The halophyte Leymus chinensis (Trin.) is a perennial rhizome grass (tribe Gramineae) that is widely distributed throughout China, Mongolia and Siberia. This study was conducted to investigate an optimal condition for plant regeneration from mature seeds, leaf base segments, and root segments in L. chinensis. Plant growth regulators affecting embryogenic callus induction and plant regeneration were investigated by four-factor-three-level [L9 (34)] orthogonal test in this study. The effects of explants types (mature seeds, leaf base segments and root segments), callus types, medium types were examined in this study. Wild type (WT) and Jisheng No. 1 plants (JS) were used for primary callus induction. A clear explants difference was seen during callus induction; mature seeds were considered as the preferred explants; and the highest frequency of callus induction was obtained in Medium 6 using mature seeds as explants in WT. Plant regeneration ability was evaluated by frequencies of green callus forming, shooting, rooting, and shooting with roots. Effect of α-naphthalene acetic acid (NAA) on shoot regeneration was remarkable with the highest frequency of 70.8% in WT after 2-month culture. The medium with 0.2- 0.5 mg/L NAA was found to have the highest shoot induction. All regenerated shoots were successfully rooted when transferred on half-strength Murashige and Skoog (MS) basal medium. The acclimatized plantlets were grown to mature with flowering and seeds setting in green house conditions.

Purpose: To investigate health problems in child day care centers, needs for Child Care Health Programs, and management of sick children by day-care staff. Methods: A cross-sectional descriptive study. Day-care staff (N=206) from 33 day care centers in Seoul, completed a structured questionnaire. Results: Almost half of the day-care staff (53.4%) experienced sick events in their child at least once a month. The most frequently reported difficulty in having a sick child was in not having a health professional to consult, and almost all day-care staff (99.5%) had asked parents not to bring a sick child to the day care center. The biggest reason of exclusion was due to infectious disease including measles, chicken pox, mumps, diarrhea·vomiting, and pink eye. The majority of day-care staff (97.6%) agreed that there is a need for Center-based Child Care Health Program (CCCHP), and expected general health & illness management, and special care for chronic disease from CCCHP. Conclusion: These results showed a high incidence of sickness in children in day care centers, and there were great demands for a Center-based Child Care Health Program for day-care staff. Also the results of this study can be utilized as a basis for the establishment of child care policy in Korea.

Post-Pneumonectomy Empyema[PPE] is a relatively uncommon but serious complication. And the management of it remains a disturbing and controversial area in the field of general thoracic surgery. Many methods have described and have had varying degrees of success. For the purpose of providing the guideline for management of post-pneumonectomy empyema, we reviewed our experiences of treatment of PPE from January 1985. to December 1992. There were 17 cases, which consist 7.9% of all pneumonectomy cases for that period. There were 13 male and 4 female patients with mean age of 47.1$\pm$ 16.2 yrs old. Both chest has the same incidence. The most common disease for prior pneumonectomy was tuberculosis, but the PPE was the most frequently occurred in empyema. The duration between pneumonectomy and PPE was 44.7 $\pm$81.1 months, where 58.8% of patients occurred within 1 month. Fever was the most frequent complaint and wound dischrge was detected in less than half of patients. There were 2 in-hospital mortalities.Mostly, in 13 cases, we did Eloesser operation. Five of them could finish second Clagett procedure, but one had recurrence. Four bronchopleural fistular patients underwent 3 single stage muscle flap closure and 1 direct closure with modified Clagett procedure. None had recurrence. Mean follow-up duration is 30.9\ulcorner22.3 months. There was 1 late death which was not related to PPE but to Malignancy recurrence.

The empirical research was conducted to investigate women's consumption pattern of Korean rice cakes and to analyze the preference of them by their demographic backgrounds. The results of this study provide useful informations for a systematic development of Korean rice cake. A self-completed questionnaire survey of 281 women in Seoul was undertaken and detailed information was collected from each. A questionnaire consisted of three parts including demographic backgrounds, consumption pattern and preference of Korean rice cakes, and the need assessment. Demographic variables of respondents included age, marital status, education, family style, monthly income etc. Most of them(82.6%) were married with the average age of $36.3{\pm}8.4$ year old. The results of eating frequency rate showed that about half of women(49.1%) had Korean rice cake once or twice a month followed by once a week(23.1%), once per two months(13.9%), once per six months(8.2%), and once per three months(3.9%). Average preference score of 14 Korean rice cakes was $3.08{\pm}1.49$ out of 5, indicating 'so-and-so'. Ingeolmi received the highest score of 4.02, whereas Duteopteok had the lowest score of 0.18. The preference score of Korean rice cake and the respondents' knowledge of them showed significantly strong positive correlation. The need-assessment score for improving the quality of Korean rice cake was $3.72{\pm}1.35$ out of 5, showing moderate willingness for improvement of Korean rice cake.

