Provided are a portable terminal for displaying a local service based on context awareness technology, and an operation method of the portable terminal. A typical system according to the present invention may include one or more indicators perceivable by individuals in proximity to a headset user that provide an indication that the headset is in use. The carrier is furthermore coupled at its lower end to the body or to a subframe, preferably via a link. The photoresist layer may be treated with a secondary exposure process, wherein the photoresist layer is developed in order to obtain a photoresist pattern layer. In addition, the invention relates to use of the coated molecular sieve and also to compositions comprising the molecular sieve and to use in producing apparatus such as, for example, electronic components and devices.
