Purpose : There is growing use of continuous renal replacement therapy(CRRT) for pediatric patients, but reports about the use and outcome of CRRT in children is rare in Korea. We report our experiences of CRRT in critically ill pediatric patients. Methods : We reviewed the medical records of 23 pediatric patients who underwent CRRT at Asan Medical Center between May 2001 and May 2004. We evaluated underlying diseases, clinical features, treatment courses, CRRT modalities and outcomes. Results : Ages ranged from three days to 16 years with a median of five years. Patients weighed 2.4 to 63.9 kg(median 23.0 kg; 10 patients ${\leq}20kg$). The underlying diseases were malignancy(nine cases), multiple organ dysfunction syndrome(five cases), hyperammonemia(four cases), acute renal failure associated with liver failure(three cases), dilated cardiomyopathy(one case) and congenital nephrotic syndrome(one case). Pediatric Risk of Mortality(PRISM) III score was $17.6{\pm}7.6$ and the mean number of failing organs was $3.0{\pm}1.7$. Duration of CRRT was one to 27 days(median : nine days). Eleven patients(47.8%) survived. Chronic renal failure developed in two cases, intracranial hemorrhage in one case, and chylothorax in one case among the survivors. PRISM III score and the number of vasopressor before the start of CRRT was significantly lower in the survivors($12.7{\pm}4.2$ and $0.9{\pm}1.1$) compared with nonsurvivors($22.1{\pm}7.8$ and $2.4{\pm}1.4$)(P<0.05). Conclusion : CRRT driven in venovenous mode is an effective and safe method of renal support for critically-ill infants and children to control fluid balance and metabolic derangement. Survival is affected by PRISM III score and the number of vasopressors at the initiation of CRRT.

Psychiatrists who treat violent or potentially violent patients may be sue for failure to control aggressive outpatients and for the discharge of violent inpatients. Psychiatrists may be sued for failing to protect society from the violent acts of their patients if it was reasonable for the psychiatrists to have known or should have known about the patient's violent tendencies and if the psychiatrists could have done something that could have safeguarded in public. The courts of a number of jurisdictions have imposed a duty to protect the potential victims of a third party on persons or institutions with a special relationship to that party. In the landmark case of Tarasoff v Regents of University of California, the California Supreme Court held that the special relationship between a psychotherapist and a patient imposes on the therapist a duty to act reasonably to protect the foreseeable victims of the patient. Under Tarasoff, when a therapist has determined, or under applicable professional standards should determine, that a patient poses a serious threat of violence to another, he incurs an obligation to use reasonable care to protect the intended victim against such danger. In addition to a Tarasoff type of action based on a duty to warn or protect foreseeable victims of psychiatric outpatients, courts have also imposed liability on mental health care providers based on their custody of patients known to have violent propensities. The legal duty in such a case has been stated to be that where the course of treatment of a mental patient involves an exercise of "control" over him by a physician who knows or should know that the patient is likely to cause bodily harm to others, an independent duty arises from that relationship and falls on the physician to exercise that control with such reasonable care as to prevent harm to others at the hands of the patient. After going through a period of transition, from McIntosh, Thompson and Brady case, finally, the narrow rule of requiring a specific or foreseeable threat of violence against a specific or identifiable victim is the standard threshold or trigger element in the majority of states. Judgements on these kinds of cases are not enough yet in Korea, so that it may be too early to try find principles in these cases, however it is hardly wrong to read the same reasons of Tarasoff in the judgements of Korea district courts. To specific, whether a psychiatric institute was liable for violent behavior toward others depends upon the patients conditions, circumstances and the extent of the danger the patients poses to others; in short, the foreseeability of a specific or identifiable victim. In this context if a patient exhibit strong violent behavior toward others, constant observation should be required. Negligence has been found not exist, however, when a patient abruptly and unexpectedly attack others or unidentifiable victim. And the standard of conduct that is required to meet the obligation of "due care" is based on what the "reasonable practitioner" would do in like circumstances. The standard is not one of excellence or superior practice; it only requires that the physician exercise that degree of skill and care that would be expected of the average qualified practitioner practicing under like circumstances. All these principles have been established in cases of the U.S.A and Japan. In this article you can find the reasons which you can use for psychotherapist's liability for failure to protect third person in Korea as practitioner.

