E-BLP security model considers the reliability of the processes that are real subjects in systems. This paper deals with the implementation of the E-BLP model for secure embedded systems. Implemented EBSM(E-BLP Based Security Module) consists of three components: identification and authentication, access control and BRC(Dynamic Reliability Check) that checks the process behavior dynamically. Access Control of EBSM ensures unreliable processes not to access the sensitive objects and the DRC detects the buffer overflow attack by normal user. Besides, the performance overhead of the embedded system applying the EBSM is introduced.

The objective of this study was to determine effects of humic acid (HA) and blueberry leaf powder (BLP) supplementation in pig feed on productivity, blood profiles, and meat quality characteristics of longissimus muscle. The experimental design included six treatments: 1) CON, no addition; 2) T1, BLP 0.1%; 3) T2, BLP 0.2%; 4) T3, humic acid 2%; 5) T4: humic acid 2%+BLP 0.1%; and 6) T5: humic acid 2%+BLP 0.2%. HA and BLP supplementation in pig feed significantly increased average daily feed intake (ADFI) values (p<0.05). HA supplementation in pig feed had beneficial effects in lipid profiles without altering feed efficiency rate (FER). HA and BLP co-supplementation in pig feed decreased pH in longissimus thoracis (p<0.05). In addition, sensory characteristics were enhanced when pig feed was supplemented with HA and BLP without causing adverse effects in meat quality. Taken together, addition of HA and BLP in pig feed may produce functional meat products.

정보 보안의 세 가지 목적은 기밀성, 무결성, 유용성이다. 모든 정보 시스템에서 정보 보안에 관한 필요성이 대두되면서 기밀성뿐만 아니라 무결성도 보장하는 보안 모델이 필요하다. BLP와 Biba는 각각 기밀성과 무결성을 보장하는 보안 모델로서 BLP 모델이 무결성을 고려하지 않기 때문에, Biba 모델은 기밀성을 고려하지 않기 때문에 접근할 수 있는 정보에 한계가 있다. 본 논문에서는 여러 정보시스템 중에서 주로 군사 정보 시스템으로 구현된 BLP와 Biba 모델을 이용해서 기밀성과 무결성을 만족하는 보안 모델을 제시한다. BLP 모델과 Biba 모델을 결합함으로써 BLP 모델을 통해 기밀성을, Biba 모델을 통해 무결성을 보장한다

To develop a color stable and fine bamboo leaf powder (BLP) as a functional green biomaterial, bamboo leaf (BL) purchased from Sasa borealis and cultivated in Damyang, Jeonnam was treated with different conditions and BLP was evaluated. The four treatments comprised of boiling in water, in zinc chloride, sodium bicarbonate, and vinegar solutions, BLP4 was treated with 2% $ZnCl_2$ for 1 h, BLP5 was treated with 1% $ZnCl_2$ for 2 h, and BLP6 was treated with 1% $ZnCl_2+10%$ NaCl for 1 h. The particle size distribution, ash content, water binding capacity, and color change after heating in acidic solution were compared to commercial fine green tea (GTP) and bamboo leaf powders (CBLP). The particle size (cumulative 90%) of BLP was finest in BLP4 followed by BLP6 < BLP5 < GTP < CBLP. The water binding capacity of GTP was the highest and that of BLP was negatively correlated with particle size. After heating in acidic solution, the color of commercial GTP and CBLP changed from bright green to olive green, but the treated BLPs remained bright green. Especially, the -a (greenness) values for the commercial powders decreased from 11.2-13.6 to 3.1-3.8, while those of the treated BLPs did not change.

To design and develop secure operating systems, the BLP (Bell-La Padula) model that represents the MLP (Multi-Level Policy) has been widely adopted. However, user\`s security level in the most developed systems based on the BLP model is inherited to a process that is actual subject on behalf of the user, regardless whatever the process behavior is. So, there could be information disclosure threat or modification threat by malicious or unreliable processes even though the user is authorized in the system. These problems can be solved by defining the subject as (user, process) ordered pair and by defining the process reliability. Moreover, when the leveled programs which exist as objects in a disk are executed by a process and have different level from the process level, the security level decision problem occurs. This paper presents an extended BLP (E-BLP) model in which process reliability is considered and solves the security level decision problem. And this model is implemented into the Linux kernel 2.4.7.

