This paper presents a wide-frequency-range, low-power transceiver with an automatic impedance-matching calibration for TV-white-space (TVWS) application. The wide-range automatic impedance matching calibration (AIMC) is proposed for the Drive Amplifier (DA) and LNA. The optimal $S_{22}$ and $S_{11}$ matching capacitances are selected in the DA and LNA, respectively. Also, the Single Pole Double Throw (SPDT) switch is integrated to share the antenna and matching network between the transmitter and receiver, thereby minimizing the systemic cost. An N-path filter is proposed to reject the large interferers in the TVWS frequency band. The current-driven mixer with a 25% duty LO generator is designed to achieve the high-gain and low-noise figures; also, the frequency synthesizer is designed to generate the wide-range LO signals, and it is used to implement the FSK modulation with a programmable loop bandwidth for multi-rate communication. The TVWS transceiver is implemented in $0.13{\mu}m$, 1-poly, 6-metal CMOS technology. The die area of the transceiver is $4mm{\times}3mm$. The power consumption levels of the transmitter and receiver are 64.35 mW and 39.8 mW, respectively, when the output-power level of the transmitter is +10 dBm at a supply voltage of 3.3 V. The phase noise of the PLL output at Band 2 is -128.3 dBc/Hz with a 1 MHz offset.

The role of passive cell-mediated transfer of immunity against primary amoebic meningoen- cephalitis(PAME) in mice was studied. Waegleria fowleri, ITMAP 359, were cultured in CGVS medium. The ICR mice used were six week-old males of average weight of 15 g. Immunization was done by three intraperitoneal injections of $1{\times}10^6$ N. fowleri trophozoites at the interval of one week. Splenocytes were obtained from normal and immune mice spleens, and Ix107 cells were administered intraperitoneally into mice 3 days before challenge infection. Mice were infected intranasally with $7{\times}10^4$ N. fowleri trophozoites in a $3{\;}{\mu}l$ suspension under secobarbiturate anesthesia. Transplants of normal or immune splenocytes seem to alter the pattern of the PAME level- opment. The splenocytcs transferred from immune mice reduced the mortality rate in the JV. fowleri infected mice, as compared with the mice transferred with the same number of normal splenocytes or without splenocyte, The blastogenic response of the splenocytes to both lipopoly- saccharide and concanavalin A was elevated on duty 7 after infection the mice transinoculated with immune splenocytes. The serum antibody titers in the mice transferred with immune spleno- cytes were increased gradually from day 7 up to day 20 after infections by mean of ELISA. It is suggested that the transfer of splenocytes from immuniged mice conferred immunity against N. fowleri infection.

Even though there are some discrepancies in detail with the legal characteristic of the issuing bank's notice to the beneficiary of opening of the letter of credit, article 25 of "the Korean Private International Act(hereunder, 'KPIA')" can be applied to the legal relation between the issuing bank and the beneficiary or the negotiating bank. According to article 26 of the KPIA, if there is no agreement between the issuing bank and its opponent party as to the governing law issues, a state's law which has the closest relationship with the subject case may be applied. In the latter case, given the facts that the issuing bank plays important roles in every phasis of the sale of goods by the letter of credit, a law of place where the issuing bank's business premises is situated(the $lex$ $situs$) can be the applicable law. Meanwhile, "the Korean Supreme Court(hereunder 'KSC')" held that the beneficiary or the negotiating bank can claim any damages arising due to the refusal or deferred payment of the issuing bank, and the law which governs the above mentioned situation is the same law that is applicable to the legal relation between the issuing bank and the beneficiary or the negotiating bank. The main reason of the KSC's ruling is that the nature of the legitimate interest rate which is stated in article 3 of "the Act on Special Cases concerning Expedition etc. of Legal Proceeding(hereunder 'ASCELP')" is substantial matters, not procedural. Taking into account, however, that the main object of ASCELP lies in expedition of legal proceeding, prompt realization of people's rights and duties, and prevention of delayed legal proceeding, it is recommendable that ASCELP, instead of the law applicable to the legal relation between the issuing bank and the beneficiary or the negotiating bank, should be applied to the cases in which the malicious debtor's only and main purpose is delaying the legal proceedings. On the other hand, even if the issuing bank's duty of examination of the documents which were tendered by the beneficiary or the negotiating bank is restricted to the formality and strict conformity of the documents and not the substantiality of the documents, the issuing bank still has to examine the documents with due diligence that is required to the banks whose main business is sales of documents, not the real goods. In this regard, under the circumstances where the document lacked the regularity and/or the formality on its face because of the forgery of the document and where it was expected that an ordinary banker might have easily found any faults with the document, the issuing bank must compensate any parties for damages when it pays money without due diligence as a banker who engaged in the sales of documents.

