  • In this study, We made visual inspection system using Vision Board. It is consist of an illuminator (a fluorescent lamp), image input device (CCD (Charge-Coupled Device) camera), image processing system(Vision Board(FARAMVB-02)), image output device (video monitor, printer), and a measuring instrument(TELMN1000). Length measurement by visual inspection system make use of 100mm guage block(instead of calculating distance between a camera and a object). It measured horizontal and vertical length factor from 400mm to 650mm by increasing 50mm. In this place, measured horizontal and vertical length factor made use of length measure- ment of a injection. A measuring instrument used to ompare a measured length of a injection visual inspection system with it. In conclusion, length measurement of a injection compared a measuring instrument with visual inspecion system using length factor of 100mm gauge block. We find that maximum error of length is 0.55mm when it compar with the measuring value of two devices(FARAMVB-02, TELMN1000). Program of visual inspection system is made up Borland C++3.1.

  • 일제 강점기 여성들 one length hair style의 변천사 및 형태학적 분석을 시도한 연구로서 선행논문과 저서를 바탕으로 형태, 질감, 색상 등 헤어디자인의 구성 요소들을 분석하여 다양한 형태의 one length hair style 커트가 가능해지는데 연구의 목적이 있다. 연구 결과 1910년-1920년대 one length hair style은 커트 길이의 단차가 전혀 없는 out line을 지닌 형태, 자연 그대로의 모발 질감, 자연 모발 색상을 보였다. 1930년대 one length hair style은 약간의 커트 길이의 단차를 보이면서 다이아몬드 형태, 자연스런 질감의 narrow wave, 과산화수소나 oxygenated water을 이용한 약간의 탈색이 이뤄졌다. 1940년대 one length hair style은 형태, 질감, 색상 면에서 화려한 미(美)를 추구하려는 특이점이 발견되지 않았다. 본 연구를 통해 one length hair style에 관한 심층적이고 세분화 된 후속 연구가 가능해지며, 헤어미용 교육의 기초 자료 및 뉴 모드의 트렌드 개발을 위한 초석으로 작용하리라 사료한다.

  • The fertilized eggs of E. septemfasciatus are spherical and transparent with buoyancy at 790 to $890{\mu}m$ (average $821.8{\pm}2.0{\mu}m$) in diameter with 170 to $230{\mu}m$ oil globules (average $192.9{\pm}0.93{\mu}m$). Hatching began approximately 46 and 35 hours after fertilization at $22.0^{\circ}C$ and $25.0^{\circ}C$ water temperature, respectively. The average total length of newly hatched larvae was $1.75{\pm}0.03mm$. Most of the yolk and oil globules were absorbed within 3 to 4 days after hatching. The larvae reached 2.48 to 2.72 mm in total length, and their mouths and anuses opened at 3 to 4 days after hatching. In this time, the mouth diameters of the larvae were 0.209 to 0.238 mm. The larvae reached 3.24 to 4.15 mm in total length at 11 to 17 days after hatching, and began to metamorphose at the time the second dorsal and pelvic spines appeared and elongated. The abdominal cavity was densely lined with melanophores. The larvae reached 5.12 mm in total length at 24 days after hatching.

  • This study was conducted to observe egg and larvae morphological development of carp to obtain basic data for resource conservation and taxonomic research. Brood carp used in the research (total length 67.3-75.5 cm, average $71.0{\pm}3.45cm$) were bred in a circular rearing aquarium ($600{\times}300{\times}100cm$) using a running water system from January to July, 2015. Breeding water temperature was maintained at $23.0-25.0^{\circ}C$(average $24.0^{\circ}C$). Fertilized carp eggs were translucent and globular, and their size was 1.75-1.89 mm (average $1.82{\pm}0.06mm$). Blastoderms formed 10 min after fertilization and reached the two-cell stage 30 min after fertilization. Then, the embryo turned dark and exhibited melanophores, and blood started flowing from the heart across the egg yolk at 42 hrs and 50 min after fertilization. Hatching began 70 hrs and 26 min after fertilization larvae emerged through the egg membrane, starting from the head. The length of prelarvae immediately after hatching was 5.23-5.38 mm (average $5.31{\pm}0.11mm$) the mouth and anus were closed, and the pectoral fin was formed. Postlarvae at 18 days after hatching had a total length of 11.9-13.9 mm (average $12.9{\pm}1.40mm$), separate anal fin and back membranes, and fin ray. Juveniles fish at 35 days after hatching had a total length of 29.9-30.2 mm (average $30.1{\pm}0.13mm$), with the body covered with scales, and the same number of fin rays, color, and shape as their broodstork.

