  • Purpose : A universal standard of the birth weight for gestational age cannot be made since birth weight distribution varies with races, nations and eras. This report aims to establish the birth weight for gestational age patterns by sex, plurality, and parity, specific for Korean live births. Methods : The national birth certificate data of all live births in Korea from January 2000 to December 2004 were used: for live births with gestational age 24 weeks to 42 weeks (n=2,585,5160), mean birth weight, standard deviation and 10th, 25th, 75th and 90th percentile values were obtained for each gestational age group by one week increment. To establish final standard values of Korean birth weight distribution by gestational age, the finite mixture model to eliminated erroneous birth weights was used for respective gestational age. Same as above method the birth weight for gestational age standard by sex, plurality, and parity were completed. Results : The male newborns are more heavier than female during the entire gestational age. The singletons are more heavier than twin during the entire gestational age. The para 2 are more heavier than the para 1 during the entire gestational age. Korean standard was more heavier in 10th and 50th percentile than Lubchenco's standard. Alexander's standard was more heavier in 50th and 90th percentile than Korean standard. Conclusion : These birth weight for gestational age patterns by sex, plurality, and parity are similar to the other standards. I hope that for Korean infants, this curve will help clinicians in defining and managing the large for gestational age infants and also for infants with intrauterine growth retardation.

  • Purpose : For the head and neck radiotherapy, abutting photon field with electron field is frequently used for the irradiation of posterior neck when tolerable dose on spinal cord has been reached. Materials and methods : Using 6 MV X-ray and 9 MeV electron beams of Clinac1800(Varian, USA) linear accelerator, we performed film dosimetry by the X-OMAT V film of Kodak in solid water phantom according to depths(0 cm, 1.5 cm, 3 cm, 5 cm). 6 MV X-ray and 9 MeV electron(1Gy) were exposes to 8cm depth and surface(SSD 100cm) of phantom. The dose distribution to the junction line between photon($10cm{\times}10cm$ field with block) and electron($15cm{\times}15cm$ field with block) fields was also measured according to depths(0 cm, 0.5 1.5 cm, 3 cm, 5 cm). Results : At the junction line between photon and electron fields, the hot spot was developed on the side of the photon field and a cold spot was developed on that of the electron field. The hot spot in the photon side was developed at depth 1.5 cm with 7 mm width. The maximum dose of hot spot was increased to $6\%$ of reference doses in the photon field. The cold spot in the electron side was developed at all measured depths(0.5 cm-3 cm) with 1-12.5 mm widths. The decreased dose in the cold spot was $4.5-30\%$ of reference dose in the electron field. Conclusion : When we make use of abutting photon field with electron field for the treatment of head and neck cancer we should consider the hot and cold dose area in the junction of photon and electron field according to location of tumor.

  • This experimental was carried out to evaluate the clinical effects of Ophicephalus argus and Crubita moschate which have been traditionally applied to postpartum care in Korea, and compare them with the effect of Saenghwtang. Fifty Sprague-Dawley female rats weighing $250\~280$ g were divided into five groups: a normal saline-treated group (NSG), a Saenghuatang-treated group (STG), an Ophicephlus argus-treated group (OTG), and a Crubita moschate-treated group (CTG), also non-pregnant group (NPG). Except for the NPG, each extract was administered for one week to each group after delivery. We measured the WBC, RBC, serum levels of hemoglobin and hematocrit, the platelet count, serum levels of fibrinogen, albumin, thyroxine and urine levels of sodium and potassium. STG showed a significant (p<0.05) decrease of WBC count, fibrinogen content and urine levels of sodium and potassium and a significant (p<0.05) increase of RBC, hemoglobin, albumin and thyroxine in comparison with those of the NSG. OTG showed a significant (p<0.05) decrease of WBC count, fibrinogen and the significant (p<0.05) increase of albumin and thyroxine in comparison with those of the NSG. CTG showed a significant (p<0.05) increase of albumin and thyroxine in comparison with that of NSG. These results suggest that Saenghwatang is more effective than Ophicephalus argus and Crubita moschate for postpartum recuperation although they also have some effects on recuperation of deteriorative blood components after delivery. Therefore, these findings indicate that futher investigation for the other effects of Ophicephalus argus and Crubita moschate is necessary.