The ideal method of safety evaluation is to verify results of execution against all possible operations within operating system, but it is impossible. However, the formal method can theoretically prove the safety on actual logic of operating system. Therefore we explain the contents of the art of the safety verification of security kernel, and make a comparative study of various standardized formal verification tools. And then we assigned PVS(Prototype Verification system) of SRI(Stanford Research Institute) to verify the safety of a modified BLP(Bell & LaPadula) model, the core access control model of multi-lavel based security kernel. Finally, we describe formal specification of the revised BLP model using the PVS, and evaluate the safety of the model by inspecting the specification of the PVS.

Fifteen microbes have been isolated from Jangja pond in Kuri-Si, Kyeonggi-Do. Among them, two strains showed excellent COD removal from wastewater, which were named Pseudomonas sp. BLP2052 and Flavobacterium sp. BLP20515, respectively. Optimal pH and temperature for the cell growth were 7.0 and $30^{\circ}C$ for both strains. Pseudomonas sp. BLP2052 and Flavobacterium sp. BLP20515 was applied to the reactor to treat wastewater and 66.0% and 65.7% COD (chemical oxygen demand) removal was achieved, respectively. Comparing these results to the case of applying mixed microbes present in Jangja pond, COD removal rate was 15% less. But when adding the selected microbes to the wastewater containing mixed microbes, COD removal rate increased by 5%. After 84 hour operation, we achieved 85.6% COD removal. When inhibitors were added less than 100 ppm, during the microbial wastewater treatment, Fe, Zn, Al, phenol and Cr influenced microbial activity more deterioratively in order. In the case of over 300 pm, Cr, Fe, Zn, Al and phenol showed severe deteriorative effect in order.

The electrical performance of a package is extremely important for high speed digital system operations. CSP(chip scale package) is known to have better electrical performance than the convnetional packages. In this paper, the electrical performance of the BLP(bottom leaded plastic) package, a kind of CSP, has been alayzed by both simulation and real measurement. The electrical perfdormance of a BLP was compared with that of the conventioanl TSOP(thin small outline package). The leadinductanceand lead capacitance were used for the comparison purposes. The new BLP design provides much better electrical performance that TSOP package. It has about 40% favorable parameter values.

안전한 운영체제를 개발하기 위한 제안된 모델중 대표적인 BLP(Bell&LaPadula)모델은 주체(사용자)의 보안등급이 접근주체인 프로세스에 그대로 상속됨으로서 악의적인 프로세스에 의한 정보의 흐름, 변조, 누출 등의 위협을 고려하지 않는 단점을 지니고 있다. 본 논문에서는 프로세스를 신뢰영역과 비 신뢰영역으로 구분하고 악의적인 행위를 유발할 수 있는 프로세스들의 접근을 강력히 통제하는 프로세스 기반의 확장된 BLP 모델을 제안하고 시스템에 적용을 위한 아키텍쳐를 설계한다.

Bacterial leaf pustule (BLP) caused by Xanthomonas axonopodis pv. glycines is a serious disease to make pustule and chlorotic haloes in soybean [Glycine max (L). Merr.]. While inheritance mode and map positions of the BLP resistance gene, rxp are known, no sequence information of the gene was reported. In this study, we made five near isogenic lines (NILs) from separate backcrosses (BCs) of BLP-susceptible Hwangkeumkong $\times$ BLP-resistant SS2-2 (HS) and BLP-susceptible Taekwangkong$\times$ SS2-2 (TS) through foreground and background selection based on the four-stage selection strategy. First, 15 BC individuals were selected through foreground selection using the simple sequence repeat (SSR) markers Satt486 and Satt372 flanking the rxp gene. Among them, 11 BC plants showed the BLP-resistant response. The HS and TS lines chosen in foreground selection were again screened by background selection using 118 and 90 SSR markers across all chromosomes, respectively. Eventually, five individuals showing greater than 90% recurrent parent genome content were selected in both HS and TS lines. These NILs will be a unique biological material to characterize the rxp gene.