  • 대서양 남빙양 새우의 주된 분포역은 South George Island, Laurie/Coronation Islands와 Livingston/King George Islands 지역으로 공간적인 구분을 뚜렷이 하였다. 어획 수심은 층에서 150 m층까지 달했고, 10 m층으로 구분한 단위노력당어획량의 수직 분포는 층간에 큰 차이가 없었으나 수심이 깊어 질수록 낮아지는 경향을 보였다. 수온과 단위노력당 어획량의 관계로 부터 남빙양 새우는 주로 $0.8{\sim}l.0^{\circ}C$ 범위에서 높은 밀도를 나타내었다. 남빙양 새우의 암수별 체장 조성은 큰 차이를 보여 숫컷의 비율은 작은 체장에서, 암컷의 비율은 큰 체장에서 각각 높았다. 두흉갑장과 체장관계, 체장과 체중관계가 암수별로 추정되었다. 암수별 성비조성은 숫컷이 $60.3\%$, 암컷이 $39.7\%$로서 유의한 차이를 나타내었다.

  • The aim of this study was to investigate changes in 7 nutritional components (fatty acid, protein, fat, ash, total dietary fiber (TDF), $\gamma$-aminobutyric acid (GABA), and $\gamma$-oryzanol) of paddy rice (PR) and brown rice (BR) throughout the germination process, as measured at different shoot lengths (10 mm, 20 mm, and 30 mm). With the increase of shoot length, the nutritional components' concentrations increased, as compared to the concentrations measured before germination. Moreover, BR exhibited higher GABA, $\gamma$-oryzanol, and protein than PR. Among the components, TDF, GABA, and $\gamma$-oryzanol showed significant concentration differences throughout germination, while the others exhibited only slight variations. In particular, GABA and $\gamma$-oryzanol were predominantly increased in grains of 10 mm shoot length. These compounds might prove to be important factors from germinated rice. Additionally, the germinated cultivar 'Keunnun' might also prove to be a very important food source, owing to its high GABA and $\gamma$-oryzanol contents. These results suggest that variations in nutritional components related to the increase of shoot length may prove to be important when considering the beneficial aspects of rice on human health.

  • The morphological and histological changes of gonad in ridgetail prawn (Expalaemon carinicauda) were examined with the development of the external genitalia. The samples were collected monthly in Hampyung Bay on the western coast of Korea, from January to December 2003. The ovaries lie on the dorsal side of the female prawns thorax. The ovary cavity is located below the heart and above the hepatopancreas. The anterior part of the ovary is round and fused, and the posterior part has a pair of tubular structures. Testes are bilaterally symmetrical; the anterior part shows fused feature, and the posterior part consists of a pair of tubules. Based on histological examination, ripe eggs and spermatozoa were observed when mature females and males reach a length of about 14.9 and 11.5 mm CL, respectively. The immature female are almost same shape and structure with matured one in the endopod of first pleopod and appendix interna of the second pleopod, except the number of setae, and appear to be structurally complete after females reach a length of about 14.9 mm CL. The appendix masculina reaching beyond the distal end of the appendix interna of the second pleopod after males reach a length of more than 5.5 mm CL and a fully developed appendix masculina and appendix interna of the second pleopod appear up to a length of 11.5 mm CL.