Ethanol Extract from Cnidium monnieri (L.) Cusson Induces G1 Cell Cycle Arrest by Regulating Akt/GSK-3β/p53 Signaling Pathways in AGS Gastric Cancer Cells (AGS 위암세포에서 Akt/GSK-3β/p53 신호경로 조절을 통한 벌사상자 에탄올 추출물의 G1 Cell Cycle Arrest 유도 효과)

  • Cnidium monnieri (L.) Cusson is distributed in China and Korea, and the fruit of C. monnieri is used as traditional Chinese medicine to treat carbuncle and pain in female genitalia. In this study, we examined the anti-proliferation and cell cycle arrest effects of ethanol extracts from C. monnieri (CME) in AGS gastric cancer cells. Our results show that CME suppressed cell proliferation and induced release of lactate dehydrogenase (LDH) in AGS cells by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay and LDH assay. Cell morphology was altered by CME in a dose-dependent manner. In order to identify the cell cycle arrest effects of CME, we investigated cell cycle analysis after CME treatment. In our results, CME induced cell cycle arrest at G1 phase. Protein kinase B (Akt) plays a major role in cell survival mechanisms such as growth, division, and metastasis. Akt protein regulates various downstream proteins such as glycogen synthase kinase-$3{\beta}$ (GSK-$3{\beta}$) and tumor protein p53 (p53). Expression levels of p-Akt, p-GSK-$3{\beta}$, p53, p21, cyclin E, and cyclin-dependent kinase 2 (CDK2) were determined by Western blot analysis. Protein levels of p-Akt, p-GSK-$3{\beta}$, and cyclin E were reduced while those of p53, p21, and p-CDK2 (T14/Y15) were elevated by CME. Moreover, treatment with CME, LY294002 (phosphoinositide 3-kinase/Akt inhibitor), BIO (GSK-$3{\beta}$ inhibitor), and Pifithrin-${\alpha}$ (p53 inhibitor) showed that cell cycle arrest effects were mediated through regulation of the Akt/GSK-$3{\beta}$/p53 signaling pathway. These results suggest that CME induces cell cycle arrest at G1 phase via the Akt/GSK-$3{\beta}$/p53 signaling pathway in AGS gastric cancer cells.

  • Background: Mixed obstructive and restrictive pattern of spirometry can not be concluded in the presence of true restrictive disorders because pure obstructive disorders can also show reduced vital capacity. However, it is not known how many patients with mixed spirometric pattern really have restrictive disorders in Korea whose pattern of pulmonary diseases is somewhat different from foreign countries. To answer this question, I performed this study and tried to answer it according to diseases in addition. Method: Test results from 413 patients who undergone both spirometry and lung volume measurements on the same visit from August 1, 1998 to July 31, 1999 were included. Spirometry data were classified as mixed obstructive-restrictive pattern when spirometry showed '$FEV_1/FVC$<70% (<65% if age$\geq$60)' and FVC<80% of predicted value'. TLC by the method of nitrogen washout was considered as gold standard to diagnose restrictive disorders in which TLC is less than 80% of predicted value. Results: Out of 404 patients who could be evaluated, 58 had mixed pattern of spirometry. 58 patients were suffered from airway diseases(39 patients) such as COPD(22 patients, 38%), asthma(11, 19%), bronchiectasis (6,10%), and sequelae of pulmonary tuberculosis(15, 26%) or other diseases(4,7%). Only 18 out of 58(31%) were confirmed to have true restrictive disorders by TLC. The proportion of true restrictive disorders was different according to diseases, 20.5%(8/39patients) in patients with airway diseases and 53.3%(8/15) with sequelae of pulmonary tuberculosis(p<0.05). Conclusion: Many patients whose spirometry showed mixed pattern didn't have restrictive disorders but had pure obstructive disorders. This was true for more patients with airway diseases. Therefore it would be prudent that lung volume be tested to diagnose restrictive disorders in patients with mixed spirometric pattern.

