Generally, spiral test has been used for evaluating course-keeping quality of a ship. But, there are many difficult problems in performing spiral test and reversed spiral test. Therefore, we propose zig-zag test instead of spiral test for evaluating curse-keeping quality of a ship. In this paper, K-T maneuvering response model is applied to the spiral curves which are systematically produced to calculate Zig-zag maneuver. Then, 1st overshoot angle and 2nd overshoot angle are plotted. And the relations between overshoot angles and band widths of spiral curve are discussed.

Strawberry and cucumber were dipped with Korean medical herb extracts such as Rheum palmatum L. and Coptis chinensis Franch. to maintain the keeping quality during storage at 5$^{\circ}$C and 10$^{\circ}$C, respectively. Treatment with 500 ppm solutions gor strawberry retarded weight loss, microbial load increase, and decay during storage. Decay ratio was shown 68.8% for control, 45.0% for Rheum palmatum L. and 42.5% for Coptis chinensis Franch. at 10 days. Strawberry treated with Coptis chinensis Franch. showed a higher hardness and soluble solid content than others. Cucumber treated with 1,000 ppm solutions revealed a different O$_2$ and CO$_2$ concentrations after 16 days. Korean medical herb extracts showed an antimicrobial activity for the quality retention of cucumber during storage. Ascorbic acid content was generally increased till 8 days, but decreased thereafter.

The complexity arises in defining the construction quality due to its perception, based on inherent market conditions and their requirements, the diversified stakeholders itself and their desired output. A quantitative survey based approach was adopted in this constructive study. A questionnaire based survey was conducted, for the assessment of construction quality perception and expectations in the context of quality improvement technique. The survey feedback of professionals, from the leading construction organizations/companies of Pakistan were analyzed. The financial capacity, organizational structure, and construction experience of the construction firms formed basis for their selection. After statistical analysis of survey feedback it was found reliable and valid for the inferential purpose to the target population of construction professionals. The quality perception was found to be project scope oriented, considered as an excess cost for a construction project and keeping the rework minimum by qualifying the required quality tests, keeping the defects minimum by ensuring the specifications of supplied material. Any quality improvement technique was expected to address the financial aspects of the construction project for the employer and contractor, by increasing the profitability through reduction in overall cost, reduction in time, reduction in defects and improving the productivity in a construction project. The study is beneficial for the construction professionals to assess the prevailing construction quality perception and the expectations from implementation of any quality improvement technique in construction projects.

The experiment was done to clarify the effect of keeping material and storage temperature on weight and quality of Chinese yam (Dioscorea opposita) tuber. After the yam tubers were placed into the plastic boxes filled with different keeping materials [polyethylene (PE) film, hull, soil, sand, vermiculite], they were stored under different storage temperature(room, cold) from Oct. 15 to Mar. 15 when all the characters related to the tubers were measured. Soil or PE film as keeping materials was the lowest sound tuber rate when stored at room or cold temperature, respectively, while vermiculite was the highest in both storage temperature. When PE film and vermiculite in both storage temperatures were used as keeping materials, tuber weight were less reduced than the others. Brightness of chromaticity and moisture content were lower in room temperature storage than in cold temperature storage although the characteristics related to marketability were not affected by storage temperature. PE film had greater brightness and value 'a' of chromaticity but lower its 'b' value in the latter temperature than in the former temperature. Vermiculite, however, did the reverse result in comparison with PE film.

The keeping quality of seasoned mackerel meat products during frozen storage were investi-gated for the effective utilization of mackerel as a food source. The pH and volatile basic nitrogen (VBN) contents of products revealed a tendency to increase slightly during frozen storage,. Viable cell counts(1.5$\times$104-2.0$\times$104/g) and histamine contents(2.45-2.89mg/100g) were decreased during frozen storage. In fatty acid composition of the products polye-nes such as 22:6, 18:3, 20:4 and 20:5 were the maincomponents. From the results of chemical experiments and sensory evaluation the products could preserved with good quality during frozen storage(-$25^{\circ}C$) of 120 days.

Effects on keeping quality according to the different package environment in cabbage and brccoli were studied. Opened 2 mil LDPE (low density polyethylene) sealed 4 mil LDPE and BA(barrier polyethylene) were used as package films. Weight loss was markedly in opened 2 mil LDPE in cabbage and broccoli as 6 and 28%, respectively. Carbon dioxide was higher in seal-packaging cabbage and broccoli with BA held at 4 $^{\circ}C$ was above 15 and 31% within 15 days, respectively, while oxygen content was depleted to 2% or less after 10 days. The main difference between volatile sulfur-containing compounds produced from cabbage and broccoli were the relative quantities and rates of production of hydrogen sulfide, carbonyl sulfide, methanethiol and dimethyl disulfide in opened 2 mil LDPE , sealed 4 mil LDPE and barrier bags during storage.

Tremendous computation of full search or lossless motion estimation algorithms for video coding has led development of many fast motion estimation algorithms. We still need proper control of computation and prediction quality. In the paper, we suggest an algorithm that reduces computation effectively and controls computational amount and prediction quality, while keeping prediction quality as almost the same as that of the full search. The proposed algorithm uses multiple thresholds for partial block sum and times of counting unchanged minimum position for each step. It also calculates the partial block matching error, removes impossible candidates early, implements fast motion estimation by comparing times of keeping the position of minimum error for each step, and controls prediction quality and computation easily by adjusting the thresholds. The proposed algorithm can be combined with conventional fast motion estimation algorithms as well as by itself, further reduce computation while keeping the prediction quality as almost same as the algorithms, and prove it in the experimental results.

Purpose: The purpose of the present study was to explore the meaning of quality of life in patients with chronic cardiovascular disease. Methods: A grounded theory method guided data collection and analysis. A total of 16 adult outpatients with chronic cardiovascular disease was participated. Data were collected through individual in-depth interviews. All interviews were audio taped and transcribed verbatim. Coding was used to establish different concepts and categories. A theoretical sampling technique was used to obtain diverse data from many relevant categories. Results: Seven categories were extracted, and they divided into constructing and intervening factors of quality of life. Constructing factors were uncertainty, recovery in the sense of control and maintaining social life. Intervening factors were symptom experiences, social support, taking care of themselves, and reflecting life. 'Keeping restrictive conditions under control' was emerged as a core category. The meaning of quality of life in patients with cardiovascular was explained according to the levels of keeping restrictive conditions under control. Conclusion: The result of this study may contribute for health professionals to understand the quality of life in patients with cardiovascular disease.

The antimicrobial extracts of rheum palmatum and coptis chinensis root as well as grapefruit seed extract(GFSE) were applied to dipping treatment for keeping qualities of cucumbers, respectively, which were then packed in low density polyethylene(LDPE) films incorporated with 1 % antimicrobial extracts and stored $10^{\circ}C$. Dipping and packaging in the antimicrobial agents suppressed the growth of putrefactive microorgani는 and the decay ratio of cucumbers. In addition, the loss ratio of ascortic acid content and their weight was decreased during the sotrage of cucumbers. Consequently, the combined method of dippinf and packaging in antimicrobial agents turned out to be superior to dipping treatment or film-packaging in the view point of decay ratio and the keeping qualities of cucumbers.
