also the starting point of the conservation of the Korean architectural heritages. Especially, Sekino's study during 1909 1912 prioritized the conservation of the architectural heritages as the main purpose of the study, and the influences of the study spanned over the entire colonial period by Japan. The influences were that; (1) Sekino's studies in 1909 1912 had outlined the colonial government's policy of the conservation of the architectural heritages, and (2) many restorations were made based on those studies.

Purpose: In this study, we attempted to analyze the occupational accident experience rate by working life cycle of Korean workers considering entrance and turnover in their jobs. The specific goal of this study was to calculate the accident experience rate according to workers' turnover history and previous accident experience. Methods: We constructed a cumulative data set of 90,338 cases of workers' accident experiences in their jobs from the Fourth Korean Working Conditions Survey. The accident experience rates according to workers' turnover and previous accident experiences were analyzed using descriptive statistics and analysis of variance. Results: In this study, the cumulative accident experience rate of Korean workers was found to be 5.2%. It was confirmed that the accident experience rate of workers increased as the turnover frequencies increased. In addition, we analyzed only the data of the workers who had experienced turnover and found that the accident experience rate after turnover increased about 7.5 times when workers had experienced accidents in the past. Conclusion: To prevent occupational accidents in workers, safety strategies should consider a worker's previous job history and injury experiences. It will also be necessary to focus preventive efforts on new and young workers through ongoing monitoring and on-the-job training.