  • The home health care industry has grown rapidly and can be expected to continue to grow in the foreseeable future. Home health care refers to the practice of nursing applied to clients with a health condition in the clients place of residence. clients and their designated care givers are the focus at home health nursing practice. The goal of care is to initiate. manage and evaluate the resources needed to promote the clients optimal level of well-being and function. Nursing activities necessary to achieve this goal may warrant preventive maintenance and restorative emphases to prevent potential problems from developing. Many project program were suggested home health care model for Korea's health care system and policy direction for expansion and establishment of home health care .But the aim of this paper is to provide on overview for theoretical frame work in home health care. Theories and conceptual frameworks or models are important nursing because they define and guide the boundaries of professional practice and identify key nurse-patient-caregiver relationships that emerge with caring. Following is the research with an investigation of the literature review in the University of Arizona international medline database, In conclusion, are as followers: First, many nursing theorists have had a tremendous impact on nursing practice. the following highlights those nursing theorists that are particularly helpful in understanding home health care. 1. Florence Nightingale : Our earliest theoretical legacy. Nightingale's believes are reflected in basic infection control practice such as hand washing and infectious waste disposal and are key nursing interventions in home care. 2. Martha Roger's :Science of unitary human beings theory. Rorger's believed that the focus of shared. non invasive healing modelities is the human environmental field rather than direct physical care. These modelities continue to evolve as our awareness (reflecting greater diversity, faster rhythms, motions, and ways of knowing) transcends time and space, allowing individuals to get in touch with their integral nature of unbroken wholeness. On people as ever changing energy fields have special relevance in home care especially with hospice and palliative care applications. 3. Madeline Leininger's; Transcultural nursing theory. Home care nurses move through a variety of communities and often care for patients from different cultural back grounds. Therefore Leininger's work has a good that with home care because home care nursing practice is very culturally focused. 4. Dorothea Orem's : Self care deficit theory. Orem's theory views care as something to be performed by both nurses and patients. The role of the nurse is to provide education and support that help patients acquire the necessary activities to perform self-care. Orem's theory is foundational to have care because it begins to truly acknowledge the role of the patient in managing his or her own health. which is referred to as self-care. 5. Margaret Neuman's; Health as expending consciousness theory. Neuman believes that health compasses disease and reflects an underlying pattern of person-environment interaction. A key application of 'Neuman's work to home care is for nurses to understand that health and illness do not necessarily exist at opposite ends of a continuum. 6. Jean Watson's: Theory of human caring. Watson's theory of human caring in nursing proposes human caring as the moral ideal of nursing. Nurses participate human caring to protect, enhance and preserve humanity by assisting individuals to fing meaning in illness. pain and existence and to help others gain self knowledge. self control. and self healing such thinking lends richness to theory development. as well as clinical practice in home care. Second, Robin Rice : Dynamic self determination for self care. (A theoretical framework for home care) Dynamical self determination for self care can be useful to home care nurses in a variety of ways. As research tool it can be reflected in the interview process when the home visit. The home care nurse's role is that of facilitator of patient self-determination for self care through numerous strategies. including patient education and case management.

  • Biological products, such as live varicella vaccine, are composed of biological substances derived from biological organisms. It is very difficult to identify these biologics' characteristics by analysis of simple physical and chemical methods alone. So the reference material is essential in order to evaluate the quality of bilogics. The 1'st national standard for varicella live vaccine was manufactured, established in 2002 and 2003, and have been used for the manufacturer's quality control and national lot release since then. As the lack of its availability and the decrease of its stability, this study was initiated by National Institute of Food and Drug Safety Evaluation (NiFDS) in 2008 to manufacture and establish the 2nd national standard for varicella live vaccine. The candidate material was manufactured from one of domestic manufacterers and the joint research of the NiFDS and manufacturers of varicella live vaccine was conducted to estimate of the reliable virus content. In the collaborative study, 3 laboratories including NiFDS performed the virus content test more than 7 times and all assay results were statistically analyzed. The mean coefficient of variation (CV) was 1.24%, and the geometric mean titre (GMT) variation range of each laboratory was low. On the basis of the results of this study, the candidate material of 2nd national standard for varicella live vaccine was assigned a potency of 4.26 log10 pfu/0.5 mL, when reconstituted in 0.7 mL.

