This research was performed to screen eye health status for pre-school children (4~5 age) and establish as eye health checking system m community health center. This data was collected from 1st February, 1995 to 31st October, 1995. To screen the state of their vision, the Developed Visuual Test (D.V.T) was used for pre-school children. This is used at home by their parents and then it is also used among the kindergarten health team at Jung-gu health center in Seoul. This was done with the and of Randot and Han Choun Souk tests. The total number of children who were tested was 1441. Among the children, children aged 5 were 707, and those aged 4 were 734. The results of this study were as follows; * Description of the health status for the pre-school children. 1. The rate of children average vision in both eyes, whose was below 05 by Han Choun Souk are 7.6% (age 4) and 4.8% (age 5). 2. Only 20 4% (age 5) and 30 8% (age 4) of the pre-school children had been tested through the ophthalmic department. 3. The children with a level below 05 (Han Choun Souk test) had been tested only 43% (age 4), and 12% (age 5) 4. There was no particular difficulty in understanding the D.Y.T: 13.9% (age 4), 11.6% (age 5) of the tested children had eye problems. 5. 231 cases were trichiasis, entropin, strabismus, and amblyopia. * The different visual tests. The results of the visual tests between the two groups (parents and health teams) are similar and it shows that parents can easily test at home. * Delivery system of the D.V.T questionnaire The way children's parents received the D.V.T questionnaire were carried out by two ways By mall from the community health center. Send through the institution, for example the kindergarten school The receipt rate of this D.V.T questionnaire sent through the institution was higher than sent by mall.

It is generally known that mutations in any of several genes encoding photoreceptor-specific proteins have resulted in retinitis pigmentosa (RP), a disease characterized by losing photoreceptor function with progressive degeneration of photoreceptor cells and eventually leading to blindness. To study the procure and cure of photoreceptor degeneration, we produced transgenic mice. Transgene consisted of a 12.5kb genomic DNA fragment that contains mutated pig rhodopsin gene (Pro-347-Ser) including both the 5'-franking (4.0 kb) and the 3'-franking (2.9 kb) sequences. This gene was used for the production of transgenic mouse. The mutated rhodopsin DNA was microinjected into male pronuclei of fertilized mouse (C57BL /6]) embryos. We detected transgenic animals harboring mutated rhodopsin gene by PCR and Southern blot analysis. These transgenic mice showed stable transmission of microinjected rhodopsin gene into their offspring. Therefore these animals will provide a novel approach to study the mechanism of the photoreceptor degeneration and be provided as a disease model for the treatment of the blind in human.

Recently in the Mongolian wireless marketplace, many E-commerce companies have been making considerable investments in the technological development of M-commerce, taking competitive advantage of new business possibilities offered by Internet-based wireless technologies. In the Mongolian wireless marketplace, this new mobile environment opens the door for new and exciting market opportunities in mobile services and applications. In the near future, these companies will be looking toward M-commerce services as a supplemental source of revenue in the mobile marketplace. This paper examines the roles of M-commerce in the consumers' in order to promote the consumers' loyalty in the booming M-commerce. This paper contains theory that focuses on the basic concepts of the M-commerce environment, its wireless network technologies, and its applications infrastructure. Upon searching for references to assist us in establishing a market hypothesis, we discovered that few comprehensive studies on consumer perspective and behavior related to M-commerce services actually exist in the literature. In the area of M-commerce, many companies neglect the consumer perspective, concentrating only on technological factors only when formulating their market strategies. And, due to technological blindness, many companies were not able to succeed in end-user E-commerce services. Given that fact, this paper formulates a consumer-centric research model. In order to prove the research model, we chose the survey method which allows for the collection of large amounts of data from a sizeable population in a highly economical way. Through the survey, this paper defines consumer's attitudes towards M-commerce services by identifying potential Business-to-Commerce(B2C) applications and its primary target groups in terms of gender and age, and by investigating whether consumers recognize the value proposition of M-commerce applications and services. As shown in the data analysis and results, this research concludes that M-commerce development in Mongolia is still at its infancy, and that the implementation of M-commerce depends not only on technological progress, but also on consumer attitudes and their willingness to adopt M-commerce services. As well, other complex cross-cultural factors-socially, economically, culturally, et cetera-enter strongly into the equation.

A 7-year-old neutered male Shih Tzu dog weighing 5.2 kg was presented because of severe neurological signs (paddling, unconsciousness, blindness, seizure). ECG revealed accelerated idioventricular rhythm (AIVR) with ~140 bpm ventricular rate. Based on magnetic resonance imaging (MRI) study and cerebrospinal fluid (CSF) analysis, the neurological condition was tentatively diagnosed as disseminated granulomatous meningoencephalomyelitis (GME). The neurological signs were managed with steroids, anticonvulsive drugs, diuretics and antibiotics with 20% mannitol infusion. The rhythm disturbance (AIVR) was managed with oral medication of mexiletine. Because the heart rhythms were unstable without anti-arrhythmic therapy in spite of improvement of clinical signs after emergency treatment for neurological problems, the anti-arrhythmic therapy was maintained till the neurological signs were abolished.

