As the housing market is changing, there's a trend that the brand marketing through the TV-CM is increasing. Thus, this study purposes to identify the characteristics and the limit of the marketing on the housing market by analyzing the elements of marketing on TV-CM in the 2000's and comparing the representative business enterprises with each other. In the case of television advertisement, it is dominated by the emotional advertisement which is sensitive and image-oriented than the rational one. In addition, 1 pointed out some problems resulted from the transitional feature of the television advertisement and the gap between the real apartment and its brand image appeared on the advertisement, then I will present corresponding solutions.

Recently, the emotional design has become one of the central issues. The interest to Calligraphy also has increased. This study is to examine the effect of calligraphic TV title to viewers through questionnaires. As a result of the questionnaire analysis, calligraphic title makes a favorable impression on viewers. On the other hand, viewers have an antipathy to a drama program with a calligraphic title. The appropriate use of calligraphic title is requested. The viewers prefer that CM Super TV drama title is located to the right side in TV screen. They also prefer the animated moving title to colored background title. This study contributes to the further research about the correlation between TV commercial zap-rate and calligraphic title.

Background: The purpose of this study was to investigate whether tidal volume (TV) of 8 mL/kg without positive end-expiratory pressure (PEEP) and TV of 6 mL/kg with or without PEEP in pressure-controlled ventilation-volume guaranteed (PCV-VG) mode can maintain arterial oxygenation and decrease inspiratory airway pressure effectively during one-lung ventilation (OLV). Methods: The study enrolled 27 patients undergoing thoracic surgery. All patients were ventilated with PCV-VG mode. During OLV, patients were initially ventilated with TV 8 mL/kg (group TV8) without PEEP. Ventilation was subsequently changed to TV 6 mL/kg with PEEP ($5cmH_2O$; group TV6+PEEP) or without (group TV6) in random sequence. Peak inspiratory pressure ($P_{peak}$), mean airway pressure ($P_{mean}$), and arterial blood gas analysis were measured 30 min after changing ventilator settings. Ventilation was then changed once more to add or eliminate PEEP ($5cmH_2O$), while maintaining TV 6 mL/kg. Thirty min after changing ventilator settings, the same parameters were measured once more. Results: The $P_{peak}$ was significantly lower in group TV6 ($19.3{\pm}3.3cmH_2O$) than in group TV8 ($21.8{\pm}3.1cmH_2O$) and group TV6+PEEP ($20.1{\pm}3.4cmH_2O$). $PaO_2$ was significantly higher in group TV8 ($242.5{\pm}111.4mmHg$) than in group TV6 ($202.1{\pm}101.3mmHg$) (p=0.044). There was no significant difference in $PaO_2$ between group TV8 and group TV6+PEEP ($226.8{\pm}121.1mmHg$). However, three patients in group TV6 were dropped from the study because $PaO_2$ was lower than 80 mmHg after ventilation. Conclusion: It is postulated that TV 8 mL/kg without PEEP or TV 6 mL/kg with $5cmH_2O$ PEEP in PCV-VG mode during OLV can safely maintain adequate oxygenation.

This study was carried out to investigate dropping shock of household electric appliances during materials handling. Microwave oven($18{\ell}$), TV(16") and washing machine(6.2kg) were singled out as the study items. From the results of dropping test by KS A 1026(General Rules of Performance Testing for Packaged Freights), relative equations were gained as follow : y=0.0863x+10.032 for microwave oven, y=0.136x+7.85 for TV and y=0.214x+5.8 for washing machine (where y is G-factor and x is Dropping height). The maximum values of dropping shock during materials handling were measured to be $11{\sim}14G$ for microwave oven, $12{\sim}15G$ for TV and $10{\sim}12G$ for washing machine. The maximum shocks of microwave oven, TV and washing machine during materials handling were corresponding to dropping shocks of dropping height 45.98cm, 52.57cm and 28.97cm by KS A 1026.

The effect of magnetic field on VDT work has not been clarified yet, but many studies repoerted that magnetic field could cause of the cancers. Many developed countries have set the criteria of magnetic field and produce the VDT which has lower magnetic value. The purpose of this study was to measure the intensity of magnectic field from VDT. For this purpose three experiments were performed. The first was designed to measure the intensity of magnetic field by distances(30,60,90 cm) and directions. The second was to compare the intensities between VDT and Color TV. The last was to evaluate the eye protec- tion glasses. The reults showed that the intensity of magnetic field was lowered in proportion to the distance $r^{3}$and both lateral sides of the VDT marked high values compared to the frontal and back sides. On the same distance (30 cm) color TV marked high value to the VDT. But on the normal work distance (TV: 100 cm, VDT: 30 cm) there was little difference, Eye protection glasses could not protect the magnetic field physically.

In this paper, a digital terrestrial TV reception antenna which can be applied to the fade zone was designed and investigated. The proposed antenna was configured for a wire antenna structure with $16cm{\times}14cm$, and the antenna parameters are calculated by using the MoM method. The proposed antenna can be used to the receiver for domestic digital broadcast in UHF.

In March of 2014, after Eduwill's new TV commercial, Seo Kyung Seok, appeared as a model, unusually, various professional comedians have spontaneously made many TV ad parody contents. It is a kind of GCC (Gagman Created Contents), which is a content created by comedians if it is called User Created Contents (UCC) by a consumer voluntarily making contents. Various popular programs of TV stations such as tvN, KBS, SBS, MBC Eduwill TV commercial parody contents was broadcasted. Euduwill TV advertising parody contents can be classified as parody contents that mimic Eduwill CM songs and comic dancings by Seo Kyung Seok. In this study, we analyzed how the characteristics of class B culture such as 'twist' and 'satire' are reflected in Eduwill TV commercial parody, and discussed the correlation between advertisement, parody contents and socio-cultural phenomenon.

This paper presents the intra capacitance modeling according to the winding method, section bobbin and coil structure for hybrid choke coil capable of the EMI attenuation of broad bands from lower frequency bands to higher frequency bands and high frequency type common-mode choke coil capable of the EMI attenuation of high frequency band used in the EMI Block of LED-TV SMPS. In case of high frequency type CM choke coil, it can be explained the parasitic capacitance of A type and section bobbin type winding methods among them is much smaller than the other. The first resonant frequency of the proposed CM choke coil tends to increase as the parasitic capacitance becomes small and its impedance characteristics also show improved performance as the first resonant frequency increases. In case of hybrid choke coil using rectangular copper wire, it has investigated its parasitic capacitance compared to CM choke coil of conventional toroidal type becomes small. Also it has confirmed through the experiment results that CE margin and RE margin in frequency bands 0.5MHz to 5MHz and 30MHz to 200MHz are respectively 10dB and 15dB greater than that of conventional type in case of one stage EMI filter structure adopting hybrid choke coil compared to two stage EMI Filter structure using two of each CM choke coil used in the lower and higher frequency bands or two of CM choke coil used in only the lower frequency bands. In the future, the hybrid choke coil and CM choke coil of high frequency type show it can be practically used in not only LED/LCD-TV SMPS but also several applications such as LED Lighting, Laptop Adapter, Server Power Supply and so on.
