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 this paper, we design a GA-fuzzy controller for position control and anti-swing at the destination point. Applied genetic algorithm is used to complement the demerit such as the difficulty of the component selection of fuzzy controller, namely, scaling factor, membership function and control rules. Lagrange equation is used to represent the motion equation of trolley and load in order to obtain mathematical modelling. Simulation results show that the proposed control technique is superior to a conventional optimal control in destination point moving and modification.

The use of a layering technique in stiffness matrix for specially orthotropic laminated plates is introduced. Stack of simple four-node plane stress and Mindlin plate elements is used to compute laminated elements subject to membrane and bending loads. Laminated plates among the various structural forms using composite materials have been generally used but,it is difficult to apply classical theory to these anisotropic materials because of existing stretching-shearing,bending-shearing,stretching-twisting coupling,e.t.c. Therefore, the investigation of stiffness matrix about laminated plates with various stacking sequences and fiber orientations is conducted in this paper.

Moyamoya disease is an occlusive intracranial arteriopathy with an abnormal cerebral vascular collateral networks. Although this disease is known to be associated with stenosis of extracranial arteries, such as the renal artery, a case associated with stenosis of the coronary artery is extremely rare. We report a case of coronary artery occlusive disease affected by Moyamoya disease. The patient was a 38-year-old female experiencing intermittent headache and exer tional chest pain. Cerebral MRI showed complete obstruction of both internal carotid arteries and abnormal cerebrovascular systems which confirmed Moyamoya disease. Coronary angiography showed a significant stenosis of left anterior descending coronary artery ostium with TIMI grade I collateral blood flow from the normal right coronary artery. After coronary artery stenting and medical treatment for headache, her subjective symptoms were relieved. In Moyamoya patient, an evaluation of the extracranial (especially coronary artery) vascular system should be considered if there are some evidences of coronary artery disease.
