      • Recurrent thymic carcinoid tumor in familial isolated primary hyperparathyroidism

        송정,무현,김가영,이다영,이정훈,김종호,호상,이지현,전언주,정의달 영남대학교 의과대학 2014 Yeungnam University Journal of Medicine Vol.31 No.2

        Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.

        수종의 BRACKET(DBS)제거방법에 따른 법랑질 표면에 대한 주사전자현미경적 연구

        송정,병화 대한치과교정학회 1985 대한치과교정학회지 Vol.15 No.2

        With modification of the acid etch technique and improvements of the physical and mechanical properties of the acrylic resin, the removal of directly bonded attachments and the finishing of the underlying enamel have become an acute clinical problem. This study was to evaluation the efficacy of recently introduced instrumentation and techniques to remove bonded brackets and residual resin, and restore the affected enamel surface to an acceptable clinical condition. Forty-eight premolar which were scheduled for extraction for orthodontic purposes were bonded with brackets using super-C ortho Four additional premolars with untreated surfaces were used as controls . After one weak the brackets were removed and the residual resin removed by hand scaler, green stone, green rubber wheel, sandpaper disc, tungsten carbide bur, Sof-lex disc. Half the experimental teeth were given a final pumicing and then all were extracted and stored in 50 percent ethanol. The scanning electron microscopy was used to evaluated the enamel surface. Following results were obtained; 1. A satisfactory result was obtained by means of the Sof-lex disc. 2. The order of the scratch formation was the procedure using hand scaler, green stone, tungsten carbide bur, sandpaper disc, green rubber wheel, and Sof-lex disc. 3. The procedures using green stone and tungsten carbide bur showed many groove formations and the other procedures showed none. 4. Final pumicing serves effectively to remove residual abhesive and restore the enamel surface.

For the purpose of mass s production of the seedling of top shell, Batillus cornutus (LIGHT FOOT) in Cheju Do, 387 samples were collected at the southern coast of Cheju Island. Their shell height were ranged 51.9-93.1mm and the experiment to stimulate the spawning induction were excuted 7 times during the period of July, 1985 and August, 1985. The results of egg development, planktonic larvae seed collection, growth and survival rate in relation to the rearing process of settling larvae were as follows: 1. The method of induced spawning stimulation which practiced drying by means of non-circulation on the night before stimulation while irradiating the seawater with ultra-violet ray was most effective. 2. The range of response rate, and fertilization rate of samples by the above method was 10.42%∼36.84% and 71.45%∼93.02% respectively. 3. The range of fertilization rate against spawning was 63.25%∼80.12%. 4. The average of settling numbers per swimming larvae collector in relation to collector set-up method were 367.38±67.58 individual (0.31 individual/㎠) and 428.25±318.50 individual (0.36 individual/㎠) in vertical and horizontal settling respectively. 5. Vertical distribution of attached young top shell on the wall surface in aquarium was 90.14% of total young top shell and this was appeared between the water surface and 30cm depth which was abundant in settling of attatched diatom up 70 days after hatching. 6. The growth relationship equations between shell diameter and growth of 70 days after hatching of young top shell in autumn collection were the linear regression line of S=0.0090D+0.4236 and S=0.0109D+0.4253 in case of small circular aquarium (ψ1.6×0.7m) and rectangular one (2.5×1×0.7m) respectively. 7. Mass motality of young top shell after attatching was detected within 20 days after hatching. Survival rates were 49.28% and 40.36% in circular aquarium and rectangular one respectively. During this period while percentages of survival after 70 days were 9.11%, 8.93% in former and latter respectively.

        통합 산림자원 관리와 디지털 산림정보 구축 지원을 위한 유역 기반 표준산림관리단위의 설정과 활용

        노영희,민수희,홍성희,송정,학기,김종민 한국지도학회 2023 한국지도학회지 Vol.23 No.2

        For efficient forest management, forest zoning methods must be defined with a certain spatial unit. Currently, national forests are divided into compartment and sub-compartment, and public and private forests are divided into parcel units. This dual spatial division system is not efficient in terms of unified forest planning and management. It can also lead to difficulties in creating and managing spatial forest information in the long-term perspective. In this study, we introduced forest zoning system based on mountain ridge watersheds and conducted an overlapping analysis with the current forest zoning system such as compartment and sub-compartment, working plan area, and forest thematic maps for utilization. As a result, we examined the spatial suitability of each scale of forest watershed unit proposed as a standard forest management unit and proposed the utilization of mountain ridge watershed-based standard forest management units for forest management and forest digital spatial data construction.