Generally the Myasthenia Gravis is classified into two of hereditary factor and acquement. Aquired Myasthenia Gravis was Quite well known to be caused by the autoimmune mechanism. Not in accurateness, on the hereditary, acetylcholine receptor antibody was to be analyzed very high in their parents and brothers. Also Myasthenia Gravis is a chronic disease characterized by voluntary muscle weakness and fatigue. above all, ocular Myasthenia Gravis is characterized clinically by blepharoptosis and external ophthalmoplegia and to be showed abut 90% cases and so oriental medicine can not but deal with myasthenia gravis at blepharoptosis. Accordinglv 20 out patients with Myasthenia Gravis were clinical study and observation as to the sex, age, progress state of MG, blood type, history, main symptom, liking for warm and cool food and tepidity, state of pulse, treatment of acupuncture and administration of oriental medicine etc. The results were as follows. 1. There was investigaed on the frequency of attack for sex, age, oculus dexter, oculus sinister, oculus uterque. Among the 20 patients, the number of female were 60% with 12 cases and male were 40% with 8 cases, therefore it was the rate of 6 : 4. the patients under 10 ages and 40 ages were 20% with 4 cases, 10 ages and 50 ages were 15% with 3 cases, 20, 30, 60 ages were 10% with 2 cases. And then oculus uterque was 90% with 18 cases, oculus sinister was 10% with 2 cases and oculus dexter were none of them. 2. Stage I were 50% with 10 patients, stage $II_A$ were 30% with 6 patients and stage $II_B$ were 20% with 4 patients, on the clinical stage and too class I were 20% with 4, class II were 45% with 9, class III were 35% with 7, in the functional activity the patients with chest heavy were 15% with 3 and hyperthyroidism were 10% with 2. 3. Hospital which patients had used to before came to this hospital were 10 university hospital and 6 local clinic. 4. The duration of disease was from 3 months to 30 years, the patients suffering between 3 months and within 1 year were 25% with 5 cases, 1-2 years were 30% with 6 cases, therefore within 2 years were 55%. 4-5 years were 15%, over 7 years were appeared less than 10%. 5. In the main symptom, all of patients were appeared to be heavy in opening their eyes the patients with blephroptosis were 70% with 14 cases on the oculus uterque, oculus sinisterf and oculus dexter, there were 20% with 4 eases each other in the oculogyation incomplete. visual failing, ophthalmoxerosis, strabismus etc and indigetion, frequency of urine(feel hurt), mild stools(or diarrea), oversensitiveness etc. but in addition, all of the other were 10%. 6. In the distribution of blood type, 0 types were 45% with 9 cases, A types were 25% with 5 cases, B and AB types were 15% each other. 7. For the rates of patients of liking for warm and cool food or tepidity, patients of liking for warm food possess 45% with 9 cases, and cool food possess 35% with 7 and tepidity possess 20% with 4, and then most of patients liking for warm food were females and cool food were much more males than females. 8. Hyunsae(弦細) were 40% with 8 cases, Buhurl(浮滑) were 20% with 4 cases, Hyunsak(弦數) were 15% with 3 cases, and in addition, the others were 10%, among 7 types of pulses. 9. The patients with less than 1 week were 40% with 8 cases, and there were female most of them and over 4 weeks were 20% and 1-2weeks were 15%, in the duration acupuncture treatment. 10. 15 kinds of prescriptions were administrated with oriental medicine from 1 week to 20weeks 1_2 weeks were 25.71% with 9 cases, 3 weeks were 17.14% with 6 cases and 6 weeks were 11.42% with 4 cases and also Gamibaetaugunbitang(加味培土健脾湯) were 28.57% with 10 cases, Gamijeounyongtang(加味正容湯) were 14.28% with 5 cases, Gamibojoongyigitung (加味補中益氣湯), Gamiyinsamyangyoungtung (加味人蔘養榮湯) were 8.57% with 3 cases each other and also Gamisamgitung (加味蔘?湯), Gamisamuloajatung(加味四物五子湯) Gamigoudungum (加味鉤藤飮), etc were applied.

