제주도 유용 해조류 갈래곰보(Meristotheca papulosa) 야외개체군의 생장과 성숙
김보연,최한길,고준철 한국수산과학회 2019 한국수산과학회지 Vol.52 No.1
The growth and maturation pattern of a commercial and endemic red algae Meristotheca papulosa were investigated in Jeju Island. Ecological researches were performed in a natural population of 10 m water depth in Sinheung from march 2014 to November 2015. Maximal blade length and weight of M. papulosa were 8.7 cm and 5.49 g in July 2014 and 10.7 cm and 10.17 g in September 2015, respectively. Growth in blade area of the species reached a maximum of 43.84 cm2 and 67.41 cm2 in July 2014 and 2015, respectively. Thalli in the field population were rarely observed from October to December but new recruits were found from January, following year. Carposporophytes were observed from June to September when bottom seawater temperatures were around 20℃. At the study site, seawater temperature was in the range of 14.9-25.7℃. Growth parameters of M. papulosa and relative abundance of carposporophytes showed significant correlation with environmental factors (temperature, salinity, DIN). In this result, we clarified the growth and maturation period of M. palpulosa, and provided effective data on the protection and management of natural populations and basic data for mass culture of the alga.

The authors studied insight in order to investigate its relationships to psychopathology and drug compliance in the schizophrenic patients. The subjects were 60, acutely and subacutery hospitalized patients who had relapsed more than one time. A measure of insight reflecting patients’ recognition of their illness and need for treatment was revalidated against ratings from a semistructured interview after translation and modification of the original questionnaire of McEvoy et als(19811989). The measure of drug compliance was performed by the use of original method of Van Puttens(1974). Degree of insight was consistently related to the degree of drug compliance but not severity of acute psychopathology. Nor did changes in insight during hospitalization vary consistently with changes in acute psychopathology. After running mutiple regression to see the effect of the explanatory variable including demographic variable, psychopathology and drug compliance to insight it was revealed that only drug compliance was the reponse variable in equation which had explanatory power with 8% and 23% each time. The authors discussed the possibility of existence of other variable such as socialization after admission which might explain insight on the other aspects. The authors also dicussed that the impairment of cognitive function might be reponsible for poor insight in schizophrenia. As a result these data suggest that only little of the deficiency in insight in schizophrenic patients is explanable on the basis of psychopathologic feature.

Appraising an image of a city, we first consider a street landscape, which depends on its shape and colors and so on outside colors of building are affected by features of location and symbolic meanings in buildings. Therefore, A purpose of this study is to realize we have any need to plan colors of buildings to make a beautiful street of a city and to search for Jeju landscape. The procedure to satisfy the purpose is as following : First, I studied a theory of colors, Second after choosing Top-Dong as a place to have JeJu peculiar characters. I surveyed the present condition of colors on the street and analyzed it to see if there are problems on it. Third, I suggested better alternatives by looking up Jeju peculiar colors, based on studies in the reference. It is expected that this study helps an appropriate plan of environmental colors improve the identity of the area.

본 연구의 목적은 통합교육 경험이 있는 일반유아 어머니를 대상으로 통합교육에 대한 교육환경 요구를 알아보는 데 있다. 경기교육청 산하 교육기관 중 13개소 유아교육기관(국·공립 7개소, 사립 6개소)의 243명이 설문에 응답하였다. 자료를 분석하기 위하여 기술통계 분석(항목별 빈도, 백분율)을 실시하였다. 이와 같은 방법으로 분석한 결론은 다음과 같다. 통합교육 경험이 있는 일반유아 어머니의 통합교육에 대한 태도는 긍정적으로 받아들이고 있었으며 요구하는 교육환경(교육형태, 학급형태, 실행방법, 교사조건, 정부지원, 부모교육)은 어머니의 나이, 직업형태, 학력, 자녀의 통합교육 경험 기간에 따라 차이가 있는 것으로 나타났다. This research aims to investigate perception of the educational environment perceived by the mother of kindergartener inclusion experience. For this aim, a survey was conducted to 243 mother of kindergartener of 13 kindergarten. Mother of kindergartener agreed to inclusion and were most educational environment required such as (form of educational, form of grade, method, teachers qualification, assistance from the government, mothers education) and research proved that there were differences with mothers age, working environment, educational background, infants experienced inclusion.

In our research to identify gene involved in the cuticle protein, we cloned a novel cuticle protein gene,ApCP15.5, from the Chinese oak silkmoth, Antheraea pernyi, larvae cDNA library. The gene encodes a 149 amino acid polypeptide with a predicted molecular mass of 15.5 kDa and a pI of 9.54. The ApCP15.5 contained a type-specific consensus sequence identifiable in other insect cuticle proteins and the deduced amino acid sequence of the ApCP15.5 cDNA is most homologous to Tenebrio molitor-C1B (43% protein sequence identity), followed by Locusta migratoria-76 (42% protein sequence identity). Northern blot and Western blot analyses revealed that the ApCP15.5 showed the epidermis-specific expression. The expression profile of ApCP15.5 indicated that the ApCP15.5 mRNA expression was detected in the early stages after larval ecdysis and larval-pupal metamorphosis, and its expression level was most significant on the first day of larval ecdysis and pupal stage. The ApCP15.5 was expressed as a 15.5 kDa polypeptide in baculovirusinfected insect cells.

고압호모지나이저 처리는 큰 전단력과 간단한 조작법으로 셀룰로오스 나노섬유의 제조에 있어 일반적으로 사용되는 방법이다. 본 연구에서는 TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical) 촉매로 산화된 표백 활엽수 펄프의 나노해섬도에 미치는 고압호모지나이저 처리 횟수의 영향을 조사하였다. 원자력간 현미경을 사용하여 단섬유의 치수를 측정하고 나노해섬도를 관찰하였으며 비표면적을 측정하여 해섬도를 평가하였다. 비표면적 측정용 샘플은 최대한 나노섬유의 응집을 억제하기 위하여 t-butyl alcohol로 용매치환 후 동결건조 방법으로 제조하였다.

Purpose: We evaluated whether the clinicopathological factors of papillary thyroid microcarcinoma (PTMC), especially tumoe size, are associated with subcinical central lymph node metastasis. Materials and Methods: A total of 160 patients diagnosed with PTMC who underwent total thyroidectomy with bilateral central lymph node dissection were enrolled in this study. All patients were clinically lymph node negative PTMC. Patients were divided into 2 groups according to the size of tumor (≤5 mm vs. >5 mm). Clinicopathologic risk factors for subclinical central lymph node metastasis were analyzed. Results: Subclinical central lymph node metastasis was detected in 61 (38.1%). Patients with tumors ≤5 mm had a lower frequency of extrathyroidal extension, multifocality and subclinical central lymph node metastasis. On multivariate analysis, only male and tumor size >5 mm were independent predictors of subclinical central lymph node metastasis; age, multifocality, bilaterality, extrathyroidal extension, lymphvascular invasion and lymphocytic thyroiditis were not. Conclusion: In this study, male and tumor size >5 mm were two independent predictive factors for subclinical central lymph node metastasis in PTMC. These are easier factors to assess before surgery than other factors when planning the central lymph node dissection. However, further long-term follow-up studies are needed to confirm the prognostic significance of subclinical central lymph node metastasis in PTMC.
