Objective : The purpose of this study is to explore the effectiveness of a perceptual motor program in promoting visual motor and motor control outcomes in a child with Attention-Deficit/Hyperactivity Disorder (ADHD) who is enrolled in an elementary school. Methods : The subject is 8-year-old boy who was diagnosed with ADHD but did not receive medication. Research design is a single-subject A-B-A(follow-up). Baseline and follow-up phase were 3 sessions and intervention phase were 8 sessions. After performing 40 minutes of free play on the baseline A and follow-up A, we used the copying subtest of the Korean Development Test of Visual Perception 2 (K-DTVP-2) for evaluating visual motor integration skill and the rope jumping subtest for motor skill. After providing the perceptual motor activity in intervention phase B, copying and ropejumping were performed. Results : The standard scores of the Copying for measuring visual motor integration skill were poor at an average of 4.7 points at baseline phase A, but maintained an average of 9.6 points at intervention phase B and an below average of 7.7 points at the follow-up phase A. In the Rope jumping for the motor skill, it was increased by 4.3 times in the baseline phase A and 5.9 times in the intervention phase B, but slightly decreased by 5 times in the follow-up phase A. Conclusion : This study suggests that perceptual motor program has a positive effect on visual motor and motor function of ADHD children.

Integration applications, such as EAI, B2Bi, need stable massive data processing systems during overload state cause by service request congestion in a short period time. In this paper, we propose the PLC (Peak Load Control)-based Worker-Linker pattern, which can effectively and stably process massive I/O transactions in spite of overload state generated by service request congestion. This pattern uses the delay time algorithm for the PLC mechanism. In this paper, we also show the example of applying the pattern to business-business integration framework and the experimental result for proving the stability of performance. According to our experiment result, the proposed delay time algorithm can stably control the heavy overload after the saturation point and has an effect on the controlling peak load.

We firstly tried to understand consumers' purchasing tendencies and mainly focused on designing a platform model that offers integrated support. C2B (Customer to Business) orders integrate with a consumption platform of a B2C (Business to Customer) model, and integrated support aims at design, supply, processing, and distribution of a fashion business. All the information such as orders, sales, production, supply, and settlement of accounts is synchronized under the C2B, B2C, and O2O (Online to Offline) environment so that accurate information can be shared in real time. Our platform automatically handles with a net income of a product designer, manufacturer, and shipping company once shipping is confirmed.

Product catalog information is the most important factor to make customers purchase the product for various B2B or B2C businesses provided on the Internet. As catalog information differs from company by company, it cannot provide common criteria standard to customers to make decisions. Therefore, it is necessary to develop a platform independent system, which integrates incompatible data from each company' catalogs and manages its database. This paper describes the integrated E-catalog system made up DB module, catalog management module, and interface module. This system allows customers to view standardized product catalog information from different companies with real -time updates, and also provides extensibility, flexibility, and interoperability for the effective E-Business management.

The alkaline elastase is an extracellular serine protease of the alkalophilic Bacillus strain Ya-B. To increase the gene copy number and the production level of the alkaline elastase Ya-B, we designed, on the B. subtilis chromosome, a gene amplification of the 10.6 kb repeating unit containing amyE, aleE (alkaline elastase Ya-B gene) and tmrB. The aleE was inserted between amyE and tmrB, and B. subtilis APT119 strain was transformed with this amyE-aleE-tmrB-junction region fragment. As a result, we succeeded in obtaining tunicamycin-resistant (Tm$^{r}$) transformants (Tf-1, Tf-2) in which the designed gene amplification of 10.6 kb occurred in chromosome. The transformants showed high productivity of $\alpha $-amylase and alkaline elastase Ya-B. The copy number of the repeating unit (amyE-aleE-tmrB) was estimated to be 25, but plasmid vector (pUC19) was not integrated. The amplified aleE of chromosome was more stable than that of plasmid in absence of antibiotics.

A cooperative Korea-Japan investigation for the demersal fisheries resources of the East China Sea was carried out by using the training ship Oshoro Maru belong to Hokkaido University Japan, during 5-12 November, 1989. The research vessel sampled 24 stations with demersal trawls on the East China Sea continental shelf, and 96 nautical miles of track line were surveyed hydroacoustically. The echo sounder used during the survey was of a scientific type having echo integration capabilities and the computer system was programmed to obtain echo integration data for each depth stratum between the transducer and the bottom. The target strength of fish school(TS per 1kg) was estimated from the relationship between mean volume backscattering strength and catches caught by the demersal trawls. The results obtained can be summarized as follows: 1. Approximately 96 species were identified from survey catches. 2. The mean volume backscattering strength for the layer occupied by bottom trawls at 25 and 100 KHz were-63.9 dB and -67.3 dB, respectively. Then the average catch per unit time of each trawl haul was 58.8 kg/hour. 3. The mean volume backscattering strength for the entire layer between the transducer and the bottom at 25 and 100KHz were -61.9 dB and -67.0 dB, respectively. 4. The mean fish school target strength per unit weight(TS/kg) at 25 and 100 KHz were -23.6 dB/kg and -26.6 dB/kg, respectively.

TTo increase productivity of a strong extracellular alkaline protease (BCAP), stable strains of Bacillus clausii I-52 carrying another copy of BCAP gene in the chromosome were developed. Integrative vector, pHPS9-fuBCAP carrying BCAP promoter, ribosome binding site, signal sequence and active protease gene was constructed and transferred into B. clausii I-52, and integration of the constructed plasmid into chromosome was identified by PCR. An investigation was carried out on BCAP production by B. clausii I-52 and transformant C5 showing the highest relative activity of alkaline protease using submerged fermentation. Maximum enzyme activity was produced when cells were grown under the submerged fermentation conditions at $37^{\circ}C$ for 48 h with an aeration rate of 1 vvm and agitation rate of 650 rpm in a optimized medium (soybean meal 2%, wheat flour 1%, sodium citrate 0.5%, $K_2HPO_4$ 0.4%, $Na_2HPO_4$ 0.1%, NaCl 0.4%, $MgSO_47H_2O$ 0.01%, $FeSO_47H_2O$ 0.05%, liquid maltose 2.5%, $Na_2CO_3$ 0.6%). A protease yield of approximately 134,670U/ml was achieved using an optimized media, which show an increase of approximately 1.6-fold compared to that of non-transformant (83,960 U/ml). When the stability of transformant C5 was examined, the integrated plasmid pHPS9-fuBCAP was detected in the transformant after cultivation for 8 days, suggesting that it maintained stably in the chromosomal DNA of transformant C5.
