These days the automobile industry, which has rapidly progressed, has been an indispensable part in social and economic activities as well as its research and development have been activated in response to various needs of consumers and markets. The second and third generation control system, getting count on safety and convenience differently than early circuits, cause the hypertrophy of wire harness. The J/Box(Junction Box), which distributes power and wires, was developed to solve the problem. As vehicles have been better in quantity and intelligence, however, environment-friendly electric apparatus system has continuously increased and ITS(Intelligent Transport System) has been introduced in earnest. In result, wires got complicated and multilateral and also there has been a stronger probability that vehicles are out of order due to various problems including mechanical failure. In this study, ISJB(Intelligent Smart Junction Box) was introduced to solve the problem. The diagnosis system was applied to prevent the overload and short of ISJE. Also, the state of vehicles displayed so that drivers monitor it in motion. Likewise error data are saved in the memory so that such data can be analyzed retrospectively. The busbar was adopted in to the main power terminal and the part of power pattern was coverd by lead. Because ISJB is more sensitive to heat in comparison to the busbar type J/Box. With regard the circuits related with safe, alternative circuits were set up in order that electronic devices may be normally operated even when an error arises. ISJB is expected to improve the safety and quality of vehicles.

The present study was conducted to evaluate nutritional intake by lunch-box of middle school girls who live in Chonbuk area. Anthropometric measurements and food intake from lunch-box over a three day period were investigated in a total of 110 middle school girls from rural (n＝37) and urban (n＝73) areas. The results are summarized as follows : 1. Not all the steamed rice in the lunch-box had enough mixed-cereal. 2. In the survey of food intake by food groups, 70.5% of the food came from the cereal group. 3. The intake of protein, phosphate, Vitamins $B_1 and B_2$, niacine and Vitamin E were adequate, however, the intake of other nutrients was significantly lower than those of one-third of the Korean RDA.4. Protein, lipid, and zinc intakes of the students from the rural area were significantly lower than those of students from the urban area. however, the carbohydrate and dietary fiber intakes of those in the rural area were significantly higher than those of the students in the urban area. 5. The percentage of calories from carbohydrate : protein lipid ratio was 67.6 : 12.2 : 16.9 for students in the rural area and 59.2 : 14.9 : 22.5 respectively for those in the urban area. In Summary, the intake of calcium, iron, Vitamins A, $B_6$, and D, folate and zinc from lunch-box in middle school girls was much lower than that of one-third of the Korean RDA. The intake of carbohydrate and dietary fiber of the students in the rural area was significantly higher, but that of protein, lipids, and zinc was lower than that of the students in the urban area. Therefore, nutritional education programs for both students and their parents should be provided to improve the daily food intake from lunch-box.

The aims of this study were to investigate usage status, menu preference, quality evaluation and satisfaction of home-delivered meal box for children from low-income families in Chungcheongbuk-do, Korea. A total of 320 children and their guardians who had received home-delivered meal boxes participated in 2015. A total of respondents (62.2%) were children and teenagers, and 37.8% were guardians. The 47.7% of children and 43.8% of guardians were using the home delivery service more than one year. Most of the children and guardians answered 'eat almost', 'eat all meals' served meal box, 75.3%, 81.8%, respectively. After receiving the meal box at home, 35.2% of children consumed meals within 1~2 hours, whereas 32.8% of the guardians were ate within 2~6 hours. It was founded that 'throw away leftovers' was the highest and followed 'give it others' in a way to treat leftovers. The results of preference survey on meats, seafood, showed that 'chicken nugget' (4.07) and 'stir-fried fish cake with vegetable' (3.63) were the highest points for children, whereas 'grilled LA beef ribs' (3.98) and 'stir-fried anchovies' (3.72) were the highest point for guardians. 'Seasoned leaves marinated in soy sauce' was the highest preference among vegetables and another dish for respondents. Frozen products were the most preferred types of meal boxes on the menu. In the quality evaluation of home-delivered meal box, although satisfaction with service and packaging of the meal box were high, the satisfaction of food quality was relatively low.

