Meningioangiomatosis (MA) is a rare congenital tumor that occurs mostly in 5-15 year old children. There have been only 5 cases previously reported that described the cystic nature within these tumors. We present a case of a MA accompanied by a separate macrocyst. A normally developed 2 year-old female patient presented with partial and generalized seizures. The brain computerized tomogram and magnetic resonance imaging revealed the presence of a calcified mass accompanied by a cyst in the right parietal area, surrounded by low density and high attenuation edema and hemorrhage. Upon right parietal craniotomy, a $1.6cm{\times}1.2cm{\times}0.5cm$ sized plate-like, gray-white, slightly hard mass was seen and it was completely excised. Approximately 1 cm from the mass in the anterior lateral direction, a cyst was found and subsequent biopsy of the cyst wall revealed no tumor tissue, and therefore the cyst was not removed. Pathologic report demonstrated the meningioangiomatosis. Follow up examination 2 years later showed no recurrence of the tumor, and there was no evidence of neurological deficits. Authors suggest that cysts that arise in the surrounding tissues of tumors may not be tumor cysts, and do not require surgical removal.

An apparent life-threatening event (ALTE) is defined as the combination of clinical presentations such as apnea, marked change in skin and muscle tone, gagging, or choking. It is a frightening event, and it predominantly occurs during infancy at a mean age of 1-3 months. The causes of ALTE are categorized into problems that are: gastrointestinal (50%), neurological (30%), respiratory (20%), cardiovascular (5%), metabolic and endocrine (2%-5%), or others such as child abuse. Up to 50% of ALTEs are idiopathic, where the cause cannot be diagnosed. Infants with an ALTE are often asymptomatic at hospital and there is no standard workup protocol for ALTE. Therefore, a detailed initial history and physical examination are important to determine the extent of the medical evaluation and treatment. Regardless of the cause of an ALTE, all infants with an ALTE should require hospitalization and continuous cardiorespiratory monitoring and evaluation for at least 24 hours. The natural course of ALTEs has seemed benign, and the outcome is generally associated with the affected infants' underlying disease. In conclusion, systemic diagnostic evaluation and adequate treatment increases the survival and quality of life for most affected infants.

Persona means the mask of personality where the internal ego exposes itself to the outside. The complicated structure and diversity of contemporary society has provided men with a more variegated and diversified persona; in addition, advancements in internet and information communications creates the possibility for the emergence of more variegated and new persona. This study probes the persona of virtual space expressed in fashion designs; subsequently, this study reviews the concept and various characteristics of persona and examines the type of persona in the virtual space from the perspective of the manifestation of identity. The type of persona in the virtual space canbe categorized into flexible identity and falsified identity; subsequently, the characteristics and meanings of virtual space persona in fashion designs are analyzed. Flexible identity-oriented personas expressed in fashion designs are revealed through the images of animals or dolls. This is a childlike persona expression that expresses ego through other substances in an effort to express infantile substances such as dreams and fantasy cherished in childhood. Falsified identity-oriented personas are expanded as a realm of expression of the body and the realities are camouflaged as transformed persona. Negating existence itself by covering the eyes or face as well as the concealment of the body with masks or veils is an expression of a self-denying persona.

I researched clinically one patient with Hypothyroidism who was hospitalized in DongShin Univ Shunchun Oriental Hosp. from the 4th, November, 2000 to the 13th, December, 2000. The results were obtained as follows. 1. Hypothyroidism corresponds to edema of instep (浮腫), consumption (虛勞), infantile retardation of walking (行遲), retardation in speech (語遲), inactivity of Yang-Qi(결양증). It is caused to deficiency of both Qi and blood (氣血兩虛), insufficiency of Yang of the spleen and kidneys (脾腎陽虛), decline of the fire from the vital gate (命門火衰), deficiency of yang of the heart and kidneys (心腎陽虛) 2. In internal medication, it was thought that Yi qi bu xue tang(益氣補血湯). Shao yin ren Bu zhong yi qi tang(少陰人補中益氣湯), Jia wei ta bu tang (加味大補湯) were effective. 3. In acupunture therapy, zu san li(足三里), san yin jiao(三陰交), Ren ying (人迎), Fu tu (扶突), Tian tu(天突) were used frequently and in moxibustion therapy. qi hai(氣海), zhong wan(中脘). Guan yun(關元) were used for Hypothyroidism.

