The Internet of Things, the core of the Fourth Industrial Revolution, is growing by applying various technologies to various fields. Among them, smart home systems that apply IoT technology to home environments are actively being researched, and the home hub market, which is a communication medium for smart homes, is also developing at the same time. However, the security damage from cyber attacks, which are vulnerabilities in IoT technology, is also increasing in proportion to these developments. In this paper, mirror is implemented as an IoT service hub. It can be used in any space where a mirror is installed, and gesture recognition allows control of existing infrared-based devices as well as certain compatible devices. In addition, the system to solve security problems was implemented by applying AES algorithms between all data communications.

The egg development and morphological development of larvae and juveniles of crucian carp, Carassius auratus (Linnaeus) caught at Bosung River, Chollanam-do, in April to June, 1999 were investigated in the laboratory, Yosu National University. In the spawning season, the nuptial organ was appeared on the opercular region and under region of eye, pectoral fin, ventral fin and lateral line. The egg was transparent of yellowish brown color, demersal of adhesive and sperical in shape, measuring 1.49∼1.63㎜ (mean 1.57㎜, n=50) in diameter. The first hatching was occured in 75 hours 10 minutes after fertilization in water temperature 18.3∼21.7℃. Newly hatched larvae attained mean 4.28㎜ had a big yolk sac and their mouth, and anus were not opened yet. At 5 days after hatching, the larvae attained mean 5.34㎜ and the yolk sac was almost absorded. At 13 days after hatching, the larvae attained mean 7.21㎜. The caudal notocord was flexed 45°upward, and they reached post larvae stage. At 31 days after hatching, the larvae, mean 14.68㎜ in TL reached the juvenile stage with all of the fins formed with complete set of the fin rays (D. ⅩII-11∼15; A. Ⅲ-5∼6; P. 15∼16; V. 1-8).

In order to evaluate the indoor air quality of the building offices and to know the health symtoms of office workers, this questionaire survey was conducted from the 570 workers employed in the 9 large buildings(4 naturally ventilated and 5 mechanically ventilated) in Taejon area from 1 July, 1993 to August, 1993. The results were summarized as follows. 1. An opinions of the building office workers on the indoor air quality was higher in the rates of dissatisfaction as 57.0% than that of satisfaction as 43.0%. 2. The dissatisfaction rates by the workers on the indoor air quality were higher in the mechanically ventilated buildings than naturally ventilated, buildings compared with contributing factors such as age, sex, marital status, duration of work, work hours per day, number of workers per floor space, smoking in the office, operate a computer and a copier in the office etc. 3. The reasons of dissatisfaction by the office workers on the indoor air quality were "bad circulation", "dusty", "too dry", "too hot" and "noisy" in that order. But the "ban circulation " " dusty" and "too dry" were significantly higher in the mechanically ventilated buildings than the naturally ventilated building( P<0.05). 4. Most workers answered the times when the indoor air quality is worst were during "hot", in the "afternoons", "crowdy" and "cold" in that order. Especially, the times when "Rainy and snowy" and "crowdy" were significantly higher in the mechanical ventilated buildings than the naturally ventilated buildings(P<0.05). 5. They complained symptoms such as "congested eyes" "runny nose" "stuffy nose" "nausea" and "drowsiness" and the rates of symptoms complained were significantly higher in the mechanical ventilated buildings than the naturally ventilated buildings (P<0.05).

한경호,황동식 한국어류학회 2003 韓國魚類學會誌 Vol.15 No.1

본 연구는 2001년 5월부터 10월에 광양만, 가막만 및 여수시 돌산도 연안에서 채집한 Scartella cristata의 발육단계에 따른 자치어의 형태를 관찰하였다. 채집돈 Scartella cristata 자치어는 총 235개체로 주로 7월과 8월에 각각 78개체, 93개체가 채집되어 가장 많았고, 체장범위는 2.53~15.85㎜였다. 본 종의 자치어들은 몸의 형태, 체형, 계수형질 및 흑색소포의 분포 상태가 Okiyama(1998)가 보고한 Scartella cristat의 결과와 일치하였다. Scartella cristata는 한국 미기록 어종으로 머리부분에 여러갈래의 피질돌기가 갈기 모양으로 형성되어 있는 특징에 근거하여 “갈기베도라치”로 국명을 신칭하였다. 평균 체장 2.57㎜의 자어는 난황이 완전하게 흡수되어 있고, 근절은 28~30개였다. 평균 체장 5.95㎜ 이상의 개체에서 완전하게 위로 굽어져 있었다. 평균 체장 10.50㎜ 전후의 개체들은 모든 지느러미 줄기가 정수에 달하여 치어기가 이행하였고, 평균체장 12.20㎜ 치어들은 코 부분과 눈 윗부분에 갈기모양의 피질돌기가 형성되기 시작하였다. The development of larvae and juveniles of the blenniid fish, Scartella cristata were studied based on the specimens collected in coastal waters of Yosu, Korea from May to October, 2001. 235 individuals of the species were collected during the study, which were 2.53-15.85㎜ in standard length. Body form, meristic characters and distribution of melanophores coincided with those of Scartella cristata described by Okiyama (1988), which was not revealed from Korean. Therefore, we proposed it's new Korean name as "Gal-gi-be-do-ra-chi". Yolk was completely absorbed when the larvae was about 2.57 mm in average standard length (ASL), with 28-30 myomeres. Flexion of the notochord started when the postlarvae was about 5.12 ㎜ in ASL and finished about 5.95 mm in ASL, respectively. The larvae had reached at the juvenile stage when 10.50㎜ in ASL and all the fins were completed. The cirri and fleshy crests were begun to appear on the snout and upper region of eye respectively when 12.20㎜ in ASL.

We study the characteristics of a chaotic oscillator with the change in slope of a nonlinear negative resistor by phase portraits, Poincare mappings and time waveform measurements. An internal resistance Rp was used as a control parameter which is closely related with the coefficient of the first order term. We observed a bifurcation and chaotic phenomena with various Rp ranging from 1.388kΩ to 1.658kΩ. This result can be applied to the technology of a security communication and an encoded signal synchronization in the near future.