During mitosis. the proper segregation of duplicated chromosomes is corrdinated by a spindle check-point. The bifurcated spindle checkpoint blocks cell cycle progression at metaphase by monitoring unattached kinetochores and inhibits mitotic exit in response to the misorientation of the mitotic spin- dle Ibd1p/Bfa1p is a spindle checkpoint regulator of budding yeast in the Bub2p checkpoint pathway for mitotic exit and its disruption abolishes mitotic arrest when proper organization of the mitotic spin-dls inhibited. Ibd1p/Bfa1p localizes to the spindle pole body, a microtublue-organizing center in yeast, and its overexpression arrests the cell cycle in 80% of cells with an enlarged budy at mitosis and in 20 % of cells with multiple buds. In this study, we found that the C-terminus of Ibd1p/Bfa1p phys-ically interacts with Skp1p, a key component of SCF (Skp1/cullin/F-box) complex for ubiquition-medi-ated proteolysis of cel cycle regulatores as well as an evolutionally conserved kinetochore protein for cell cycle progression. A putative F-box motif was found in the C-terminus of Ibd1p/Bfa1p and its function was investigated by making mutants of conserved residues in the motif. These Ibd1p/Bfa1p mutants of a putative F-box interacted with SKp1p in vitro by two-hybrid assays as wild type Ibd1p/Bfa1p. Also these Ibd1p/Bfa1p utants displayed the overexpression phenotypes of wild type Ibd1p, when over-expressed under inducible promoters . These results suggest that a putative F-box motif of Ibd1p/Bfa1p is not essential for the interaction with SKp1p and its function in mitotic exit and cytokinesis.

In this study, the effects of psychosocial stress (box color and precision demand) on muscle activity were evaluated in laboratory setting. Eight subjects performed sagittally symmetric lifting tasks. Box color (yellow, black), precision demand (yes, no), and box weight (5%MVC, 10%MVC, 15 %MVC) were varied and surface EMG signals from seven muscles(medial deltoid right, biceps brachii right, lateral triceps right, latissimus dorsi right, erector spinae right, external oblique right, internal oblique right) were recorded. EMG signals were band-pass filtered($10{\sim}400\;Hz$), rectified, RMS smoothed and normalized (NEMG). Analysis of variance tests were conducted on the total NEMG (TNEMG: the sum of the seven muscles' NEMGs) and on the individual muscle's NEMGs. Box color had no effect on the TNEMG and on the seven muscles activities(p>0.05). When precision demand was required at the end point of lifts, the mean NEMG showed higher values than no precision demand conditions: TNEMG (14% increase) and medial deltoid(40% increase), biceps brachii(10% increase), lateral triceps(26% increase), latissimus dorsi(25% increase) muscles. Those increases showed more conspicuous as the box weight increased in the muscles of medial deltoid, lateral triceps, and latissimus dorsi.

In this study the seismic performance of welded steel moment connections to built-up box columns in the existing building built before 1994 Northridge earthquake was evaluated by cyclic tests. According to the test results, the pre-Northridge steel moment connections to the box columns also suffered from brittle fracture similar to that in the H-shaped column connections. However, the flange force transfer mechanism of the box column connections was substantially different from that of the H-shaped column connections, and the patterns of crack propagation may be changed due to the shape of the box column. Therefore, it is required to develop proper details for the box column connections instead of using the research results for H-shaped column connections in order to enhance the seismic performance the connections.

As differential computation analysis attack(DCA) which is context of side-channel analysis on white-box cryptography is proposed, masking white-box cryptography based on table encoding has been proposed by Lee et al. to counter DCA. Existing higher-order DCA for the masked white box cryptography did not consider the masking implementation structure based on table encoding, so it is impossible to apply this attack on the countermeasure suggested by Lee et al. In this paper, we propose a new higher-order DCA method that can be applied to the implementation of masking based on table encoding, and prove its effectiveness by finding secret key information of masking white-box cryptography suggested by Lee et al. in practice.

In the combat environments at the sea, the naval ships should have enough structural integrity to perform the task under the enemy's attack and possible damages. Although the naval ships can be damaged from the enemy's attack, those damages should be minimized and the naval ships must maintain their combat capabilities continuously after recoveries from the damages. Therefore, it is ve교 important for modem naval ships, especially combat naval ships, to ensure the survivability. This paper reviewed the developing procedure for the technique of the naval ships structures and described method, especially box girder system considering survivability. The efficiency of box girder is examined by numerical simulation, and it is found that the establishment of box girder is a good design method to improve the survivability.