This study is purposed to analyze the degree of content and wearing style of fur cloths in order for women to buy them effectively and to wear them contentedly. So scrutinized buying style and wearing condition of fur clothes. To show whether women's buying fur clothes are suitable for their body or not, this study was examined characteristics, sorts, method of fabrication and manufacture, buying pattern and trends of fur clothes. The conclusion from this study examining the degree of possession, decision making of buying and recognition of fur clothes are as followings: 1. When women wears fur clothes, style of fur clothes have nothing to do with their body and height, and women who are 150∼160cm tall content to fur clothes commonly. 2. Condition of buying fur clothes, many 40's women whose only husband earns family's bread belong to fur clothes, and buy them, talking with a husband. Also, according to income a month, and to the ind of a job, in case of a couple's earning family's bread together, women whose whose income is 800,000 to 1,000,000￦ level. 3. Condition of wearing fur clothes, the cause that women feel like wearing fur clothes is as following: economic stability their own pride, and contentment to wear them. Women want to wear those different from fur clothes that they possess, and half coat, because of working conveniently. As the above mention, purchasers recognite the conception of fur clothes for themselves, and buy economically them, and must wear those of which design and style are suitable for body.

Systemic lupus erythematosus in a dog, suspected systemic lupus erythematosus in a dog, and autoimmune thrombocytopenic purpura hemmorrhagica in a dog are reported. A fice-year old, female Chihuahua (Case 1) showed initially hemorrhagic diathesis and purpura hemorrhagica. Afterward, it showed polymyositis and polyarthritis. LE-cell was demonstrated on LE-cell preparation trom blood. Systemic lupus erythematosus was diagnosed. This reponded well to the immunosuppressants, but developed iatrogenic Cushing syndrome and steroid hepatopathy. A two-and-half-year old, male toy poodle (Case 2) had chief complaint of red urine. Occult blood test for the urine sediment. This did not respond at all to antibiotics and carbazochrome, which is one of systemic coagulants. LE-cell was demonstrated on LE-cell preparation from blood. This responded relatively well to immunosupressants such as prenisolone, azathioprine and cyclophosphamide. systemic lupus erythematosus is suspected. A nine-year-and-three-month old, female Maltese (Case 3), which had history of congestive heart failure and ovariohysterectomy showed purpura hemorrhagica in the skin of chest. This had severe thrombocytopenia and leukocytosis. As prednisolone was administered before immunological examination or demonstration of LE-cell, it was impossible to diagnose whether purpura hemorrhagica developed as a member of systemic lupus erythematosus or independent of systemic lupus erythematosus. This responded well to prednisolone, and so autoimmune thrombocytopenic purpura hemorrhagica was diagnosed.

We study an association between the duration of solar activity and characteristics of the latitude distribution of sunspots by means of center-of-latitude (COL) of sunspots observed during the period from 1878 to 2008 spanning solar cycles 12 to 23. We first calculate COL by taking the area-weighted mean latitude of sunspots for each calendar month to determine the latitudinal distribution of COL of sunspots appearing in the long and short cycles separately. The data set for the long solar cycles consists of the solar cycles 12, 13, 14, 20, and 23. The short solar cycles include the solar cycles 15, 16, 17, 18, 19, 21, and 22. We then fit a double Gaussian function to compare properties of the latitudinal distribution resulting from the two data sets. Our main findings are as follows: (1) The main component of the double Gaussian function does not show any significant change in the central position and in the full-width-at-half-maximum (FWHM), except in the amplitude. They are all centered at ~ 11° with FWHM of ~ 5°. (2) The secondary component of the double Gaussian function at higher latitudes seems to differ in that even though their width remains fixed at ~ 4°, their central position peaks at ~ 22.1° for the short cycles and at ~ 20.7° for the long cycles with quite small errors. (3) No significant correlation could be established between the duration of an individual cycle and the parameters of the double Gaussian. Finally, we conclude by briefly discussing the implications of these findings on the issue of the cycle 4 concerning a lost cycle.