  • Ginseng is the English common name for the species in the genus Panax. This article gives a broad botanical review including the morphological characteristics, ecological amplitude, and the ethnobotanical aspect of the genus Panax. The species of Panax are adapted for life in rich loose soil of partially shaded forest floor with the deciduous trees such as linden, oak, maple, ash, alder, birch, beech, hickory, etc. forming the canopy. Like their associated trees, all ginsengs are deciduous. They require annual climatic changes, plenty of water in summer, and a period of dormancy in winter. The plant body of ginseng consists of an underground rhizome and an aerial shoot. The rhizome has a terminal bud, prominent leafscars and a fleshy root in some species. It is perennial. The aerial shoot is herbaceous and annual. It consists of a single slender stem with a whorl of digitately compound leaves and a terminal umbel bearing fleshy red fruits after flowering. The yearly cycle of death and renascence of the aerial shoot is a natural phenomenon in ginseng. The species of Panax occur in eastern North America and eastern Asia, including the eastern portion of the Himalayan region. Such a bicentric generic distributional pattern indicates a close floristic relationship of the eastern sides of two great continental masses in the northern hemisphere. It is well documented that genera with this type of disjunct distribution are of great antiquity. Many of them have fossil remains in Tertiary deposits. In this respect, the species of Panax may be regarded as living fossils. The distribution of the species, and the center of morphological diversification are explained with maps and other illustrations. Chemical constituents confirm the conclusion derived from morphological characters that eastern Asia is the center of species concentration of Panax. In eastern North America two species occur between longitude $70^{\circ}-97^{\circ}$ Wand latitude $34^{\circ}-47^{\circ}$ N. In eastern Asia the range of the genus extends from longitude $85^{\circ}$ E in Nepal to $140^{\circ}$ E in Japan, and from latitude $22^{\circ}$ N in the hills of Tonkin of North Vietnam to $48^{\circ}$ N in eastern Siberia. The species in eastern North America all have fleshy roots, and many of the species in eastern Asia have creeping stolons with enlarged nodes or stout horizontal rhizomes as storage organs in place of fleshy roots. People living in close harmony with nature in the homeland of various species of Panax have used the stout rhizomes or the fleshy roots of different wild forms of ginseng for medicine since time immemorial. Those who live in the center morphological diversity are specific both in the application of names for the identification of species in their communication and in the use of different roots as remedies to relieve pain, to cure diseases, or to correct physiological disorders. Now, natural resources of wild plants with medicinal virtue are extremely limited. In order to meet the market demand, three species have been intensively cultivated in limited areas. These species are American ginseng (P. quinquefolius) in northeastern United States, ginseng (P. ginseng) in northeastern Asia, particularly in Korea, and Sanchi (P. wangianus) in southwestern China, especially in Yunnan. At present hybridization and selection for better quality, higher yield, and more effective chemical contents have not received due attention in ginseng culture. Proper steps in this direction should be taken immediately, so that our generation may create a richer legacy to hand down to the future. Meanwhile, all wild plants of all species in all lands should be declared as endangered taxa, and they should be protected from further uprooting so that a. fuller gene pool may be conserved for the. genus Panax.