        소양호산 쏘가리 Siniperca scherzeri(Pisces , Centropomidae)의 산란 생태와 초기 생활사

        이종윤,이완옥,최낙중,송정 한국어류학회 1997 韓國魚類學會誌 Vol.9 No.1

        쏘가리의 양식과 자원 증강을 위한 기초 자료를 얻기 위하여 1996년 6월부터 10월까지 강원도 춘천시 북면의 소양호내에서 산란 생태와 초기 생활사를 조사하였다. 성체의 동소종으로 6과 10속 11종이, 자치어의 동소종으로 3과 4속 4종이 채집되었다. 암수 성비는 1 : 1.24이었다. 본 종의 식성은 성체와 치어 모두 육식성 중에서도 어식성이었고, 파랑볼우럭, 피라미, 잉어 와 미동정 어류, 새우를 섭식하였다. 수정란은 구형의 침성 분리란이었으며, 난막은 투명하였다. 난황은 연한 황색이었으며, 대형 유구(0.5∼0.7㎜)가 1개 있었다. 수정란은 1.72∼2.05㎜(n=30)이었으며, 수정후 30분이 지나면 난막이 팽창하여 2.27∼2.58㎜가 되었다. 수온 20∼25℃에서 수정후 130∼155시간에 부화되었고, 부화 직후의 자어의 크기는 5.5∼7.1㎜였다. 갓 부화된 자어는 난황 표면과 미병부의 복부에 흑색소포가 발달되어 있었다. 부화 10일 후에는 난황의 흡수가 완료되고, 두부와 이빨이 발달되었다. 20일 후에는 모든 지느러미가 성체와 같았고, 전장도 13.6∼15.6㎜로 성장하였다. 부화 55일 후에는 성체와 체형과 체색이 유사하였다. 부화 후 4개월이 지나면 전장 86.4∼95.3㎜ (n=7), 체중 8.77∼14.78g (n=7)의 치어기에 도달하였다. The early life history and reproductive ecology of Siniperca scherzeri were studied to obtain fundamental information in aquaculture and reinforcement of natural population in Soyang Lake, Buk - myon, Chunchon - shi, Kangwon - do from June to October 1996. Symptric species with adult fishes (+1 ages) of Siniperca scherzeri were 11 species belonging to 6 families and 10 genera and those with Juveniles (2∼3 months) were 5 species belonging to 4 families and 5 genera. The sex radio of this species were 1 (female, 85) : 1.24 (male, 105). Adult and juvenile of this species were predominantly piscivores. Bluegill, Lepomis macrochirus, Zacco platypus, co㎜on carp, Cyprinus carpio, unidentified fish and shrimp were important components of the food items. The spherical eggs were demersal and separative without a colorless transparent chorion and slightly yellowish yolk containing one large oil globule (0.5∼0.7㎜). The egg just after fertilization were measuring 1.72∼2.05㎜ (n=30), and expanded to 2.27∼2.58㎜ (n=30) in diameter after 30 min. Hatching occurred 130∼155 hrs after fertilization at water temperature of 20∼25℃ and newly hatched larvae measuring 5.5∼7.1㎜ in total length. In the newly hatched larvae, numerous branched malanophores were distributed on the yolk and abdomen of caudal peduncle. In ten - day old larvae, the yolk was mostly absorbed and the head spines and the teeth were well developed. All fin rays were formed and total length of the larvae were reached 13.6∼15.6㎜ at 20 days after hatching. In fifty - five day old larvae were similar in both body shape and color to adult. The juvenile stage at 4 months after hatching were attained 86.4∼95.3㎜ (n=7) in total length and 8.77∼14.78g (n=7) in body weight.