Kallmann's syndrome has both a general and specific connotation in describing general condition of gonadotropin-releasing hormone (GnRH) deficiency or a particular cluster of anomalies associated with primary eunuchoidism. The familial occurrence of hypogonadotropic hypogonadism associated with anosmia, color blindness, synkinesia, and mental defect is the classic Kallmann's syndrome. Interestingly, anosmia, or lack of smell, was not found in the absence of gonadal deficiency in the original study of this disorder. This disorder was found on both sexes, but the male to female ratio was 11:1, and Kallmann's syndrome is more often listed under disorders of male hypogonadism for this reason. Gross anatomy has shown disorders of the olfactory bulbs associated with Kallmann's syndrome and it was demonstrated a failure of GnRH-containing cells to migrate from the olfactory placode to the hypothalamus and preoptic area. We have experienced a case of Kallmann's syndrome which showed a hypoplasia of olfactory bulb in MRI during the workup of primary amenorrheic patient. So we report this case with a brief review of literatures.

The Wonyenaejang is equivalent to the (senile)cataract in western medicine. The word cataract is used to describe the natural lens that has turned cloudy. As the natural lens of the eye becomes cloudy, it does not allow light to pass through it. Cataracts usually start as a slight cloudiness that progressively grows more opaque. As the cataract becomes more mature(increasingly opaque and dense), the retina receives less and less light. The light that does reach the retina becomes increasingly blurred and distorted. This causes gradual impairment of vision. If left untreated, cataracts can cause needless blindness. Although there are many kinds of cataracts, a senile cataract is the most common one. We chose the oriental medicine textbooks and the oriental medicine journals that were dealing with the symptoms, etiology, and internal/external treatments. The results were as follows : 1. The main causes of this disease are weak liver and kidney, burning up of the wind and heat in the liver and gall, weak spleen and stomach. 2. As the internal treatment of the Cataract, Geegukjihwangtang is mostly prescribed. 3. As the external treatment of the Cataract, (l) In the field of medicine for external application is commonly prescribed (2) In the field of drug action, frequently used treatments are as follows. emission of the evil, alleviation of fever, removal of lump of blood, and the medicine for external applications. (3) In the field of four Qi, cold medicine is commonly prescribed. (4) In the field of five tastes, bitter/hot/sweet mdicine are commonly prescribed. (5) In the field of toxicity, non-togic medicine is commonly prescribed. (6) In the field of channel distribution, most of the medicine belong to liver channel.

Group B streptococcus (GBS) is the leading cause of neonatal morbidity and mortality. Late-onset GBS disease commonly manifests as occult bacteremia or meningitis. Approximately 50% of survivors of late-onset meningitis have long-term neurologic sequelae. Cerebrovascular complications are often associated with unfavorable clinical outcomes of GBS meningitis. There have been a few reports of cerebral infarction accompanied by GBS meningitis. We report a 29-day-old girl with severe, widespread cerebral infarction due to late-onset GBS meningitis. Isolated GBS strain from this patient was serotype III, ST-19. Currently, she has cortical blindness and significant developmental delay.

Objectives : This study aims to review randomized controlled trials on acupuncture for shoulder pain according to Jadad Scale and revised STRICTA. Methods : Seven electronic databases including PUBMED, SCOPUS, RISS were searched for randomized controlled trials (RCT) of acupuncture for shoulder pain. Results : 16 RCTs were included: 14 were published in English and 2 were published in Korean. According to Jadad scale, 15 RCTs had high quality. However, most of the studies could not meet the double blindness criteria. All RCTs meet 12.9 items on average in STRICTA. Conclusions : This systematic review shows four conclusions as follows. Traditional Chinese Medicine is often used in style of acupuncture. Spots of LI15, TE14, GB21 and LI11, stainless steel needle($0.3mm{\times}40mm$), 20 retention time, manual stimulation, $Deqi$, and 2 times a week treatment (total 12) are often used. Double-blinded clinical trials needs to be conducted. It is controversial to use minimal acupunctures on controlled groups of RCTs on acupuncture for shoulder pain. Description about practitioner's background needs clarifying.

Background: The aim of this study was to observe long-term outcomes of very low birth weight infants (VLBWIs) born between 2013 and 2014 in Korea, especially focusing on neurodevelopmental outcomes. Methods: The data were collected from Korean Neonatal Network (KNN) registry from 43 and 54 participating units in 2013 and 2014, respectively. A standardized electronic case report form containing 30 items related to long-term follow up was used after data validation. Results: Of 2,660 VLBWI, the mean gestational age and birth weight were $29^{1/7}{\pm}2^{6/7}$ weeks and $1,093{\pm}268g$ in 2013 and $29^{2/7}{\pm}2^{6/7}$ weeks and $1,125{\pm}261g$ in 2014, respectively. The post-discharge mortality rate was 1.2%-1.5%. Weight < 50th percentile was 46.5% in 2013 and 66.1% in 2014. The overall prevalence of cerebral palsy among the follow up infants was 6.2% in 2013 and 6.6% in 2014. The Bayley Scales of Infant Developmental Outcomes version II showed 14%-25% of infants had developmental delay and 3%-8% of infants in Bayley version III. For the Korean developmental screening test for infants and children, the area "Further evaluation needed" was 5%-12%. Blindness in both eyes was reported to be 0.2%-0.3%. For hearing impairment, 0.8%-1.9% showed bilateral hearing loss. Almost 50% were readmitted to hospital with respiratory illness as a leading cause. Conclusion: The overall prevalence of long-term outcomes was not largely different among the VLBWI born between 2013 and 2014. This study is the first large national data study of long-term outcomes.