This article discusses the nutritional requirements, reviews senior or geriatric dog nutritional evaluation, and then addresses some common nutrition-related problems in older dogs. The purpose of this study was to investigate the Physiologic change associated with aging, essential nutrients and their diseases in senior or geriatric dog subjects. According to a 2002 market research, 30% to 40% of dogs raisedin the United States are 7 years of age. In Europe the number of dogs considered to be "senior or geriatric" (>7 years of age) increased by approximately 50% between 1983 and 1995. A 2012 e-mail survey of 50,347 respondents revealed that 33.2% of dogs were 6 to 10 years of age and 14.7% were older than 11 years in the United States. The average life expectancy of dogs raised in the home is affected by health care, aging and nutrition.And, the aging process is influenced by breed size, genetics, nutrition, environment, and other factors. Although many pets remain active and youthful well into their teens, most dogs start to slow down and may show signs of aging beginning as early as 5 or 6 years of age. Improvements in the control of various diseases and in the nutrition of dogs have resulted in a gradual increase in the average lifespan of companion dogs. Nutritional goals for aging dogs include supporting health and vitality, preventing the onset or slowing the progression of age-related health disorders, and enhancing the dog's quality of life and, if possible, life expectancy. Aging brings with its physiologicchanges. Some changes are obvious, such as whitening of hair, a general decline in body and coat condition, and failing senses including sight and hearing. Other changes are less obvious, however, and these include alterations in the physiology of the digestive tract, immune system, kidneys, and other organs. Nutritional requirements can change with age. In addition, many diseases common in older dogs may be nutrient-sensitive, meaning that diet can play an important role in the management of the condition.

This study investigates the methods for deriving colors which can serve as a reference to users such as designers and or contents creators who search for online images from the web portal sites using specific words for color planning and more. Two experiments were conducted in order to accomplish this. Digital scenery photos within the geographic scope of Korea were downloaded from web portal sites, and those photos were studied to find out what colors were used to describe daytime and nighttime. Machine learning was used as the study methodology to classify colors in daytime and nighttime, and KSCA was used to derive the color frequency of daytime and nighttime photos and to compare and analyze the two results. The results of classifying the colors of daytime and nighttime photos using machine learning show that, when classifying the colors by 51~100%, the area of daytime colors was approximately 2.45 times greater than that of nighttime colors. The colors of the daytime class were distributed by brightness with white as its center, while that of the nighttime class was distributed with black as its center. Colors that accounted for over 70% of the daytime class were 647, those over 70% of the nighttime class were 252, and the rest (31-69%) were 101. The number of colors in the middle area was low, while other colors were classified relatively clearly into day and night. The resulting color distributions in the daytime and nighttime classes were able to provide the borderline color values of the two classes that are classified by brightness. As a result of analyzing the frequency of digital photos using KSCA, colors around yellow were expressed in generally bright daytime photos, while colors around blue value were expressed in dark night photos. For frequency of daytime photos, colors on the upper 40% had low chroma, almost being achromatic. Also, colors that are close to white and black showed the highest frequency, indicating a large difference in brightness. Meanwhile, for colors with frequency from top 5 to 10, yellow green was expressed darkly, and navy blue was expressed brightly, partially composing a complex harmony. When examining the color band, various colors, brightness, and chroma including light blue, achromatic colors, and warm colors were shown, failing to compose a generally harmonious arrangement of colors. For the frequency of nighttime photos, colors in approximately the upper 50% are dark colors with a brightness value of 2 (Munsell signal). In comparison, the brightness of middle frequency (50-80%) is relatively higher (brightness values of 3-4), and the brightness difference of various colors was large in the lower 20%. Colors that are not cool colors could be found intermittently in the lower 8% of frequency. When examining the color band, there was a general harmonious arrangement of colors centered on navy blue. As the results of conducting the experiment using two methods in this study, machine learning could classify colors into two or more classes, and could evaluate how close an image was with certain colors to a certain class. This method cannot be used if an image cannot be classified into a certain class. The result of such color distribution would serve as a reference when determining how close a certain color is to one of the two classes when the color is used as a dominant color in the base or background color of a certain design. Also, when dividing the analyzed images into several classes, even colors that have not been used in the analyzed image can be determined to find out how close they are to a certain class according to the color distribution properties of each class. Nevertheless, the results cannot be used to find out whether a specific color was used in the class and by how much it was used. To investigate such an issue, frequency analysis was conducted using KSCA. The color frequency could be measured within the range of images used in the experiment. The resulting values of color distribution and frequency from this study would serve as references for color planning of digital design regarding natural scenery in the geographic scope of Korea. Also, the two experiments are meaningful attempts for searching the methods for deriving colors that can be a useful reference among numerous images for content creator users of the relevant field.