The role of enteropathogenic Escherichia coli(EPEC) was evaluated in a group of children with endemic diarrhea admitted to Hanyang University Hospital in Seoul, Korea. EPEC was detected in fecal samples of 23% of 100 cases and 4.5% of 44 concurrent control children. The most commonly isolated EPBC strains were serogroups $O_{18a}O_{18c}:K_{77},\;O_{86a}:K_{61},\;O_{119}:K_{69},\;and\;O_{128}:K_{70}$. On testing for enterotoxin production, 6(26%) strains were isolated from 17% of the 100 diarrheal children and in 4.5% of the 44 well controls(P<0.05). Our study supports the concept that EPEC may be an important cause of endemic diarrheas in Korea.

The purpose of the study is to construct a life table for population. It is based on the fraction of last year of life, $a_X$. The data necessary for this purpose have been obtained from the 1975 Population Census Report of Korea and the Vital Statistics of Shindong-myon, Chunseong-gun, Gangwon Province which is collected for the Seoul National University public health program. Age specific death rate is adapted by the Model Life Table, West, Level 21. For the age groups of less than 5 years of age, when the record of vital events can be obtained, the fractions are calculated from the community vital statistics. And for the age groups older than 5 years of age, Greville's Method is used. The findings are summarized as follows: 1) The fraction of last year of life in infantile group is 0.3684 for males, 0.3711 for females, and in 1-4 years of age group 1.2164 for males, 1.2274 for females. Both are more than those of Japan and U.S. in 1963. 2) Infant mortality rate is 42.37 for males, 31.77 for females per 1,000 live births. 3) The mortality curves show that a higher rate is observed under 1 year of age. It drops to the lowest point at around 10 years of age and rises again as the age increases. 4) The age estimated half-survival rate is during the age group of 70-74 for both sexes. 5) Life expectancy at the age of 0 shows 65.73 years for males and 69.22 years for females.

Robots, games and life applications have been developed while computer areas are developed. Moreover, various applications have been utilized for various users including the early childhood. Recently, smart phones have been dramatically used by various users including early childhood. Many applications need to find a path from a starting point to destinations. For example, without using real maps, users can find the direct paths for the destinations in realtime. Specifically, path exploration in game programs is so important to have accurate results. Nowadays, with these techniques, diverse applications for educations of early childhood have been developed. To deal with the functions, necessity of efficient path search programs with high accuracy becomes much higher. In this paper, we design and develop a friendly maze program for early childhood based on a path searching algorithm. Basically, the path of lineal distance from a starting location to destination is considered. Moreover, weight values are calculated by considering heuristic weighted h(x). In our approach, A* algorithm searches the path considering weight values. Moreover, we utilize depth first search approach instead of breadth first search in order to reduce the search space. so it is proper to use A* algorithm in finding efficient paths although it is not optimized paths.

Infantile osteomyelitis is a rare disease that is infective in nature and may rapidly turn fatal, as the disease is often misdiagnosed due to its varied presenting signs. Early diagnosis may help in avoiding systemic involvement and permanent deformity. The disease presents with signs of orbital involvement, nasal congestion, and emesis, as well as other standard hallmarks of infection. Furthermore, the maxilla is a highly vascular and porous bone and the occurrence of osteomyelitis in an infant maxilla is highly uncommon. In addition, routine blood work is not suggestive of the presence of this disease. Thus, prompt diagnosis of this condition poses a challenge to surgeons due to the confusing array of symptoms combined with the rarity of the disease. One such case of osteomyelitis of the maxilla in a young child is presented. The dilemma encountered by the surgeon during the diagnosis and treatment of the disease is discussed.

Glutaric aciduria type 1 (GA1; OMIM #231670) is a rare autosomal recessive inherited neurometabolic disorder caused by the deficiency of glutaryl-CoA dehydrogenase. Infantile-onset GA1 is the most common form characterized by striatal injury and progressive movement disorder, and it is often triggered by an acute encephalopathic crisis within the first three years of life. Once this crisis occurs, there is a high likelihood for ineffective or limited conventional interventions, neurological disorders, or even death. Therefore, early diagnosis and immediate preventive management, such as dietary therapy, is essential. In the past decades, newborn screening (NBS) by tandem mass spectrometry for GA1 has been largely introduced in many countries including Korea, and it has led to improvements in the neurological outcomes of patients with GA1. In this review, the clinical symptoms, natural histories, and outcomes before and after the introduction of NBS in patients are discussed.