  • There are various understandings how to define death. In the context of medicine, death is defined as the irreversible change of the tissue according to the cessation of circulation and respiration. According to the psychologists, a person need to accept the finiteness as a human being and remain conscious that the death is not avoidable. And they say if a person doesn't regard death as unavoidable reality of life he or she will not confront the humanistic death and after all will die like animals. In philosophy, death is viewed as an unwelcome reality in the end of the journey of life. Sociologists usually understand that the society is the organization composed with living persons and human beings which construct and transmit the culture from generation to generation between the both ends of life and death. In society, the generation is changed, maintained, and developed through the phenomenon of death. Although death of human being is natural event in society, the death of a specific person brings a sense of loss, crisis, and anxiety to the communities like family, regional society, nation, and the world. In this context, death is not confined to personal dimension and it can be regarded as a social problem. It is valuable to summarize the religious perspectives on the meaning of death for the better hospice care. In shamanism, there are basic idea that although the flesh of human being disappears, soul never die. If human dies, the flesh of human being disappears but soul never disappear and come back to the origin of soul as it is called chaos. So in shamanism, it is said that shaman can solve the mortified feeling, restore the broken harmony, send the soul to comfortable space- the origin, and guarantee the blessing of descendents. Buddhists regard the death as an essential component through the cycles of life. Through this cycle, human being exits as an endlessly transmigrating being and the death is just a restoration to the original status. In Confucianism, the view on the death based on the philosophy of the "Yin and Yang" and "Five elements". In Buddhist tradition, many believers said the philosophy of "Death is the same as life". Unlike usual thoughts that a god governs "life and death" and "fortune and misfortune", Confucianists deny the governance of a god and emphasize the natural orders in which every phenomenon in the world moves according to the principle. Confucianists understand the death as a natural order with this principle. In Confucianists' belief, the essence of human being remains in their own descendent's lives after the death of ancestor, so in Confucianism there is no concept of immortality of the soul. In the history of Christianity, death has been defined generally as the separation of the immortal soul from the mortal body. In the earlier days of Old Testament, the death is regarded as a disappearance of just a flesh and human never disappear and always live in the relationship with God. Later days in Old Testament, we can find the growing concern for the life after the death because of the entrance of the theodicy. In the New Testament, the death is not regarded as the normal process of the human life and regarded as the abnormal status in which death come to human because of sin as a decisive factor and it should be conquered. In fact, the most of us afraid death because not of the fear of death itself but of the sense of the emptiness and regrets. so many people often make the monument hoping to live forever. But Christian usually regard this behavior as a sinful act because human being usually think themselves as a master of their life and attempt to become immortal in this kind of trial mortal. But if we live with God, we cannot confront such a condition because we aware limits as a mortal human being and entrust everything on Him and want to live according to His guidance. Therefore, in the Christian tradition, the death is regarded as accomplishment of life, fruits of life, invitation to the eternal life, and the last stage of human growth. For human being, the death is the great step of maturation as a human in the final stage of life.

  • Objectives:As increasing number of new antidepressants have been being introduced in clinical practice, pharmacological understanding has been broadened. These changes mandate new information and theories to be incorporated into the treatment process of children with depressive disorders. In light of newly coming knowledge, this review intended to recapitulate the characteristics of new antidepressants and to consider the pivotal issues to develope guidelines for the treatment of depression in childhood and adolescence. Methods:Searching the Pub-Med online database for the articles with the key words of 'new', 'antidepressants' and 'children' ninety-seven headings of review articles were obtained. The author selected the articles of pertinent subjects in terms of either treatment guideline or psychopharmacology of new antidepressants. When required, articles about the clinical effectiveness of individual antidepressants were separatedly searched. In addition, the safety information of new antidepressants was acquired by browsing the official sites of the United States Food and Drugs Administration and Department of Health and Human Services. Results:1) For the clinical course, treatment phase, and treatment outcome, the reviews or treatment guidelines adopted the information from adult treatment guidelines. 2) Systematic and critical reviews unambiguously concluded that selective serotonin reuptake inhibitors(SSRIs) excelled tricyclic antidepressants( TCAs) for both efficacy and side effect profiles, and were recommend for the first-line choice for the treatment of children with depressive disorders. 3) New antidepressants generally lacked treatment experiences and randomized controlled clinical trials. 4) SSRIs and other new antidepressants, when used together, might result in pharmacokinetic and/or pharmacodynamic drug-to-drug interaction. 5) The difference of the clinical effectiveness of antidepressants between children and adults should be addressed from developmental aspects, which required further evidence. Conclusion:Treatment guidelines for the pharmacological treatment of childhood and adolescence depression could be constructed on the basis of clinical trial findings and practical experiences. Treatment guidelines are to best serve as the frame of reference for a clinician to make reasonable decisions for a particular therapeutic situation. In order to fulfill this role, guidelines should be updated as soon as new research data become available.