The tracking of current location of residents is an essential requirement for context-aware service of smart houses. This paper presents a wireless sensor network system which could detect location transition such as entrance and exit to a room and also identify the user who passed the room, without duty of wearing any sort of tag. We designed new sensor node to solve the problem of short operation lifetime of previous work[1] which has two pyroelectric infrared (PIR) sensors and an ultrasonic sensor, as well as a 2.4 GHz radio frequency wireless transceiver. The proposed user identification method is to discriminate a person based on his/her height by using an ultrasonic sensor. The detection idea of entering/exiting behavior is based on order of triggering of two PIR sensors. The topology of the developed wireless sensor network system is simple star structure in which each sensor node is connected to one sink node directly. We evaluated the proposed sensing system with a set of experiments for three subjects in a model house. The experimental result shows that the averaged recognition rate of user identification is 81.3% for three persons. and perfect entering/exiting behavior detection performance.

Sexual dimorphism in birds refers to male-female differences in body size, plumage, color and/or behavior. In general, many seabirds, including the family of Laridae, are monomorphic in plumage-color, which makes the determination of sex difficult in the field because both parents also tend to share a great portion of parental care. The development of an inexpensive sexing tool facilitates understanding the degree of sex-specific parental care in the evolution of the life history. Here, we developed a non-invasive method for the determination of sex using the bill-head morphometric of known captive pairs and applied this tool to wild pairs to document factors underlying male-female parental care during the incubation period of Saunders's gulls (Saundersilarus saundersi). Males exhibited relatively larger bill-head ratios than their mates within naturally formed pairs in captivity, resulting in the determination of sex in12 wild pairs at the nest during the incubation period. Males and females equally shared the incubation role during the daytime, attending the nest at a high rate of 95%. However, the male's proportion of nest attentiveness greatly increased with time towards sunset, presumably reflecting the male duty for nighttime incubation. The present study provides a non-invasive method for the determination of sex in a monomorphic seagull species and highlights how male-female incubation behavior is associated with time of the day, rather than other ecological conditions.

The purpose of this study is to check the extent to which "instruction of physician or dentist" defined in the Medical Service Technologists, etc. Act is applied in relation to radiography examination procedures for radiological technologists. In addition, it is intended to present basic data on the requirement to revise the Medical Service Technologists, etc. Act in the radiological technologist's duty area and scope of work, The subjects of this study were radiological technologists with license, and the response data were collected after sending the questionnaire link written on the online questionnaire form. The final number of respondents were 1,018, and the response rate was 6.8%. Most of the negative responses were "I have never received 'instruction' for radiologic examination by a physician or dentist, including a radiologist in a medical environment." There were a high perception that "the professionalism in radiation examination on radiological technologists are higher than that of a physician or dentist." They answered that the current continuing education has a great impact on maintaining and continuing professionalism and learning new knowledge in the radiology field. In addition, the radiological technologists provide a very high level of education in areas related to radiography procedure ethics such as patient care, patient safety, and patient privacy protection, as well as specialized fields such as radiation-related examination methods, radiography examination dose, and patient exposure dose. Radiological technologists replied that they were receiving it consistently. In conclusion, in the current medical environment, the 'instruction' of a physician or dentist cannot be seen as being realistically performed. The phrase 'instruction' of a physician or dentist as defined in the Medical Service Technologists, etc. Act is considered inappropriate in respect of the fact that the state recognizes the qualifications of the medical service technologist through a license. It is thought that revision to a new term suitable for the current medical environment is necessary.
