This paper presents the interrelationship between software quality character and engineering attributes. The software quality characteristics and subcharacteristics are excerpted from IS0/IEC 9126 standards, and the engineering attributes are from Deutsch and Willis〔4〕. Based on the previous studies a subjective judgement, trisected interrelationship(strong, medium, weak) bet these two groups are derived. The results are summarized in a table, and can be used as a quick reference guide to the software quality engineering application such as quality evaluations for software products, selection of key engineering attributes for high-quality software production, and so forth.

A study was carried out to establish a detection method for irradiated black and white pepper. Samples were packed in polyethylene bags and irradiated with 2.5, 5, 7.5, 10 and 15 kGy using a Co-60 irradiator. The samples were suspended in water, and alkalized with sodium hydroxide solution. Apparent viscosity was determined after heat gelatinization using a Brookfield DV-III rotation viscometer at 30 with 30, 60, 90, 120, 150, 180, and 210 rpm. Means and standard deviations of the viscosities of all samples decreased by increasing the stirring speeds. The viscosities increased in all samples by increasing the concentration. Regression expressions and coefficients of viscosity which decreased with increasing irradiation dose of 10% and 13% black pepper, and 7% and 10% white pepper were 0.9531 (y=-131.29x+1,769.0), 0.9725 (y=-351.33x+4,036.0), 0.9731 (y=2,208.0e^(-0.3546x)), and 0.9959 (y=5,116.0e^(0.2887x)), respectively, at 120 rpm. This trend was similar for all stirring speeds. These results suggest that the detection of irradiated black and white pepper at various doses is possible by the viscometric method.

Human-robot co-operation becomes increasingly frequent due to the widespread use of service robots. However, during such co-operation, robots have a high chance of colliding with humans, which may result in serious injury. Thus, many solutions were proposed to ensure collision safety, and among them, collision detection algorithms are regarded as one of the most practical solutions. They allow a robot to quickly detect a collision so that the robot can perform a proper reaction to minimize the impact. However, conventional collision detection algorithms required the precise model of a robot, which is difficult to obtain and is subjected to change. Also, expensive sensors, such as torque sensors, are often required. In this study, we propose a novel collision detection algorithm which only requires motor encoders. It detects collisions by monitoring the high-pass filtered version of the velocity error. The proposed algorithm can be easily implemented to any robots, and its performance was verified through various tests.

In modern society, people spend most of their time on various types of chairs. However, it is not easy for a designer to design a comfortable chair because satisfaction with the chair depends not only on the quantitative elements such as size, but also on the qualitative element such as the user’s feeling. To deal with these problems, there have been many studies on designing ergonomic chairs. This paper proposes the haptic-aided design (HAD) system to design an ergonomic chair. Based on the HAD system, the designer can experience whether the chair is comfortable or not through the haptic device, and also can modify the design parameters instantaneously. The haptic chair capable of controlling the design parameters in real time was proposed as a haptic simulator. The controllable parameters, such as seat height, reclining angle, stiffness of the backrest, and so on were selected based on the previous research related to ergonomic chairs. The proposed methodology will help reduce the development cost and time by replacing the process of making the real mock-ups and prototypes with the haptic chair.

A new graft cactus (Copiapoa scopa) cultivar ‘edstone’was developed at Cactus Research Institute, Gyeonggi-do A.R.E.S, in 2007. GCP563 and GCP618 were crossed in 2004 and we got 9 seedlings from this combination. After pedigree selection in 2005, one cultivar was finally selected through the test of specific character in 2007 and named as “edstone” “edstone”cultivar has red brown color and round globose shape with 15 ribs and its spines are black. This cultivar is able to produce 26.8 offshoots per plant. ‘edstone’cultivar has higher productivity and more slow growth than Copiapoa scopa cultivar.

A new graft cactus (Chamaecereus silvestrii f. variegata) cultivars “ellow Ttree”was developed at Cactus Research Institute, Gyeonggi-do A.R.E.S. in 2007. GC013001 and GC0110703 were crossed in 2005 and we got 42 seedlings from this combination. After pedigree selection in 2005, one cultivar were finally selected through the test of specific character in 2007 and named as “ellow Ttree” “ellow Ttree”has cylindrical shape of yellow color with 13～14 ribs. Formation of its offshoots is concentrated on the lower part of the plant. This cultivar is able to produce 13.9 offsets shoots per plant and its offshoots are hard.

A new rose variety, was selected from the progenies of a cross between “osai”and “okimeky”in 2006 after evaluation trials for three years (2004-2006). “altz”was developed because of many petals and powdery mildew resistance. A standard type with large sized flower, “altz”shows in 11.0 cm flower diameter. “altz”produces 130 stems･m-2 in a year. It has red-white color flower and 49.6 petals per flower. The stem length of cut flower was long with 69.3 cm. Vase life of the variety could be as long as 9.6 days.

The study aims to explore the situation of allotment garden and its implication from case study on the Kleingarten in German the Dacha in Russia and the Civic Garden in Japan. It has shown that the allotment gardens have gradually been an important for urban people to have recreation and health from agricultural activities. The results suggest that whereas most of kind of allotment gardens in three countries was perspectively enhanced according to their historic and social contexts, the basic rationales initiated were to provide recreation areas for supporting people health and preserving green areas in urban areas. To expand these kind of allotment gardens, we conclude that the establishment and amendment of the related law are needed to activate and enhance the allotment garden in Korea.
